NEW QUESTION # 14
A systems administrator has deployed a Dell Unity XT 380F system with 15x 1.92 TB SSD drives, in a RAID 5 dynamic pool Shortly after deployment, the administrator wants to expand the capacity of the system and use larger drives to increase the density What will happen if the administrator adds 4x 3 84 TB SSD drives?
- A. Three of the drives will be added with a fourth reserved as spare
- B. The mixing of drive types is not supported and the operation will fail
- C. The full capacity of the drives will be available
- D. Only half of the capacity of the new drives will be available
Answer: B
Explanation:
Dell Unity XT systems does not support mixing different drive types in the same RAID group.
Adding larger drives to an existing RAID group with smaller drives will cause the operation to fail.
The administrator should create a new RAID group with the larger drives and then copy the data from the old RAID group to the new one.

Answer: C
Explanation:
When connecting Disk Array Enclosures (DAEs) to SAS ports on a Dell Unity XT DPE (Disk Processor Enclosure) with only two ports available on each SP (Storage Processor), the recommended order is DAE 1 to SAS Bus 0, DAE 2 to SAS Bus 1, and DAE 3 to SAS Bus 0. This configuration helps in balancing the load across the available SAS ports, ensuring optimal data flow and performance.

NEW QUESTION # 19
Which two workload parameters are required to proceed with sizing for a PowerStore solution?
(Select 2)
- A. IOPS
- B. Effective Capacity
- C. Data reduction ratio
- D. Response time
Answer: A,B
Explanation:
Sizing for PowerStore Solutions:
Accurate sizing for PowerStore solutions requires specific workload parameters to ensure that the storage system meets performance and capacity requirements.
Required Parameters:
IOPS (Input/Output Operations Per Second): A key performance metric indicating the number of read/write operations the system must handle. Essential for determining the required performance capability.
Effective Capacity: The usable storage capacity after considering data reduction technologies like compression and deduplication. Critical for ensuring the system can accommodate the data volume.
NEW QUESTION # 20
A customer wants to expand their Dell EMC Unity Hybrid system, which includes a pool of 64 drives in a RAID 5 (4+1) configuration.

NEW QUESTION # 23
A database volume on a Dell PowerStore cluster has a Protection Policy that is applied with a single snapshot rule. The policy takes a snapshot every hour and retains them for 48 hours. The storage administrator must present a copy of the database volume to a test environment Which action does the storage administrator take to meet this requirement?
- A. Create a snapshot of the database volume and map it to the test host
- B. Create a thin clone of the database volume and map it to the test host
- C. Restore the snapshot to a new test volume
- D. Create a new snapshot policy for the test volume
Answer: B
Explanation:
A thin clone is a writeable copy of a volume, which shares the same data blocks as the parent volume. This allows the administrator to provide a copy of the production database volume to the test environment without affecting the production data. It also allows to test the data without affecting the production data, and also it doesn't require additional storage space.
NEW QUESTION # 24
A customer has a PowerStore 3200T system with only base enclosure consisting of 15 SSD 1920 GB drives and wants to expand the available capacity. What is the most cost-effective drive addition from a raw and usable capacity perspective to achieve the result wanted by the customer?
- A. 6 x 1920 NVMe SSD drives
- B. 6 x 750 GB NVMe SCM drives
- C. 6 x 3840 NVMe SSD drives
Answer: C
Explanation:
Adding 6 x 3840 GB NVMe SSD drives is the most cost-effective way to expand the capacity of a PowerStore
3200T system. This addition provides a significant increase in both raw and usable capacity, offering a better balance of performance and cost compared to smaller or more expensive drive options.
