• Question 35:

  What is the advantage of implementing an active-active firewall cluster that is stretched across separate pods when anycast services are configured?

  A. A different MAC/IP combination can be configured for the firewall in each pod.

  B. The local pod anycast node is preferred by the local spines.

  C. A cluster can be deployed in transparent mode across pods.

  D. Local traffic in a pod is load-balanced between the clustered firewalls.

  Correct Answer: A

• Question 36:

  

  Refer to the exhibit. A network engineer configures a Layer 4 to Layer 7 device for an outside routed firewall that is connected to POD-1 inside a Cisco ACI fabric that consists of two pods.

  A. GoThrough

  B. L1

  C. GoTo

  D. L2

  Correct Answer: D

• Question 37:

  A. Enable Endpoint Dataplane Learning

  B. Disable service node Health Tracking

  C. Enable Pod ID Aware Redirection

  D. Disable Resilient Hashing

  Correct Answer: B

• Question 38:

  A. Select the Route Reflector field in Pod Peering

  B. Enable the DSCP class-cos translation policy for Layer 3 traffic

  C. Configure POD 2 Data Plane TEP under the Pod Connection Profile

  D. Add the IPN subnet under the Fabric External Routing Profile

  Correct Answer: D

• Question 40:

  Which firewall connection allows for the integration of service nodes in transparent mode with a Cisco ACI Multi-Pod setup?

  A. active-standby mode across pods

  B. active-active mode per pods for communication between internal endpoints
