Cisco 350-601 Implementing Cisco Data Center Core Technologies (DCCOR) Exam Practice Test

Option D is the recommended method to configure the SAN boot when the storage system maps the source WWPN to a unique LUN. This method creates a SAN boot policy in which every initiator is mapped to a different target LUN, which ensures that each server boots from its own LUN and avoids any conflicts or errors. The other options are either incorrect or incomplete for the task. References:

Cisco NX-OS Data Management Engine (DME) model is a hierarchical representation of the configuration and operational state of the Cisco NX-OS devices. It supports multiple protocols for accessing and manipulating the data, such as NETCONF, RESTCONF, gRPC, and CLI. Among these, NETCONF is the recommended technology for managing a large-scale data center and collecting information from multiple Cisco NX-OS devices using DME model, because it provides a standard, secure, and scalable way of communicating with network devices. References := [Cisco NX-OS Data Management Engine Model]

A full state configuration backup in Cisco UCS Manager includes a snapshot of the entire system, which is stored as a binary file. This backup type is ideal for disaster recovery as it can restore or rebuild the configuration on the original fabric interconnect or recreate the configuration on a different fabric interconnect. It is important to note that this backup type cannot be used for an import but is specifically designed for system restoration.

References:

• Cisco’s official documentation on “Backing Up and Restoring the Configuration” provides a detailed guide on the backup types and procedures within Cisco UCS Manager1.
• The “Cisco UCS Manager Administration Management Guide 4.2” further elaborates on backup operations, considerations, and the system restore process

Bidirectional PIM is designed for scenarios where there are many sources and receivers that need to communicate with each other, such as in videoconferencing. Unlike traditional PIM sparse mode, which creates both (,G) and (S,G) entries, Bidirectional PIM only allows the (*,G) entry for the shared tree and does not build an (S,G) entry. This approach reduces the number of mroute state entries, conserving resources. Traffic can flow up and down the shared tree in Bidirectional PIM, and there is no RPF check; instead, a Designated Forwarder (DF) is used to prevent loops. References := Multicast Bidirectional PIM - NetworkLessons.com

The action that must be performed before renumbering a Cisco UCS chassis is to re-acknowledge the chassis. Re-acknowledging the chassis is a process that forces the Cisco UCS Manager to rediscover the chassis and its components, such as the I/O modules, the power supplies, and the fans. Re-acknowledging the chassis is necessary before renumbering the chassis, because it ensures that the Cisco UCS Manager has the latest information about the chassis and its configuration. Re-acknowledging the chassis also allows the network engineer to apply any pending configuration changes or policies to the chassis and its components. Re-acknowledging the chassis can be done from the Cisco UCS Manager GUI or CLI, by selecting the chassis and choosing the Re-Acknowledge option. References :=

Cisco Data Center Network Manager (DCNM) is designed to help manage all NX-OS network deployments, which includes LAN fabrics, SAN fabrics, and IP Fabric for Media (IPFM) networking in the data center. DCNM provides prebuilt templates that can be used to customize fabric deployments, allowing for a more streamlined and efficient setup process. These templates include best-practice policy templates for Easy Fabric Mode and support for Python scripting for more complex policy templates, facilitating the customization and automation of fabric deployments.

 NFS, or Network File System, is a protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. NFS uses remote procedure calls (RPC) over TCP/IP for transport4. References := Wikipedia article on Network File System (NFS)4.

By default, Cisco UCS Manager excludes local disks from a host firmware package to avoid data loss or corruption during firmware upgrades. The host firmware package contains firmware for other components like network interface controllers, storage controllers, etc., but excludes local disks as they might contain sensitive data.

The configuration in Option C likely involves setting the port to N Port and enabling Trunk Mode Active. This setup is necessary for establishing a VSAN trunk, as it allows the port to actively negotiate with the other switch to transmit and receive frames in multiple VSANs over the same physical link1.

References := For detailed steps and guidelines on configuring VSAN trunking on Cisco switches, you can refer to the official Cisco documentation, such as the Cisco MDS 9000 Series Fabric Switches Configuration Guides

During an In-Service Software Upgrade (ISSU) on Cisco Nexus 9000 Series Switches, the LACP peer session is designed to remain up without any renegotiation or reset. This is because ISSU is a process that allows for software upgrades without disrupting the normal operation of the network. The default LACP timers and the ISSU process are designed to work together to maintain the session state even during the upgrade process. The Nexus upgrade process will force the chassis itself to upgrade disruptively if LACP fast is used, which is not the default setting. A disruptive upgrade means the chassis itself will fully reload, impacting all ports on the switch, not just the LACP fast ones. However, with the default aging timers, the LACP peer connection should not be affected1.

POAP is an automatic provisioning and zero-touch deployment feature that assists device owners in the

initial deployment and configuration of Nexus switches.

The feature works by checking for a local configuration script. If the script has been deleted, the switch has

been reset to factory settings, or this is the first boot-up, the POAP daemon will connect to a preset list of

servers to download an initial configuration file.

To perform this operation, the switch must first obtain an IP address from a local DHCP server. POAP

configuration settings can also be passed through the DHCP response.

Which conditions should be verified, so they need to be TRUE. Like no startup (A) and bootup (B). C means

that it needs to miss a license file and E means it needs to miss an NX-OS image.

To use SaaS to manage Cisco computing, you need to have a Cisco Intersight account and a device/claim ID for each device that you want to manage. Cisco Intersight is a cloud-based platform that provides unified management, automation, and analytics for Cisco data center products. A device/claim ID is a unique identifier that is generated when you register a device with Cisco Intersight. You can use the device/claim ID to claim the device and add it to your Intersight account. Once you claim the device, you can monitor, configure, and troubleshoot it from the Intersight dashboard. References: For more information on how to use SaaS to manage Cisco computing, please refer to the following resources:

 To meet the requirements of using the secondary interface and then falling back to the primary interface when it becomes available again, the engineer should enable the Uplink failover option in the vNIC properties of the Cisco UCS Cisco Integrated Management Controller (CIMC) network adapter for a standalone Cisco C-Series server. The Uplink failover option allows the vNIC to switch to the secondary interface in case of a failure in the primary interface, and then switch back to the primary interface when it recovers. The Uplink failover option also allows the engineer to configure the Fallback Timeout value, which determines how long the vNIC waits before switching back to the primary interface. In this case, the Fallback Timeout value is set to 600 seconds, which means the vNIC will wait for 10 minutes before falling back to the primary interface. References :=

 The update() method in Python is used to add an element to a dictionary. It takes either another dictionary object or an iterable of key-value pairs and adds them to the dictionary. If the key is already present in the dictionary, update() will update the key with the new value. Option B correctly uses the update() method to add the new ‘N9K-Spine-2’: ‘1498323434’ key-value pair to the switch_id_list dictionary.

