Implementing Cisco Application Centric Infrastructure (DCACI) — Question 234

An engineer must configure a Cisco ACI bridge domain to prevent flooding from unknown unicast frames. Which action must be configured in Cisco ACI to accomplish this goal?

Answer options

• A. Set the bridge domain option to Flood in Encapsulation.
• B. Configure Clear Remote MAC Entries in the bridge domain mode.
• C. Set Disable Remote EP Learn in the Fabric Wide Setting Policy.
• D. Configure the bridge domain to operate in optimized mode.

Correct answer: D

Explanation

The correct choice is D, as operating the bridge domain in optimized mode prevents flooding of unknown unicast frames by managing how MAC addresses are learned and handled. Options A, B, and C do not specifically address the prevention of flooding from unknown unicast frames, making them ineffective for this requirement.
