IBM C9060-509 Exam Dumps

Correct Answer: A

Explanation: After you define a storage pool, you can change the collocation setting by

updating the storage pool. The change in collocation for the pool does not affect files that are already stored in the pool.

Note:

*

When collocation is disabled, the server attempts to use all available space on each volume before selecting a new volume.

*

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. You can set collocation for each sequential access storage pool when you define or update the pool.

By using collocation, you can reduce 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.
