Question
A Cisco ACI fabric must be integrated with the VMware environment. An ESXi host is not attached to the Distributed Virtual Switch (DVS). Two EPGs were created and associated with the VMM domain. An engineer was asked to configure the ACI environment to meet these requirements:
- The EPG contract is pushed to ACI leafs after the ESXi host is
attached to the DVS.
- The EPG contract is pushed to the TCAMs only when two EPGs start to
communicate. Which immediacy settings accomplish these goals?

Explanation
Resolution immediacy On-Demand ensures that ACI programs EPG-to-EPG contract entries in TCAM only when the two EPGs actually communicate, meeting the requirement of pushing contracts to hardware only when needed. Deployment immediacy On-Demand ensures that the policy is pushed to the leaf switches only after the ESXi host attaches to the DVS, matching the requirement that the contract should not be deployed until the host is present.
