Specialist - Technology Architect. PowerMax and VMAX All Flash Solutions Exam Questions and Answers

Question 1

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

Options:

A.

Once 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.

B.

Once 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.

C.

Once 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.

D.

Once 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.

Question 2

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?

Options:

A.

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

B.

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

C.

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

D.

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

Question 3

A storage architect is looking for best practices to expand an existing single V-Brick VMAX All Flash 250. They are planning to expand the VMAX configuration to a dual V-Brick model for better performance.

What is a consideration?

Options:

A.

Both V-Bricks must contain 1 TB of cache each

B.

RAID type of both V-Bricks must be the same

C.

Cache size of both V-Bricks must be equal

D.

Number of drives must be less than or equal to 96
