   A test team has 120 requirements for an electric power steering system. They have written test cases for 90 requirements. To achieve 100% requirement coverage, what must the team do?

   • AAdd more test cases to the already covered requirements.
   • BCreate test cases for the remaining 30 requirements.
   • CReport 100% coverage because 90 out of 120 is acceptable.
   • DRemove 30 requirements from the scope to match the current test cases.

   A test team is working on an autonomous emergency braking (AEB) system. They have 50 test cases, but only 30 of them are linked to specific requirements in the traceability matrix. The project manager asks for a coverage report. What is the most appropriate action to ensure accurate requirement coverage measurement?

   • ALink the remaining 20 test cases to the requirements they verify, or mark them as not requirement-based if they test other aspects.
   • BDelete the 20 unlinked test cases to ensure all test cases are traceable.
   • CReport requirement coverage as 60% (30/50) based on the currently linked test cases.
   • DAsk the requirements engineer to rewrite the requirements to match the existing test cases.

   A test manager is analyzing requirement coverage for a telematics system. There are 200 requirements. The traceability matrix shows that 150 requirements have at least one test case. However, 20 of those requirements are only linked to test cases that are marked as 'blocked' due to a missing hardware component. What is the effective requirement coverage?

   • A75%
   • B85%
   • C65%
   • DCannot be determined without knowing the number of test cases.

   What does it mean for a requirement to be 'testable'?

   • AIt has been reviewed by the test team.
   • BIt is approved by the customer.
   • CIt is written in a formal language.
   • DIt is possible to design a test case that can verify whether the requirement is met.

   A test lead is planning the test strategy for a new airbag control unit. The project has a tight deadline, and the test budget is limited. The requirements are well-defined and stable. Which approach best aligns with requirements-based testing principles while managing the constraints?

   • ADelay test design until the system is implemented to observe actual behavior.
   • BUse exploratory testing to find defects without predefined test cases.
   • CPrioritize test cases that directly verify each requirement, focusing on high-risk requirements first.
   • DCreate test cases only for the most complex requirements to save time.
