質問 1：
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, 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
C. 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.
D. 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.
正解：A

質問 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. Decentralized log files for member recovery.
D. Geographically Dispersed pureScale Cluster (GDPC).
正解：B

質問 3：
Which one of the following options is correct about the differences between the IMPORT and INGEST utilities?
A. The IMPORT utility is now deprecated and INGEST is the recommended alternative.
B. The IMPORT utility can import data into a database, while the INGEST can only create database objects based on a script file.
C. The INGEST is capable of transforming and streaming data from files and pipes at high speeds into DB2 tables. The IMPORT utility cannot transform the data.
D. The IMPORT utility can perform lightweight transformations on the data being processed. The INGEST utility cannot transform data.
正解：C

質問 4：
What are some of the benefits of DB2 Express?
A. DB2 Express is fastest and most powerful DB2 edition.
B. DB2 Express is designed for development and testing. It is not used as a production database.
C. DB2 Express has affordable licensing terms with all of the core features of the DB2 engine.
D. DB2 Express is a tool that allows DBAs to quickly solve complex database issues.
正解：C

質問 5：
What is the DB2 Load utility?
A. The DB2 Load utility can be used to load and create external functions in a DB2 database.
B. The DB2 Load utility is a tool that allows you to directly transfer data and objects from another database into the one you are currently working with.
C. The DB2 Load utility is a high-speed, low-level, data loading utility that loads data into a DB2 database.
D. The DB2 Load utility is a tool that stores all scripts that are required to create the database. It does not load data, but just loads the database metadata that was exported for a site backup.
正解：C

質問 6：
Which of the following statements is FALSE when monitoring the high usage of lock memory in a DB2 pureScale environment?
A. Request for locks might be denied.
B. Data concurrency issues can arise due to a high number of lock escalations.
C. Performance will not be affected due to high usage of Lock Memory.
D. Lock escalations can take place if there is insufficient memory.
正解：C

質問 7：
Which one of the following options is CORRECT?
A. HADR persists data in the cluster caching facilities (CFs).
B. In both DB2 pureScale and HADR environments data is available all the time.
C. In a pureScale environment, the data is available all the time, while in a HADR environment the data is available most of the time.
D. DB2 pureScale transfers log files from a primary database to a standby database.
正解：C
