Implementing Cisco Application Centric Infrastructure (DCACI) — Question 231

How does Cisco ACI manage the old endpoint information on the original leaf switch after an endpoint moves between two Cisco ACI leaf switches?

Answer options

• A. A bounce entry is created by COOP communication instead of data plane learning.
• B. A remote endpoint is created to represent the endpoint on another leaf.
• C. Cisco APIC deletes an endpoint after receiving GARP packets from the new leaf.
• D. The spine switch pushes all endpoint database entries to all leaf switches.

Correct answer: A

Explanation

The correct answer is A because when an endpoint moves, COOP communication creates a bounce entry to retain the old endpoint information instead of relying on data plane learning. Options B and C are incorrect as they suggest different mechanisms that do not apply to the management of old endpoint information in this scenario. Option D is also incorrect as it implies a broader distribution of endpoint data that does not occur in this context.