References: For more information on modifying dictionaries in Python, the official Python documentation provides comprehensive guidelines and examples. It’s a valuable resource for understanding the behavior of dictionary methods like update().

The impact of the EPLD update of the supervisor module on the Cisco MDS 9000 switches is that the redundant supervisor takes over while the EPLD update is in progress and there is no service disruption. EPLD (Electronic Programmable Logic Device) is a firmware component that controls the functionality of various hardware modules on the switch, such as the supervisor, line cards, and fabric modules. The EPLD update is performed to enhance the performance and features of the hardware modules, and to fix any bugs or issues. The EPLD update process requires a reload of the affected module, which can cause a temporary loss of connectivity and traffic. However, if the switch has a redundant supervisor module configured in high availability mode, the EPLD update can be performed without any service disruption. This is because the redundant supervisor takes over the control plane functions while the active supervisor is being updated, and then switches back to the active supervisor when the update is completed. The EPLD update does not affect the data plane traffic, as the line cards and fabric modules continue to forward packets during the update process. References :=

 The correct configuration to generate a syslog message when CPU utilization is higher than 60% is option A. This configuration uses the Event Manager Applet feature of Cisco IOS to monitor the CPU utilization via SNMP. When the CPU utilization exceeds 60%, the specified action is triggered, which in this case is to send a syslog message with a priority of notifications and the message “cpu high”. The event snmp oid command specifies the OID to be monitored, and the entry-op gt 60 part of the command sets the condition for triggering the action when the value is greater than 60. The poll-interval 5 specifies that the SNMP OID will be polled every 5 seconds.

The MAC address that is an HSRP version 2 address is 0000.0C9F.F0C8. HSRP (Hot Standby Router Protocol) is a protocol that provides redundancy and load balancing for IP networks by allowing multiple routers to share a virtual IP address and MAC address. HSRP version 2 supports up to 4096 groups, and uses a different MAC address format than HSRP version 1. The MAC address format for HSRP version 2 is 0000.0C9F.FXXX, where XXX is the hexadecimal value of the group number. For group 200, the hexadecimal value is C8, so the MAC address is 0000.0C9F.F0C8. References :=

 Before enabling a Cisco UCS Manager domain for Cisco Intersight connectivity, you must configure the DNS servers and the NTP servers for the domain. The DNS servers are required to resolve the hostname of the Cisco Intersight service (svc.intersight.com) and the NTP servers are required to synchronize the time between the Cisco UCS Manager and the Cisco Intersight service. These settings ensure that the Cisco UCS Manager can establish a secure and reliable connection with the Cisco Intersight service and register the domain with the Cisco Intersight account.

 Multipathing iSCSI traffic is a technique to provide redundancy and load balancing for iSCSI connections between a server and a storage device. Multipathing can be achieved by using multiple initiators, multiple targets, or both. However, some design choices are more optimal than others, depending on the network topology and the capabilities of the devices involved. Option C, “dual initiators to a single target with bonded interfaces,” is a recommended design choice because it provides the following benefits:

• It allows the server to use two separate network interface cards (NICs) to connect to the same iSCSI target, which increases the bandwidth and availability of the connection.
• It enables the use of link aggregation or bonding on the target side, which combines multiple physical interfaces into a logical interface that can handle more traffic and tolerate link failures.
• It simplifies the configuration and management of the iSCSI sessions, as there is only one target to deal with, and the multipathing software can handle the path selection and failover.

References := The information is based on the Cisco Data Center Core Technologies (DCCOR) course, which covers the implementation of data center technologies including network, compute, storage network, automation, and security. More details can be found in the course material and official Cisco documentation on iSCSI multipathing

The Bash script is designed to loop through the available namespaces and output all registered interfaces within the Cisco NX-OS Guest Shell. The correct code snippet to complete the script is option C, ifconfig "$ns". This command will display the network configuration for each namespace, allowing the engineer to view all registered interfaces.

References: The use of ifconfig in conjunction with namespace variables is a common practice in network scripting to retrieve interface information. For more detailed information on scripting in Cisco NX-OS, you can refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

 In Cisco UCS Manager, RBAC (Role-Based Access Control) is used to define what users can do within the system. The roles that can be used to configure LAN Connectivity policies are typically those with administrative privileges. The network-admin role has the necessary privileges to configure network-related settings, including LAN Connectivity policies. Similarly, the admin role has full administrative rights over all system configuration aspects, which also encompasses LAN Connectivity policies. The other roles listed do not have the appropriate level of access for this task.

References: The information is aligned with the Cisco Data Center Core Technologies source book, which details RBAC roles and their permissions within the Cisco UCS Manager environment

To establish a VSAN trunk between Switch 1 and Switch 2, you would typically configure E Port with Trunk Mode On. This is because Switch 1 is already configured with an E port in Trunk Mode Auto, and for trunking to be established, the other switch should also be set to trunk mode but with a static configuration (On) to ensure compatibility and trunk formation.

To install the “Markdown” package from the Python package manager on a Cisco Nexus 93108 Series Switch, the engineer must ensure that the guest shell has internet access to reach the Python package repository. This is achieved by adding the nameserver configuration to /etc/resolv.conf, which allows the system to resolve domain names into IP addresses. After configuring the nameserver, the engineer must run the command sudo chvrf management pip install Markdown to install the package within the management Virtual Routing and Forwarding (VRF) context, which has access to the internet.

References: = For more information on managing packages in the guest shell of Cisco Nexus switches, refer to the Cisco Nexus 9000 Series NX-OS Programmability Guide.

To enable port security on all Cisco MDS series switches in the fabric and avoid the extensive manual configuration of the switch ports, the network engineer must activate the CFS (Cisco Fabric Services) distribution and enable the auto-learning port security feature on a per-VSAN basis. CFS is a protocol that allows the switches to distribute and synchronize configuration information across the fabric. By activating the CFS distribution for port security, the network engineer can propagate the port security configuration to all the switches in the fabric automatically, without having to configure each switch individually. The auto-learning port security feature allows the switches to learn and store the port security information of the devices that are already logged in and authorized on the ports, and prevent any unauthorized devices from logging in. The auto-learning port security feature can be enabled on a per-VSAN basis, which means that the port security information is specific to each VSAN and does not affect other VSANs. This provides more flexibility and granularity for the port security configuration. References :=

In the context of Cisco Nexus switches, VRF (Virtual Routing and Forwarding) is used to create multiple virtual routing tables within a single switch. By using the default VRF for the scheduler job, the engineer ensures that the TFTP server, which is reachable in the global routing table, can be accessed without the need for additional VRF configuration. This simplifies the backup process and avoids potential issues with VRF-specific routing that could prevent access to the TFTP server.

The command checkpoint file before_maintenance is used to create a checkpoint of the current running configuration with the specified file name. The command rollback running-config file before_maintenance atomic ensures that the rollback of the checkpoint to the running configuration only occurs if there are no errors during the process. This is essential for maintaining the stability of the switch during maintenance operations.

