The correct answer is A, as it states that the Wideband Delphi estimation technique is an example of the expert-based approach. The Wideband Delphi estimation technique is a method of estimating testing effort or duration by using a structured group process that involves multiple experts2. The experts provide their estimates independently and anonymously, then compare and discuss them until they reach a consensus2. This technique is an example of the expert-based approach, which is an approach that relies on the knowledge and experience of experts to estimate testing activities2. Option B is incorrect, as it states that the Wideband Delphi estimation technique is an example of the metrics-based approach. The metrics-based approach is an approach that uses historical data and mathematical formulas to estimate testing activities2. This approach does not involve experts or group processes. Option C is incorrect, as it states that burndown charts used in Agile development is an example of the expert-based approach. Burndown charts are graphical tools that show the amount of work remaining versus time in an Agile project2. They are used to monitor and control testing progress and quality. They are not examples of the expert-based approach, as they do not rely on experts’ opinions or estimates. Option D is incorrect, as it states that burndown charts used in Agile development is an example of the risk-based approach. The risk-based approach is an approach that uses risk analysis to prioritize and estimate testing activities2. This approach involves identifying and assessing risks based on their likelihood and impact. It does not involve burndown charts or Agile development. References: 2, Section 2.6

A correct reason to apply test automation is when there are a lot of repetitive testing tasks, as test automation can reduce the effort and time required to execute them, and improve the consistency and accuracy of the results. The other options are not valid reasons to apply test automation, as they do not consider the benefits and risks of test automation, the suitability of the test object for automation, or the availability of resources and skills for automation.

 According to the syllabus, dynamic analysis tools are tools that perform testing or analysis by executing the software or a part of it. Dynamic analysis tools can help detect defects or problems that only appear during runtime, such as memory leaks, performance issues, concurrency errors, etc. The answer A is correct because it suggests using a dynamic analysis tool for detecting a memory leak during performance testing. A memory leak is a situation where a code component fails to release memory after it has finished using it, causing memory exhaustion and degradation of performance. A dynamic analysis tool can monitor the memory usage of the code component and identify any memory leaks. The other answers are incorrect because they suggest using tools that are not suitable for detecting memory leaks during performance testing. A test execution tool is a tool that executes test cases automatically or semi-automatically. A configuration management tool is a tool that controls and tracks changes to the software components and documentation. A coverage measurement tool is a tool that measures how much of the code or functionality has been exercised by a test suite.
