ISTQB Test Manager TM12 Questions & Answers

• Question 11:

  Assume you are the Test Manager in charge of independent testing for avionics applications.

  You are in charge of testing for a project to implement three different CSCI (Computer Software Configuration Item):

  a BOOT-X CSCI that must be certified at level B of the DO-178B standard a DIAG-X CSCI that must be certified at level C of the DO-178B standard a DRIV-X CSCI that must be certified at level A of the DO-178B standard

  These are three different software modules written in C language to run on a specific hardware platform.

  You have been asked to select a single code coverage tool to perform the mandatory code coverage measurements, in order to meet the structural coverage criteria prescribed by the DO-178B standard. This tool must be qualified as a verification tool under DO-178B.

  Since there are significant budget constraints to purchase this tool, you are evaluating an open-source tool that is able to provide different types of code coverage. This tool meets perfectly your technical needs in terms of the programming language and the specific hardware platform (it supports also the specific C-compiler).

  The source code of the tool is available.

  Your team could easily customize the tool to meet the project needs. This tool is not qualified as a verification tool under the DO-178B.

  Which of the following are the three main concerns related to that open-source tool selection? (Choose three.)

  A. Does the tool support all the types of code coverage required from the three levels A, B, C of the DO178B standard?

  B. Does the tool have a good general usability?

  C. What are the costs to qualify the tool as a verification tool under the DO-178B?

  D. Is the installation procedure of the tool easy?

  E. Does the tool require a system with more than 4GB of RAM memory?

  F. Is the licensing scheme of the tool compatible with the confidentiality needs of the avionics company?

  Correct Answer: ACF

• Question 12:

  Which of the following statements about the STEP test process improvement model is true?

  A. In the STEP model, tests validate the requirements and use cases when they are developed.

  B. The STEP model stresses defect detection and demonstration of capability, whereas the defect prevention is a secondary potential goal of testing.

  C. The STEP model assures that the system requirements specification and the test design specification processes don't overlap.

  D. In the STEP model, testware design occurs after coding.

  Correct Answer: A

• Question 13:

  In your organization the following tools of the same vendor are currently in use: a requirements management tool, a test management tool and a bug tracking tool.

  You are the Test Manager.

  You are currently evaluating a test automation tool of the same vendor (to complete the vendor's tool suite) against an interesting open-source test automation tool under the GNU GPL (General Public License).

  There are no initial costs associated to that open-source tool.

  Which of the following statements associated to the selection of the open-source tool is correct in this scenario?

  A. The open-source tool can be modified but only if the community of developers of that tool gives you the formal permission to modify it.

  B. There are no initial costs for the open-source tool but you should carefully consider the costs associated to the integration with the existing tools and also evaluate the recurring costs.

  C. There are no initial costs for the open-source tool because open-source tools are usually low-quality, while vendor tools have always a better quality than the corresponding open-source tools.

  D. The open-source tool can be modified but it can't be distributed further in any way.

  Correct Answer: B

• Question 14:

  Which of the following statements about the TMMi test process improvement model is true?

  A. In TMMi all the process areas at lower levels must be 75% complete by achieving specific and generic goals in order to claim the higher level.

  B. TMMi provides an approach for test process improvement such as the IDEAL (Initiating, Diagnosing, Establishing, Acting and Learning) model.

  C. TMMi has a staged architecture for process improvement with seven maturity levels.

  D. At TMMi level 1 testing is chaotic without a defined process, and it is often seen as the same as debugging.

  Correct Answer: D

• Question 15:

  Which of the following information would you expect to be the most useful to perform a defect clustering analysis?

  A. The trend in the lag time from defect reporting to resolution

  B. The defect component information

  C. The lifecycle phase in which the defect has been introduced

  D. The defect removal efficiency information

  Correct Answer: B

• Question 16:

  Consider the following statements describing the importance of improving the test process:

  I. Test process improvement is important because being focused only on the test process it can provide recommendations to improve the test process itself, but it can't indicate or suggest improvement to areas of the development process.

  II. Test process improvement is important because it is much more effective than software process improvement to improve the quality of a software system.

  III. Test process improvement is important because several process improvement models (STEP, TPI Next, TMMi) have been developed over the years.

  IV. Test process improvement is important because every organization, regardless of the context, should always achieve the maximum level of maturity of testing described in the test improvement models such as TMMi.

  Which of the following answers is correct?

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

  B. I, II, III and IV are false.

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

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

  Correct Answer: B

• Question 17:

  During the system testing phase, a tester from your test team observes a failure in the system under test and he/she decides to create an incident report. The incident report is currently in a "new" state, indicating it needs to be investigated.

  Which THREE of the following information items can't yet be present in the incident report? (Choose three.)

  A. The type of defect that caused the failure

  B. The actual and the expected result highlighting the failure

  C. The lifecycle phase in which the defect has been introduced

  D. What really caused the failure (actual cause)

  E. Steps to reproduce the failure, including screenshots, database dumps and logs where applicable

  Correct Answer: ACD

• Question 18:

  Consider a defect report and assume that a part of its lifecycle includes the following states:

  New: Is the initial state Working: Means that the developers are addressing the defect in order to produce a fix for the defect Clarification: Means that the developers need more information from the tester to address the defect and produce a fix for the defect and the tester is working to provide this information to the developers Verification: Means that a fix for the defect has been produced and the tester is running the adequate tests to verify whether the fix solves the defect Closed: is the final state

  Which of the following answers represents an invalid sequence of states that can't lead the bug report to the “Closed” state?

  A. New, Working, Verification, Working, Clarification, Working, Verification, Closed

  B. New, Working, Clarification, Working, Verification, Closed

  C. New, Working, Verification, Working, Clarification, Working, Closed

  D. New, Working, Verification, Closed

  Correct Answer: C

• Question 19:

  During the follow-up phase the following conditions are checked:

  X1. The code has been completely reviewed.

  X2. All the identified defects have been correctly fixed and the modified code has been compiled

  successfully and run through all the static analyzers used by the project without warnings and errors.

  X3. The modified code is available under the configuration management system with a new version

  number for the specified CI.

  If these conditions are fulfilled then the review process terminates.

  Which of the following characteristics of a formal review is missing in this description?

  A. Defined entry and exit criteria

  B. Checklists to be used by the reviewers

  C. Deliverables such as reports, evaluation sheets or other review summary sheets

  D. Metrics for reporting on the review effectiveness, efficiency, and progress

  Correct Answer: D

• Question 20:

  Assume you are working on a defect management process to be used by a software organization to track the current status of the defects reports for several projects.

  When a defect is found for investigation a defect report is created in "Opened" state that is the unique initial state. The defect report status has also a unique finale state that is the "Closed" state.

  The following state transition diagram describes the states of this defect management process:

  

  where only the initial ("Opened") and final ("Closed") states are indicated while the remaining states (V, W, X, Y, Z) have yet to be named.

  Which of the following assignments would you expect to best complete the defect management process?

  A. V = Rejected, W = Corrected, X = Validated, Y = Re-Opened, Z = Assigned

  B. V = Assigned, W = Validated, X = Corrected, Y = Re-Opened, Z = Rejected

  C. V = Assigned, W = Corrected, X = Validated, Y = Re-Opened, Z = Rejected

  D. V =Corrected, W = Assigned, X = Validated, Y = Corrected, Z = Rejected

  Correct Answer: C
