質問 # 37
When scheduling performance testing, which of the following approaches would be most advisable? [1]
- A. Requiring all performance tests to pass before starting functional testing
- B. Deferring the start of performance testing until all functional defects have been resolved
- C. Starting the performance testing during unit and integration testing
- D. Leveraging end users to do unit-level performance testing and automated tools for system-level performance testing
正解：C
解説：
Performance testing is the process of determining the speed, responsiveness, and stability of a system under a given workload1. Performance testing should be started as early aspossible in the software development lifecycle, preferably during unit and integration testing, to identify and resolve performance issues before they become costly or risky2. Starting performance testing early can also help to validate the performance requirements, design, and architecture of the system, as well as to optimize the performance testing strategy and scope3. Therefore, option A is the correct answer. Option B is incorrect because deferring the start of performance testing until all functional defects have been resolved can delay the detection and resolution of performance issues, increase the cost and effort of performance testing, and reduce the confidence and quality of the system4. Option C is incorrect because leveraging end users to do unit-level performance testing and automated tools for system-level performance testing can introduce inconsistency, bias, and inefficiency in the performance testing process, as well as compromise the reliability and validity of the performance test results. Option D is incorrect because requiring all performance tests to pass before starting functional testing can create unrealistic or unnecessary expectations, as well as hinder the progress and feedback of the functional testing activities.

質問 # 40
You are reviewing the project's traceability matrix after the first cycle of testing. You have discovered that new requirements have been introduced and others have changed.
What should you do? [2]
- A. Ask for more time and budget for testing.
- B. Re-assess the test coverage.
- C. Update the "lessons learned" document to avoid future issues similar to this.
- D. Assign the new requirements to a maintenance release, update the test documentation for the changed requirements.
正解：B
解説：
The best action that you should take in this situation is to re-assess the test coverage. This is because the traceability matrix is a document that shows the relationship between the requirements and the test cases, and it can be used to measure the test coverage, which is the degree to which the requirements are tested. If new requirements have been introduced and others have changed, the test coverage may be affected, and some test cases may become obsolete or incomplete. Therefore, you should re-assess the test coverage and update the test cases accordingly, to ensure that the testing is consistent with the current requirements and the test objectives.

質問 # 42
Consider the following scenario:
Your customer is closely involved in the development project. Requirements are communicated verbally and rarely written down. An iterative development model is being followed and time boxing is used to stay on schedule.
Which of the following statements is true? [3]
- A. Your developers are using a waterfall methodology.
- B. Testing will start when all coding is completed.
- C. A requirements traceability matrix will be created at the start of each iteration.
- D. There is a risk that the system architecture may have to be changed during the development process.
正解：D
解説：
In an iterative development model with close customer involvement and verbal communication of requirements, there is an inherent risk of changes in the system architecture. This is due to the evolving understanding of requirements and the potential for new requirements to emerge as the project progresses.
References:The ISTQB Advanced Level Test Manager syllabus emphasizes the importance of managing risks in iterative development models1. It suggests that test managers should be prepared for changes, including possible alterations to the system architecture, as part of the risk management process23. This approach ensures that the testing strategy remains flexible and responsive to changes throughout the development lifecycle.

質問 # 49
Which classification information would be most useful to capture for newly identified defects? [2]
- A. The number of test steps in the test script that found the defect
- B. The name of the configuration manager who built the system
- C. The priority that the business assigned to the project that the defect was found in
- D. The system build that the defect was found in
正解：D
解説：
Capturing the system build information for newly identified defects is crucial as it helps in tracking the defect back to a specific state of the software. This information is essential for developers to understand the context of the defect and for testers to manage regression testing effectively. It allows for precise identification of when the defect was introduced, aiding in quicker resolution and ensuring that similar issues can be prevented in future builds.

* Defect classification and prioritisation: ISTQB offers a standardised defect classification scheme The most useful classification information to capture for newly identified defects is the system build that the defect was found in. This is because the system build is the version of the software that is compiled, integrated, and tested together. By capturing the system build for each defect, the test team can track and manage the defects more effectively, and identify the root causes and impacts of the defects. The system build can also help to reproduce and verify the defects, and to measure the quality and progress of the software development.

質問 # 50
Which of the following metrics would be most beneficial to collect to determine the effectiveness of a review process? [2]
- A. The elapsed time between each module's review and its corresponding deployment into production
- B. The development language used to create each module that was reviewed
- C. The business criticality of each module that was reviewed
- D. The number of defects found in production for each module that was reviewed
正解：D
解説：
The effectiveness of a review process can be measured by how well it detects and removes defects from the work products being reviewed1. One of the metrics that can indicate the defect detection capability of a review process is the number of defects found in production for each module that was reviewed2. This metric can show how many defects escaped the review process and were not detected until the software was deployed. A lower number of defects found in production means a higher review effectiveness. Therefore, option A is the correct answer. Option B is incorrect because the development language used to create each module that was reviewed is not relevant to the review process effectiveness. Option C is incorrect because the elapsed time between each module's review and its corresponding deployment into production is not a measure of defect detection or removal, but rather a measure of development speed or efficiency. Option D is incorrect because the business criticality of each module that was reviewed is not a measure of defect detection or removal, but rather a measure of risk or priority.
