Question 32

An administrator is using Unisphere for PowerMax Workload Planner to assess the performance and compliance of a PowerMax Storage Group (SG).

How does the Planner calculate if the Storage Group workload is fully compliant?

Options:

Weighted SG average response times for the past 30 minutes

Weighted SG average response time for the past 8 hours and past one week

Weighted SG average response time for the past 4 hours and past two weeks

Weighted SG average response time for the past 4 hours and past one week

I highly recommend Cramkey Dumps to anyone preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Dexter Aug 7, 2024

Agreed. It's definitely worth checking out if you're looking for a comprehensive and reliable study resource.

Alaya

Best Dumps among other dumps providers. I like it so much because of their authenticity.

Kaiden Sep 16, 2024

That's great. I've used other dump providers in the past and they were often outdated or had incorrect information. This time I will try it.

Kingsley

Do anyone guide my how these dumps would be helpful for new students like me?

Haris Sep 11, 2024

Absolutely! They are highly recommended for anyone looking to pass their certification exam. The dumps are easy to understand and follow, making it easier for you to study and retain the information.

Ayesha

They are study materials that are designed to help students prepare for exams and certification tests. They are basically a collection of questions and answers that are likely to appear on the test.

Ayden Oct 16, 2024

That sounds interesting. Why are they useful? Planning this week, hopefully help me. Can you give me PDF if you have ?

Question 33

A systems administrator no longer needs the remote replica of a local device. Which step can be performed first in order to perform the deletepair function?

Options:

Suspend the SRDF link

Split the SRDF link

Change the type of the group to "regular

Change the pair state to "NR"

Question 34

An administrator is using the Workload Planner feature in Unisphere for PowerMax

How does the Planner calculate if the Storage Group workload is stable?

Options:

One of the calculated values is within 10-20% of the SL-defined response time

Both calculated values are within a 10-15% threshold of the SL-defined response time

One of the calculated values remains within the SL-defined response time

Both calculated values are within the SL-defined response time.

Explanation:

Step by Step Comprehensive Detailed Explanation:

The Workload Planner in Unisphere for PowerMax helps you analyze and predict the performance impact of adding new workloads to your storage array. It uses sophisticated algorithms to calculate howthe addition of a new workload will affect the existing workloads and whether it will violate any service level objectives (SLOs).

To determine if a Storage Group workload is stable, the Planner considers two key calculated values:

Read Response Time:The predicted read response time of the Storage Group after the new workload is added.

Write Response Time:The predicted write response time of the Storage Group after the new workload is added.

The Planner compares these calculated values against the service level (SL) defined for the Storage Group. Ifboththe calculated read and write response times fall within the defined SL response time, the Planner considers the workload to be stable. This means that the new workload can be added without negatively impacting the performance of the existing workloads or violating the SLOs.

Why other options are incorrect:

A. One of the calculated values is within 10-20% of the SL-defined response time:Both read and write response times must be within the defined SL, not just one.

B. Both calculated values are within a 10-15% threshold of the SL-defined response time:The threshold is not fixed at 10-15%. The calculated values must be within the actual SL-defined response time.

C. One of the calculated values remains within the SL-defined response time:Again, both read and write response times need to be within the defined SL.
