Question No. 1

Refer to the exhibit.

An engineer is deploying a Cisco ACI Multi-Pod with an independent active/active Layer 3 firewall cluster across the pods. Which task must the engineer perform to prevent the creation of duplicate IP/MAC entries across the pods?

Show Answer Hide Answer
Correct Answer: C

In a Cisco ACI Multi-Pod deployment, configuring the subnet as shared is crucial to prevent duplicate IP/MAC entries across pods. This allows endpoints in different pods to be part of the same subnet without causing IP/MAC duplication issues, ensuring policy enforcement by the firewall cluster.Reference:= ( Implementing Cisco Application Centric Infrastructure Official Cert Guide )

Question No. 4

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

Show Answer Hide Answer
Correct Answer: B

Implementing an active-active firewall cluster stretched across separate pods with anycast services configured offers several advantages, one of which is that it allows for optimized routing within the Cisco ACI fabric. When anycast services are used, each pod can have its own anycast node (firewall instance), and due to routing preferences set within ACI's spine switches, they will prefer their local pod's anycast node for routing decisions. This preference enhances efficiency by reducing cross-pod traffic and improving response times since local spines direct traffic to their respective local pod's anycast nodes.Reference: Implementing Cisco Application Centric Infrastructure Official Cert Guide


Question No. 5

An engineer designs a Cisco ACI Multi-Pod solution that requires a pair of active-standby firewalls in different pods for external connectivity. How should the firewalls be implemented?

Show Answer Hide Answer
Correct Answer: B

In a Cisco ACI Multi-Pod design, having separate Layer 3 Out (L3Out) connections for each pod is recommended when implementing active-standby firewalls in different pods. This setup allows for independent routing and failover mechanisms, ensuring that each pod can maintain external connectivity even if one firewall fails.
