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?
A
Explanation:
"The engineer should design a system to handle all, or nearly all, IOPS in one particular tier"
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?
D
What is the Dell EMC best practice for sizing and designing a Dell EMC SC Series solution?
C
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?
B
A customer site has four NAS servers participating in MetroSync replication. Which Dell EMC Unity
feature could reduce failover times?
B
What is a benefit of cross-platform replication between Dell EMC SC Series and Dell PS Series arrays?

You are upgrading a Dell EMC Unity array to a Dell EMC PowerStore 1000 T array. The customer asks
what they need to do so they can map PowerStore snapshots from the new PowerStore array to a
host.
What should be your response?
D
Explanation:
"Volume and Volume Group Snapshots: Snapshots cannot be mapped to a host. To view the contents
of a snapshot, you must first clone the snapshot then map the clone to a host."
