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?

Create a snapshot of the LUN
Configure LUN access for the secondary host
Attach the snapshot to the secondary host
Create a snapshot of the LUN
Configure secondary host connectivity to Dell EMC Unity XT
Attach the snapshot to the secondary host
Create a Synchronous Replication session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host
Create an Asynchronous Replication on session for the LUN
Configure access to the replica LUN for the secondary host
Attach the secondary host

Answer(s): 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.