 ARP suppression is a feature used in VXLAN/EVPN environments to optimize ARP responses and reduce unnecessary ARP broadcasts across the fabric. When ARP suppression is enabled, the local VTEP (VXLAN Tunnel Endpoint) can respond to ARP requests for known IP-to-MAC address bindings, which are learned via the BGP EVPN control plane. This prevents the need for ARP broadcasts to be sent across the entire VXLAN fabric, thus optimizing the ARP response mechanism and reducing broadcast traffic1.

• Community discussions on ARP suppression in VXLAN/EVPN

The command “ldap-server host 10.10.2.2 enable-ssl” is used to configure AAA authentication on an MDS 9000 switch with an LDAP server located at the IP 10.10.2.2. This command ensures that the data sent to the LDAP server is encrypted using SSL, which is a protocol for securing network communication.

References: For more information, refer to the Cisco Data Center Core Technologies (DCCOR) study guide or source documents, specifically the sections covering AAA authentication configuration and LDAP server integration with MDS 9000 switches.

 Option D and C are the correct policies that must be configured to meet the requirements. A Maintenance Policy specifies how the changes are applied when a service profile is associated or disassociated with a server or when an updated service profile is applied to a server. A Power Control Policy allows users to select how Cisco UCS Manager should restore power to the servers in a chassis after the chassis loses power. References:

 Microsegmentation is a feature of ACI that allows granular control of traffic between endpoints based on vCenter VM attributes, such as name, guest OS, or network adapter type. Microsegmentation works by creating a micro-EPG for each VM and applying contracts and policies to the micro-EPGs. When microsegmentation is enabled, ACI performs distributed switching and routing on the ESXi hosts using the Cisco Application Virtual Switch (AVS) or the Cisco Application Virtual Edge (AVE). This allows ACI to enforce policies at the hypervisor level, without requiring any changes to the physical network or the VM configuration. References :=

Option C and E are the correct requirements when planning a Cisco HyperFlex All Flash standard cluster installation using three HX240c M5 servers. Option C states that if the Jumbo MTU option in the HyperFlex installer is enabled, then jumbo frames must also be enabled on the upstream switches, which is true for optimal performance and compatibility. Option E states that the servers must be discovered, unassociated, and connected to each fabric interconnect, which is also true for the cluster installation process. The other options are either false or not applicable for the scenario. References:

 The command set in Option C is the correct configuration for a Fibre Channel port channel on a Cisco Nexus 9000 Series Switch that meets the specified requirements. The commands in this option perform port-channel protocol negotiation with peer ports using the “channel mode active” command, explicitly configure the trunk mode with “switchport trunk mode on,” and allow VSANs from 10 to 20 with “switchport trunk allowed vsan 10-20.”

References: For further details, you would refer to the Cisco Nexus 9000 Series NX-OS SAN Switching Configuration Guide, which provides instructions on configuring Fibre Channel port channels and related settings.

 Static ingress replication is a method used in VXLAN environments where the replication of multicast, broadcast, and unknown unicast traffic is manually defined. In the context of Cisco Data Center Core Technologies, Option A implements static ingress replication by explicitly specifying peers for replication using the ingress-replication protocol static command followed by the peer-ip command to define the IP address of the replication peer. This configuration is necessary when multicast routing is not an option in the underlay network.

References := For further details, one would typically refer to Cisco’s official documentation on VXLAN configurations and the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) study materials, which provide in-depth explanations on the setup and management of network overlays including static ingress replication.

DTLS (Datagram Transport Layer Security) is designed to provide security for datagram-based applications by allowing them to communicate in a way that is designed to prevent eavesdropping, tampering, or message forgery. It is suitable for securing JSON encoded telemetry data sent to an external collector1.

 To make a capture task persistent after a reboot, the command sequence in Option C should be used. This typically involves enabling the service to start at boot time using systemctl enable and then starting the service with systemctl start. This ensures that the capture task will automatically resume after the system is rebooted4

 In a VXLAN-based data center interconnect scenario where the transport supports a maximum MTU of 1554 bytes and does not support outbound traffic replication, the engineer must use BGP to announce host reachability. This allows for the advertisement of host routes over the BGP session, enabling remote VTEPs to learn about hosts in the interconnected data centers without relying on traffic replication.

 Promiscuous mode (D) allows a virtual machine to observe all traffic on the virtual switch, which is necessary for the virtual machine to receive all frames. VLAN (E) is used to map the frames to a specific Layer 2 network. These settings ensure that the virtual machine receives all traffic for the specified VLAN, fulfilling the requirements stated in the question1.

References: The configuration details and the role of these settings can be found in the Cisco documentation related to VDS port group parameters managed by APIC

User A, having both the default role and Custom-Role-B, will be authorized to configure NTP, SSH, and DPVM. The default role allows configuration of NTP and SSH, while Custom-Role-B specifically permits DPVM configuration and denies TACACS+.

 NX-API is a feature that enables the use of JSON and XML encoding when a Cisco Nexus 7000 series switch is deployed. NX-API is a RESTful API that allows external applications to communicate with the switch using HTTP/HTTPS requests and responses. NX-API supports JSON and XML as the data formats for encoding and decoding the requests and responses. By using NX-API, external applications can access and configure the switch features and functions without using the CLI or SNMP. NX-API also provides a sandbox mode that allows users to test and validate their API calls before applying them to the switch. References :=

Option C meets the security requirements for the Cisco UCS C-Series Server. It disables unencrypted communication by enabling HTTPS, sets the session timeout to 900 seconds (15 minutes), redirects HTTP to HTTPS to divert unencrypted traffic, and changes the SSH port to a nondefault value (2022), which is essential for CLI-based management.

In an OSPF Not-So-Stubby Area (NSSA), external routes can be introduced into the area by an NSSA Autonomous System Boundary Router (ASBR) as type 7 LSAs. These LSAs are unique to NSSA areas and allow for the injection of external routes in a limited fashion. An NSSA Area Border Router (ABR) then translates these type 7 LSAs into type 5 LSAs, which are propagated throughout the OSPF domain. References := Configure the OSPF Not-So-Stubby Area (NSSA) - Cisco

The code snippet in Option C correctly sets up a local user named “tacuser” with an expiration date of 22 November. In the NX-OS API, the “expiresAt” attribute is used to specify the expiration date for a user account, which should be formatted in the ISO 8601 standard. The snippet provided in Option C, "expiresAt": "2021-11-22T00:00:00.000+00:00", correctly applies this format to set the expiration date to 22 November 2021. References := For further details, refer to the Cisco Data Center Core Technologies source documents or study guide available on the official Cisco Learning Network Store and Cisco’s solution listings for data center virtualization.

