質問 5：
A test manager decided to skip static testing since he believes bugs can be found easily by doing dynamic testing. Was this decision right or wrong?
A. The decision was wrong. Static testing can find defects early in the development process, reducing the overall cost of testing and development
B. The decision was wrong. Ensuring quality mandates that static testing is performed after performing the dynamic testing.
C. The decision was right. Most of the bugs are easier to identify during the dynamic testing.
D. The decision was right. Static testing is usually redundant if a product is planned to go through a full- cycle of dynamic testing.

質問 6：
Which of the following statements about white-box test techniques is true?
A. Branch coverage is the most thorough code-related white-box test technique, and therefore applicable standards prescribe achieving full branch coverage at the highest safety levels for safety-critical systems
B. Achieving full statement coverage and full branch coverage for a software product means that such software product has been fully tested and there are no remaining bugs within the code
C. Code-related white-box test techniques are not required to measure the actual code coverage achieved by black-box testing, as code coverage can be measured using the coverage criteria associated with black-box test techniques
D. Code-related white-box test techniques provide an objective measure of coverage and can be used to complement black-box test techniques to increase confidence in the code
