IBM P2090-054 Exam Syllabus Topics:

IBM Information Management DB2 10.5 pureScale Technical Mastery Test v3 Sample Questions:

Question 1

Which of the following options does NOT describe a benefit of DB2's Row Compression?

A. Compression allows you to cache more data in the buffer pools using the same amount of space.
B. Compression allows you to reduce CPU workload because there is less data to process.
C. Compression allows you to store the same amount of data in less space, which can significantly save storage costs.
D. Compression allows you to retrieve the same amount of data using fewer disk operations (I/O).

Question 2

Which of the following statements describes the STMM (Self-Tuning Memory Manager) functionality in a DB2 pureScale environment?

A. When Self-Tuning Memory Manager is enabled in a DB2 pureScale environment, if the member on which the memory manager is running deactivates, the memory manager will automatically start up on another member that is currently able to run the memory manager. In order for a member to run the memory manager, the database must be active on that member and that member must have SELF_TUNING_MEM set to ON.
B. When Self-Tuning Memory Manager is enabled in a DB2 pureScale environment, the secondary cluster caching facility monitors the memory configuration and propagates any configuration changes to all members.
C. When Self-Tuning Memory Manager is enabled in a DB2 pureScale environment, if the member on which the memory manager is running deactivates, the memory manager will remain off until the member is activated. In order for a member to run the memory manager, the database must be active on that member and that member must have SELF_TUNING_MEM set to ON
D. When Self-Tuning Memory Manager is enabled in a DB2 pureScale environment, the primary cluster caching facility monitors the memory configuration and propagates any configuration changes to all members.

Question 3

How does DB2 pureScale balance the workload among its members?

A. Workload balance is handled by the Self Tuning Memory Manager (STMM) feature.
B. Workload balance must be handled by the application.
C. Workload balance cannot be handled by DB2 pureScale. It must be handled by a third-
party application.
D. Workload balance is automatically performed by DB2 pureScale by rerouting the workload to members with lighter loads.

Question 4

Consider a scenario where your DB2 pureScale cluster caching facilities are in PEER state. What would be the state of the secondary cluster caching facility upon failure of the primary cluster caching facility and a successful takeover?

A. PEER
B. PRIMARY
C. NEW_PRIMARY
D. ERROR

Question 5

Consider the scenario where a database administrator is required to restore a database backup for a DB2 pureScale environment. Which of the following statements is correct?

A. The RESTORE DATABASE command will need to be executed on the shared storage to restore the database. The metadata cannot be retrieved until the shared storage is restarted.
B. The RESTORE DATABASE command will need to be executed on each DB2 member within the cluster to restore just the database. A separate command will be required to restore the metadata for each member.
C. The RESTORE DATABASE command will need to be executed on each DB2 caching facility within the cluster to restore just the database. All node metadata is not recoverable since it is not stored within database backups.
D. The RESTORE DATABASE command will need to be executed on only one of the members within the cluster. This operation will restore both the database and metadata for all members.