 Option C is the correct answer. Puppet is an open-source software configuration management tool that is used for deploying, configuring, and managing servers. It allows for the centralized management of various system configurations and aligns UCS servers to their desired state by periodically acquiring configurations from a centralized server. References:

The attribute that must be selected to implement microsegmentation of endpoints within the same IP subnet using a network-based attribute that allows IP subnet independence is the Tag attribute. The Tag attribute is a user-defined attribute that can be assigned to endpoints based on any criteria, such as location, function, or security level. The Tag attribute can be used to create microsegmentation policies in ACI, which define the rules for communication between endpoints within the same or different bridge domains. The Tag attribute enables IP subnet independence, which means that the microsegmentation policies are not tied to the IP subnet of the endpoints, and can be applied across different subnets or even different fabrics. The Tag attribute also simplifies the management and scalability of microsegmentation policies, as it does not require the use of IP addresses or MAC addresses to identify endpoints. References :=

 NFS uses XDR (External Data Representation) as the communication method for requests between servers and clients. XDR is a standard format for encoding and decoding data that is exchanged between different systems. XDR allows NFS to handle data with different byte orders, word sizes, and data types. XDR is also used by ONC RPC, which is the underlying protocol for NFS. XDR ensures that the data is represented consistently and correctly across different platforms and architectures. References :=

 Increasing the vPC delay restore timer can help prevent packet loss during a vPC peer switch reload. This timer delays the restoration of vPCs after a peer link recovery, allowing enough time for all the systems to stabilize and for routing protocols to converge, thus avoiding potential packet loss1.

When you run the install commit  command on a Cisco Nexus 9000 Series Switch, it schedules the new package to be used after the next reboot of the switch. This means that the current running configuration isn’t immediately affected by the new package, but it will be incorporated once the switch is restarted.

The VLANs capable of being assigned on vPC interfaces are those that are active on the vPC peer-link. According to the exhibit, the active VLANs on the vPC peer-link range from 100 to 105. However, VLAN 105 is not listed under the individual port statuses for Po7 and Po8, which indicates that VLAN 105 is not actively participating in the vPC. Therefore, the VLANs that can be assigned to vPC interfaces are 100-104.

References := For a detailed understanding of vPC configurations and VLAN assignments, one should refer to the Cisco Data Center Core Technologies study materials, which provide comprehensive coverage of vPC operations and best practices.

 In a Cisco NX-OS environment, Ansible requires the NX-API to be enabled for HTTP/HTTPS protocol communication. NX-API is a REST-like API for NX-OS, providing a method for external applications to access the switch over HTTP/HTTPS, allowing for both CLI and simple object-based programming. This is necessary for Ansible to manage the device and execute automation tasks over these protocols.

To prevent loops from occurring accidentally on a switch interface designated for host connectivity, the best practice is to enable Spanning Tree Protocol (STP) protections. Option A, which includes the command spanning-tree guard loop, is the correct configuration to apply. This command enables Loop Guard, a feature that prevents alternate or root ports from becoming designated ports due to a failure that leads to a unidirectional link. If a port stops receiving Bridge Protocol Data Units (BPDUs), Loop Guard puts the port into an STP loop-inconsistent state, effectively preventing potential loops.

References := This information is aligned with the best practices for loop prevention as described in Cisco’s Data Center Core Technologies materials. For further details, refer to the study guide or source documents related to STP and its security features within the Cisco Data Center Core Technologies curriculum.

On Nexus switches, the equivalent command to save the configuration to NVRAM is ‘copy running-config startup-config’. The ‘write memory’ command is specific to Catalyst switches and is not used on Nexus switches.

When configuring traffic capture to investigate issues such as buffering problems and packet drops, it’s important to consider where to place the capture points. Typically, you would configure a SPAN (Switched Port Analyzer) or RSPAN (Remote SPAN) session to mirror the traffic from the affected areas to a monitoring device. The configuration would involve:

• Identifying the source ports or VLANs where the issues are observed.
• Specifying a destination port connected to a network analyzer like Wireshark.
• Ensuring the destination port is not used for regular network traffic.

For example, a basic SPAN session configuration might look like this:

monitor session [session_number] source interface [interface_id]

monitor session [session_number] destination interface [destination_interface_id]

To create a certificate request in Cisco UCS Manager, the correct command set involves navigating to the security scope, selecting the appropriate keyring, and then creating the certificate request with the specified IP address and subject name. The commands in option D correctly follow this procedure. The commit-buffer command is used to commit the changes in UCS-A, which is the primary fabric.

References: This process is documented in the Cisco UCS Manager certificate management guidelines, which provide step-by-step instructions on creating certificate requests using the CLI

 The System Configuration backup type in Cisco UCS Manager is specifically designed to back up system settings such as user names, roles, and locales. This XML file does not include the actual data on the servers but captures all the system configuration settings, which can be imported to the original fabric interconnect or to a different one. However, it cannot be used for a system restore.

The correct command set for configuring AAA to use CHAP with MD5 hashing and to share the RADIUS configuration across MDS switches involves using the aaa authentication login command with the radius keyword and enabling CHAP. The radius distribute command is used to share the RADIUS configuration automatically with other MDS switches in the environment.

References:

• Cisco MDS 9000 Series Security Configuration Guide1
• Configuring FC-SP and DHCHAP2

Please note that the actual commands may vary based on the specific requirements and the version of the Cisco NX-OS software running on your switch. It’s always best to consult the latest Cisco documentation or a certified Cisco technical expert for the most accurate information.

The command in Option D correctly uses a loop to iterate over the range {1…5}, which represents the first five interfaces. The dohost command is used to send commands to the host Cisco Nexus switch from the Guest Shell. The syntax interface eth1/$x and description Server$x within the loop sets the description for each interface eth1/1 to eth1/5 to “Server1” to “Server5” respectively.

Here’s the command from Option D formatted for clarity:

[guestshell@guestshell ~]$ for x in {1..5}; do

dohost "conf t" ;

interface eth1/$x;

description Server$x;

done

This command will configure the description for each of the first five Ethernet interfaces with the respective server number as part of the description.

 To reduce disruptions during a major software upgrade on a Cisco Nexus Series switch, technologies like VDC (Virtual Device Contexts) and vPC (Virtual Port Channels) can be implemented. VDC allows for the partitioning of a single physical device into multiple logical devices, which can be managed and operated independently. This means that one VDC can be upgraded while others remain operational, minimizing downtime. vPC enables the linking of two switches to create a single logical switch, providing redundancy and allowing for one switch to be upgraded while the other maintains the network operations1.

The Maintenance Mode Profile feature in Cisco Nexus 7000 Series Switches is used to ensure a controlled shutdown of ports and graceful termination of routing protocols before performing a software upgrade12. References := Cisco Nexus 7000 Series NX-OS Software Upgrade and Downgrade Guide12.

