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

C. Distributed device I/O is exceeding WAN COM bandwidth

D. Device mobility jobs are moving data across the WAN COM

What is the relationship between a storage volume and an extent?

A. A storage volume can be split into multiple extents

B. An extent must map to an entire storage volume

C. A storage volume can be created out of multiple extents

D. An extent can span multiple storage volumes

What is a VPLEX RAID-0 device?

A. Device that stripes data beneath a top-level device

B. Device that concatenates data on a top-level device

To which VPLEX component does the SNMP management station connect to gather statistics?

A. VPLEX Witness

B. Management server

C. Director-A

D. Director-B

VPLEX Metro has been added to an existing HP OpenView network monitoring environment. The VPLEX SNMP agent and other integration information have been added to assist in the implementation. After VPLEX is added to SNMP monitoring, only the remote VPLEX cluster is reporting performance statistics.

What is the cause of this issue?

A. Local VPLEX Witness has a misconfigured SNMP agent.

B. HP OpenView is running SNMP version 2C, which may cause reporting that does not contain the performance statistics.

C. TCP Port 443 is blocked at the local site's firewall.

D. Local VPLEX cluster management server has a misconfigured SNMP agent.

What happens to global cache size if a director fails and is removed from the cluster?

A. Suspends

B. Increases

C. Decreases

D. Remains as-is

Which command collects the most recent performance statistics from all VPLEX directors?

A. SNMPGETBULK

B. monitor stat-list

C. SNMPGET
