Implementing Cisco Application Centric Infrastructure (DCACI) — Question 184

Which feature should be disabled on a bridge domain when a default gateway for endpoints is on an external device instead of a Cisco ACI bridge domain SVI?

Answer options

• A. unknown unicast flooding
• B. ARP flooding
• C. unicast routing
• D. proxy ARP

Correct answer: C

Explanation

The correct answer is C, unicast routing, because when the default gateway is external, unicast routing must be disabled to prevent the bridge domain from attempting to route packets instead of relying on the external device. The other options, such as unknown unicast flooding, ARP flooding, and proxy ARP, are not directly related to the configuration of a default gateway and do not need to be disabled in this scenario.
