NEW QUESTION # 114
How are install packages for a deployment policy execution obtained?
- A. They are downloaded from the Veritas support site when the policy is launched.
- B. They must be manually copied to the clients before the policy can be launched.
- C. They must be manually added to the primary server repository before the policy can be launched.
- D. They must be manually added to a repository that is external to the NetBackup environment prior to launching the policy.
Answer: C
Explanation:
The correct answer is A. NetBackup deployment policies use VxUpdate, and VxUpdate relies on the NetBackup package repository located on the primary server. Cohesity documentation states that "VxUpdate uses a repository that resides on the primary server" and that the repository contains the packages that can be deployed to media servers and clients. It also explains that the packages referenced by deployment policies are verified and installed into that repository before use. In the deployment policy workflow, the administrator selects a package from the policy's Package drop-down list; therefore, the package must already exist in the repository before the policy can run successfully. Cohesity explicitly notes that packages must be added to the VxUpdate repository before creating a working deployment policy, and policies without packages in the repository fail when run. Packages are not manually copied to every client, are not maintained in an external repository, and are not downloaded automatically from support at launch time. The administrator downloads or obtains the appropriate signed VxUpdate package, then adds it using the web UI or nbrepo -a. References

NEW QUESTION # 116
An administrator is experiencing a communication issue between the master and client and believes the certificate might be revoked.
Which log can the administrator view to analyze a certificate issue?
- A. bprd
- B. vnetd proxy
- C. nbemm
- D. nbrb
Answer: B
Explanation:
The correct log is the vnetd proxy log. NetBackup secure host communication uses host ID-based certificates and certificate revocation lists (CRLs). When communication fails between the primary/master server and a client because a certificate is revoked, unavailable, missing, or affected by CRL validation, the relevant troubleshooting path is the vnetd proxy process log files. Cohesity's NetBackup Troubleshooting Guide states that for host-certificate troubleshooting, administrators should examine job details for certificate, revocation, and CRL messages, and "may need to examine the vnetd proxy process log files" for related messages and status codes. The same guide notes that NetBackup hosts must have a valid host ID-based security certificate and a valid CRL to communicate; otherwise, communication fails. For a revoked primary server certificate, Cohesity specifically identifies that the vnetd proxy process log files on hosts show that the primary server certificate is revoked. Therefore, nbemm is for Enterprise Media Manager functions, bprd is request processing, and nbrb is resource brokering; none is the primary diagnostic log for certificate revocation analysis. Reference topics: Troubleshooting security certificate revocation, Viewing vnetd proxy log files, and Test the vnetd proxy connections.

NEW QUESTION # 122
Which backup storage is unsupported with media server load balancing?
- A. Media Manager storage
- B. AdvancedDisk
- C. Media Server Deduplication Pool
- D. BasicDisk
Answer: D
Explanation:
The unsupported backup storage is BasicDisk. In NetBackup, Media server load balancing is a storage unit group selection method that directs jobs based on a capacity-managed approach, helping NetBackup avoid sending backup work to overloaded media servers. Cohesity NetBackup documentation states that NetBackup evaluates factors such as media server rank, current job count, and available disk space before selecting the most suitable storage unit. Most importantly, the same official topic explicitly states that Media server load balancing cannot be selected for a storage unit group that includes a BasicDisk storage unit, and a BasicDisk storage unit cannot be added to an existing group where Media server load balancing is already enabled.
This makes option C correct. AdvancedDisk, MSDP, and Media Manager storage are valid NetBackup storage technologies used in storage unit group designs, though the recommended selection method can vary by storage type. Cohesity documentation notes that Failover is recommended for AdvancedDisk, MSDP, and OpenStorage, while Media server load balancing remains a selectable storage unit group method for supported configurations. Reference topics: Configuring storage unit groups, Storage unit selection criteria within a group, and Media server load balancing.

NEW QUESTION # 124
An administrator has a backup for client Linux1 using the LinuxClients policy complete successfully. Even though the policy Backup Selections are NOT modified, the backup job fails the next day with the following status code:
Error 71: none of the files in the file list exist.

- A. The client was temporarily shut down.
- B. The file systems have been unmounted on the client.

NEW QUESTION # 125
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?
- A. 15 backup jobs, 10 restore jobs
- B. 15 backup jobs, 5 restore jobs
- C. 5 backup jobs, 10 restore jobs
- D. 10 backup jobs, 10 restore jobs
Answer: C
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.
