Implementing Cisco Application Centric Infrastructure - Advanced (DCACIA) Questions and Answers

Question 1

A customer is deploying a new application across two ACI pods that is sensitive to latency and jitter. The application sets the DSCP values of packets to AF31 and CS6, respectively. Which configuration changes must be made on the APIC to support the new application and prevent packets from being delayed or dropped between pods?

Options:

A.

disable DSCP translation policy

B.

align the ACI QoS levels and IPN QoS policies

C.

disable DSCP mapping on the IPN devices

D.

align the custom QoS policy on the EPG site in the customer tenant

Question 2

Refer to the exhibits.

Which subject must be configured for the All_noSSH contract to allow all IP traffic except SSH between the two EPGs?

Options:

A.

Option A

B.

Option B

C.

Option C

D.

Option D

Question 3

An engineer must allow routes learned from one L3Out to be advertised out another L3Out. The engineer does not have an explicit list of all the routes that must be advertised out, however, they know that they are all part of the 10.16.0.0/16 CIDR block. Which attributes must be selected under Ext-EPG to allow the necessary routes to be advertised out?

Options:

A.

Enable Export Route Control Subnet and enable Aggregate Export

B.

Disable Shared Route Control Subnet and enable Aggregate Shared Routes

C.

Enable Export Route Control Subnet and disable Aggregate Shared Routes

D.

Enable Export Route Control Subnet and enable Shared Route Control Subnet

Question 4

An engineer configures a new Cisco ACI Multi-Pod and must set up the link between the spine and the IPN device. Which three actions should be taken to accomplish this goal? (Choose three.)

Options:

A.

Enable MP-BGP routing

B.

Enable BIDIR-PIM protocol

C.

Enable PIM-SM protocol

D.

Enable OSPF routing

E.

Enable IS-IS routing

F.

Enable DHCP relay

Question 5

How is multicast traffic managed in a Cisco ACI fabric?

Options:

A.

FTag trees are rooted at the spine nodes. Cisco APIC determines the roots.

B.

FTag trees are rooted at the leaf nodes. Cisco APIC determines the roots.

C.

FTag trees are rooted at the leaf nodes. The roots must be configured manually.

D.

FTag trees are rooted at the spine nodes. The roots must be configured manually.

Question 6

Refer to the exhibit.

An engineer is configuring a vSwitch policy in the existing Cisco ACI fabric. The requirement is for the Cisco ACI leaf to learn individual MAC addresses from the same physical port. Which vSwitch policy configuration mode must be enabled to meet this requirement?

Options:

A.

MAC pinning

B.

MAC binding

C.

LACP passive

D.

LACP active

Question 7

An engineer deployed a Cisco ACI fabric and noticed that the fabric learns endpoints from subnets that are not configured on a bridge domain. To meet strict security requirements, the engineer must prevent this behavior. Which action must be taken to prevent this behavior?

Options:

A.

Activate Enable Data Plane Endpoint Learning

B.

Implement Pervasive Gateway

C.

Configure Static Binding

D.

Enable Enforce Subnet Check

Question 8

What are two characteristics of network-centric design in Cisco ACI? (Choose two.)

Options:

A.

There is open communication between EPGs

B.

EPGs are used for microsegmentation

C.

EPGs are different security zones

D.

Applications define the network requirements

E.

A bridge domain has one subnet and one EPG

Question 9

How is broadcast forwarded in Cisco ACI Multi-Pod after ARP flooding is enabled?

Options:

A.

For the specific bridge domain, all spines forward the broadcast frames to IPN routers

B.

Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain

C.

Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports

D.

Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure

Question 10

An engineer configures a new Cisco ACI Multi-Site Orchestrator node to join an MSO cluster. Which two components are necessary to ensure that the new node has IP connectivity in this configuration? (Choose two.)

Options:

A.

Cisco ACI spine interfaces that are connected to ISN

B.

Cisco APICs over the OOB management network

C.

existing Cisco ACI Multi-Site Orchestrator node

D.

management IP of ESXi hosts where the controllers are deployed

E.

OOB interface of ISN

Question 11

An engineer is implementing the Cisco ACI fabric but is experiencing loops detected from endpoints. When the issue was investigated, it was discovered that the packets are received with the same source IP address but from different leaf switch ports. The engineer must prevent the issue from happening in the future and make sure that the port is brought back up if it was disabled due to the loop discovered. Which set of actions must be taken to meet these requirements?

Options:

A.

Enable the enforce endpoint check and set the Rouge EP detection interval

B.

Enable the rogue endpoint and set the Error Disabled Recovery Policy

C.

Enable the remote endpoint limit and set the Interface override

D.

Enable reverse path forwarding and set the Hold Interval
