NEW QUESTION # 13
A customer needs to perform a Virtual Machine Recovery from a save set located on a Dell EMC Cloud Tier.
Which additional device type must be available to perform this recovery?
- A. PowerProtect DD
- B. AFTD
- C. PowerProtect Storage Direct
- D. CloudBoost
Answer: A
Explanation:
A customer needs to have a PowerProtect Storage Direct available to perform a Virtual Machine Recovery from a save set located on a Dell EMC Cloud Tier. PowerProtect Storage Direct is a feature that allows the user to mount a cloud-based object store, like Amazon S3, Azure Blob, or Dell EMC Cloud Tier, as a local mount point. This mount point can be used to perform a recovery, like a Virtual Machine recovery, from a save set that is located on a cloud-based object store.
AFTD, PowerProtect DD, and CloudBoost are different device types, AFTD is a feature that allows the user to create a backup copy of a save set to a different location, PowerProtect DD is a deduplication storage appliance and CloudBoost is a feature that allows the user to perform backups and recoveries to and from a cloud-based object store.
It's worth mentioning that for more information about PowerProtect Storage Direct and the supported cloud-based object stores, you can check the official Dell EMC documentation: PowerProtect Data Manager Cloud Tier (https://www.dellemc.com/en-us/storage/powerprotect-data-manager/features/cloud-tier.htm)

NEW QUESTION # 26
An administrator wants to make sure Oracle backups only use a specific storage node.
Use the simulator to configure an AFTD Device on "StorageNodeA" with the name "OracleBackup" using the folder "D \AFTD" to the pool "Default". This storage node should be a dedicated storage node
When you have finished, continue to the next question.
Answer:
Explanation:
To configure an AFTD device on "StorageNodeA" with the name "OracleBackup" using the folder "D:\AFTD" to the pool "Default", the administrator can use the Data Domain CLI (Command Line Interface) to access the Data Domain system and create the AFTD device. Here are the steps:
Log in to the Data Domain CLI by entering the following command:
ssh admin@StorageNodeA
Once logged in, create a new AFTD device named "OracleBackup" by entering the following command:
ddboost afd create --name OracleBackup --pool Default --folder D:\AFTD
Verify that the new AFTD device has been created by running the following command:
ddboost afd show --name OracleBackup
To make sure that the Oracle backups only use the specific storage node, you can assign the AFTD device to the Oracle backup host by running the following command:
ddboost afd set --name OracleBackup --host OracleBackupHost
Verify the configuration by running the following command:
ddboost afd show --name OracleBackup
To make sure that the StorageNodeA is a dedicated storage node, you can configure the storage node to only allow the OracleBackup host to use the AFTD device by running the following command:
ddboost host access add --host OracleBackupHost --afd OracleBackup
Finally, the administrator should select the "Apply" button to save the configuration.

- B. PSS:stream_ss=3,/data1; 5,/data2
- C. PSS:streams_per_ss=3,/data1: streams_per_ss=5,/data
- D. PSS:streams_per_ss=3,/data1, 5,/data2
Answer: D
Explanation:
To configure PSS for a client to have 3 PSS for save set '/data1' and 5 PSS for save set '/data2', the administrator can use the following command:
PSS:streams_per_ss=3,/data1, 5,/data2
This command sets the number of parallel save streams (PSS) for each save set. The option "streams_per_ss" is used to specify the number of parallel save streams for each save set, and the path of the save set is specified after a comma. In this case, 3 PSS are set for the save set '/data1' and 5 PSS are set for the save set '/data2'.
