Implementing Cisco Application Centric Infrastructure (DCACI) — Question 73

An engineer deploys a two-pod Cisco ACI Multi-Pod environment. Why should no more than two Cisco APIC controllers be deployed in the same pod?

Answer options

• A. to enable equal capacity to scale in each pod
• B. to avoid losing all replicas of a shard if a pod fails
• C. to avoid hair-pinning traffic that is destined for the primary APIC controller between pods
• D. to ensure that all nodes in all pods have local access to a controller

Correct answer: B

Explanation

The correct answer is B, as having more than two APIC controllers in a single pod could result in losing all replicas if that pod encounters a failure. Options A, C, and D do not address the critical issue of shard replication and pod failures, making them less relevant to the question's focus on redundancy and data integrity.
