Question 11:
Refer to the exhibit.
A virtual volume created on a distributed device is experiencing performance problems. The virtual volume is in a storage view in Cluster-1.
What could be the issue?
A. There is storage volume contention on Cluster-2
B. A WAN COM failure has occurred

A. Virtual volume VPD
B. UUID of back-end LUN
C. VML ID
D. WWN: WWPN
Correct Answer: D
Question 13:
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 clusters
2.
VPLEX starts a delay timer
3.
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.
B. 1. VPLEX starts a delay timer
2.
VPLEX suspends I/O to all distributed devices on both clusters
3.
If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2.
C. 1. VPLEX suspends I/O to all distributed devices on both clusters 2.VPLEX starts a delay timer
3. If connectivity is not restored within the timer expiration period, VPLEX resumes I/O on Cluster-1 and keeps I/O suspended on Cluster-2.
D. 1. VPLEX starts a delay timer
2.
VPLEX suspends I/O to all distributed devices on both clusters
3.
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.
