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

NEW QUESTION 40
An administrator's Unity system is configured with both a Fibre Channel CNA and a Fibre Channel I/O module.
Which Fibre Channel port on each SP must be used for native synchronous replication?
- A. I/O module FC port 5
- B. I/O module FC port 2
- C. CNA FC port 5
- D. CNA FC port 4
Answer: D
Explanation:
Only one FC port can be configured and used for synchronous replication. Once an FC port is assigned, it will continue to act as the synchronous replication port and can never be changed. To determine the FC port used for synchronous replication, in the CLI console, run the command /remote/sys show -detail. Port information, similar to the following example, will appear in the output:
Synchronous FC ports = spb_fc4, spa_fc4
