4. A number of critical bugs are fixed in software. All the bugs are in one module, related to reports. The test manager decides to do regression testing only on the reports module.
a. The test manager should do only automated regression testing.
b. The test manager is justified in her decision because no bug has been fixed in other modules
c. The test manager should only do confirmation testing. There is no need to do regression testing
d. Regression testing should be done on other modules as well because fixing one module may affect other modules
5. Which of the following is correct about static analysis tools?
a. Static analysis tools are used only by developers

b. They are used by developers only
c. They require compilation of code
d. They are useful only for regulated industries
9. Acme Inc. decides to use functional test execution automation tool for testing GUI of their product. The GUI is expected to change frequently. Acme Inc. has put some of the manual testers through a 3-day training program on how to use the tool. Which of the following is likely to be true?
a. Automation is likely to fail because of frequent changes and lack of experience
b. Automation is likely to fail because of GUI automation is not the right way to automate
c. Automation is likely to succeed because automation is very useful for frequent changes
d. Automation is likely to succeed because the team has been trained on tool.
10. In the foundation level syllabus you will find the main basic principles of testing. Which of the following sentences describes one of these basic principles?
a. Complete testing of software is attainable if you have enough resources and test tools
b. With automated testing, you can make statements with more confidence about the quality of a product than with manual testing
c. For a software system, it is not possible, under normal conditions, to test all input and output combinations.

b. A goal is to find as many failures as possible so that the cause of the failures can be identified and fixed
c. A goal is to eliminate as much as possible the causes of defects
d. A goal is to fulfill all requirements for testing that are defined in the project plan.
12. In system testing...
a. .. Both functional and non-functional requirements are to be tested
b. ... Only functional requirements are tested; non-functional requirements are validated in a review
c. ... Only non-functional requirements are tested; functional requirements are validated in a review

13. Which of the following activities differentiate a walkthrough from a formal review?
a. A walkthrough does not follow a defined process
b. For a walkthrough individual preparation by the reviewers is optional
c. A walkthrough requires meeting
d. A walkthrough finds the causes of failures, while formal review finds the failures
14. Why does the boundary value analysis provide good test cases?
a. Because it is an industry standard
b. Because errors are frequently made during programming of the different cases near the ‘edges’ of the range of values
c. Because only equivalence classes that are equal from a functional point of view are considered in the test cases
d. Because the test object is tested under maximal load up to its performance limits
