Implementing Cisco Application Centric Infrastructure (DCACI) — Question 87

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

Answer options

• A. Ingress replication is used on the spines to forward broadcast frames in the IPN infrastructure.
• B. Within a pod, the ingress leaf switch floods the broadcast frame on all fabric ports.
• C. Broadcast frames are forwarded inside the pod and across the IPN using the multicast address that is associated to the bridge domain.
• D. For the specific bridge domain, all spines forward the broadcast frames to IPN routers.

Correct answer: C

Explanation

The correct answer is C because it accurately describes the process of forwarding broadcast frames using the multicast address for the bridge domain. Option A is incorrect as ingress replication is not specifically mentioned in this context, B is wrong because it only addresses in-pod flooding, and D does not reflect the use of multicast addresses for forwarding across the IPN.
