[Configure and Utilize Nutanix Unified Storage] An administrator wants to use Smart DR to ensure that in the event of an unplanned loss of service…

SmartDR can provide automatic client redirection only when the SMB shares being replicated are published through a Microsoft DFS-Namespace. DFS automatically updates referrals after a SmartDR fail-over, so users are transparently redirected to the recovered file server with no manual DNS or client action.

A – An asynchronous replication schedule alone does not move client connections; users must manually reconnect.

C – Stretching the subnet keeps IPs identical, but SmartDR still requires client reconnects or a floating VIP mechanism not provided here.

D – Snapshots protect data but have no effect on directing clients during a cluster-level outage.
