EMC Proven Professional – Network Attached Storage Specialist — Question 10

What determines which cluster will service I/O in the event of a WAN COM failure for a distributed device that is not a member of a consistency group?

Answer options

• A. Rule set of the distributed device
• B. VPLEX Witness
• C. Detach rule of the consistency group
• D. Detach rule of the storage view

Correct answer: B

Explanation

The VPLEX Witness is the component responsible for determining which cluster will manage I/O in case of a WAN COM failure for non-consistency group devices. The other options, such as the rule set of the distributed device, the detach rule of the consistency group, and the detach rule of the storage view, do not influence the I/O servicing decision during such failures.