SPAN (Switched Port Analyzer) is a feature that allows network traffic from one or more source ports to be mirrored to a destination port for analysis. When configuring SPAN on a Cisco Nexus 5000 Series switch, two characteristics must be considered:

• A SPAN source port can be monitored in multiple SPAN sessions. This means that the same port can send traffic to different destination ports for different purposes or applications.
• A SPAN source port cannot be a destination SPAN port. This means that a port cannot receive traffic from another port that it is already monitoring. This prevents loops and conflicts in the SPAN configuration.

 A full state backup of a Cisco UCS Manager database performs a complete binary dump of the database as a .bin file, not a .txz or a .sql file. A full state backup contains all of the configurations and all of the runtime states and statuses of the Cisco UCS domain, but not the passwords. A full state backup can be used to restore the Cisco UCS Manager database to the same or a different fabric interconnect, as long as the hardware configuration is identical. References := Implementing and Operating Cisco Data Center Core Technologies (DCCOR) - Cisco, Chapter 5: Implementing Cisco Unified Computing System Rack Servers, Section: Back Up and Restore the Cisco UCS Manager Database

The ‘protect’ violation mode in port security is designed to drop packets with unknown source MAC addresses without affecting the interface’s state. This mode ensures that traffic from already learned MAC addresses continues to be forwarded while preventing any new MAC addresses from forwarding traffic until a sufficient number of secure MAC addresses are removed or the maximum count is increased. This configuration aligns with the requirement to not affect already learned MAC addresses.

References := For further reading and detailed understanding, refer to the Cisco Data Center Core Technologies study guide and source documents available on the Cisco Learning Network Store and Cisco’s official solutions page for data center virtualization.

Options D and E are the correct firmware packages that are included in the Cisco UCS C-Series Rack-Mount UCS-Managed Server Software bundle. The bundle contains the firmware for the CIMC (Cisco Integrated Management Controller) and the BIOS (Basic Input/Output System) of the server. The other options are either not part of the bundle or not applicable for the server. References:

A strict CoPP (Control Plane Policing) policy is designed to manage the traffic flow of control plane packets to protect the control plane of routers and switches from being overwhelmed by unnecessary or malicious traffic. When a ping sweep, which involves sending ICMP echo requests to multiple hosts to identify live devices on a network, is performed on a network connected through a switch with a strict CoPP policy, excess ICMP packets can be dropped to prevent them from consuming excessive resources. References: Cisco Data Center Core Technologies source documents or study guide

• Setting the RADIUS source interface to be mgmt0 for group RAD1 and VLAN 22 for group RAD2 © ensures that login requests from the console and SSH are sourced from the correct interfaces and reach the appropriate RADIUS server.
• Configuring the authentication login to use group RAD1 for console and group RAD2 for remote access (D) directs the switch to use the specified RADIUS server groups for the respective login methods, aligning with the user’s requirements.

These configurations ensure that management access via console and SSH is authenticated through the designated RADIUS servers as intended. It’s important to apply these settings correctly in the switch’s configuration to achieve the desired access control.

Cisco HyperFlex uses the Network File System (NFS) protocol for sharing data among nodes in a VMware vSphere environment. NFS is a distributed file system protocol that allows a user on a client computer to access files over a network in a manner similar to how local storage is accessed. This protocol is commonly used in virtualized environments for ease of data sharing and management12.

References: The use of NFS in Cisco HyperFlex environments is documented in Cisco’s official installation guides and design documents

 Option D is the correct statement about the Deployment Immediacy for VMM domains associated to EPGs when the APIC EPG Resolution Immediacy is set to “Immediate”. This means that the policy is pushed to the hardware as soon as the leaf switch is booted, regardless of whether there are any VMs in the EPG or not. This ensures that the policy is ready to be enforced as soon as a VM is created or moved into the EPG. References:

• Cisco APIC Basic Configuration Guide, Release 4.2(x) - Configuring VMM Domains [Cisco Application Policy Infrastructure Controller (APIC)], Configuring VMM Domains, Configuring the Deployment Immediacy for VMM Domains

 In a vPC (Virtual Port Channel) configuration, multicast traffic is handled based on the IGMP (Internet Group Management Protocol) and PIM (Protocol Independent Multicast) configurations. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the multicast routing table and the RPF (Reverse Path Forwarding) check.

Option B is correct because when multicast traffic with source address 10.10.10.10 targeting group 239.1.1.1 is received on Po10 Switch1, the switch will perform an RPF check and forward the traffic out of the interfaces that lead to the Rendezvous Point (RP) and the receivers. This ensures that the multicast traffic is efficiently distributed to all receivers that are part of the multicast group. The traffic would be forwarded out on Po1, which is typically connected to the RP, and Po20, which connects to other receivers in the network.

References := For more detailed information on multicast traffic forwarding in a vPC environment, please refer to Cisco’s official documentation on Implementing Cisco Data Center Core Technologies (DCCOR), specifically the sections discussing multicast routing and vPC configurations.

• Enable telemetry features on the Cisco Nexus 9000 Series Switch to collect and send real-time data.
• Configure a secure transport mechanism, such as gRPC with TLS encryption, to ensure that the monitoring data is transmitted securely.
• Set up a subscription-based monitoring service that can process the telemetry data and provide insights into the network health.

The contract between EPG Client and EPG Web allows TCP communication initiated by the client toward the webserver with TCP destination port 80. This means that the host in EPG Client can establish a connection to the webserver in EPG Web on TCP port 80. However, the contract does not allow the webserver to initiate a connection back to the host on the same port, which is typically used for HTTP traffic.

References: The explanation is based on the understanding of Cisco Application Centric Infrastructure (ACI) contracts, which are used to define the communication between EPGs (Endpoint Groups). For more detailed information, refer to the Cisco Data Center Core Technologies source book and the ACI documentation available on Cisco’s official website.

The correct option to associate a UCS B-Series server with a specific service profile when it becomes available is B. server. In Cisco UCS Manager, associating a service profile with a server can be done directly by selecting the server from the list of available hardware. This direct association ensures that when the server becomes available, it will be associated with the specified service profile, which contains the settings and policies for the server’s operation within the UCS environment.

 To establish adjacency to the remote peer by using multicast, the engineer needs to configure the otv data-group command with a multicast address range that is unique for each site. This command specifies the multicast group that is used to send and receive OTV data traffic. To enable OTV advertisements for VLAN 100 to the other site, the engineer needs to configure the otv extend-vlan command with the VLAN number. This command specifies which VLANs are extended across the overlay network. References:

To meet the deployment requirements for implementing VSANs on a Cisco MDS 9000 Series Switch, the correct steps are to create VSAN 10 in the VSAN database and bind it to the interface fc1/1. This assigns the host on port fc1/1 to VSAN 10. Additionally, enabling VSAN trunking on the Inter-Switch Link (ISL) and allowing VSAN 10 on the ISL ensures that the port channel 10 can pass multiple VSANs, including VSAN 10. This configuration allows for the segregation of traffic and maintains the isolation of different VSANs while still permitting communication across the shared physical infrastructure12.

