Implementing Cisco ACI Advanced (DCACIA) — Question 20

In a Cisco ACI Multi-Site fabric, the Inter-Site BUM Traffic Allow option is enabled in a specific stretched bridge domain. What is used to forward BUM traffic to all endpoints in the same broadcast domain?

Answer options

• A. ingress replication on the spines in the source site
• B. egress replication on the source leaf switches
• C. egress replication on the destination leaf switches
• D. ingress replication on the spines in the destination site

Correct answer: D

Explanation

The correct answer is D because ingress replication on the spines in the destination site is responsible for distributing BUM traffic to all endpoints in the broadcast domain. Options A, B, and C do not correctly describe the role of ingress replication in the context of BUM traffic forwarding in a Multi-Site fabric.
