Which command is used to remove media from an automated tape library?

  1. UNLOAD LIBVOL
  2. CHECKOUT LIBVOL
  3. EJECT LIBVOL
  4. REMOVE LIBVOL

Answer(s): B

Explanation:

According to IBM's documentation1, the CHECKOUT LIBVOL command is used to remove a sequential access storage volume from the server inventory for an automated library. This command creates a background process that can be canceled with the CANCEL PROCESS command.

Which two items should be examined for optimal performance prior to implementing server-side deduplication on a large IBM Spectrum Protect server?

  1. the server option DEDUPRQUIRESBACKUP no has been specified
  2. the optimal deduplication algorithm has been selected
  3. the storage for the database provides sufficient IOPS
  4. the server has sufficient memory
  5. the available LAN bandwidth is adequate

Answer(s): C,D

Explanation:

According to the IBM Spectrum Protect documentation1, server-side deduplication is a process that eliminates duplicate data blocks on the server during backup operations.

Therefore, two items that should be examined for optimal performance prior to implementing server-side deduplication on a large IBM Spectrum Protect server are:

the storage for the database provides sufficient IOPS. Use a high-performance disk for the IBM Spectrum Protect database. At a minimum, use 10,000 rpm drives for smaller databases that are 200 GB or less1.

the server has sufficient memory. The amount of memory that is required depends on several factors, such as the number of concurrent sessions, the size of data blocks, and the deduplication ratio1.



How can an administrator be designated as an approval administrator?

  1. update the admin with the CMDAPPROVER=YES option
  2. update the list of the admins in the set COMMANDAPPROVAL command
  3. issue the command SET APPROVERSREQUIREAPPROVAL=ALL
  4. issue the command GRANT APPROVERSANDMINS=ALL

Answer(s): C,D

Explanation:

According to IBM's documentation1, server-side deduplication is the process of removing redundant data during a backup operation on the server system. Server-side deduplication is especially effective when you want to conserve disk space on the server storage pools.

To optimize the performance of server-side deduplication, two items that should be examined are:

The storage for the database provides sufficient IOPS. IBM recommends using a high-performance disk for the database and ensuring that it has a minimum capability of 3000 IOPS1.

The server has sufficient memory. IBM recommends allocating at least 1 GB of memory for each TB of data that is backed up each day2.



A department has a business requirement that all their backups are encrypted to prevent data from being read during the transmission to the server and also once written in the storage pool.
Which encrypted method satisfies all those requirements?

  1. client-side encryption
  2. SSL encrypted communication
  3. tape drive encryption
  4. server-side encryption

Answer(s): A

Explanation:

According to IBM's documentation12, client-side encryption is a method of encrypting data before it is sent to the server for backup or archive operations. Client-side encryption uses a password that is entered by the user to generate an encryption key. The password needs to be confirmed when encrypting the file for backup, and also needs to be entered when performing restores of encrypted files12.

Client-side encryption satisfies all the requirements of encrypting data during transmission and storage, because:

It prevents data from being read during transmission, because the data is encrypted before it leaves the client system3.

It prevents data from being read once written in the storage pool, because the data remains encrypted on the server and can only be decrypted with the password that is known by the user3.
