最新的 Cohesity Protection Professional COH-285 免費考試真題 (Q59-Q64):

問題 #59
Which of the following specialized backup solutions is used to reduce backup time and network bandwidth by backing up only the changed blocks of data between successive full backups?

答案：D


問題 #60
An administrator has an environment that runs over one thousand jobs a night. Some nights, there are hundreds of jobs queued waiting for a resource.
Which action should the administrator take in the event that specific queued jobs need to run when a resource next becomes available during that evening's backup session?

答案：C

解題說明：
The correct action is to increment the job priority in Activity Monitor for the specific queued job. Cohesity NetBackup documentation states that an administrator can dynamically change the priority of selected queued or active jobs that wait for resources directly from the Activity Monitor by selecting the job and choosing Change Job Priority. The available options include setting a specific priority, incrementing the job priority, or decrementing it, and the change affects only the selected job rather than all jobs of that type. This matches the requirement: a small subset of queued jobs must be favored during the same backup session, without changing long-term policy behavior.
Changing the priority in the policy is less appropriate because the policy attribute defines how that policy competes with other policies for resources, and is a configuration-level setting rather than an immediate per- job intervention. NetBackup uses job priority as a scheduling guide; higher-priority requests are evaluated before lower-priority requests, although resource optimization can still influence final selection. Therefore, the operationally correct response is option A.


問題 #61
Which guide should be referred to for configuring backup policies in NetBackup 10.1?

答案：D


問題 #62
After creating a NBU-Catalog type backup policy, an administrator receives the following message:
"DR file is on the same partition as your catalog and will be unusable in an actual disaster or disk failure." Which two options are available to the administrator to ensure the DR file is available for future use? (Select two.)

答案：B,C

解題說明：
The correct options are A and E. The warning indicates that the catalog disaster recovery file is being written to a location that would likely be lost with the NetBackup catalog during a disk or server failure. Cohesity NetBackup documentation for the NBU-Catalog policy's Disaster Recovery tab states that the DR path is where disaster recovery information is saved, and explicitly recommends not saving that information to the local computer; instead, it should be saved to a network share or removable device. It also states that, on UNIX, the path cannot be on the same partition as /usr/openv/netbackup; it must be changed to a directory on a different partition. Therefore, placing the DR file on a volume other than the NetBackup volume resolves the warning. Cohesity also documents the Send disaster recovery email option, where one or more administrator email addresses can be entered so NetBackup sends DR information after every catalog backup.
The disaster recovery email includes recovery instructions and the image file/package attachments needed for catalog recovery. References/topics: NBU-Catalog policy, Disaster Recovery tab, DR file path, and disaster recovery email configuration.


問題 #63
What is the name of the command that lets you test the connectivity between primary, media, and client servers in NetBackup?

答案：D


問題 #64
