   Which characteristic is typical of synchronous replication in Dell Unity?

   • AReplication occurs at scheduled intervals, reducing network load
   • BThe destination is updated only after a snapshot is taken on the source
   • CThe source and destination are always in sync, with no data loss on failover
   • DIt is designed for long-distance replication with high latency

   An administrator needs to permanently remove an asynchronous replication session between two Dell Unity arrays. The session is no longer needed because the DR site is being decommissioned. What should the administrator do to ensure the session is removed and the destination LUN is not left in a read-only state?

   • ADelete the replication session
   • BPerform a failover and then delete the session
   • CResume the replication session
   • DPause the replication session

   A synchronous replication session between two Dell Unity arrays is in a 'Degraded' state because the primary array has failed. The administrator needs to make the secondary array available to hosts to restore service. What is the correct procedure?

   • APerform a failover on the replication session to promote the secondary array to primary
   • BPause the replication session and then present the secondary LUN to hosts
   • CResume the replication session to allow the secondary to catch up
   • DDelete the replication session and then present the secondary LUN to hosts

   After a failover was performed on a synchronous replication session due to a primary array failure, the original primary array has been repaired and is back online. The administrator wants to return production to the original primary array with minimal data loss. What is the correct procedure?

   • ADelete the replication session and create a new one in the opposite direction
   • BPause the replication session and then resume it
   • CPerform a test failover to validate the original primary
   • DPerform a failback on the replication session

   A Dell Unity administrator is performing planned maintenance on the WAN link between the primary and secondary sites. The link will be down for 30 minutes. The administrator wants to ensure that the asynchronous replication session does not report an error during this time and that replication resumes automatically once the link is restored. What should the administrator do?

   • APause the replication session before the maintenance and resume it after the link is restored
   • BDo nothing, as the session will automatically pause and resume
   • CPerform a failover to the secondary site before the maintenance
   • DDelete the replication session and recreate it after the maintenance