FCoE (Fibre Channel over Ethernet) is a technology that allows Fibre Channel traffic to be encapsulated and transported over Ethernet networks. FCoE requires the use of FCFs (Fibre Channel Forwarders), which are devices that act as bridges between the FCoE and Fibre Channel domains. FCFs can be configured with a priority value that determines their preference for connecting to CNAs (Converged Network Adapters), which are devices that support both Ethernet and Fibre Channel protocols. The priority value ranges from 0 to 1024, with 0 being the lowest and 1024 being the highest. To configure an MDS switch as the best switch to connect by the CNAs in the fabric, the fcoe fcf-priority 1024 command should be applied. This gives the switch the highest priority and makes it the most preferred FCF for the CNAs.

 To ensure that vPC and non-vPC switches receive the same STP bridge ID from the upstream vPC switch peers, the engineer must implement the peer-switch feature on the vPC domain. The peer-switch feature allows the two vPC peer switches to act as a single logical switch for STP purposes, and to use the same bridge ID and priority. This way, the downstream switches will see the vPC peer switches as a single STP root, and will not have any STP loops or inconsistencies. The peer-switch feature also improves the convergence time and reduces the number of STP instances required in the network. References :=

When using VMware vMotion to migrate a Cisco WSA virtual appliance from one physical host to another, it is essential that both physical hosts have access to the same network configurations. This includes the same defined networks to which the interfaces on the virtual appliance are mapped. This requirement ensures that the virtual appliance retains its network connectivity and continues to function correctly after the migration1.

References := For more information on the requirements and process of migrating a Cisco WSA virtual appliance using VMware vMotion, you can refer to the Cisco Secure Email and Web Virtual Appliance Installation Guide1.

Option C is the correct configuration that is expected to be saved by using a logical configuration backup. A logical configuration backup includes the service profiles, service profile templates, policies, pools, and logical LAN and SAN connectivity configuration. It does not include the systems, roles, or servers configuration, which are part of the full state or all configuration backups. References:

The ACI REST API is a programmatic interface that uses REST architecture to interact with the management information tree (MIT) of the Cisco Application Policy Infrastructure Controller (APIC). The API requires authentication for users to access and manipulate the objects in the MIT. The authentication is based on username and password credentials, and the API provides several methods to manage the session authentication. Two of these methods are:

• POST to aaaLogin. This method logs in a user and opens a session. The message body contains an aaa:User object with the name and password attributes, and the response contains a session token and cookie. The session token and cookie are required for subsequent requests to the API, and they have a limited validity period that can be refreshed.
• DELETE to aaaLogout. This method logs out a user and closes a session. The message body contains an aaa:User object with the name attribute, and the response contains a status code indicating the success or failure of the operation. The session token and cookie are invalidated and cannot be used for further requests to the API.

References := The information is based on the Cisco APIC REST API Configuration Guide, which explains the usage and features of the ACI REST API, including the authentication methods89.

EIGRP authentication is used to prevent unauthorized devices from forming neighbor relationships. The correct CLI commands to establish EIGRP neighborship with authentication on Cisco Nexus switches involve configuring the interface with EIGRP, setting the EIGRP autonomous system number, and specifying the authentication key and key-chain. The commands in Option A are consistent with these requirements, hence it is the verified answer.

References: = For further details, you can refer to the official Cisco documentation on EIGRP authentication and configuration for Nexus switches available on the Cisco website.

The new employee needs to add VLANs into an existing Cisco UCS Manager and configure NTP synchronization with date and time zone settings. Option B, Ext LAN Config (ext-lan-security), grants privileges to configure external LAN connectivity settings including VLANs. Option D, Service Profile Config (Is-config), allows for configuring service profiles including NTP synchronization settings. References:

 Option A is the correct configuration set to create an EEM script that saves a copy of the running configuration on bootflash and writes a message to syslog when a user saves the configuration to a Cisco Nexus switch. The EEM script uses the event manager applet command to define the applet name and the event that triggers the script. In this case, the event is the CLI pattern “copy running-config startup-config” which matches the command that a user would use to save the configuration. The action commands specify the commands that the script will execute when the event occurs. In this case, the script will copy the running configuration to bootflash, write a message to syslog, and exit. The other options have incorrect commands or syntax errors. For example, option B uses the wrong event keyword, option C uses the wrong action keyword, and option D uses the wrong file name. References:

The ‘best-effort’ command is used when implementing a configuration checkpoint on a Cisco Nexus 9000 Series Switch to ensure that the process skips any existing vPC configuration errors and completes even if there are other configuration errors. This command is suitable for scenarios where it’s critical to proceed with the checkpoint despite errors, allowing the engineer to create a rollback point and address issues without disrupting the entire process.

On a Cisco Nexus 7700 Series switch, secured MAC addresses can be removed by either manually deleting the address from the configuration or when the address ages out, which is determined by the age limit set for the interface. The other options do not apply to the deletion of secured MAC addresses.

The OPTIONS method is used in REST APIs to return the HTTP methods that the server supports for a specific URL. This can be useful for discovering what functionality a REST API endpoint supports.

Two capabilities of the Cisco Network Assurance Engine are that it validates that devices comply with network security policies and that it predicts the impact of changes to the network. The Cisco Network Assurance Engine is a software solution that uses mathematical modeling and verification techniques to continuously analyze the state and configuration of the data center network. It can validate that the network devices are compliant with the intended security policies, such as access control lists, firewall rules, and encryption standards. It can also predict the impact of planned or unplanned changes to the network, such as software upgrades, configuration changes, or device failures, and provide proactive recommendations to avoid or resolve issues. The Cisco Network Assurance Engine helps to ensure that the network is always operating as intended and aligned with the business objectives. References :=

Upgrading the EPLD on a Cisco Nexus switch is a disruptive process that requires the switch to reboot multiple times. Each EPLD device on the switch must be upgraded individually, and the switch must reboot to initialize the new EPLD version for each device. This process ensures that all hardware components are properly updated and can operate with the new firmware, but it does cause temporary disruptions to network traffic as each module reboots.

References: For more detailed information, please refer to the Cisco Nexus 9000 Series FPGA/EPLD Upgrade Release Notes, where it discusses the impact of EPLD upgrades and the necessity of multiple reboots during the process1. Additionally, the Cisco Nexus 9000 Series NX-OS Software Upgrade and Downgrade Guide provides guidelines on the upgrade process, including the disruptive nature of EPLD upgrades

 To allow Layer 2 connectivity between Host 1 in VLAN 100 located in DataCenter 1 and Host 2 in VLAN 200 located in DataCenter 2, the correct OTV VLAN mapping configuration is option C. This configuration involves mapping VLAN 100 to VLAN 200 across the OTV overlay so that hosts in these separate VLANs can communicate as if they were in the same Layer 2 domain. The VLAN mapping is achieved by configuring the OTV edge devices in both data centers to associate the VLANs with each other.

