a) A product for release being developed under extreme time pressure by a team of 2.

b) Complex testing software that will be used by several teams within the company to conduct formal testing.

c) Simple utility used by only a few members of the same team and is not released outside of the team or to the customer.

d) It is never appropriate to use this method.

5. You are in the process of developing requirements for a medical device. The device is typically purchased on the order of physicians but is actually used by the nursing staff in the hospital. Which statement is true:

a) The requirements of the nursing staff should take precedence as an error using the device could have significant consequences for the patient.

b) The requirements of the physician should take precedence as they are the ones who will actually buy the product.

c) The development team should implement both sets of requirements with equal priority, consulting with both groups if any requirements conflict.

d) The development team should use both requirements as guidelines and develop their own set of requirements that the team feels is best.

6. Product risk is:

a) Any event that can occur that will negatively impact the cost of the project.

b) Any event that can occur that will negatively impact the quality of the final product.

c) All of these are correct.

d) Any event that can occur that will negatively impact the delivery date of the product.

7. Product Verification is:

a) The process of formal testing of the product against the requirements to determine if the system was constructed properly.

b) The process of formal testing of the product against the intended use to determine if the product meets the needs of the customer.

c) The process of formal testing of the product manufacturing process to determine if the manufactured product meets the specified requirements.

d) The complete suite of formal testing including a., b., and c.

8. Your Q/A Testing team has found a defect in the product. Your design/implementation team has isolated the defect to a single module and has fixed it. You have neither the time nor the resources to completely re-test the system but you want a high level of confidence that the change is correct with no other bugs introduced. What testing will you do:

a) Fully test the module that was changed.

b) Fully test the module + Fully test all of the modules that directly interface with the modified module.

c) Fully test the module + all of the modules that interface with it + random testing elsewhere in the system.

d) Fully test the module, all interfacing modules, all critical requirements, and random testing in every other module.

9. Is this requirement Testable? "The response time to user input while the system is fully loaded should be fast enough"

a) No: "fast enough" is not specific enough.

b) No: "response time" is too vague

c) Yes: "fast enough" is an easy value to determine and, therefore, is sufficiently accurate.

d) No: both a and b

10 Which is not a primary function of a change control board (CCB)?

a) Prioritize proposed changes against other changes to assign change requests to a given release.

b) Perform detailed analysis of a change request to determine impact of the change to the system.

c) Authorize change requests to be implemented for the current release.

d) Review proposed changes to determine appropriateness and ease of implementation.

11. Which of the following is NOT a reason why an independent reviewer is important in a design review?

a) Being the most senior developer in the company, they are best positioned to find errors in the implementation and suggest solutions.

b) Since they do not work on the project, they are not driven by the same schedule commitments or reporting structure as the project team. This allows them to more freely identify problems or make suggestions that may negatively impact the project's schedule.

c) They provide insight into the system without pre-existing biases resulting from the current design.

d) Design decisions made earlier will often be revisited and challenged by the independent reviewer who has not had the benefit of previous discussions and may have a different set of

12. What sort of items can be placed under the control of configuration management software?

a) Product Source Code

b) Requirements documents

c) Test cases and results.

d) Design descriptions.

e) All of these can be placed under configuration control.

13. In the context of configuration management, a "Branch" is created when:

a) A second development path is created based upon a snapshot of the main development path for a given product.

b) A release is made and the configuration management database is labeled.

c) The term "Branch" is not commonly used in configuration management.

d) A new, independent, development path is created based upon a snapshot of the main development path for use in a completely new product.

14. Which of the following are required for a properly written test case:

a) Approval by appropriate team members PRIOR to the execution of the test case.

b) Expected results for each test case step that requires evaluation of results

c) Links (ID numbers, etc...) back to the requirement(s) that drive this test case.

d) All of these are required.

b) Outsourcing a technological challenging component to an expert using a contract that rewards speed and low cost while penalizing late and expensive results.

c) Selecting a less technically challenging component.

d) Forging ahead with the development realizing that there may be challenges and agreeing to handle the consequences if they occur.
