EMC Proven Professional – PowerMax Specialist — Question 39

When the LUN Snapshot Restore operation is performed, what does the Unity system automatically do before beginning the restoration process?

Answer options

• A. Detaches the hosts from the snapshot
• B. Creates a copy of the snapshot
• C. Detaches the host from the LUN
• D. Creates a snapshot of the LUN

Correct answer: B

Explanation

The correct answer is B because the Unity system creates a copy of the snapshot to ensure data integrity during the restore process. Options A and C are incorrect as they refer to host disconnection, which is not an automatic step in the restoration. Option D is also incorrect because the system does not create a new snapshot before restoring; it uses the existing one.
