NEW QUESTION # 131
A new storage shelf is added to an existing appliance.
Which command under Manage > Storage must the administrator perform first after a new shelf is connected to the appliance and the appliance is powered on?

• A. Add
• B. Grow
• C. Resize
• D. Scan

Answer: D

Explanation:
The first command is Scan. After a storage shelf is physically connected and the appliance is powered on, the appliance must discover and refresh the newly attached storage hardware before the disks can be added or assigned. The NetBackup Appliance administration procedure states that storage devices are scanned from Main > Manage > Storage, and the administrator should enter the Scan command to scan connected storage devices. It specifically notes that whenever a storage device is connected or disconnected, this command is used to detect the storage device or refresh its status. The scan operation refreshes the storage inventory and, on 53xx appliances, can create new disk/RAID groups on external storage before reporting success. Only after the scan makes the disks visible as New Available should the administrator use Add to add the disks into unallocated storage. Grow and Resize are later capacity-management actions and are not the discovery step.
References/topics: Manage > Storage, Scanning storage devices, Adding newly available disks, and storage shelf expansion workflow.

• B. Optimized duplication requires the media servers to be configured as Fibre Transport media servers.

NEW QUESTION # 135
What is the definition of a Storage Unit?

• A. It is a label that allows the administrator to create a storage plan.
• B. It is a label that NetBackup associates with physical storage.
• C. It is a label that the Media Manager associates with physical storage.
• D. It is a label that defines the physical location of the storage.

Answer: B

Explanation:
A Storage Unit is a logical NetBackup object used to represent the storage destination for backup data. The official Cohesity NetBackup documentation defines it directly: "A storage unit is a label that NetBackup associates with physical storage." It further explains that the label can identify a robot, a path to a volume, or a disk pool. This makes option C the precise definition. Option A is incomplete because a storage unit does not merely define a physical location; it abstracts storage resources so policies and storage lifecycle operations can target them. Option B is incorrect because storage plans or lifecycle policies may use storage units, but a storage unit itself is not created for the sole purpose of creating a plan. Option D is too narrow because Media Manager is associated primarily with tape/robotic media handling, while storage units are broader NetBackup entities and can represent tape, disk, or disk-pool destinations. Cohesity NetBackup storage topics also describe storage units as part of the recognized storage configurations and note that they can be included in storage unit groups or storage lifecycle policies.

NEW QUESTION # 136

NEW QUESTION # 142
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 added to the primary server repository before the policy can be launched.
• C. They must be manually copied to the clients 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: B

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
