Cohesity Certified Protection Professional - NetBackup Appliances Sample Questions (Q84-Q89):

NEW QUESTION # 84
What are the two types of encryption that NetBackup supports for backup data?

Answer: A


NEW QUESTION # 85
How can you manage NetBackup disk and cloud storage?

Answer: A,C


NEW QUESTION # 86
An administrator is attempting to start NetBackup services on a primary server without success. When verifying the database is up using the nbdb_ping command, the administrator receives the following error:
"Database [NBDB] is not available"
Which log file should the administrator analyze to determine why NetBackup Database fails to start?

Answer: C

Explanation:
The correct log to analyze is the nbdb log. The nbdb_ping utility is specifically used to check and display the status of the NetBackup database, including NBDB, NBAZDB, and BMRDB. Cohesity's NetBackup Commands Reference states that running nbdb_ping with no options displays the status of NBDB, which directly matches the diagnostic command in the question. When nbdb_ping reports "Database [NBDB] is not available," the most relevant NetBackup diagnostic logging is produced under the nbdb log area, not emm.log or nbrb-style service logs. Official NetBackup support examples show the same failure being diagnosed from the nbdb log at /usr/openv/netbackup/logs/nbdb, including entries from nbdb_ping, configuration-file read failures, and the exact message Database [NBDB] is not available. Another NetBackup case with the same nbdb_ping error shows server.log containing no useful errors while /usr/openv/netbackup/logs/nbdb contains the actionable nbdb_admin and nbdb_ping failures. Therefore, the log identified by option A is the appropriate troubleshooting source.


NEW QUESTION # 87
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?

Answer: D

Explanation:
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.


NEW QUESTION # 88
A NetBackup policy containing five (5) servers, each with three (3) local drives, is launched in an environment with the NetBackup settings listed below:
Disk Pool Settings: Maximum I/O Streams = 20
Storage Unit Settings: Maximum concurrent jobs = 15
Policy Settings: Multiple Data Streams = Enabled
Backup Selection List = ALL_LOCAL_DRIVES
All other settings remain at their default values. Ten (10) client restores are launched immediately after the backup policy executes.
Excluding parent jobs, how many jobs will be concurrently active?

Answer: D

Explanation:
With ALL_LOCAL_DRIVES and Allow multiple data streams enabled, NetBackup can split each client backup into separate streams per drive or file system; Cohesity documentation states that NetBackup backs up the client and "splits the data from each drive" into its own stream when multiple data streams are enabled.
However, the number of streams that can run concurrently is still constrained by job limits. Cohesity's policy documentation states that concurrent stream count is affected by Maximum jobs per client, Limit jobs per policy, and related storage limits; when Maximum data streams is not explicitly set, NetBackup uses the lower of Maximum jobs per client or Limit jobs per policy. The default Maximum jobs per client is one job, so only one backup stream per client can run. With five clients, that means 5 active backup jobs, not 15.
The storage unit's Maximum concurrent jobs = 15 does not restrict restores, because Cohesity states this setting controls backup and duplication traffic, not restore jobs. The disk pool's Maximum I/O Streams = 20 limits read and write streams; restores read backup images and backups write them. Five backups plus ten restores equals 15 total streams, so all 10 restores can run.
