Implementing Cisco Application Centric Infrastructure (DCACI) — Question 175

What is the result of selecting the On Demand attribute in the Deploy Immediacy feature during VMM domain association to an EPG?

Answer options

• A. The EPG policy is programmed in the hardware policy CAM as soon as the policy is downloaded in the leaf software.
• B. The EPG policy is downloaded to the leaf when a hypervisor is attached to a DVS, and CDP or LLDP adjacency is formed.
• C. The EPG policy is downloaded to the leaf when a hypervisor is connected, and a VM is placed in a port group.
• D. The EPG policy is programmed in the hardware policy CAM only when the first packet is received through the data path.

Correct answer: D

Explanation

The correct answer is D because selecting the On Demand attribute means that the EPG policy is only programmed into the hardware policy CAM when the first packet is received, ensuring efficient resource usage. Options A, B, and C describe scenarios where the policy is applied or downloaded before any data traffic, which does not align with the On Demand behavior.
