IBM P2090-054 Exam Syllabus Topics:

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

1. Which one of the following options is CORRECT?

A) In both DB2 pureScale and HADR environments data is available all the time.
B) In a pureScale environment, the data is available all the time, while in a HADR environment the data is available most of the time.
C) DB2 pureScale transfers log files from a primary database to a standby database.
D) HADR persists data in the cluster caching facilities (CFs).

2. Consider the scenario where a client application is connected to DB2 pureScale "member 1". The DB2 pureScale environment has three DB2 pureScale members. In a situation where "member 1" fails, the client is still able to execute operations against the DB2 pureScale cluster with minimal interference. Which of the following technologies allow the client to continue performing operations?

A) Redundant cluster caching facility.
B) Automatic Client Reroute.
C) Geographically Dispersed pureScale Cluster (GDPC).
D) Decentralized log files for member recovery.

3. Which of the following options is correct about possible configurations for DB2 pureScale's network topology?

A) DB2 pureScale supports multiple cluster interconnect adapter ports for the cluster members which increases the bandwidth to process more transactions, thus improving performance. It also supports multiple switches, which greatly improves network resiliency.
B) DB2 pureScale supports multiple cluster interconnect adapter ports for the cluster caching facilities which increases the bandwidth to handle more requests, thus improving performance. It also supports multiple switches, which greatly improves network resiliency.
C) DB2 pureScale does not support multiple cluster interconnect adapter ports, but It supports multiple switches, which greatly improves network resiliency.
D) DB2 pureScale supports multiple cluster interconnect adapter ports for both cluster caching facilities and members. It does not support multiple switches.

4. The DB2 Storage Optimization feature allows you to save storage by compressing your database data. Which one of the following types of compression is new in DB2 10?

A) Classic Row Compression
B) Adaptive Compression
C) Declared Global Temporary Tables Compression
D) Temporary Tables Compression

5. Which of the following options justifies why you should be actively monitoring buffer pool hit ratios on your DB2 pureScale environment?

A) Attaining high local buffer pool (LBP) and global buffer pool (GBP) hit ratios are in general an indication of overall good performance as more pages are found in memory than having to fetch from I/O.
B) Low local buffer pool (LBP) hit ratios are the only important metric that must be monitored since it indicates that there are a higher number pages fetched directly from physical storage than from the local buffer pool.
C) High local buffer pool (LBP) hit ratios are the only important metric that must be monitored since it indicates that there are a higher number of pages fetched from physical storage than from the local buffer pool.
D) Attaining low local buffer pool (LBP) and global buffer pool (GBP) hit ratios are in general an indication of overall good performance as more pages are found in memory than having to fetch from I/O.
