Exam 300-620 topic 1 question 84 discussion

Actual exam question from Cisco's 300-620

Question #: 84
Topic #: 1

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?

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.

Selected Answer: B

To enable automatic discovery of the two servers that support only Cisco Discovery Protocol (CDP) by the Cisco ACI fabric, the engineer must: Enable CDP on the ACI leaf switch interfaces where these servers will be connected. By enabling CDP on the relevant leaf switch interfaces, the ACI fabric will be able to discover and gather information about the connected servers using CDP. This action ensures that even though these servers do not support LLDP (Link Layer Discovery Protocol), which is the default discovery protocol used in ACI, they can still be automatically discovered and integrated into the fabric.

A leaf interface override policy allows interfaces that have interface policy group assignments to apply an alternate interface policy group

Selected Answer: B

In Cisco ACI, interface policies determine the behavior of physical interfaces, including protocols like Cisco Discovery Protocol (CDP) and Link Layer Discovery Protocol (LLDP). Since LLDP is enabled by default in ACI, configuring a higher-order interface policy that explicitly enables CDP will override the default behavior, ensuring that CDP is used on the interfaces connected to the servers that only support CDP.
