C9060-509 Online Practice Questions and Answers

Correct Answer: B

Explanation: When you configure client-side data deduplication, the following requirements must be met:

*

The client and server must be at version 6.2.0 or later.

*

(not D) Client-side deduplication cannot be used in combination with LAN-free backups.

*

(not C) Files that are intended for deduplication must not be encrypted. Encrypted files and files from

encrypted file systems cannot be deduplicated.

Etc.

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: 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: B

Explanation: RECLAIM STGPOOL (Reclaim sequential-access storage pool) Use this command to reclaim volumes in a sequential-access storage pool. Reclamation makes the fragmented space on volumes usable again by moving any remaining files from one volume to another volume. This makes the original volume available for reuse. Reclamation will not move inactive versions of backup data from volumes in active-data pools.

Correct Answer: B

Explanation: Snapshot database backups are typically used for off-site disaster recovery purposes.

Note: When the client backups are complete, the new data in the primary storage pools should be copied to a copy storage pool. The copy storage pool tapes, along with the database backup tapes, should be taken to a secure off-site location or vault. The copy storage pool and database backup tapes are referred to collectively as the off-site backups, and will be used to restore your environment in the event of a catastrophic failure or disaster.

Correct Answer: C

Explanation: To use the Web Client to back up and restore files on a remote client system, you must have an administrative user ID with client access authority over the node name for the remote client system.

Correct Answer: B

Explanation: Enable the Tivoli Storage Manager Storage Agent to perform LAN-free Data Movement.

Correct Answer: D

Explanation: You can create your own custom reports using IBM Cognos 8 Business Intelligence, or you can install the Business Intelligence and Reporting Tools (BIRT) software.

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.
