Implementing Cisco ACI Advanced (DCACIA) — Question 56

An organization expands a Cisco ACI Multi-Pod from two to six pods and must ensure that the control plane scales. What should be configured in the IPN to ensure that BUM traffic is forwarded efficiently across the IPN?

Answer options

• A. spine headend replication
• B. BIDIR-PIM
• C. MP-BGP
• D. MSDP

Correct answer: B

Explanation

BIDIR-PIM is designed to efficiently distribute BUM traffic across multiple pods by allowing for shared tree and shortest path tree routing. The other options, while related to multicast and routing, do not specifically address the efficient handling of BUM traffic within the context of Cisco ACI Multi-Pod scaling.
