Implementing Cisco Application Centric Infrastructure (DCACI) — Question 304

A Cisco ACI fabric must be integrated with a VMware vSphere environment. One of the ESXi hosts is still disconnected from the Distributed Virtual Switch (DVS) and the VMM domain. Two EPGs have already been created and associated with the VMM domain. An engineer must prepare the ACI configuration such that:
• EPG contracts must be sent to ACI leaf switches before a hypervisor is attached to the DVS.
• EPG contracts must be pushed to leaf hardware as soon as the policy is downloaded into the leaf software.

Which EPG configuration must be used to meet these requirements?

Answer options

• A. Resolution immediacy: Pre-provision Deployment immediacy: On-Demand
• B. Resolution immediacy: Pre-provision Deployment immediacy: Immediate
• C. Resolution immediacy: On-Demand - Deployment immediacy: On-Demand
• D. Resolution immediacy: On-Demand - Deployment immediacy: Immediate

Correct answer: B

Explanation

The correct answer is B because it ensures that EPG contracts are pre-provisioned before the hypervisor connects to the DVS, and they are deployed immediately to the leaf hardware once the policy is downloaded. Option A delays deployment until on-demand, which does not meet the immediate requirement, while options C and D do not fulfill the pre-provisioning requirement for EPG contracts.
