What is a key consideration when creating a data model for defect detection?

Focusing on the user interface layout of data entry forms

Including only the data fields that are currently used by the system

Representing the data relationships and constraints accurately

Documenting the physical storage location of the data

A test analyst is proposing the use of model-based defect detection to a project manager. The project manager is concerned about the time and effort required to create models. The analyst wants to address this concern. Which response is the most appropriate?

Promise that the modeling effort will be minimal and will not affect the project schedule.

Explain that the initial modeling effort is an investment that can pay off by finding defects earlier and reducing rework.

Argue that model-based testing is the only way to ensure quality.

Suggest that the team can skip modeling and use the tool's default models.

What is the purpose of analyzing a state model to identify unreachable states?

To identify states that cannot be reached from the initial state, which may indicate missing transitions or logic errors

To verify that the model matches the user interface design

To ensure that all states are accessible to the user

To reduce the number of test cases needed

What is the primary purpose of using models in model-based defect detection?

To systematically derive test cases and expected results that can reveal defects

To document the final software architecture for maintenance purposes

To automatically fix defects in the software under test

To replace the need for any manual testing activities

Part of the Software Defect Prevention domain, which makes up ~29% of our current practice bank. ISTQB does not publish an official question count, but from its 120-minute exam (~50–80 total, ~15–23 in this domain), expect 3–5 from this objective — we provide 26 practice questions to prepare you well beyond it.
