Implementing Cisco Application Centric Infrastructure (DCACI) — Question 130

An engineer is implementing a Cisco ACI environment that consists of more than 20 servers. Two of the servers support only Cisco Discovery Protocol with no other link discovery protocol. The engineer wants the servers to be discovered automatically by the Cisco ACI fabric when connected. Which action must be taken to meet this requirement?

Answer options

• A. Create an override policy that enables Cisco Discovery Protocol after LLDP is enabled in the default policy group.
• B. Configure a higher order interface policy that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
• C. Configure a lower order policy group that enables Cisco Discovery Protocol for the interface on the desired leaf switch.
• D. Create an interface profile for the interface that disables LLDP on the desired switch that is referenced by the interface policy group.

Correct answer: B

Explanation

The correct answer is B because configuring a higher order interface policy specifically enables Cisco Discovery Protocol for the desired interface, ensuring that the servers can be discovered automatically. Options A and D do not directly address the need for Cisco Discovery Protocol to be active for the servers, and option C may not have the required priority in the policy hierarchy to take effect.
