A configuration management tool is a tool that allows users to manage and control the versions and changes of software artifacts, such as code, documents, test cases, etc. A configuration management tool can help prevent the loss of Sam’s updates by:

• Providing a centralized repository where Sam can store and retrieve his test cases and other artifacts
• Keeping track of the history and status of each artifact and allowing Sam to compare and revert to previous versions if needed
• Supporting collaboration and communication among team members by allowing them to share and access the latest versions of the artifacts

The other tools mentioned in the question are not relevant for this scenario because they do not provide the same functionality or benefits as a configuration management tool. For example:

• A. Incident management tool: This tool type allows users to record, track, manage, and report the defects found during testing. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• C. Test execution tool: This tool type allows users to execute test cases automatically or semi-automatically and compare the actual results with the expected results. It does not help with managing or controlling the versions or changes of test cases or other artifacts.
• D. Backup tool: This tool type allows users to create copies of data or files and store them in a different location or device for recovery purposes. It does not help with managing or controlling the versions or changes of test cases or other artifacts.

You can find more information about configuration management tools in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 6, Section 6.4.

Risk-based testing is an approach to testing that prioritizes and focuses on testing activities based on the level of risk associated with each feature or function of the system under test. Risk-based testing aims to optimize the use of time, resources, and techniques for testing by identifying and addressing the most critical and likely sources of failure or harm in the system under test. Some examples of typical risk-based testing activities are:

• Brainstorming sessions are held with a wide variety of stakeholders to identify possible failures in the system: This activity is part of the risk identification process, which involves gathering information and opinions from different perspectives and sources to discover potential risks in the system under test.
• Tests are prioritized to ensure that those associated with critical parts of the system are executed earlier: This activity is part of the risk analysis and evaluation process, which involves assessing the probability and impact of each risk and ranking them according to their severity and importance.
• The focus of testing is shifted to an area in the system where tests find more defects than expected: This activity is part of the risk mitigation and monitoring process, which involves taking actions to reduce or eliminate the risks and tracking their status and progress.

The evaluation of a risk-management tool to decide which tool to use for future projects is not an example of a typical risk-based testing activity because it is not directly related to testing the system under test based on its risks. Rather, it is an example of a tool selection or evaluation activity, which involves comparing and choosing a tool that can support or enhance the testing process based on criteria such as functionality, usability, reliability, compatibility, cost, etc. You can find more information about risk-based testing in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], Chapter 3, Section 3.4.

The effective ways to improve the communication and relationship between testers and others are A. a and b. Communicating factual information in a constructive way and trying to understand how the other person feels and why they react the way they do are both important skills for testers to have. Testers often have to report defects and problems that may not be well received by developers or users. Therefore, testers should communicate in a clear, objective, and respectful manner, avoiding personal attacks or blame. Testers should also empathize with the other person’s perspective and emotions, and try to resolve any conflicts or misunderstandings in a positive way. A detailed explanation of communication skills for testers can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 107-108.

The test organization that has the highest level of independence is C. Independent test specialists for specific test types, such as usability, performance or certification test specialists. Test independence refers to the degree of separation between the tester and the developer or user of the system or component under test. Test independence can help to reduce bias and increase objectivity in testing. Independent test specialists are testers who have specialized skills and knowledge in specific test types or domains and who are not involved in the development or use of the system or component under test. Independent test specialists can provide more reliable and accurate results than testers who are part of the development team or user community. A detailed explanation of test independence can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 9-10.

The question asks which of the test cases will ensure that the statement ‘Print ‘Hold’’ is exercised. The statement ‘Print ‘Hold’’ is executed when X > Y and Z < Y. Therefore, to exercise this statement, we need to choose a test case that satisfies these conditions. Among the options given in this question, only C satisfies these conditions. X = 42 > Y =43 and Z =42 < Y =43. Therefore, C is the correct answer.

Independent testing is important because C. Independent testers can verify assumptions made during specification and implementation of the system. Independent testing refers to testing performed by testers who are not involved in the development or use of the system or component under test. Independent testers can provide an unbiased and objective view of the quality of the system or component under test. Independent testers can also verify assumptions made by developers or users during specification and implementation of the system or component under test. Assumptions are statements that are believed to be true without proof or verification. Assumptions can lead to errors or defects if they are incorrect or inconsistent with reality. Independent testers can help to identify and validate assumptions by using different sources of information, such as requirements, specifications, standards, regulations, etc., and by applying different testing techniques, such as black-box techniques, white-box techniques, etc. A detailed explanation of independent testing can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 9-10.

Testing is the process of evaluating a software product by learning about it through exploration and experimentation, which includes running tests, observing outcomes, making inferences, and creating and refining test ideas. Testing has many objectives, such as finding defects, providing information, improving quality, reducing risks, etc. One of the objectives of testing is preventing defects, which means avoiding or minimizing the occurrence of defects in the software product by applying good practices and techniques throughout the software development life cycle. Preventing defects can help to save time, cost, and effort in testing and development, and improve customer satisfaction and confidence. A detailed explanation of testing objectives can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 7-8.
