NEW QUESTION # 91
A customer must provision file systems on a Dell Unity XT 480F for a test environment. A dynamic pool will be configured with RAID 5 (4+1) protection to match the production pool. The used tier contains only SAS Flash 3 drives. What is the minimum drive count necessary to create this pool?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: B
Explanation:

* Minimum Drive Count:
* For creating a dynamic pool with RAID 5 (4+1), the configuration must include at least 2 RAID 5 (4+1) groups to ensure redundancy and performance.
* The minimum drive count for this setup would be 2 * (4 + 1) + 1 (hot spare) = 11 drives.
* RAID 5 Requirements:
* This configuration ensures that the dynamic pool has enough drives to maintain performance and data protection according to Dell's best practices.
* Dell Midrange Storage References:
* Dell Unity XT documentation provides detailed guidelines on RAID configurations and the minimum drive requirements for dynamic pools.
* Community forums and support resources from Dell Technologies offer insights into best practices for configuring RAID and dynamic pools.

A Dell EMC PowerStore customer plans to migrate storage volumes across appliances within a cluster. They want to use minimal effort to ensure that the appliance avoids reaching full capacity.
Which method is recommended?
- A. Resource Balance
- B. Volume Placement
- C. Live Migrate
- D. Assisted Migration
Answer: D
Explanation:
Assisted migration -In the background, the system periodically monitors storage resource utilization across the appliances. Migration recommendations are generated based on factors such as drive wear, appliance capacity, and health. If you accept a migration recommendation, a migration session gets automatically created.

Which methods are available to migrate storage resources from one Dell PowerStore appliance to another within the same cluster?
- A. Migrate and Assisted Migration
- B. Assisted Migration and Volume Motion
- C. Assisted Migration and Live Migrate
- D. Volume Motion and Live Migrate
Answer: B
Explanation:
The Dell PowerStore appliance provides two methods to migrate storage resources within the same cluster: Assisted Migration and Volume Motion.
Assisted Migration: This method allows the administrator to manually initiate and control the migration process, and it allows for the migration of individual resources such as LUNs, file systems and snapshots.
Volume Motion: This method allows the administrator to move a LUN or file system from one storage pool to another on the same PowerStore appliance or within the same cluster. This is done without any disruption to the hosts accessing the data and it can be automated with the use of policies. It's important to note that the Live Migrate and Migrate options are not available to migrate storage resources within the same cluster in Dell PowerStore.

NEW QUESTION # 102
How should Dell Unity XT storage pools be configured to minimize the chance of running out of space due to snapshot utilization?
- A. Change the number of days in the local retention policy
- B. Set retention to a particular date and time
- C. Set high and low watermarks to remove old snapshots
- D. Change the frequency period on the snapshot schedule
Answer: C
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.