 To automate the provisioning of Cisco ACI objects using Terraform while ensuring that APIC counts the authentication login requests against the threshold to avoid a DOS attack, signature-based authentication should be used. This method involves obtaining an authentication token from Cisco APIC, which will use the token to authenticate. However, APIC counts these authentication requests and applies a threshold to prevent DOS attacks. After too many attempts, the user ID and password authentication method may fail as the threshold is exceeded. To circumvent this issue, signature-based authentication is recommended, where a signature is calculated using a private key and passed with the request. This signature is then used to authenticate the user without being counted against the threshold, thus avoiding the risk of exceeding it and failing authentication.

References: The information is based on the Terraform documentation provided by CiscoDevNet

To create an environment variable that can be used by several policies in the Embedded Event Manager, the engineer should use the command N9k2 (config)# event manager environment mailserver ‘’10.10.10.10’’. This command defines a global environment variable named mailserver with the value of 10.10.10.10, which represents the external email server. The environment variable can then be referenced by any policy that needs to use the email server in its actions, such as sending notifications or alerts. The environment variable can also be modified or deleted as needed. The other commands are incorrect because they either use the wrong mode, the wrong keyword, or the wrong syntax. References :=

 In a vPC (Virtual Port Channel) data center interconnect, both vPC peer devices must have the same system MAC address to ensure that remote switches perceive them as a single logical switch. Since the system MAC value on SW1 is 00:23:04:ee:be:20, the same value must be configured on SW3 to maintain consistency in the vPC domain and ensure seamless communication between the two data center fabrics connected through this vPC interconnect.

References: = The explanation can be inferred from Cisco’s official documentation and resources related to configuring and managing vPCs, ensuring that both peer devices in a vPC domain are configured with identical parameters, including the system MAC address.

The DHCP snooping feature acts as a firewall between untrusted hosts and trusted DHCP servers. It validates DHCP messages received from untrusted sources and filters out invalid messages. To implement this on a Cisco Nexus 7000 Series Switch for VLAN 10, you would enable DHCP snooping for that VLAN and then configure the specific interface connected to the legitimate DHCP servers to be trusted. This ensures that DHCP responses from the legitimate servers are allowed, while responses from any other servers are blocked.

 To meet the high-security standards, the engineer should configure port security and fabric binding on VSAN 50. Port security prevents unauthorized devices from logging into the fabric by automatically learning and securing the World Wide Port Names (WWPNs) of devices connected to the switch ports. Fabric binding allows only authorized switches to join the fabric by creating a list of switch WWNs that are permitted to join a specific VSAN.

 In a vPC (Virtual Port-Channel) environment, multicast traffic is expected to be replicated to the ports that have joined the multicast group and also across the peer link. This ensures that in case of a failure scenario, orphan ports, which are ports not part of the vPC and only connected to one of the vPC peer switches, still receive the multicast stream. Option C correctly describes this behavior, where the multicast traffic is replicated to the ports that joined a given multicast group and the peer link, and the multicast traffic stream flows over the peer link to ensure that orphan ports receive the multicast stream in failure scenarios12.

References: = For a more in-depth understanding of multicast traffic flow in a vPC environment, you can refer to Cisco’s official documentation on multicast forwarding in vPC based on the location of the source1, as well as community discussions and technical articles available on the Cisco Community website

Option A is the correct configuration to meet the requirements of configuring system logging on the MDS switch. The commands set the console logging level to 5, which corresponds to the severity level of “warning” and above, and set the exec-timeout to 300 seconds, which means that the users will be logged out of the console after 5 minutes of inactivity. The other options are either incorrect or incomplete for the task. References:

Applying a control plane service policy with a rate-limiting feature allows the engineer to match all ICMP traffic and set a threshold for it. Traffic that exceeds this threshold can be dropped, thus mitigating the risk of ICMP-based DoS attacks while allowing legitimate ICMP traffic to pass through. This method ensures that the current ICMP traffic is not affected as long as it does not exceed the configured rate limit12.

References := For detailed steps on configuring rate limits and control plane policing on Cisco Nexus 9000 Series Switches, you can refer to the Cisco Nexus 9000 Series NX-OS Security Configuration Guide12. This guide provides comprehensive information on securing your network infrastructure and protecting against various types of attacks, including DoS attacks. It also covers the configuration of security features like rate limits and control plane policies to ensure network stability and security

The correct command to configure the source IP address on switch1 for mirroring traffic to a packet sniffer located on switch2 is option B, “monitor erspan origin ip-address 209.165.200.225”. This command sets the origin IP address for the Encapsulated Remote SPAN (ERSPAN) session, which allows traffic from a source port on one switch to be monitored on a destination port on another switch across an IP network.

The configuration must ensure that the SPAN session captures traffic from the file server’s VSAN to the destination interface connected to the FC analyzer. The commands provided in the exhibit show the setup of a SPAN session with the destination interface as port-channel 2 and the source interface as VSAN 100, which is likely the VSAN associated with the file server.

References := For more detailed information and step-by-step guidance on configuring SPAN sessions on Cisco MDS 9000 Series Switches, you can refer to the official Cisco documentation on Implementing and Operating Cisco Data Center Core Technologies (DCCOR) available at Cisco’s training and certifications page and the Cisco Community knowledge base. These resources provide comprehensive insights into deploying, securing, operating, and maintaining Cisco data center infrastructure, including the Cisco MDS Switches.

 A hybrid Cisco HyperFlex storage configuration is the best option for a virtual environment that is not performance-sensitive, but requires high storage capacity and a low cost. A hybrid configuration consists of a mix of solid-state drives (SSDs) and hard disk drives (HDDs) in each node. The SSDs are used for caching and metadata, while the HDDs are used for data storage. This allows for a balance between performance and capacity, as well as a lower cost per gigabyte than an all-flash configuration. A hybrid configuration also provides data deduplication and compression features to optimize storage efficiency and reduce the storage footprint. A hybrid configuration is suitable for general-purpose workloads, such as virtual desktop infrastructure (VDI), databases, and file servers. References :=

To achieve the goal of creating a new user in the local user database on Cisco UCS Fabric Interconnect that can change the vNIC and vHBA profiles and the fan speed and power redundancy profile of UCS Manager, the engineer needs to assign two roles to the user: server-compute and server-profile. The server-compute role allows the user to configure and manage the compute resources, such as servers, service profiles, pools, and policies. The server-profile role allows the user to configure and manage the network resources, such as vNICs, vHBAs, VLANs, VSANs, and LAN and SAN connectivity policies. These two roles provide the user with the necessary permissions to change the configuration inside UCS Manager version 3.1, as required by the goal. References :=

The History Count setting in a user management system is used to prevent the reuse of old passwords. It specifies the number of unique new passwords that must be used before an old password can be reused. This helps enhance security by ensuring that passwords are not easily guessable and that users are not cycling through a small set of favorite passwords.

