Correct Answer: C
A requirement forSmart DR(Disaster Recovery) in Nutanix Files is thatprimary and recovery file servers must support the same protocols. Smart DR is a feature that enables automated disaster recovery for Nutanix Files by replicating file shares between a primary site and a recovery site, ensuring business continuity in case of a failure.
According to theNutanix Unified Storage Administration (NUSA)course, "Smart DR requires that the primary and recovery file servers support the same file-sharing protocols (e.g., SMB, NFS) to ensure seamless failover and consistent client access." This ensures that clients can access the same shares with the same protocol after a failover, maintaining application compatibility and user experience.
TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that "Smart DR configurations mandate that the primary and recovery file servers are configured with identical protocol support to enable consistent replication and recovery of file shares." For example, if the primary file server uses SMB for Windows clients, the recovery file server must also support SMB.
The other options are incorrect:
* Primary and recovery file servers must have different domain names: Smart DR does not require different domain names. In fact, using the same domain name can simplify AD integration and client access during failover.
* File servers may have different FSVM numbers at the primary and recovery sites: While Smart DR allows flexibility in FSVM counts, it is not a requirement. The number of FSVMs can be the same or different based on site resources, but this is not mandated.
* The Files Manager must have only one file server: Nutanix Files Manager can manage multiple file servers, and Smart DR does not restrict the environment to a single file server.
The NUSA course documentation highlights that "Smart DR ensures protocol consistency between primary and recovery sites to support seamless failover, making protocol support a critical requirement for configuration." References:
