問題 #200
Refer to the Exhibit.
An administrator is trying to access client properties on the NetBackup Administration Console and receives the following message:

When checking the services on the master server, the administrator sees that the PBX service is down.
Which two commands can the administrator use to increase the PBX log level to determine the reason for the message above? (Choose two.)

答案：B,C


問題 #201
Which schedule can be configured as a synthetic backup in addition to the full backup schedule type?

答案：D

解題說明：
The correct answer is Cumulative incremental backup. In NetBackup policy schedule configuration, the Synthetic backup schedule attribute is not limited only to a Full schedule. Cohesity documentation states that the Synthetic backup attribute allows a backup image to be assembled from prior backup images and that "a synthetic backup may be a synthetic full or a synthetic cumulative incremental backup." This directly identifies cumulative incremental as the additional schedule type that can be configured as synthetic.
Differential incremental backups are normally used as component images that feed the synthetic operation; they capture changed data and are later consolidated, but they are not the synthetic schedule type in this question. User archive and Vault catalog backup schedules are unrelated to synthetic backup image construction. Cohesity also explains that a synthetic cumulative incremental backup is produced by consolidating component images, including differential incremental backups taken since the last cumulative backup and, when available, the last cumulative incremental backup. Therefore, besides Full, the schedule type that supports synthetic configuration is Cumulative incremental backup. References/topics: Synthetic backup schedule attribute, Synthetic cumulative incremental backups, and Schedules required for synthetic backups.


問題 #202
An administrator has a scheduled policy that backs up 20 clients, each with multiple mount points and multiple data streams enabled. One of the jobs has failed and is in an Incomplete state in the Activity Monitor.
How should the administrator verify the incomplete job runs prior to the next scheduled backup?

答案：A

解題說明：
The correct action is to resume the job from Activity Monitor. Cohesity NetBackup documentation states that Activity Monitor provides a Resume action for jobs that are suspended or in an Incomplete state; the documented procedure is to open Activity Monitor > Jobs, select the incomplete job, and choose Actions > Resume Job. This is the supported way to make the same incomplete backup continue before the next scheduled backup starts. It is especially important in a multiple data streams policy, where each stream appears as an individual job and the failed stream should be resumed rather than replaced by a new manual backup. The Move backup job from incomplete state to done state property only controls how long a failed backup can remain incomplete before Activity Monitor shows it as Done; reducing that value would shorten the recovery window, not rerun the backup. Cohesity also notes that a resumed job reuses the same job ID, whereas a restarted job receives a new job ID. Running a manual client or mount-point backup would create a separate backup operation and would not verify completion of the existing incomplete job. References/topics:
Activity Monitor job actions, Resume incomplete jobs, Checkpoint restart, and Clean-up host properties.


問題 #203
What can be tuned in NetBackup using the backup policies?

答案：B


問題 #204
Refer to the exhibit.

Two media servers, sharing a library with 6 tape drives, exist in the NetBackup environment displayed in the exhibit. Both weekly Full and daily Differential Incremental backups need to run for the clients and each schedule has a different retention period. Because of network topology, some clients back up to Media server 1 and some back up to Media server 2. The environment suffers from multiple status 96 failures during the backup window.
How can the administrator minimize the number of failures?

答案：B


問題 #205
