Implementing Cisco Application Centric Infrastructure (DCACI) — Question 212

An endpoint called EP1 is connected to Cisco ACI compute leaf1. The engineer must replace EP1 with EP2 on the same leaf switch. Which set of actions forces all remote leaves to delete EP1 before timer expiration?

Answer options

• A. Set L2 Unknown Unicast to Hardware proxy. Select Clear remote MAC entries.
• B. Set L2 Unknown Unicast to Flood. Select Clear remote MAC entries.
• C. Set L2 Unknown Unicast to Hardware Proxy. Select Clear remote IP entries.
• D. Set L2 Unknown Unicast to Flood. Select Clear remote IP entries.

Correct answer: B

Explanation

The correct answer is B because setting L2 Unknown Unicast to Flood ensures that traffic is sent to all ports, prompting remote leaves to clear the MAC entries for EP1. The other options either do not utilize flooding or attempt to clear IP entries, which is not relevant to the immediate removal of MAC addresses.
