Demo Questions
Question 1
You are designing a Dell EMC Unity solution for a customer. The customer requires protection against the loss of a site for an application that is sensitive to long response times. Which Unity feature meets these requirements?
- Incremental Attach
- Asynchronous Replication
- Native SANCopy Import
- Synchronous Replication
Correct answer: B
Question 2
A customer has a Dell EMC SC9000 that supports transparent, non-disruptive volume movement among arrays. This allows the combined capacity and cache of the entire federated cluster to be seamlessly utilized for maximum performance and scalability in expanding data centers.
By leveraging the eight SC9000 arrays, what will be the total maximum raw capacity?
- 5.3 PB
- 8 PB
- 16 PB
- 24 PB
Correct answer: D

Question 3
Which value should be used for back-end sizing when planning a Dell EMC SC Series solution?
- 1x front-end throughput
- 2x front-end throughput
- 3x front-end throughput
- 4x front-end throughput
Correct answer: B
Question 4
Based on Dell EMC SC Series architecture and sizing best practices, how should the total amount of IOPS be distributed on a 2-tier solution?
- Tier 1: 50% IOPSTier 2: 50% IOPS
- Tier 1: 100% IOPSTier 2: 40% IOPS
- Tier 1: 80% IOPSTier 3: 20% IOPS
- Tier 1: 100% IOPSTier 3: 20% IOPS
Correct answer: C
Question 5
You are designing a solution for a customer who is sensitive to capacity needs. In addition, the environment consists of large read request I/O characteristics. Which Dell EMC midrange storage solution will meet the customer’s requirements?
- Unity All-Flash: Striping RAID, Dynamic Pool, and Flash 2 drivesSC Series: Data Progression and write-intensive SSDs on Tier 1
- Unity All-Flash: Parity RAID, FAST VP, and FAST CacheSC Series: FastTrack and read-intensive SSDs on Tier 1
- Unity All-Flash: Parity RAID, Dynamic Pool, and Flash 3 drivesSC Series: Data Progression and read-intensive SSDs on Tier 1
- Unity All-Flash: Striping RAID, FAST VP, and FAST CacheSC Series: FastTrack and read-intensive SSDs on Tier 1
Correct answer: B
Question 6
What is recommended to maximize system performance on Dell EMC Unity systems?
- Avoid distributing host connections across front-end ports
- Use LACP for iSCSI connectivity
- Build storage pools with many drives
- Build storage pools with fewer drives
Correct answer: C

Question 7
A Dell EMC SC Series customer has purchased the Storage Optimization bundle and wants to ensure that Data Progression works efficiently. Which snapshot schedule conforms to best practice when using Data Progression?
- Daily snapshot with an expiration of no more than 23 hours
- Daily snapshot with an expiration of exactly 24 hours
- Daily snapshot with an expiration of at least 25 hours
- Daily snapshot configured with no expiration time
Correct answer: B
Question 8
A Dell EMC SC180 is currently populated with 4 SSDs and 24 HDDs, totaling 28 disks. What is the minimum number of disks that can be licensed for expansion?
- 10
- 14
- 20
- 28
Correct answer: B
Explanation:
The SC180 enclosure can be connected to a SCv2080 to add additional storage beyond the base unit capacity. • The maximum number of drives that can be part of a SCv2080 as of SCOS release 7.1 is 168. • The SC180 enclosure contains 84 drive slots. • The minimum number of spinning (HDDs) or solid state (SSD) drives in an SC180 is 28. Drives can only be added in increments of 14. • The SC180 is only supported as an expansion unit with the SCv2080. • They are not sold separately. • If you are familiar with the SC280 enclosure, the SC180 is similar but the enclosures are not interchangeable. • The SC280 can be sold separately but only works with an SC4020, SC8000 or SC9000. • It will not work on a SCv2080.
