Question 1 of 152

You are designing a two-tiered Dell EMC SC Series solution that will be optimized for performance. You gather the necessary data from Live Optics and find that the read/write ratio is 80:20.

What approach is recommended?

Answer choices
Show answer

Correct answer: A

To optimize a Dell EMC SC Series solution for performance, especially with a read/write ratio of 80:20, it is recommended to size Tier 1 to handle 100% of the adjusted IOPS. This ensures that the higher-performance tier can accommodate the entire IOPS workload, providing better performance and reducing latency.

Question 2 of 152

You are sizing a new Dell EMC SC Series array. Upon analyzing the Live Optics report, you find the current system has a peak throughput of 4687 MB.

What is the minimum number of 10Gb iSCSI front-end ports required to meet the throughput needs?

Answer choices
Show answer

Correct answer: D

To determine the minimum number of 10Gb iSCSI front-end ports required to meet the throughput needs, we divide the peak throughput by the maximum throughput per port. Each 10Gb iSCSI port can handle up to 600MB/s. Thus, 4687 MB/s divided by 600 MB/s per port equals approximately 7.8 ports. In a dual-controller setup, to ensure redundancy and failover capability, the requirement doubles, leading to a minimum of 16 ports. Therefore, the correct answer is 16.

Answer choices
Show answer

Correct answer: C

The best practice for sizing and designing a Dell EMC SC Series solution is to prioritize performance over capacity. Ensuring that the solution meets performance requirements first is crucial to achieving optimal operation, and capacity considerations should follow to ensure that the performance needs are not compromised.

Question 4 of 152

You plan to schedule a Live Optics sampling with your customer to size a Dell EMC SC Series array. However, the customer wants to postpone the run until the end of the quarter because there could be more activity on the current storage system.

What course of action is recommended?

Answer choices
Show answer

Correct answer: B

For sizing a Dell EMC SC Series array, it is recommended to take a single-day sampling on any given day because that is generally sufficient. The reason is that storage usage patterns are often consistent, and waiting for a particular time period might delay the process. Conducting a 24-hour collection allows for prompt continuation with the sales process, and customers can always run additional samples if required.

Question 5 of 152

A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity feature could reduce failover times?

Answer choices
Show answer

Correct answer: B

Cabinet Failover reduces failover times by simultaneously failing over all synchronously replicated NAS servers and associated VMware vSphere NFS datastores to the peer system in parallel. This ensures a faster recovery process during critical failures or outages.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
