   A test engineer is reviewing a requirement for an adaptive cruise control system: 'The system shall maintain a safe following distance.' The engineer needs to assess testability. What is the best feedback to provide?

   • ASuggest that the requirement be tested using a subjective assessment by a test driver.
   • BRecommend that the requirement be split into multiple requirements for each driving scenario.
   • CAdvise that the requirement is testable as is, since 'safe' is a common term.
   • DRequest that 'safe following distance' be defined with a specific metric, such as time gap or distance in meters.

   A test manager is reviewing the traceability matrix for a braking system. She notices that requirement REQ-101 is linked to three test cases, while REQ-102 has no linked test cases. What does this indicate?

   • AREQ-101 is over-tested, and some test cases should be removed.
   • BREQ-102 is not covered by any test case, and coverage is incomplete.
   • CThe traceability matrix is complete because REQ-101 has multiple tests.
   • DREQ-102 is implicitly covered by the test cases for REQ-101.
