Implementing Cisco Application Centric Infrastructure (DCACI) — Question 248

How does Cisco ACI detect the IP address of a silent host that moved from one location to another without notifying a Cisco ACI leaf?

Answer options

• A. Silent hosts are detected by the ACI fabric.
• B. Endpoint announce messages are sent to COOP.
• C. ARP requests are flooded in the bridge domain.
• D. Bounce entries are installed on the leaf switch.

Correct answer: C

Explanation

Cisco ACI utilizes ARP requests broadcasted within the bridge domain to discover the IP address of silent hosts that have relocated. This process allows the ACI fabric to learn about the new location of the host without prior notification. The other options do not accurately describe how silent hosts are detected in this scenario.
