C9060-509 Online Practice Questions and Answers

Correct Answer: C

Explanation: If you modify a recalled file, it becomes a resident file. The next time your file system is reconciled, the space monitor daemon marks the stored copy for expiration.

Correct Answer: D

Explanation: The DEDUPREQUIRESBACKUP option specifies whether volumes in primary sequential-access storage pools that are set up for deduplication can be reclaimed and whether duplicate data can be discarded before the storage pools are backed up.

Correct Answer: CD

Explanation: C: File-level backup and restore for NDMP operations When you do a backup via NDMP (network data management protocol), you can specify that the Tivoli Storage Manager server collect and store file-level information in a table of contents (TOC).

If you specify this option at the time of backup, you can later display the table of contents of the backup image. Through the backup-archive Web client, you can select individual files or directories to restore directly from the backup images generated.

D: Snapdiff

Using the snapdiff option with the incremental command streamlines the incremental backup process. The

command runs an incremental backup of the files that were reported as changed by NetApp instead of

scanning all of the volume for changed files

Incorrect:

Not E: SNAPMirror

Specifies that the file system should be copied to a Tivoli Storage Manager storage pool using the NetApp

SnapMirror to Tape function. SnapMirror images are block level full backup images of a file system.

Correct Answer: C

Explanation: The Backup Operators group allows users to back up and restore files regardless of whether they have read or write access to the files. Since this group has a limited set of user rights, some functions are not available to members of the Backup Operators group.

Correct Answer: B

Explanation: The set access command gives users at other nodes access to your backup versions or archived copies. You can give another user access to a specific file, multiple files, or all files in a directory. When you give access to another user, that user can restore or retrieve your objects. Specify in the command whether you are giving access to archives or backups.

Correct Answer: DE

Explanation: * When collocation is by client node Volume selection order: 1st: A volume that already contains files from the same client node

* When collocation is by file space Volume selection order: 1st: A volume that already contains files from the same file space of that client node

Note: With collocation enabled, the server attempts to keep files belonging to a group of client nodes, a single client node, or client file space on a minimal number of sequential- access storage volumes. Collocation reduces the number of volume mounts required when users restore, retrieve, or recall a large number of files from the storage pool. Collocation thus reduces the amount of time required for these operations.

Correct Answer: B

Explanation: * Data deduplication in Tivoli Storage Manager is a two-phase process. In the first phase, the server identifies the duplicate data in the storage pool. As volumes in the storage pool are filled, data becomes eligible for duplicate identification. A volume does not have to be full before duplicate identification starts. In the second phase, duplicate data is removed by any of the following processes:

Reclaiming volumes in the primary-storage pool, copy-storage pool, or active-data pool Backing up a primary-storage pool to a copy-storage pool that is also set up for deduplication Copying active data in the primary-storage pool to an active-data pool that is also set up for deduplication Migrating data from the primary-storage pool to another primary-storage pool that is also set up for deduplication Moving data from the primary-storage pool to a different primary-storage pool that is also set up for deduplication, moving data within the same copy-storage pool, or moving data within the same active-data pool

Correct Answer: C

Explanation: * Access mode:

Defines access to volumes in the storage pool for user operations (such as backup and restore) and

system operations (such as reclamation and server migration).

* Server processes can move files within the volumes in the storage pool.

Correct Answer: D

Explanation: There are two copy groups that can be defined within a management class, the Backup copy group and the Archive copy group. The key difference between the two can be summarized in one word, versions. The backup feature keeps and maintains versions of backup data whereas the archive feature retains a long term copy of data without storing or maintaining versions.

Correct Answer: D

Explanation: The client acceptor daemon serves as an external timer for the scheduler. When the scheduler is started, it queries the server for the next scheduled event. The event is either executed immediately or the scheduler exits. The client acceptor daemon restarts the scheduler when it is time to execute the scheduled event.
