Implementing Cisco Application Centric Infrastructure (DCACI) — Question 256

A Cisco ACI fabric must detect all silent endpoints for the Layer 3 bridge domain. Which actions accomplish this goal?

Answer options

• A. Enable Unicast Routing. Disable ARP Flooding.
• B. Disable Unicast Routing. Enable L2 Unknown Unicast Hardware Proxy.
• C. Enable Unicast Routing. Enable ARP Flooding.
• D. Disable Unicast Routing. Enable L2 Unknown Unicast Flood.

Correct answer: D

Explanation

The correct answer is D because disabling Unicast Routing allows the ACI fabric to flood unknown unicast traffic, which helps in detecting silent endpoints. The other options either enable Unicast Routing or utilize proxies that do not facilitate the necessary flooding to discover silent endpoints.
