What is the EMC recommendation when configuring the number and size of each LUN in the reserved LUN pool when performance data is unknown?

A SnapView session is started on a source LUN at 1:20 P.M. The snapshot is activated and assigned to a secondary host. The secondary host makes changes to the snapshot.

The storage administrator removes the source LUN from the primary host’s storage group at 2:15 P.M. and removes the snapshot from the secondary host’s storage group at 2:30 P.M. A rollback operation is started at 3:15 P.M.

Which data will the source LUN contain once the rollback completes?

A customer wants to ensure that their SnapView snapshots will remain accessible even in the event of an SP failure. How will they need to create those snapshots?

What happens when a snapshot is deactivated?

A CLARiiON CX4 has SnapView enabled. Management is performed through the command line. What happens if the “-persistent” flag is omitted from the session start command and an SP fails?

A clone is fractured at 1:30 P.M. It is then used for write-intensive testing by a secondary host. The storage administrator starts a Protected Restore at 2:30 P.M. The restore finishes at 3:15 P.M.
Which data will the clone contain at 4:00 P.M?

Refer to the Exhibit.

A customer uses the Instant Restore feature. As shown in the exhibit, data blocks A and B have already

been restored. If the I/O is meant for data block E, which data block is restored next?
