Implementing Cisco ACI Advanced (DCACIA) — Question 96

An engineer is deploying a Cisco ACI fabric and discovers that the traffic to certain endpoints is dropped. The originating bridge domain is configured with hardware proxy.
Which action prevents this problem?

Answer options

• A. Set the L2 Unknown Unicast option to Flood for Layer 2 switched traffic.
• B. Set the L2 Unknown Unicast option to Hardware-Proxy for Layer 2 switched traffic.
• C. Enable the ARP Flooding option under the bridge domain for Layer 3 routed traffic.
• D. Disable the ARP Flooding option under the bridge domain for Layer 3 routed traffic.

Correct answer: B

Explanation

The correct answer is B because setting the L2 Unknown Unicast option to Hardware-Proxy allows the network to handle unknown unicast traffic appropriately by using the proxy mechanism. Options A and C do not address the issue effectively, while option D could potentially worsen the problem by limiting necessary ARP responses.
