Just the same as the free demo, we have provided three kinds of versions of our COH-285 preparation exam, among which the PDF version is the most popular one. It is understandable that many people give their priority to use paper-based COH-285 Materials rather than learning on computers, and it is quite clear that the PDF version is convenient for our customers to read and print the contents in our COH-285 study guide.

NEW QUESTION # 55
A backup job configured with a retention level of 2 and "Policy volume pool" set to "server_tapes" is failing due to status code 96: Unable to allocate new media for backup. See the output of the available_media command below.
Which task in the NetBackup Administration Console should the administrator perform to resolve the status code 96 error?
Answer: A
Explanation:
The correct action is to move E02003 to the scratch_pool. Cohesity NetBackup documentation states that the Policy volume pool specifies the default media pool for policy backups, and whenever a new volume is required, NetBackup allocates it from that indicated pool. It also identifies the scratch volume pool as the mechanism that lets NetBackup automatically transfer volumes when another pool has no media available. In the output, the policy requires server_tapes, but that pool has no usable available HCART2 media: E02007 and E02008 are active with retention levels 1 and 3, E02005 is full, E02006 is frozen, and E02004 is FULL
/FROZEN. Unfreezing E02004 would not solve the issue because it remains full. NetBackup also stores tape backups with other backups at the same retention level by default, so this retention-level mismatch matters for active tapes. E02003 is the only unassigned, available HCART2 backup tape. Placing it in the scratch pool allows NetBackup to move it automatically into server_tapes when the job requests new media. References

What can be tuned in NetBackup using the data buffer parameters?
Answer: A
NEW QUESTION # 58
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.
NEW QUESTION # 59
How are install packages for a deployment policy execution obtained?
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
