Implementing Cisco Application Centric Infrastructure (DCACI) — Question 90

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

Correct answer: A

Explanation

The correct answer is A because ingress replication on the spines in the source site is responsible for distributing BUM traffic to all endpoints in the stretched bridge domain. The other options are incorrect as they either refer to egress replication, which does not handle BUM traffic in this context, or involve the destination site which is not applicable when traffic originates from the source site.
