What is the primary purpose of establishing traceability links between requirements and MBT model elements?

To automatically generate all test cases without human review

To ensure coverage and enable impact analysis

To replace the need for test execution

To store the model in a version control system

A business process document states: 'If the order total exceeds $1000, apply a 10% discount; otherwise, no discount.' The MBT model has a state 'OrderProcessing' and a transition 'ApplyDiscount'. How should this process information be mapped?

Add a guard condition 'orderTotal > 1000' to the 'ApplyDiscount' transition.

Document the rule in the model's annotations but do not change the transitions.

Create a new state 'DiscountApplied' and a separate state 'NoDiscount'.

Remove the 'ApplyDiscount' transition because the discount is conditional.

A requirements change is approved: the login process must now lock the account after three failed attempts instead of five. The MBT model has a state 'FailedAttempts' with a transition to 'Locked'. What is the minimum action required to keep the model consistent with the requirements?

Update the guard condition on the transition to 'Locked' from 'failedAttempts == 5' to 'failedAttempts == 3'.

Update the requirements document to match the model's current five-attempt rule.

Delete the 'Locked' state and all related transitions.

Add a new state 'LockedAfterThree' and keep the old 'Locked' state.

Which technique is commonly used to identify gaps in requirements when linking them to an MBT model?

Running performance tests on the model

Reviewing the test execution logs

Comparing the model elements to the requirements list

A modeler links requirement REQ-88 to two different model elements because the requirement covers both a normal path and an error path. A reviewer asks why the requirement is not linked to a single element. What is the best way to address this?

Add a comment in the traceability matrix explaining that REQ-88 has two distinct behaviors that are modeled separately.

Remove the link to the error path element because the normal path is the primary behavior.

Tell the reviewer that the mapping is correct and no documentation is needed.

Change the model to combine both behaviors into a single element.

Linking Requirements and Process Related Information to the MBT Model CT-MBT Practice Questions (Page 1)

Part of the MBT Modeling domain, which makes up ~27% of our current practice bank. ISTQB does not publish an official question count, but from its 60-minute exam (~25–40 total, ~7–11 in this domain), expect 1–1 from this objective — we provide 27 practice questions to prepare you well beyond it.
