What is the correct sequence to perform Cloud Tier migration?
Explanation:
The correct sequence to perform Cloud Tier migration is as follows:
Copy the active tier data from the existing system to the new system.
Disconnect the cloud storage from the existing system.
Connect the cloud storage to the new system.
Copy the cloud tier metadata from the existing system to the new system.
Commit the migration operation.
Copy Active Tier Data: Start by transferring active tier data from the current system to the new PowerProtect DD system. This step ensures that primary data is accessible on the new appliance. Disconnect Cloud Storage: Once the active tier data is copied, disconnect the cloud storage from the original system to prepare it for reconnection.
Connect Cloud Storage to New System: Attach the cloud storage to the new system. This step transitions cloud storage access from the old to the new appliance, preparing it for continued operations.
Copy Cloud Tier Metadata: Metadata associated with the cloud tier is copied to the new system, ensuring continuity of data access and management in the cloud tier.
Commit Migration Operation: Finally, complete the migration process by committing the changes, solidifying the new system as the primary appliance for both active and cloud tier operations. This ordered approach ensures a structured and reliable migration process, maintaining data integrity and continuity across PowerProtect DD systems.
What is a requirement to use the PowerProtect DD HA feature?
- A . Each head unit requires its own FS25 shelf
- B . Head units and nodes require an active/active configuration
- C . A single set of shared storage
- D . Dual set of shared storage configuration
Two companies recently merged. They are consolidating and purchased three PowerProtect DD systems and Avamar protection software.
* One company is using ECS, Google Cloud and Salesforce cloud providers.
* The other is using Alibaba, IBM and Microsoft Azure cloud providers.
What is the maximum number of Cloud Tiers that can be created across the three PowerProtect DD systems by the Administrator?
- A . 3
- B . 4
- C . 6
- D . 5
C
Explanation:
Each PowerProtect DD system can support up to two Cloud Tiers. Therefore, with three PowerProtect DD systems, the maximum number of Cloud Tiers is calculated as follows:
2 Cloud Tiers per PowerProtect DD system × 3 PowerProtect DD systems = 6 Cloud Tiers total.
This configuration allows the administrator to utilize multiple cloud providers efficiently across the consolidated PowerProtect DD systems.
What is the maximum number of snapshots per MTree that can be stored on a PowerProtect DD?
- A . 100
- B . 32
- C . 128
- D . 75
A backup administrator needs to add capacity to a file system. After the installation of an ES40, they need to verify the total amount of data stored before data reduction.
Which command would be used to verify this information?
- A . filesys status
- B . filesys show summary
- C . enclosure show summary
- D . filesys show space
An administrator is scaling Cloud Tier for a DD9900 by adding a second cloud unit.
What is the required amount of metadata storage (TB)?
- A . 120
- B . 240
- C . 300
- D . 500
What is the order of steps to configure DD Boost on a PowerProtect DD appliance?
A customer has a backup environment consisting of a server, media server and clients.
Which two statements are true concerning the media server connected to a PowerProtect DD? (Choose two.)
- A . The backup server and media server functions can be performed on a single system.
- B . The media server schedules, manages, and operates data backup processes on a backup client.
- C . The media server cannot be connected to a PowerProtect DD VTL and active tier.
- D . The media server is used in obtaining and storing backup data.
A, D
Explanation:
The backup server and media server functions can be performed on a single system.: In many environments, it is possible for a single server to act as both the backup server and the media server, simplifying management and resource allocation.
The media server is used in obtaining and storing backup data.: The primary role of the media server is to handle the actual data transfer, manage backup processes, and store backup data, making it essential for an effective backup solution.
What is the data reduction ratio that can be predicted when applying best practices for deduplicating data on a PowerProtect DD?
- A . 45:1
- B . 55:1
- C . 50:1
- D . 65:1
C
Explanation:
The expected data reduction ratio with PowerProtect DD, when following best practices for deduplication, is approximately 50:1. This high deduplication efficiency significantly reduces storage needs, making PowerProtect DD highly cost-effective. When best practices are applied for deduplication on PowerProtect DD systems, a data reduction ratio of 50:1 can typically be achieved. This means that for every 50 units of data, only 1 unit needs to be stored, significantly optimizing storage utilization. Achieving this ratio depends on factors such as data type, backup frequency, and the effectiveness of deduplication processes configured on the system. This high deduplication rate is a key advantage of PowerProtect DD appliances, allowing organizations to manage large volumes of backup data more efficiently.
An administrator notices that several disks on a shelf show as unknown.
What should be done to resolve this issue?
- A . Enter the disk unfail command for the unknown disks
- B . Enter the storage add enclosure command
- C . Ensure the expansion shelf is cabled properly
- D . Cycle the power on the newly added expansion shelf
