• Question 22:

  You are the Test Manager of a project that adopts a V-model with four formal levels of testing: unit, integration, system and acceptance testing.

  On this project reviews have been conducted for each development phase prior to testing, which is to say that reviews of requirements, functional specification, high-level design, low-level design and code have been performed prior to testing.

  Assume that no requirements defects have been reported after the release of the product.

  Which TWO of the following metrics do you need in order to evaluate the requirements reviews in terms of phase containment effectiveness? (Choose two.)

  A. Number of defects found during the requirements review.

  B. Total number of defects attributable to requirements found during unit, integration, system and acceptance testing.

  C. Total number of defects found during functional specification review, high-level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing.

  D. Time to conduct the requirements review.

  E. Total number of defects attributable to requirements, found during functional specification review, high-level design review, low-level design review, code review, unit testing, integration testing, system testing and acceptance testing.

  Correct Answer: AE

• Question 23:

  The main objectives the senior management team wants to achieve are:

  to reduce the costs associated with dynamic testing to use reviews to ensure that the project is on course for success and following the plan to use reviews as a well-documented and effective bug-removal activity following a formal process with well-defined roles to determine the effectiveness of reviews in terms of phase containment to improve phase containment effectiveness

  Which of the following answers would you expect to describe the best way to achieve these objectives?

  A. You should plan for lightweight exit-phase reviews at the end of each development and testing phase, and plan for a process of gathering information from testing to perform an analysis aimed at identifying the larger cluster of defects.

  B. You should plan for formal exit-phase reviews at the end of each development and testing phase, and plan for a process of gathering information from testing to perform an analysis aimed at identifying the larger cluster of defects.

  C. You should plan for formal exit-phase reviews at the end of each development phase and testing phase, and plan for a process of gathering information from testing to perform an analysis of the bugs found during testing to determine the people responsible for those bugs.

  D. You should plan for formal exit-phase reviews at the end of each development and testing phase, and plan for a process of gathering information from testing to perform an analysis of the bugs found during testing to determine the phase in which they have been introduced.

  Correct Answer: D

• Question 24:

  You are a Test Manager working for a software organization where reviews have never been applied. After a meeting with your managers examining a business case for reviews, (including their costs, benefits, and potential issues), the management finally decides to adopt formal reviews for future projects.

  You have been given a budget that you have spent to provide training in the review process and to introduce the review process on a pilot project.

  On that pilot project the introduction of reviews has been very positive in terms of positive involvement from all the participants. All the reviews applied to different documents have been very effective for their purposes (especially at revealing defects).

  Which of the following answers describes an important success factor for the introduction of formal reviews which is missing in this scenario?

  A. Management support

  B. Participant support

  C. Definition and use of metrics to measure the ROI (Return On Investment)

  D. Training in the review process

  Correct Answer: C

• Question 25:

  Consider the following list of statements about audits and management reviews:

  I. Audits are usually more effective than management reviews at finding defects.

  II. Audits and management reviews have the same main goals, the only difference is related to the roles and level of formality.

  III. A typical outcome of an audit includes observations and recommendations, corrective actions and a pass/fail assessment.

  IV. An audit is not the appropriate mechanism to use at the code review in order to detect defects prior to dynamic testing.

  Which of the following statements is true?

  A. I and III are true; II and IV are false;

  B. II and III are true; I and IV are false;

  C. III and IV are true; I and II are false;

  D. I, III and IV are true; II. is false;

  Correct Answer: C

• Question 26:

  You are managing the system testing for a SOA based system. The integrated system consists of several subsystems:

  a SOA middleware a CRM (Customer Relationship Management) system a BRM (Billing and Revenue Management) system a SMS (Subscriber Management System) system

  and you performed a risk analysis based on these subsystems.

  At the end of the scheduled period for test execution you produce a first classical report based on the traditional metrics of testing. Test pass/fail status and bug status (open/resolved) That table provides you a distorted picture of the quality risk, because there is no indication of the risk level of the failed tests, the tests not run, or the open bugs. Thus, you produce the following table to solve this distortion issue: In the table above, where you have introduced the concept of risk weighting, the highest risk test or bug report has a score of 1, while the lowest risk test or bug report has a score of 0.04.

  

  Which of the following subsystems, based on the risk scores of the table, is most risky?

  A. SOA

  B. CRM

  C. BRM

  D. SMS

  Correct Answer: B

• Question 27:

  For which of the following activities would the costs be classified as a cost of detection?

  A. Writing test specifications according to the test design.

  B. Training developers to better understand the new features of the coding language they will use on the project.

  C. Re-running a test case, during the system testing phase, to verify that a fix eliminates a previously found defect.

  D. Fixing field failures.

  Correct Answer: A

• Question 28:

  Assume you have some data related to confirmation testing during system testing of a past project.

  In that project 240 bug reports have been opened once, 80 were opened twice, 10 were opened three times and no bug reports have been opened more than three times.

  You estimate that a bug report, which has failed its confirmation test, costs, on average, 3 person-hours. Which of the following statements correctly describe the value of these confirmatory testing activities based on cost of quality?

  A. 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure.

  B. 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of external failure.

  C. 340 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of internal failure.

  D. 300 person-hours have been spent on the project during the system testing phase, because of the failed confirmation tests and this cost belongs to the costs of detection.

  Correct Answer: A

• Question 29:

  Which of the following answers describes a factor that may reduce the effort spent when using distributed test teams without negatively affecting system quality?

  A. Difficulties in communication between the distributed test teams due to time zone differences.

  B. With several distributed test teams, every team assumes that some test conditions are covered by other teams but actually no one covers them.

  C. With several distributed test teams, two or more teams assume some test conditions are covered by their team and their team alone. But all of the teams actually cover them.

  D. With several distributed test teams, all of the distributed test teams use a single unified test dashboard.

  Correct Answer: D

• Question 30:

  The following chart plots the cumulative number of defects opened against the cumulative number of defects closed during system testing of a software product.

  

  Which of the following statements is true?

  A. The chart indicates that you have plenty of problems left to find.

  B. The chart can be used to reveal test progress problems.

  C. The chart seems to indicate that the defect management process is not working well.

  D. The chart seems to indicate that the defect management process is working well.

  Correct Answer: D
