A storage administrator is planning to move a NAS server to the peer SP on a Dell Unity XT system. The NAS server and two of its associated file systems have active asynchronous replication sessions…

Question

Options

• ASet the RPO value to 1440 for the NAS server and file system replication sessions.
• BFailover the replication sessions for the NAS server and file systems.
• CManually pause the replication sessions for the NAS server and file systems.
• DSynchronize the NAS server and file system replication sessions.

• A
  12% (6)
• B
  6% (3)
• C
  59% (30)
• D
  24% (12)

Explanation

Manually pausing the replication sessions (C) is the required prerequisite before moving a NAS server to the peer SP on a Dell Unity XT, because active asynchronous replication sessions cannot follow the NAS server mid-transfer - pausing them cleanly suspends synchronization without altering ownership or triggering a failover, allowing the move to complete and replication to be resumed afterward.

Why the distractors are wrong:

• A (Set RPO to 1440): RPO is a policy setting defining maximum acceptable data loss interval; changing it has no effect on enabling or preparing a NAS server move between SPs.
• B (Failover): Failover transfers NAS server ownership to the remote system for disaster recovery purposes - this is the wrong direction and far more disruptive than a local SP move.
• D (Synchronize): Synchronizing ensures the remote copy is current, but it doesn't place the sessions in a state that accommodates a local SP migration; active sessions still need to be paused.

Memory tip: Think "PAUSE before you PLACE" - just as you pause a recording before moving equipment, you pause replication before placing the NAS server on the peer SP.
