EMC Proven Professional – PowerMax Specialist — Question 12

A storage administrator is tasked with creating a DR solution for block and file storage resources on a Dell EMC Unity 650F system at a primary production site.
The company has two other campus locations.
Campus A is located 50 km away and has a Dell EMC Unity 400 Hybrid system. Campus B is located 200 km away and has a Dell EMC UnityVSA system.
What should the storage administrator do to provide the best protection of storage resources while meeting recommended latency levels?

Answer options

• A. Replicate block storage resources synchronously to Campus A Replicate file storage resources asynchronously to Campus B
• B. Replicate block storage resources synchronously to Campus A Replicate file storage resources synchronously to Campus A
• C. Replicate block storage resources asynchronously to Campus A Replicate file storage resources synchronously to Campus A
• D. Replicate block storage resources asynchronously to Campus B Replicate file storage resources asynchronously to Campus A

Correct answer: C

Explanation

The correct option, C, ensures that block storage is replicated asynchronously to Campus A, which is within the recommended latency range, while file storage is replicated synchronously to that same campus for immediate access. Options A and B do not optimize latency for the file storage, and option D places both types of storage at Campus B, which is too far to meet latency requirements.
