   An administrator needs to create a synchronous replication session for a VMFS datastore on a Dell Unity array. The destination array is already configured with a replication interface and a storage pool. The administrator wants to ensure that the session is created correctly and can be managed later. What is the correct procedure in Unisphere?

   • ASelect the destination datastore, choose Replication > Create, specify the source array and pool, and set the replication type to Synchronous
   • BCreate a snapshot of the source datastore and then replicate the snapshot to the destination
   • CSelect the source datastore, choose Replication > Create, specify the destination array and pool, and set the replication type to Synchronous
   • DUse the CLI command 'replication session create' with the source and destination LUN IDs

   A company has an asynchronous replication session for a file server between two Dell Unity arrays. The RPO is set to 1 hour, and the session status is 'OK'. However, the administrator notices that the actual RPO is consistently 2 hours. The WAN link is not congested, and the source array is not under heavy load. The administrator checks the replication performance metrics and sees that the replication throughput is lower than expected. What is the most likely cause of the RPO being exceeded?

   • AThe replication bandwidth limit is set too low
   • BThe destination array is under heavy load
   • CThe RPO is set too high
   • DThe replication session is paused
