Question 16

You are the Test Manager on a new project. The schedule is aggressive and will require the team to work at peak efficiency. The requirements are not well defined yet, but it is clear that the project will be using new technologies. To help the developers meet the development schedule, an offshore group will be added to the development team.
At this time there is not enough budget to add more testing resources. The project stakeholders are very concerned about the quality of delivered product and will be watching the project closely, particularly during the testing cycles. The exit criteria from the system test level require no open high priority/severity defects, 100% pass rate for all test cases covering risks that are classified as
"high" or "very high", 90% pass rate for all "medium" risks and 50% pass rate for all "low" and "very low" risks.
Given this information, which lifecycle model should you recommend?[3]

A.Spiral

B.Iterative/incremental

C.V-model

D.Waterfall

Correct Answer: B

An iterative/incremental lifecycle model is a type of software development lifecycle that divides the project into smaller iterations or increments, each delivering a part of the functionality and undergoing its own planning, analysis, design, implementation, and testing phases1. This model is suitable for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it allows for early feedback, risk reduction, parallel development, frequent delivery, and continuous improvement2. Therefore, option B is the correct answer. Option A is incorrect because a spiral model is a type of iterative/incremental model that adds risk analysis and prototyping activities to each iteration3. While this model can also handle unclear requirements, new technologies, and high quality expectations, it may not be the best choice for projects that have aggressive schedules and distributed teams, as it requires more time and communication for risk assessment and prototyping4. Option C is incorrect because a V-model is a type of sequential model that maps each development phase to a corresponding testing phase in a V-shaped diagram5. This model is suitable for projects that have clear and stable requirements, well-known technologies, co-located teams, and moderate quality expectations, as it allows for early verification, traceability, and defect prevention. However, this model may not be the best choice for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it does not allow for early feedback, risk reduction, parallel development, frequent delivery, and continuous improvement. Option D is incorrect because a waterfall model is a type of sequential model that follows a linear sequence of phases from requirements to deployment. This model is suitable for projects that have simple and fixed requirements, well-known technologies, co-located teams, and low quality expectations, as it allows for easy planning, management, and documentation. However, this model may not be the best choice for projects that have aggressive schedules, unclear requirements, new technologies, distributed teams, and high quality expectations, as it does not allow for early feedback, risk reduction, parallel development, frequent delivery, and continuous improvement.

Question 17

You have directed one of your testers to construct a "smoke test" to execute against new builds prior to starting formal testing. This is an example of which software development lifecycle activity?
[1]

A.Change and configuration management

B.Project management

C.Technical support

D.Software development and maintenance

Question 18

Which statement about defect management in hybrid software development is TRUE?

A.When multiple teams are working to different development models, fixes should be aligned to a separate plan that reflects the characteristics of their development model

B.When multiple teams are working in different development models, they will need to use different defect management tools

C.Defect management meetings should be held more often by teams working in Agile ways than those working in sequential ways

D.Defect management meetings should be held more often by teams working in sequential ways than those working in Agile ways

Question 19

In general, why is it NOT a good idea to estimate the testing effort based only on a percentage of development effort? Identify THREE valid reasons. 1 credit

A.The quality of the development estimate may be poor.

B.In general bottom-up estimation is always better than top-down estimation.

C.The percentage based technique only applies to the V life cycle model.

D.Using the same percentage every time does not address the level of risk of the application to be tested.

E.The maturity of the organization, e.g. the quality of the test basis, quality of development testing, configuration management, availability of test tools, also influence the effort needed for testing.

F.It builds on large set of historical data

G.The result is almost always a too low estimate for the required test effort

Question 20

You have recently implemented a new defect management process which now includes a defect triage committee whose job is to review all new defects. The process is shown in the following diagram:

b. The total number of defects rejected as not a problem following investigation by the product author c. The number of defects returned to the defect author, expressed as a percentage of all defects raised d. The total number of defects that failed re-test more than once e. The total number of defects closed by the defect triage committee SELECT ONE OPTION

A.c and d.

B.a and e.

C.a and b.

D.b and d.
