C. The DB2 Design Advisor is a tool that automatically analyzes your running database and continuously makes changes to your database to give it peak performance.
D. The DB2 Design Advisor is a tool that can help you improve your database workload performance. Given a set of SQL statements in a workload, the Design Advisor can generate recommendations to improve the performance of SQL execution.
正解：D

質問 4：
Which one of the following sentences does NOT describe a benefit of Temporal Tables?
A. Temporal tables increase business insight by letting analysts understand how the business was doing in the past, what has changed in the present, what are the projections for the future.
B. Temporal tables allow better data management by letting the application control data integrity and uniqueness.
C. Temporal tables provide a quick and easy way to track and record data changes in the table.
D. Temporal tables lower costs by eliminating the complexity for businesses to develop their own temporal support infrastructure, such as additional tables, triggers, and application logic.
