Question 1

When can you consider using Virtual Synthetic Backups with a PowerProtect DD appliance?



Answer : B

Virtual Synthetic Backups are an efficient method for consolidating full and incremental backups without moving large amounts of data. This method is particularly useful when restores are frequent because it reduces the time and resources required to create new full backups. Instead, it synthesizes a full backup from previous full and incremental backups, making the restore process faster and more efficient. This helps to optimize performance and minimize the strain on the backup system during frequent restores.


Question 2

SIMULATION

Task

Use the simulator to schedule PowerProtect DD space reclamation to occur every Monday at 4:00

AM without impacting system resources for more than 25%.

When you have finished, continue to the next question.



Answer : A

To schedule space reclamation on a PowerProtect DD system as specified, here's the general procedure to follow in the DD System Manager:

Log into DD System Manager: Access the management interface for your PowerProtect DD system.

Navigate to Data Management: In the sidebar, look for an option labeled Data Management or similar (may vary slightly depending on the exact DD OS version).

Select Space Reclamation: Within Data Management, find and select Space Reclamation settings.

Set Schedule:

Click on Schedule and choose to add a new schedule if not already present.

Set the Day to Monday.

Set the Time to 4:00 AM.

Configure Resource Limit:

Look for an option to limit the resource usage for the reclamation task.

Set the Maximum System Resource Usage (or a similarly named option) to 25% to avoid impacting the system performance excessively.

Save the Schedule: Confirm and save your settings.

Verify the Schedule: Check that the schedule appears correctly in the list, indicating it will run every Monday at 4:00 AM with the specified resource usage limit.

After completing these steps, the PowerProtect DD system should reclaim space as scheduled without exceeding 25% resource usage, minimizing its impact on other system operations.


Question 3

Which best practice should be followed when implementing a PowerProtect DD VTL?



Answer : B

Best practice for implementing a DD VTL suggests limiting the number of virtual tapes initially and expanding as needed. This approach minimizes management complexity and ensures that resources are allocated efficiently.


Question 4

What is the maximum number of ES40 SAS shelves that can be added to a PowerProtect DD system with an existing DS60 shelf?



Answer : C

When a DS60 shelf is already part of the configuration, a maximum of 5 ES40 SAS shelves can be added to maintain balance and prevent overloading the system's data handling capabilities. This limit ensures optimal performance and reliability.


Question 5

Which fabric zoning configuration is recommended by Dell Technologies for implementing a DD VTL?



Answer : D

The best practice for fabric zoning with PowerProtect DD Virtual Tape Library (VTL) is single initiator-single target zoning. This configuration minimizes cross-talk and reduces risks of interference, resulting in a more stable and secure data transfer environment.


Question 6

A customer's PowerProtect DD system is full. No data can be written or deleted from the system. Which two actions can the customer take to make capacity available on the system? (Select 2)



Answer : C, D

Expiring snapshots and initiating file system cleaning are effective ways to free up space on a full PowerProtect DD system. These actions help reclaim storage by removing old, unneeded data without impacting active backups. When a PowerProtect DD system is full and no further data can be written or deleted, the following actions can be taken to free up space:

Expire Existing Snapshots: This process involves removing old or expired snapshots that are no longer needed, which helps in reclaiming space within the system.

Start File System Cleaning: File system cleaning is a maintenance operation that reclaims unused space by consolidating and removing data that is no longer needed, such as expired or deleted data segments. This process is essential in freeing up capacity when the system is near or at full utilization.

These steps allow administrators to make space available on the system without immediately adding new storage or altering the configuration.


Question 7

Which systems support the FS25 enclosure?



Answer : D

The FS25 enclosure is compatible with DD9900, DD6900, and DD9400, providing additional storage capacity and performance capabilities tailored for high-demand PowerProtect DD deployments.
