Cohesity Certified Protection Professional - NetBackup Appliances COH-285 Prüfungsfragen mit Lösungen (Q246-Q251):

246. Frage
Which command should an administrator use to view the available packages in the VxUpdate package repository?

Antwort: B


247. Frage
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.)

Antwort: B,E

Begründung:
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.


248. Frage
An administrator has a MS-Windows type policy that has failed for a Microsoft Windows NetBackup client.
The policy uses the ALL_LOCAL_DRIVES backup selection. See the extract from the end of the job details below.
Which two logs will provide the most relevant information for troubleshooting and resolving the error?
(Select two.)

Antwort: A,E

Begründung:
The correct logs are the NetBackup bpfis logs on the client and the operating system logs on the client. The job details show a Windows snapshot failure: GLOBALROOT\Device\HarddiskVolumeShadowCopy..., status: 156: snapshot error encountered, and status: 1542: An existing snapshot is no longer valid. In Cohesity NetBackup snapshot processing, bpbrm starts bpfis on the client, and bpfis creates the snapshot of the client data and returns snapshot completion status. Therefore, the bpfis client log is the primary NetBackup log for the snapshot creation, mount, and delete phases.
Because this is a Microsoft Windows client snapshot issue, the Windows operating system logs are equally important. Cohesity's status 156 troubleshooting topic identifies VSS framework failures and notes that VSS- related application events may be written on the affected Windows system; it also references bpfis log content for snapshot failures. The media server bpbrm log can show orchestration status, but it usually reports what the client-side snapshot component returned. The bptm log is for media/data movement and is not the best source for VSS snapshot root cause.


249. Frage
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?

Antwort: C


250. Frage
A NetBackup client is reporting an error with the message "Unable to connect to the NetBackup server". What could be the cause of this error?

Antwort: A
