A customer is managing a Dell EMC SC7020 array running SCOS 7.2. The array is running out of capacity. The customer asks you to begin scoping the system for additional drives.
What disk drive redundancy rule applies to 3.84 TB SSDs?
- A . Forced Dual Redundancy
- B . Default Dual Redundancy
- C . Default Single Redundancy
- D . Forced Non-Redundancy
A systems administrator has deployed a DellUnity XT 380F with 90x 1.92 TB SSDs in a dynamic pool How many drives are allocated as spare space?
- A . 0
- B . 4
- C . 3
- D . 2
B
Explanation:
The Dell Unity XT 380F has a default spare space allocation of 4% of the total number of drives in a dynamic pool. So with 90x 1.92 TB SSDs, 4 drives will be allocated as spare space. These spare drives are used to automatically replace a failed drive, ensuring data availability and protection.

- A . 960 GB, 1920 GB, 3840 GB, and 7680 GB
- B . 960 GB, 1920 GB, and 3840 GB only
- C . 1920 GB, 3840 GB, 7680 GB, and 15360 GB
- D . 1920 GB, 3840 GB, and 7680 GB only
C
Explanation:
What is a characteristic of single-tier Flash on Dell EMC SC Series arrays?
- A . Supports both write-intensive and read-intensive SSDs in the same tier
- B . Snapshot data is kept on Tier1 in RAID 10 to optimize performance
- C . Read only data is migrated to lower tiers when a snapshot is taken
- D . Supports either write-intensive or read-intensive SSDs in the same tier

- B . 24
- C . 32
- D . 64
How should Dell Unity XT storage pools be configured to minimize the chance of running out of space due to snapshot utilization?
- A . Set high and low watermarks to remove old snapshots
- B . Set retention to a particular date and time
- C . Change the number of days in the local retention policy
- D . Change the frequency period on the snapshot schedule
A
Explanation:
Dell Unity XT storage pools can be configured to minimize the chance of running out of space due to snapshot utilization by setting high and low watermarks to remove old snapshots. A high watermark is set to specify the maximum amount of space that can be consumed by snapshots before the oldest snapshots are automatically removed. This is a good way to ensure that snapshots do not consume all available space, and helps to prevent the pool from running out of space.
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?
