최신 Cohesity Protection Professional COH-285 무료샘플문제 (Q74-Q79):

질문 # 74
The primary server catalog is being recovered to a new server. The administrator receives the message displayed below:
"Please insert the following media and run the volume configuration wizard or the vmupdate command to update the NetBackup database.
Host - train1
MediaID - GBP847
Barcode - GBP847S1"
In the NetBackup Administration Console, barcode GBP847S1 is associated with media ID P847S1.
How should the administrator proceed?

정답：D

설명：
The correct procedure is to delete the incorrectly discovered tape entry, configure the Media ID generation rule correctly, re-inventory the library, and then run the recovery. The catalog recovery request requires MediaID GBP847 for barcode GBP847S1, but the new server inventoried the tape as P847S1. Cohesity NetBackup documentation explains that, by default, NetBackup generates a media ID from the last six characters of a tape barcode. For barcode GBP847S1, the last six characters are P847S1, which exactly matches the incorrect media ID shown in the Administration Console. Cohesity further states that media ID generation rules override this default and define which barcode characters NetBackup uses to create the media ID. In this case, the rule must generate the media ID from the first six characters, producing GBP847. The rule is configured from the robot inventory advanced options under Media ID Generation. A barcode rule is not sufficient because barcode rules assign media attributes such as media type or volume pool, whereas media ID generation controls the actual media ID. bplabel is also inappropriate because it can relabel media and risks invalidating existing backup data. References/topics: Catalog recovery, robot inventory, media ID generation rules, and tape barcode handling.


질문 # 75
A backup job fails with the status code of 96. To troubleshoot the failure, the administrator wants to view the application log files written by the NetBackup Resource Broker.
Which command should the administrator run to find the date, time and actual message text from the log file?

정답：C

설명：
The correct command is vxlogview -o 118 -d D,T,x. Status code 96 commonly indicates that NetBackup could not allocate required media or storage resources, so troubleshooting should focus on the NetBackup Resource Broker, also known as nbrb. Cohesity NetBackup documentation identifies originator ID 118 as nbrb, the NetBackup Resource Broker, which maintains available resource information and locates the physical and logical resources needed for backup and tape restore operations. The vxlogview command is the supported utility for reading unified logs, because unified log files are binary and must be assembled by vxlogview. The -o 118 option filters log records for the Resource Broker originator, while -d D,T,x displays the required fields: date, timestamp, and actual log message text. The command reference defines D as display date, T as display timestamp, and x as display actual log message text. Option C is incorrect because w displays who logged diagnostic/debug messages, not the actual message text. References/topics: NetBackup unified logging, vxlogview, originator IDs, nbrb Resource Broker logging, and status 96 resource allocation troubleshooting.


질문 # 76
Which feature is compatible with the NBU-Catalog policy type?

정답：C


질문 # 77
What is the name of the command that lets you expire a backup image manually in NetBackup?

정답：C


질문 # 78
An administrator has two offices in different cities with Auto Image Replication (AIR) implemented to replicate the backups from one office location to the other location using Storage Lifecycle Policy (SLP).
Multiple small servers are backed up daily, which results in many replication jobs in the environment. The Storage Lifecycle Policy (SLP) parameters are:
* SLP.MIN_SIZE_PER_REPLICATION_JOB = 20GB
* SLP.MAX_TIME_TIL_FORCE_SMALL_REPLICATION_JOB = 60 MINUTES
After modifying the SLP parameters, three backup jobs are completed and the size of each backup job is 5GB.
A backup window has closed, and no new backup jobs will occur.
When does the next replication job start?

정답：A

설명：
The replication job starts when the force interval for small replication jobs is reached. NetBackup SLP settings control how Storage Lifecycle Policy jobs are maintained and executed for the selected primary server. Cohesity documentation identifies these as SLP settings used to customize how SLP jobs run. For AIR replication batching, the controlling parameter here is SLP.MIN_SIZE_PER_REPLICATION_JOB. Official NetBackup documentation defines it as the smallest batch size that can run as a single replication job and states that the job does not run until enough images accumulate to reach that size, or until the force interval for small replication jobs is reached. (veritas.com) In this scenario, three backups of 5GB each create only 15GB of eligible replication data. That is below the configured 20GB threshold, so NetBackup does not start the replication job based on size. Because the backup window has closed and no additional backup images will arrive, the batch cannot reach 20GB. NetBackup therefore submits the small replication batch when the oldest image reaches the configured 60-minute force interval. The force interval is specifically designed to prevent NetBackup from waiting too long before submitting a small replication job. (veritas.com)
