A network engineer demonstrates Cisco ACI to a customer. One of the test cases is to validate a disaster recovery event by resetting the ACI fabric to factory and then restoring the fabric to the state it was in before the event. Which setting must be enabled on ACI to export all configuration parameters that are necessary to meet these requirements?

Suggested answer: B

Explanation:

Immediate—Specifies that EPG policies (including contracts and filters) are downloaded to the associated leaf switch software upon ESXi host attachment to a DVS. LLDP or OpFlex permissions are used to resolve the VM controller to leaf node attachments.

The policy will be downloaded to leaf when you add host to the VMM switch. CDP/LLDP neighborship from host to leaf is required.

On Demand—Specifies that a policy (for example, VLAN, VXLAN bindings, contracts, or filters) is pushed to the leaf node only when an ESXi host is attached to a DVS and a VM is placed in the port group (EPG).

The policy will be downloaded to leaf when host is added to VMM switch and virtual machine needs to be placed into port group (EPG). CDP/LLDP neighborship from host to leaf is required.

With both immediate and on demand, if host and leaf lose LLDP/CDP neighborship the policies are removed.
