Question 1

A storage administrator wants to view additional performance metrics for their VPLEX cluster. The administrator runs the report create-monitors command to help with this task.

ADisks, ports, and volumes

BDisks, volumes, and hosts

CDisks, storage views, and ports

DDisks, initiators, and storage volumes

Answer : A

Question 2

What are characteristics of a storage view?

AAn initiator can be in multiple storage viewsVPLEX FE port can only be in one storage viewEach initiator and FE port pair can only be in one storage view

BAn initiator can only be in one storage viewVPLEX FE port can be in multiple storage viewsEach initiator and FE port pair can be in different storage views

CAn initiator can only be in multiple storage viewVPLEX FE port can be in multiple storage viewsEach initiator and FE port pair must be in different storage views

DAn initiator can be in multiple storage viewsVPLEX FE port can be in multiple storage viewsEach initiator and FE port pair can only be in one storage view

Answer : C

Question 3

Using the Storage Volume expansion method for virtual volumes built on RAID-1 or distributed RAID-1 devices, what is the maximum number of initialization processes that can run concurrently, per cluster?

A100

B250

C500

D1000

Answer : D

Question 4

What is the purpose of issuing the batch-migrate check-plan command?

ADetermines if there is currently enough back-end bandwidth

BDetermines if the front-end IO rate is below the predetermined threshold

CVerifies that the target devices have no virtual volumes configured

DVerifies that the source devices are not in a storage view

Answer : C

Question 5

Why is it EMC best practice that each back-end LUN has a connection to all the A-directors and to all the B-directors in the VPLEX cluster?

APrevents data unavailability during a non-disruptive upgrade

BReduces the number of ITLs

CEnsures writes are mirrored on director local cache

DOptimizes global read cache

Answer : A

Question 6

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?

AThere is storage volume contention on Cluster-2

BA WAN COM failure has occurred

CDistributed device I/O is exceeding WAN COM bandwidth

DDevice mobility jobs are moving data across the WAN COM

Answer : C

Question 7

What can be used to monitor VPLEX performance parameters?

AVPLEX Cluster Witness

BUnisphere Performance Monitor Dashboard

CEMC SolVe Desktop

DEMCREPORTS utility

Answer : B
