   What is a benefit of combining mirroring with snapshots in a data protection strategy?

   • ASnapshots can be used to create a mirror relationship.
   • BMirroring provides local recovery, and snapshots provide remote replication.
   • CMirroring can replace snapshots, so snapshots are unnecessary.
   • DMirroring provides remote disaster recovery, while snapshots provide local point-in-time recovery.

   A hospital's E-Series array hosts an EHR database volume that is updated continuously. The compliance team requires the ability to restore the database to its state at 2:00 AM each day for the last 30 days, but they do not want to consume a full copy of the data for each day. Which SANtricity feature should the storage administrator use to meet this requirement with minimal storage overhead?

   • AConfigure synchronous mirroring to a remote array and keep the remote volume for 30 days.
   • BConfigure a snapshot group with a 30-day retention policy and a daily schedule.
   • CCreate 30 full volume copies, one for each day, and store them on a separate volume group.
   • DEnable the snapshot schedule but set the retention to 'keep all' without a limit.

The administrator wants to revert the volume to its pre-update state as quickly as possible, and the volume is currently not in use. What should the administrator do?

   • AUse the volume copy feature to copy the snapshot to the original volume.
   • BDelete the corrupted volume and recreate it from the snapshot.
   • CPerform a rollback operation on the volume using the snapshot.
   • DCreate a new volume from the snapshot and manually copy the data back.

   A company has a primary E-Series array and a secondary array at a DR site. They have configured synchronous mirroring for a critical volume. The WAN link between the sites experiences intermittent high latency. The application team complains that write performance has degraded significantly.

   • ADisable mirroring and rely on local snapshots.
   • BSwitch to asynchronous mirroring for the volume.
   • CIncrease the WAN bandwidth.
   • DReduce the number of volumes in the mirror relationship.
