Question 1

Which supported step should an administrator perform to ensure all operating system logs are sent from an appliance to a central logging server running Linux?



Answer : A


Question 2

An administrator wants to back up a large file system with millions of files using either the NetBackup Accelerator feature or the NetBackup FlashBackup feature.

Which consideration is irrelevant when determining which feature to be used?



Answer : B

The irrelevant consideration is the file system folder depth. When selecting between NetBackup Accelerator and NetBackup FlashBackup for a file system containing millions of files, the key design factors are capacity, file-count/metadata handling, change processing, policy support, and file system/platform compatibility---not how deeply folders are nested. Cohesity documents that Accelerator performs an initial full backup and creates a track log, then identifies changed data by comparing track-log information against file-system information for each file; on NTFS/ReFS it can also use the Windows change journal. Cohesity also states that Accelerator track-log sizing is relative to file system size and number of backup files, with sizing formulas based on number of files and used disk space---not directory depth. FlashBackup is documented as combining raw-partition backup speed with individual file restore, and the FlashBackup/FlashBackup-Windows policy types are platform-specific, making the type of file system/client platform relevant. Storage capacity is also relevant because FlashBackup size reporting uses the mounted Windows disk volume or UNIX raw disk partition size. Reference/topics: Accelerator operation, track-log sizing, FlashBackup policy types, and large file-system backup planning.


Question 3

How are install packages for a deployment policy execution obtained?



Answer : A

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. Reference/topics: Deployment Management, VxUpdate, Package Repository, and nbrepo repository management.


Question 4

An administrator took media server mediaA offline for maintenance and set up a new media server mediaB with access to the previously backed up data. When restores are performed for data that was backed up by mediaA, the restores fail.

Which setting must the administrator modify to allow successful restores?



Answer : D


Question 5

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?



Answer : C


Question 6

What is the name of the feature that allows NetBackup to deduplicate data across multiple domains or sites using optimized duplication?



Answer : A


Question 7

Where can an administrator change a disk pool to Down status in the NetBackup Administration Console?



Answer : B

The correct location is Media and Device Management > Device Monitor > Disk Pools. In NetBackup, the Devices > Disk Pools view is primarily used to view configured disk pools, manage disk-pool properties, delete disk pools, or perform inventory-related actions. It is not the operational monitoring location used to change the runtime state of a disk pool. Cohesity documentation distinguishes the disk-pool management view from state monitoring; for example, it states that disk pool state is UP or DOWN and that the state is displayed in the Status column when locating the disk pool. The classic NetBackup Administration Console procedure states that to change disk pool state, the administrator selects Media and Device Management > Device Monitor, opens the Disk Pools tab, selects the disk pool, and then chooses Actions > Up or Actions > Down. Cohesity's disk-pool state guidance also notes that changing a disk pool to DOWN requires the disk pool not to be busy; assigned backup jobs must complete or be canceled before the state change succeeds. Therefore, the correct console path is option B.
