Cohesity Certified Protection Professional - NetBackup Appliances 認定 COH-285 試験問題 (Q158-Q163):

質問 # 158
A NetBackup restore job is failing with the message "Unable to find backup file". What could be the cause of this error?

A. The client does not have permission to access the backup file.
B. The backup file is not accessible.
C. The backup file is corrupted.
D. The client is not configured to use the backup file.

正解：B

質問 # 159

A. Cohesity NetBackup Deduplication Guide
B. Cohesity NetBackup AdvancedDisk Storage Solutions Guide
C. Cohesity NetBackup Status Codes Reference Guide
D. NetBackup Web UI Cloud Administrator's Guide

正解：D

質問 # 160
An administrator runs the following command on the primary server to test connectivity to a client:
bptestbpcd -client clientA
The administrator receives the following message:
< 16 > bptestbpcd main: Function ConnectToBPCD (clientA) failed: 25 cannot connect on socket Which two reasons may cause this error message? (Select two.)

A. vnetd is stopped on the primary server.
B. The primary server is unknown to the client.
C. The NetBackup processes on the client are stopped.
D. nbdisco process needs to be running on the client.
E. There is an incorrect entry for the client in the primary server's hosts file.

正解：C、E

解説：
The correct causes are an incorrect client host-name resolution entry on the primary server and stopped NetBackup client processes. The bptestbpcd utility is specifically used to establish a connection from a NetBackup server to the bpcd daemon on a NetBackup host or client, and successful output reports the socket connections that were established. A status 25: cannot connect on socket means the primary server could not complete that socket connection. Official NetBackup troubleshooting guidance states that status 25 commonly results when the client does not acknowledge the TCP connection, the server cannot resolve the client, the client is not listening on bpcd/vnetd, or name resolution fails. Therefore, an incorrect hosts-file entry for clientA on the primary server can send the connection attempt to the wrong address or prevent proper resolution. Likewise, if the NetBackup processes on the client are stopped, the client will not be listening on the required bpcd/vnetd ports. The troubleshooting procedure specifically instructs administrators to verify that the client has bpcd and vnetd ports in listening mode. Options B and E are unrelated to this client-side connection test, while C aligns more closely with authorization failures such as status 59. References/topics:
bptestbpcd, status code 25, client name resolution, and bpcd/vnetd client connectivity troubleshooting.

質問 # 161
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.)

A. ensure the folder DR file is on a non-root volume
B. configure Auto Image Replication to send the DR file to a remote primary server
C. ensure the DR file is created on a volume other than the NetBackup volume
D. configure a valid email address of the administrator in the "Send email" option
E. configure a separate backup policy for DR file backup

正解：C、D

解説：
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.

質問 # 162
How can you manually duplicate a backup image?

A. Use the NetBackup command line to duplicate the image.
B. Use the NetBackup administration console to duplicate the image.
C. Restore the image to a test system and then duplicate it.

正解：B
