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?
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?
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.

Question 3 of 152
What is the Dell EMC best practice for sizing and designing a Dell EMC SC Series solution?
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?
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?
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.