The ‘Full State’ backup type in Cisco UCS Manager is designed to capture a snapshot of the entire system, which includes all configuration settings, system logs, and the operating system. This comprehensive backup can be used to fully restore the system in the event of a disaster recovery scenario. The ‘Full State’ backup is the only option that provides a complete system snapshot, making it the ideal choice for disaster recovery purposes.

References: The information regarding backup types and their purposes can be found in the Cisco Data Center Core Technologies source book, specifically in the section discussing system maintenance and backups within the Cisco UCS Manager platform.

Option A is the correct command sequence to configure HTTPS secure management for Cisco UCS Manager using a key ring named kr2016 and a key size of 1024 bits. The other options have incorrect commands or syntax errors. For example, option B uses the wrong command to set the modulus size, option C uses the wrong command to create the key ring, and option D uses the wrong command to name the key ring. References:

To configure a SPAN session on a Cisco Nexus 5600 Series Switch that monitors ingress traffic on interface Ethernet 1/3 without impacting the traffic analyzer on Ethernet 1/5, you would typically use the monitor session command to create a new session, specify the source interface with the source keyword, and the destination interface with the destination keyword. Additionally, you would apply a rate limit to the session to adhere to the traffic budget of 1 Gbps.

To meet the requirements of securing HSRP communication and supporting more than 300 groups, the commands needed are hsrp version 2 which allows for a greater number of HSRP groups (0-4095) and authenticate md5 key-chain NHRP-KEYS which provides MD5 authentication to secure HSRP updates.

The command in question is likely to temporarily suspend the Protocol Independent Multicast (PIM) join messages. This action does not delete the PIM database or flush the Multicast Routing Information Base (MRIB), nor does it suspend multicast traffic forwarding. Instead, it interrupts the PIM join messages, which are used to build and maintain the multicast distribution tree.

References := For an in-depth explanation, one should refer to the Cisco Data Center Core Technologies study materials, which cover the PIM protocol and its behaviors in detail.

 A Cisco All-Flash HyperFlex solution requires two solid state drives (SSDs) for the local storage configuration of the operating system and persistent logging. The SSDs are used to store the hypervisor, the HyperFlex controller VM, and the system logs. The SSDs also provide high performance and reliability for the system operations. The SSDs are configured in a RAID 1 mirror mode, which provides redundancy and fault tolerance. The SSDs are separate from the data storage drives, which are also SSDs in an All-Flash HyperFlex solution. References :=

To facilitate communication between the APIC controller and an OpenStack OpFlex agent, it’s necessary to enable the Infra VLAN on the Attachable Access Entity Profile (AAEP). The AAEP is used in Cisco ACI to group interfaces that share common policies and extending the Infra VLAN to these interfaces allows the OpFlex agent, which is part of the Cisco Application Centric Infrastructure (ACI), to communicate with the APIC controller. This setup is crucial for the OpFlex agent to function correctly, as it relies on the Infra VLAN for communication with the APIC controller1.

The correct command to restore the running configuration on a Cisco Nexus 5000 Series Switch to an existing snapshot called “stable1” is found in Option C. The command rollback checkpoint stable1 best-effort running-config best-effort ensures that the restore procedure will proceed only if no errors occur, which aligns with the requirement stated in the question. The “best-effort” parameter is crucial as it indicates that the rollback should only proceed if it can be completed without any errors.

 To implement private VLANs for Cisco UCS 8-Series servers, the primary VLAN is already present, and the secondary VLAN needs to be added to both fabrics. The correct configuration set that accomplishes this task is Option C. This option includes the necessary commands to create the VLAN and set its sharing to secondary, which is required for the configuration of private VLANs in a Cisco UCS environment12.

References: = For detailed steps and configurations, refer to the Cisco documentation on private VLANs and UCS configuration12. It provides comprehensive guidance on setting up private VLANs in the Cisco UCS environment.

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

The network administrator role in Cisco UCS Manager is designed to allow configuration of network-related settings, which includes vHBAs, vNICs, and server port types. This role provides the necessary privileges to manage these components

When converting a Cisco MDS switch to support NPIV mode, it must be enabled globally on all VSANs (B). NPIV allows multiple virtual machines to share a single physical Fibre Channel port, which means that enabling it on all VSANs ensures that this functionality is available across the entire network.

 In a vPC (Virtual Port-Channel) configuration, multicast traffic is handled based on the vPC design and operational rules. When a host sends traffic to a multicast group, the vPC switches determine the forwarding path based on the source and the vPC domain configuration. If multicast traffic is received on a vPC member port, such as Po10 on Switch1, the traffic is typically forwarded out on all ports that are part of the same VLAN and have receivers interested in the multicast group, which includes Po1 and Po20 in this case. This ensures that the multicast traffic reaches all intended recipients across the vPC domain.

References: For a comprehensive understanding, the Cisco documentation on “Multicast forwarding in vPC based on location of the source” provides detailed scenarios and explanations on how multicast traffic is forwarded in a vPC environment1. Additionally, the “Cisco Nexus 9000 Series NX-OS Multicast Routing Configuration Guide” offers insights into the configuration and behavior of multicast routing on Nexus switches, which can be applied to understand the vPC behavior with multicast traffic

 To directly connect a Fibre Channel storage array to a Cisco UCS domain, configuring a new VSAN is essential as it creates a separate fabric to isolate the storage traffic. Additionally, creating a Storage Connection Policy is necessary to define how the UCS domain will communicate with the storage array, including zoning and VSAN membership.

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards. References: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

 In Cisco UCS Central, user privileges are managed through roles and locales. When a user moves departments, their access privileges need to be updated to reflect their new role. By creating a new locale for the Admin department and adding the user to this locale, the user’s access privileges are updated to include the Admin department’s data and applications. The old Finance locale should be deleted, or the user should be removed from it, to revoke the previous access privileges1.

To monitor ingress traffic from SW1 and SW2 port-channel interfaces from SW3, the engineer must implement a configuration that specifies the source interfaces for monitoring and the destination interface where the monitored traffic will be sent. The correct configuration is found in Option D, which includes the commands to create a monitor session, specify the source interfaces as port-channel 1 and port-channel 2 with the ‘rx’ option to indicate ingress traffic, and set the destination interface to Ethernet 1/4 where the traffic can be analyzed. This setup uses a Switched Port Analyzer (SPAN) or Remote SPAN (RSPAN) to capture and forward the traffic for monitoring purposes.

References := The configuration aligns with Cisco’s best practices for setting up SPAN or RSPAN sessions for traffic monitoring as detailed in the Implementing and Operating Cisco Data Center Core Technologies (DCCOR) course materials and Cisco’s official documentation

 The preserve identities feature is not included in the logical configuration backup operation type. This type of backup includes the configuration settings that are logically grouped, such as service profiles, policies, and pools, but does not include the unique identifiers or configurations that are specific to a particular system or setup, which are preserved in a full state or system configuration backup.
