Demo Questions
Question 1
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?
- Size Tier 1 for 100% of the adjusted IOPS
- Use distributed adjusted IOPS for all tiers
- Use distributed adjusted IOPS for Tiers 1 and 2 only
- Size Tier 2 for 100% of the adjusted IOPS
Correct answer: B
Question 2
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?
- 8
- 10
- 12
- 16
Correct answer: B
Question 3
What is the Dell EMC best practice for sizing and designing a Dell EMC SC Series solution?
- Front-end ports required for performance should always meet capacity needs
- Drive capacity should meet performance needs
- Size for performance first and capacity second
- Size for capacity; Data Progression should always meet performance needs
Correct answer: B
Question 4
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?
- Wait until the end of the quarter and collect a week-long sampling
- Take a single-day sampling on any given day because that is sufficient in most instances
- Wait until the end of the quarter and collect a single-day sampling
- Take a week-long sampling on any given week because that is sufficient in most instances
Correct answer: A
Question 5

- QoS Failover Policy
- Cabinet Failover
- SRDF Metro
- Consistency Groups
Correct answer: D
Question 6
What is a benefit of cross-platform replication between Dell EMC SC Series and Dell PS Series arrays?
- Leverages existing interfaces
- Enables replication of volume collections
- Supports cascade mode for the PS Group
- Provides active snapshot replication
Correct answer: D
Question 7
Recent legislation requires a government customer to enhance data security by utilizing D@RE with SED drivers and use Level 3 certified security. Which KMS product should be recommended for use with Dell EMC SC Series arrays?

Question 9
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?
- Create a volume group of the snapshot.
- Create a read/write snapshot of the snapshot
- Create a copy of the snapshot
- Create a thin clone of the snapshot
Correct answer: A
Question 10
Which features were introduced in SCOS 7.3?
