Implementing Cisco ACI Advanced (DCACIA) — Question 11

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

Answer 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

Correct answer: A

Explanation

The correct answer is A because in Cisco ACI Multi-Pod, when ARP flooding is enabled, all spines are responsible for forwarding broadcast frames to the IPN routers for a specific bridge domain. Option B is incorrect as it describes multicast forwarding rather than broadcast. Option C is not accurate for Multi-Pod configurations, and option D incorrectly states the mechanism used for forwarding broadcast frames in this context.
