IBM Information Management DB2 10.5 pureScale Technical Mastery Test v3 Sample Questions:
1. What is the purpose of the Self Tuning Memory Manager (STMM) in DB2?
A) This feature detects memory expansion in the database and delivers a warning to the DBA to let them know when the database is nearing a threshold memory allocation limit.
B) This feature reduces the task of configuring your DB2 server by continuously updating memory configuration parameters, resizing buffer pools, and dynamically determining the total amount of memory to be used by the database.
C) The purpose of this feature is for the system to deliver to you a report of database tuning recommendations so that you can update the configuration parameters by hand.
D) STMM allows DBAs to inspect the current memory allocation by buffer pools.
2. Which one of the following options is INCORRECT about DB2 pureScale?
A) DB2 10 pureScale is able to leverage DB2's Workload Manager.
B) DB2 10 pureScale introduced support for range-partitioned tables. Attach/detach operations are limited to the first and last partitions only.
C) DB2 10 pureScale introduced support for partitioned indexes and partition reorgs.
D) DB2 10 pureScale introduced support for split mirror technology as a backup method.
3. Which one of the following options is NOT a new feature introduced in DB2 10?
A) INGEST utility
B) Table Partitioning
C) Multi-Temperature Data Management
D) Temporal Tables
4. Consider the scenario that a technical expert accidentally trips over the power cord of a DB2 pureScale cluster node, bringing the node offline. Assume the cluster contains a SECONDARY cluster caching facility and other DB2 members. What will be the outcome of this situation if the node was hosting both the PRIMARY cluster caching facility and a DB2 member?
A) DB2 pureScale cannot host both the cluster caching facility and a member on a single host.
B) The secondary cluster caching facility will become the primary. All client transactions sent to be processed by the offline server will be re-routed to the remaining members within the cluster.
C) The cluster will put all transactions on hold until the server is back online.
D) The secondary cluster caching facility will be in SYNC state. All client connections will be terminated and will need to re-issued by the client.
5. In a DB2 pureScale environment, which of the following statements is NOT a characteristic of the cluster caching facility?
A) This component is used to balance the workload through a global workload resource pool.
B) This component provides a global buffer pool.
C) This component is used to coordinate locking through a global lock manager to prevent conflicting access to the same table data by different members.
D) This component is used to keep page caching consistent across all members through a shared group buffer pool.
