Cohesity Certified Protection Professional - NetBackup Appliances Sample Questions (Q135-Q140):

NEW QUESTION # 135
Which of the following is NOT a best practice for securing NetBackup appliances?

Answer: A


NEW QUESTION # 136
Which servers are listed when selecting the client package during the creation of a new deployment policy?

Answer: B


NEW QUESTION # 137
Which two options are available to an administrator to bring the MSDP catalog back online in the case of a hardware problem that caused corruption? (Select two.)

Answer: A,E

Explanation:
The correct recovery options are recovering the MSDP catalog from an MSDP catalog backup and restoring the MSDP catalog from an MSDP catalog shadow copy. Cohesity documentation explains that the NetBackup Deduplication Manager automatically creates daily MSDP catalog shadow copies and transaction logs. If corruption is detected, the Deduplication Manager restores the catalog from the most recent shadow copy and replays the transaction log so the recovered catalog is current. Cohesity also states that administrators should protect the MSDP catalog with a dedicated MSDP catalog backup policy, because a NetBackup catalog backup does not include the MSDP catalog. The MSDP catalog backup is the second tier of protection and is used when shadow copies are unavailable or corrupt. The official recovery guidance identifies the two MSDP catalog recovery options as Restore from a shadow copy and Recover from a backup, specifically noting that a hardware problem can cause complete loss of the MSDP catalog and shadow copies. Options C and D are not the documented standard recovery choices for bringing the MSDP catalog online, and option E is incorrect because the NetBackup catalog backup excludes the MSDP catalog. References/topics: MSDP shadow catalog, MSDP catalog backup policy, Recovering the MSDP catalog, and drcontrol-based catalog protection.


NEW QUESTION # 138
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: B

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.
