What two best describe self-healing functionality on vEdges?
Self-healing functionality on vEdges refers to the ability of the vEdge routers to recover from failures or errors that affect their connectivity or performance. Two examples of self-healing functionality on vEdges are:
What is the default interval for BFD packets?
The default interval for BFD packets is 1 second. BFD uses Hello packets to detect the liveness and faults on a connection. BFD Hello Interval packet is sent at the default interval of 1000 milliseconds on all connections1. This command can be used to change the hello interval for a transport color. The interval for transmitting and receiving BFD packets can also be configured on the interface level or the BFD session level, depending on the device and the protocol234. The BFD detection time is calculated as the product of the local detection multiplier and the agreed remote transmission interval. The lower the BFD detection time, the faster the BFD session can detect a fault. However, a lower BFD detection time also consumes more system resources and bandwidth. Therefore, the BFD detection time should be configured according to the network situation and performance requirements. References:
Which Cisco SD WAN component provides a secure data plane with remote vEdge routers?
vEdge is the Cisco SD WAN component that provides a secure data plane with remote vEdge routers. vEdge routers are the devices that sit at the edge of the SD WAN fabric and connect to the WAN transports, such as MPLS, Internet, or LTE. vEdge routers establish secure IPsec tunnels with other vEdge routers in the fabric and exchange routing and policy information with the vSmart controller. vEdge routers also perform application-aware routing, QoS, and security functions on the data plane traffic. vEdge routers can be physical or virtual devices and can be deployed in branch, campus, data center, or cloud environments1.
The other options, vBond, vSmart, and vManage, are not the components that provide a secure data plane with remote vEdge routers. vBond is the orchestrator that performs the initial authentication and authorization of vEdge routers and assigns them to a vSmart controller. vSmart is the controller that distributes the control and data policies and the network topology information to the vEdge routers. vManage is the management platform that provides centralized configuration, monitoring, and troubleshooting of the SD WAN fabric1.

Which three services must be enabled under the ISE Admin settings to successfully integrateISE, when integrating ISE with DNA-C? (Choose three.)
Cisco ISE configuration capabilities include the following features:
1: [Cisco Identity Services Engine Administrator Guide, Release 3.3 - ISE Deployment Assistant [Cisco Identity Services Engine]] : 2: [Cisco Identity Services Engine Administrator Guide, Release 3.3 - Wireless Setup Wizard [Cisco Identity Services Engine]] : 3: [Cisco Identity Services Engine Administrator Guide, Release 3.3 - Visibility Wizard [Cisco Identity Services Engine]] : : [Cisco Identity Services Engine Administrator Guide, Release 3.3 - ISE Wizards and Pre-Canned Configurations [Cisco Identity Services Engine]]
Which three methods three technologies and deployed to gather data and provide insight? (Choose three.)
Syslog, FNF (Flexible NetFlow), and SNMP (Simple Network Management Protocol) are three technologies that can be deployed to gather data and provide insight into the network performance, health, and behavior. Syslog is a standard protocol for logging messages from network devices, such as routers, switches, firewalls, and servers. Syslog messages can be sent to a centralized server for analysis, correlation, and alerting. FNF is a Cisco technology that captures and exports information about network flows, such as source and destination IP addresses, ports, protocols, bytes, packets, and timestamps. FNF can be used to monitor network traffic patterns, identify anomalies, and optimize network resources. SNMP is a protocol that allows network devices to communicate with management systems, such as Cisco DNA Center. SNMP can be used to collect statistics, configuration, and status information from network devices, as well as to send commands and notifications. SNMP can help network administrators to troubleshoot, configure, and manage their network devices remotely.

Which two options are used as part of an ISE POV? (Choose two.)
An ISE PoV (Proof of Value) is a service that demonstrates the value of Cisco Identity Services Engine (ISE) to potential customers. It consists of two components: a virtual machine (VM) and a license. The VM is a pre-configured ISE environment that can be deployed on any cloud platform, such as Cisco dCloud1. The license is a one-time payment that grants access to the ISE features and capabilities for three years2.
The two options that are used as part of an ISE PoV are A and E. Option A refers to the VM, which is the core component of the ISE PoV. Option E refers to the POV Kit, which is a bundle that includes the VM, the license, and some additional resources, such as documentation, videos, and webinars2. Option B, C, and D are not used as part of an ISE PoV.

Where does the Cisco V-Edge Router perform QOS traffic classification?
The Cisco V-Edge Router performs QoS traffic classification on the ingress interface, before the traffic enters the VPN. The classification is based on the match criteria specified in the access lists, which can include the source and destination IP addresses, ports, protocols, DSCP values, and application-aware NBAR attributes. The classification results in assigning a forwarding class and a QoS group to each packet. The forwarding class determines the output queue and the scheduling policy for the packet on the egress interface. The QoS group is an internal label that can be used to remark the DSCP value of the packet or to match the packet in another access list for further processing. References:
Which three wireless product families are supported in the current DNA-C 1.1 release? (Choose three.)
According to the Cisco DNA Center Compatibility Matrix1, the current DNA-C 1.1 release supports the following wireless product families:
The other wireless product families, such as AP 1260 and WLC 5508, are not supported in the current DNA-C 1.1 release.
How many vEdge router security zones (VPN’s) can be configured?
Which two factors are used in calculating the Cisco SD WAN-1yr, 3yr, or 5yr subscription cost? (Choose two.)
The Cisco SD-WAN subscription cost is based on two factors: the features and the service bandwidth. The features are determined by the subscription tier, which can be Cisco DNA Essentials, Cisco DNA Advantage, or Cisco DNA Premier. Each tier offers different levels of functionality, security, and analytics for the SD-WAN solution. The service bandwidth is the aggregated WAN bandwidth across all the edge devices in the SD-WAN fabric. The subscription cost is calculated as the product of the feature price per Mbps and the service bandwidth. For example, if the feature price per Mbps for Cisco DNA Advantage is $2 and the service bandwidth is 100 Mbps, the subscription cost for one year is $2 x 100 x 12 = $240012
The other factors, such as the hypervisor platform, the security, and the routing protocol, are not used in calculating the Cisco SD-WAN subscription cost. The hypervisor platform is the virtualization environment where the SD-WAN edge software can run, such as VMware ESXi, KVM, or Microsoft Hyper-V. The security is the protection of the SD-WAN network from threats and attacks, which can be enhanced by integrating with complementary products and applications, such as Cisco Umbrella, Cisco SIG Essentials, or Cisco Secure Malware Analytics. The routing protocol is the method of exchanging routing information between the SD-WAN edge devices and the external networks, such as BGP, OSPF, or EIGRP. These factors are not directly related to the subscription cost, but rather to the deployment options, the security requirements, and the network design of the SD-WAN solution34
