Protection Domains (PDs) in Nutanix ensure that entire applications and their associated data are protected during failover.However,Volume Groups (VGs) are not automatically includedunless explicitly configured.
* Option A (Select "Auto protect related entities") is correct:
* This setting ensures thatassociated Volume Groups, networks, and other dependencies are included in the Protection Domainautomatically.
* Without enabling this, only the VM itself would be protected, leading tomissing application data upon failover.
* Option B (Manually add Volume Groups to Protected Entities) is correct:
* If"Auto protect related entities" is not enabled, the administrator mustmanually add Volume Groups to the Protection Domain.
* This ensures that bothVMs and their attached Volume Groupsare replicated and recovered together.
* Option C (Place Volume Groups in a separate Protection Domain) is incorrect:
* Separating Volume Groups into a different PDdoes not guarantee they failover together with VMs.
* It is best practice tokeep related VMs and Volume Groups in the same PD.
* Option D (Use application-consistent snapshots) is incorrect:
* Whileapplication-consistent snapshots improve data integrity, theydo not fix missing Volume Groups in failover scenarios.
