EMC Proven Professional – PowerMax Specialist — Question 66

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 a Dell EMC Unity to a primary host.
Which solution will meet the requirement and provide space efficiency?

Answer options

• A. Create an Asynchronous Replication session for the LUN Configure access to the replica LUN for the secondary host Attach the secondary host
• B. Create a Snapshot of the LUN Configure LUN access for the secondary host Attach the Snapshot to the secondary host
• C. Create a Snapshot of the LUN Configure secondary host connectivity to Dell EMC Unity Attach the Snapshot to 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

Correct answer: D

Explanation

The correct answer is D because Synchronous Replication ensures that changes are immediately reflected on both the primary and replica LUNs, allowing the secondary host to access the most current data efficiently. Options A and D use replication, but only D provides synchronous access, which is necessary for real-time testing. Options B and C involve Snapshots, which are not as space-efficient for ongoing access compared to replication methods.
