An organization maintains traceability links between requirements, test models, and test cases. A requirement change is proposed that affects a specific model element. The team needs to assess the impact before approving the change. What is the most effective use of traceability links?

Ask the test team to manually review all test cases to find any that might be affected.

Review the test execution history to see which test cases have failed recently.

Identify all test cases linked to the affected model element and estimate the effort to update them.

Consult the test environment documentation to determine if any configuration changes are needed.

An organization uses MBT for a critical healthcare system. A change is made to the patient data handling process, affecting several requirements and model elements. The team must update the MBT artifacts and maintain traceability. What is the most important consideration when updating the traceability links?

Ensure that every changed requirement is linked to the corresponding updated model elements and test cases, and that obsolete links are removed.

Only update the links for the most critical requirements, as updating all links is too time-consuming.

Delete all traceability links and recreate them from scratch after the change is implemented.

Keep the original traceability links unchanged to preserve historical evidence of the old requirements.

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

Delete all traceability links and recreate them after the change is fully implemented.

Keep the original traceability links to preserve the history of the change.

Update the traceability links to reflect the new requirement, model elements, and test cases, and remove any obsolete links.

Only update the links for the changed requirement, leaving other links as they are.

A change is made to the system under test (SUT) that affects the expected behavior of a specific feature. Which MBT work product is MOST directly impacted by this change?

The test environment configuration

A software team uses MBT for a mobile app. A change is made to the login module to support biometric authentication. The team has a test model and a set of generated test cases. What is the most appropriate regression testing strategy?

Delete all test cases related to the login module and generate new ones from the updated model.

Re-run all existing test cases that cover the login module and generate new test cases for biometric authentication.

Run only the newly generated test cases for biometric authentication.

Re-run the entire test suite without any changes to the model.
