Question # 9

A company has deployed a VPLEX Metro protecting two applications without Cluster Witness:

-App1 distributed virtual volumes are added to CG1, which has detach-rule set cluster-1 as winner

What should be the consequence if there is a WAN COM failure for an extended period?

A.

I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -1; I/O is suspended at cluster-2

B.

I/O for CG1 is suspended at cluster -1; I/O is serviced at cluster-2I/O for CG2 is serviced at cluster -2; I/O is suspended at cluster-1

C.

I/O for CG1 is detached at cluster -1; I/O is serviced at cluster-2I/O for CG2 is detached at cluster -2; I/O is serviced at cluster-1

Question # 15

A service provider has implemented a VPLEX Metro cluster without VPLEX Witness and has implemented a static rule set. The static rule set has been set to “cluster-2 detaches”. A Microsoft Windows host in the Cluster-1 data center uses a distributed volume. However, the WAN COM fails.

What is the result of this failure?

A.

1. VPLEX suspends I/O to all distributed devices on both clusters2. VPLEX starts a delay timer3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-2 and keeps I/O suspended on Cluster-1.
