   A test engineer is reviewing a requirement for a head-up display: 'The display shall show the vehicle speed clearly.' The engineer needs to provide feedback to improve testability. Which feedback is most effective?

   • AAdvise that the requirement is testable as is, since 'clearly' is understood.
   • BSpecify the minimum font size and contrast ratio for the speed display.
   • CRecommend that the requirement be tested only during daylight conditions.
   • DSuggest that the display be tested by a panel of users for clarity.

   A test engineer is reviewing a requirement for an electric vehicle charging system: 'The system shall charge the battery quickly.' The engineer needs to provide feedback to make the requirement testable. Which feedback is most appropriate?

   • ADefine 'quickly' with a specific charging time or rate, such as 'from 20% to 80% in under 30 minutes'.
   • BSuggest that 'quickly' be tested by comparing with a competitor's charging time.
   • CRecommend that the requirement be tested only in ideal temperature conditions.
   • DAdvise that the requirement is testable as is, since 'quickly' is a common term.

   A test team is designing tests for a power window system. Two requirements conflict: Requirement A says 'The window shall close automatically when the ignition is turned off.' Requirement B says 'The window shall remain in its current position when the ignition is turned off.' How should the test team handle this conflict?

   • APrioritize Requirement A because it involves safety.
   • BEscalate the conflict to the requirements owner or product manager to resolve before test design.
   • CCombine the requirements into a single test case that verifies both behaviors.
   • DDesign test cases for both behaviors and note that one will fail.

   A test engineer is updating the traceability matrix for a software update to an existing infotainment system. The update adds a new requirement REQ-301 and modifies REQ-302. The engineer notices that the existing test case TC-200 is linked to REQ-302, but the modification changes the expected behavior. What is the best action?

   • AKeep TC-200 unchanged and create a new test case for REQ-301 only.
   • BUpdate TC-200 to reflect the modified behavior of REQ-302, and create a new test case for REQ-301.
   • CAsk the requirements owner to revert the modification to REQ-302.
   • DRemove the link between TC-200 and REQ-302 and create a new test case for REQ-302.
