✍️ Sample ISTQB Questions & Answers

1. In agile development, what testing activity typically occurs during a sprint review?

✓ Acceptance testing with stakeholders

Sprint reviews involve demonstrating working software to stakeholders, which often includes acceptance testing to validate delivered functionality.

2. What does 'residual risk' mean after testing is completed?

✓ The risk that remains after testing and mitigation activities have been applied

Residual risk is the level of risk that persists after all planned testing and other mitigations have been performed; it is typically accepted by stakeholders before release.

3. In control flow testing, what is a 'predicate' node?

✓ A node where the flow splits based on a condition

A predicate node is a decision point in the control flow graph where execution can follow different paths based on a Boolean condition.

4. According to ISTQB, which of the following is an example of a 'project risk' (as opposed to a product risk)?

✓ Key test personnel may leave the project mid-cycle

Project risks threaten the test project's success, such as personnel turnover, while product risks relate to the software quality.

5. In white-box testing, what does a 'du-path' represent in data flow analysis?

✓ A path from where a variable is defined to where it is used

A du-path (definition-use path) traces the execution path from where a variable is defined (assigned) to where it is subsequently used.

6. In the context of ISTQB, which factor most significantly determines whether a test tool will deliver expected benefits?

✓ The degree to which the tool is adopted and used correctly within the organization

Tool success depends primarily on organizational adoption and correct usage; even the best tool delivers no value if improperly used or ignored.
