Which storage object must be created in Unisphere for PowerMax so that vCenter can automatically provision datastores to ESXi hosts?

AStorage Groups

BStorage Volumes

CMasking View

DHost Groups

Answer : A

Question 2

At a disaster planning meeting, an architect is presented with the following facts by a client:

A Unix host is replicating storage from a Production PowerMax to a VMAX 250FX.

RDF pairs have been split with Production and DR hosts accessing their respective storage.

Invalid tracks have started to build against PowerMax and VMAX 250FX.

The client now wants to bring production back to PowerMax, discarding the VMAX 250FX updates while keeping the updates on the PowerMax. What is the correct action to take?

AFailback

BEstablish

CResume

DFailover

Answer : A

Question 3

What method is used to collect host-based performance data for Windows hosts with BCSD?

ASAR

BIOSTAT

CMMC

DPERFMON

Answer : D

Question 4

How do Copy mode linked targets and NoCopy mode linked targets behave when a SnapVX unlink operation disassociates the linked target?

AOnce the copy completes, Copy mode linked targets do not contain a full and usable copy of the source devices.
Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.

BOnce the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.
Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.596.583 and later allow access to unlinked targets.

COnce the copy completes, Copy mode linked targets contain a full and usable copy of the source devices.
Behavior of NoCopy mode linked targets depends on the operating system running on the array. PowerMaxOS 5978 and HYPERMAX OS 5977.810.184 and later allow access to unlinked targets.

DOnce the copy completes, Copy mode linked targets will contain a full and usable copy of the source devices.
NoCopy mode linked targets will not allow access to unlinked targets.

Answer : B

Which optional software should be recommended to fulfill the requirement?

AProduct Suite for z/TPF

BGDPR

CzDP

DAutoSwap

Answer : C

Question 7

A storage architect is evaluating the performance of a PowerMax array during business hours. They want to know how much extra load the PowerMax can handle without significant performance degradation. The Workload Planner is used to identify the hot spots during the recurring backup windows.

Between 9:30 PM and 1:30 AM and between 3:15 AM and 5:30 AM, backups are causing the PowerMax to exceed the best practice recommendation. The Recurring System Data Exclusion Periods chart is used to filter out these hot spots. After running this workload planning for a few weeks, they notice that the selection of records they previously made are showing different numbers than when they started viewing the report, several weeks ago.

What is the explanation for this behavior?

AAfter a week the data of each time slot is refreshed with new data

BAfter two weeks the 84 data points are filled up and the report resets to default

CThe average of the viewed window has dropped below the best practice

DAfter two weeks the data of each time slot is refreshed with new data
