質問 # 47
Which of the following principles should be followed when introducing a test tool into an organization?
(i) Assessing organizational maturity to establish whether a tool will provide expected benefits.
(ii) Requiring a quick payback on the initial investment.
(iii) Including a requirement for the tool to be easy to use without having to train unskilled testers.
(iv) Identifying and agreeing requirements before evaluating test tools.
- A. (ii) and (iii)
- B. (i) and (ii)
- C. (iii) and (iv)
- D. (i) and (iv)
正解：D
解説：
Assessing organizational maturity (i) is very important when deciding whether to introduce a test tool, as implementing a tool in an immature test organization with poor processes is unlikely to produce any benefits.
A quick return on the initial investment (ii) in a test tool is rare.
Having a requirement that a tool should be easy to use for untrained and unskilled testers (iii) is generally a false hope. This is comparable with expecting someone who has never driven a car to be able to drive safely and effectively.
Agreeing requirements before evaluating tools (iv) is essential. Not to do so would be comparable with building and testing a system without requirements.
In conclusion, (i) and (iv) are good principles to follow when introducing a tool and (ii) and (iii) are not.

質問 # 53
Which of the following describes structure-based (white-box) test case design techniques?
- A. Test cases are derived systematically from models of the system.
- B. Test cases are derived from the developers' experience.
- C. Test cases are derived systematically from the delivered code.
- D. Test cases are derived systematically from the tester's experience.
正解：C
解説：
Answer (A) relates to specification-based testing, answer (B) relates to experience-based testing and answer (D) could relate either to debugging or to experience-based techniques.
質問 # 54

Which of the following Test Cases based on the decision table are Valid?
Test Case 1:
An employee who is not a car or motorcycle driver attempts to claim fuel expenses. Expected result:
Expense claim not allowed.
Test Case 2:
An employee who drives a 1700cc diesel car attempts to claim fuel expenses. Expected result: Expense claim accepted at band C.
Test Case 3:
An employee who rides a motorcycle attempts to claim fuel expenses. Expected result: Expense claim accepted at band A.
- A. Test Case 2 is Valid. Test Cases 1 and 3 are Invalid.
- B. Test Cases 1, 2 and 3 are all Valid.
- C. Test Cases 1 and 3 are Valid. Test Case 2 is Invalid.
- D. Test Cases 2 and 3 are Valid. Test Case 1 is Invalid.
正解：C
質問 # 55
Which of the following statements correctly describes traceability?
- A. The degree to which a requirement is stated in terms that permit establishment of test design.
- B. An approach to integration testing where the component at the top of the component hierarchy is tested first.
- C. The capability of the software product to enable modified software to be tested.
- D. The ability to identify related items in documentation, such as requirements vs. software design

質問 # 56
Tools like change Man, Clear case are used as..?
- A. performance testing tools
- B. none of the above
- C. functional automation tools
- D. configuration management tools
正解：D
質問 # 57
Component testing may include:
- A. The use of stubs and drivers.
- B. User acceptance testing.
- C. Sociability testing.
- D. Beta testing.
正解：B
解説：
Component testing, also known as unit testing, involves testing individual components of the software separately. This type of testing focuses on the functionality of a specific section of the code. To facilitate this process, stubs and drivers are often used. Stubs are dummy modules that simulate the behavior of lower-level modules that are not yet integrated. Drivers are used to simulate higher-level modules that control the component being tested.
Reference: ISTQB CTFL Syllabus, version 4.0, mentions the use of stubs and drivers in the context of component testing.
質問 # 58
Which of the following are valid test objectives?
(i)Finding defects.
(ii)Gaining confidence about the level of quality and providing information.
(iii)Preventing defects.
(iv)Debugging the code.
- A. ii and iii
- B. i, ii and iii
- C. i, ii and iv
- D. i and iv
正解：B
解説：
Valid test objectives include finding defects (i), gaining confidence about the level of quality and providing information (ii), and preventing defects (iii). Debugging the code (iv) is not a valid test objective as it is a part of the development process rather than the testing process.
Reference: ISTQB CTFL Syllabus, version 4.0, lists the valid objectives of testing, which include finding defects, gaining confidence, and preventing defects.
質問 # 59
A live defect has been found where a code component fails to release memory after it has finished using it.
Which of the following tools would have been the MOST effective at detecting this defect prior to live implementation?
- A. Configuration management tool
- B. Dynamic analysis tool
- C. Coverage measurement tool
- D. Monitoring tool
正解：B
解説：
A dynamic analysis tool would have been the most effective at detecting a defect where a code component fails to release memory after use. These tools analyze the behavior of the software while it is running, allowing them to identify issues like memory leaks, which occur when memory is not properly freed. Dynamic analysis tools can monitor the allocation and deallocation of memory in real-time, helping to pinpoint the exact location and cause of the memory leak before the software is deployed .
質問 # 60
Evaluate the status of the project against the defined exit criteria. Which of the following options shows the correct status? 2 credits
- A. Criteria A = OK, criteria B = NOT OK, criteria C = NOT OK
- B. Criteria A = NOT OK, criteria B = NOT OK, criteria C = OK
- C. Criteria A = NOT OK, criteria B = NOT OK, criteria C = NOT OK
- D. Criteria A = OK, criteria B = OK, criteria C = OK
正解：B
質問 # 61
Which pair of definitions is correct?
- A. Regression testing involves running all tests that have been run before; retesting runs new tests.
- B. Regression testing is checking there are no additional problems in previously tested software; retesting enables developers to isolate the problem.
- C. Regression testing is checking that there are no additional problems in previously tested software, retesting is demonstrating that the reported defect has been fixed.
- D. Regression testing is checking that the reported defect has been fixed; retesting is testing that there are no additional problems in previously tested software.
正解：C
解説：
Regression testing is testing that nothing has regressed. Retesting (or confirmation testing) confirms the fix is correct by running the same test after the fix has been made. No other option has both of these as true.
