A storage administrator is required to test a new version of an application loaded on a secondary host. The administrator must use existing data contained on a LUN provisioned from Dell EMC Unity XT to a primary host.
Which solution will meet the requirement and provide space efficiency?
A . Create a snapshot of the LUN
Configure LUN access for the secondary host
Attach the snapshot to the secondary host
B . Create a snapshot of the LUN
Configure snapshot access to the LUN for the secondary host
Attach the snapshot to the secondary host
C . Create a Synchronous Replication session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host
D . Create an Asynchronous Replication on session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host
Answer: B
Explanation:
Attaching a snapshot is only applicable for block snapshots, and makes the snapshot available for host IO. A host must have Snapshot access or LUN and Snapshot access configured in order to access the snapshot. When a snapshot is attached, Unisphere provides the option to create a copy of the snapshot in case the administrator wants to preserve the current snapshot view for future use.
