Implementing Cisco Application Centric Infrastructure (DCACI) — Question 190

An engineer must connect a new host to port 1/1 on Leaf 101. A Cisco ACI fabric has an MCP policy configured but experiences excessive Layer 2 loops. The engineer wants the Cisco ACI fabric to detect and prevent Layer 2 loops in the fabric. Which set of actions accomplishes these goals?

Answer options

• A. Enable MCP locally. Associate the MCP policy with an interface policy group.
• B. Enable MCP locally. Associate the MCP policy with an interface profile.
• C. Enable MCP globally. Associate the MCP policy with an interface selector.
• D. Enable MCP globally. Associate the MCP policy with an interface policy group.

Correct answer: D

Explanation

The correct answer is D because enabling MCP globally allows it to apply across the entire fabric, and associating it with an interface policy group ensures that all ports within that group are protected against Layer 2 loops. Options A and B only enable MCP locally, which would not provide the necessary coverage for the entire fabric. Option C incorrectly associates MCP with an interface selector, which does not fulfill the requirements for preventing Layer 2 loops.
