A team uses MBT and maintains traceability links between requirements, model elements, and test cases. A requirement is added, and the team updates the model and generates new test cases. What is the most important action to maintain traceability?

Delete all existing traceability links and recreate them from scratch.

Create traceability links from the new requirement to the new model elements and test cases.

Only link the new requirement to the model, not to the test cases, to save time.

Keep the traceability links unchanged, as the new requirement does not affect existing links.

When a change is made to the test model, what is the typical next step in updating MBT artifacts?

Update the test execution results to match the new model

Regenerate the affected test cases from the updated model

Delete all test cases and start over

Manually edit all existing test scripts to match the change

When a change is made to the test model, what is the primary purpose of performing change impact analysis?

To rewrite the entire test suite to ensure consistency

To determine which test cases and execution results are affected by the change

To update the test environment to match the new model

To document the change in the final test report

A retail banking system's test model includes a state machine for transaction processing. A new regulatory requirement mandates that all transactions above $10,000 require an additional approval step. The team updates the system requirements and the test model. Which MBT work product is most directly affected by this change, and what is the primary impact?

The test environment configuration, which must be updated to simulate the new approval step.

The test execution logs, which need to be archived to preserve evidence of the old approval process.

The test model's state transitions and guard conditions, leading to changes in generated test cases and expected results.

The test data files, which need new sample transactions above $10,000 to cover the new rule.

A team uses an MBT tool that generates test scripts from a model. A change is made to the system under test that affects a specific model element. The team updates the model and regenerates the test scripts. What is the most important thing to verify after regeneration?

That the test environment is configured to run the regenerated scripts.

That the old test scripts are deleted to avoid confusion.

That the regenerated test scripts are consistent with the updated model and cover the changed behavior.

That the test data files are updated to support the new test scripts.

Part of the MBT Test Implementation and Execution domain, which makes up ~16% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~4–6 in this domain), expect 1–2 from this objective — we provide 21 practice questions to prepare you well beyond it.
