II) Exhaustive testing should be executed for code intended to be reused.
III) Testing may guarantee that a program is correct.
IV) Testing cannot guarantee that a program is correct.
V) Defects cluster together in certain areas of the product.

• A.I, Ill
• B.II, Iv
• C.I, IV, V
• D.I, V

Which of the following statements is true?
Select exactly one option (1 out of 4)!

• A.Defects in the program code may be caused by environmental conditions.
• B.Any deviation of the actual from the expected result represents an error.
• C.Errors are the inevitable result of software failure.
• D.Defects in the program code may result in failures in the program during execution.

Which of the following BEST defines risk level?

• A.Risk level is determined by the likelihood of an event happening and the impact or harm from that event
• B.Risk level is determined by calculating the absolute value of the sum of all potential issues that may occur on the project
• C.Risk level is calculated by dividing the sum of all known risks by the sum of all unknown risks
• D.Risk level is calculated by adding the probabilities of all planned risks to a project

A virtual service emulating a real third-party service and the automated test scripts (aimed at testing the system under test) that interact with that service, are test work products that are typically created during:

• A.Test monitoring and control
• B.Test analysis
• C.Test design
• D.Test implementation

Which of the following statements about white-box test techniques is true?

• A.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
• B.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
• C.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
• D.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
