• B. To provide load balancing and failover for backup jobs
• C. To define the physical location of the storage units in the backup environment
• D. To specify the backup schedule for storage units

Answer: B

Explanation:
( Storage unit groups in NetBackup enable load balancing and failover for backup jobs, by allowing you to define multiple storage units for a backup policy and specify the order in which they are used for backups.)

NEW QUESTION # 125

• C. Certificates are deployed with a token for all hosts and the Certificate Revocation List (CRL) is refreshed every 4 hours.
• D. Certificates are deployed automatically for known hosts and the Certificate Revocation List (CRL) is refreshed every hour.

Answer: A

NEW QUESTION # 126

• B. by using the import date plus the original retention
• C. by using the import date plus seven years
• D. by using the original backup date plus infinity

Answer: B

NEW QUESTION # 127

NEW QUESTION # 129
Backup images that reside in an MSDP storage pool have been manually expired using bpexpdate.
Which step must an administrator perform to manually free the associated space in the storage pool?

• A. run image cleanup on the media server that hosts the MSDP storage server
• B. run an inventory on the MSDP storage pool
• C. run content router queue processing on the media server that hosts the MSDP storage server
• D. run content router queue processing on the primary server

Answer: C

Explanation:
The correct action is to run content router queue processing on the media server that hosts the MSDP storage server. In an MSDP environment, expiring backup images with bpexpdate removes or marks the NetBackup catalog references, but the deduplicated segment references in MSDP are reclaimed through the deduplication transaction queue. Cohesity NetBackup documentation explains that after images are expired, MSDP may not immediately reclaim the freed space and that administrators can accelerate reclamation by manually processing the MSDP transaction queue. The deduplication process writes transaction log data into the queue directory, and that queue data is later processed during the next content router queue processing operation.
Official NetBackup Deduplication procedures specify running crcontrol --processqueue on the MSDP storage server, not on the primary server. Image cleanup alone is not the MSDP space-reclamation mechanism after manual expiration, and a storage-pool inventory does not dereference deduplicated fragments. Therefore, the required step is option A.

NEW QUESTION # 130

• B. Defining cloud storage credentials and configuring a cloud storage server
• C. Configuring a storage lifecycle policy and specifying the cloud storage target
• D. Configuring a storage unit group and defining the backup schedule for cloud storage

Answer: B

Explanation:
( To configure cloud storage in NetBackup, you need to define cloud storage credentials and configure a cloud storage server, which involves specifying the cloud storage endpoint, access key, and secret key, among other parameters.)
