   A team uses an MBT tool that generates low-level test cases from a model. After a model change, the tool regenerates the test cases, but the team notices that some previously passing test cases are no longer generated. What is the most likely cause?

   • AThe tool has a bug that randomly drops test cases
   • BThe high-level test cases were deleted by the team
   • CThe model change altered the paths or conditions that those test cases covered
   • DThe test environment was reconfigured and is no longer compatible

   A team maintains a large MBT suite for a product with frequent requirement changes. They currently store only low-level test cases with hard-coded values. Each requirement change forces them to update many test cases manually. What change would most effectively reduce maintenance effort?

   • AIntroduce high-level test cases and regenerate low-level cases from the model after each change
   • BIncrease the number of low-level test cases to cover all possible changes
   • CKeep the low-level test cases but add more comments to explain each value
   • DStop using the model and write all test cases manually from requirements

   An MBT model contains a high-level test case 'Verify user can transfer funds between accounts'. The team needs to execute this on both a web application and a mobile application. How should the team proceed in the MBT process?

   • ADelete the high-level test case and write two independent test cases from scratch
   • BCreate a single low-level test case that works for both platforms by using generic selectors
   • CExecute the high-level test case directly on both platforms without modification
   • DRefine the high-level test case into two low-level test cases, one for each platform, with platform-specific details

   A test lead needs to produce a report showing that every low-level test case can be traced back to a specific requirement. What must be in place to create this report?

   • AA detailed test execution log for every test case
   • BA list of all defects found during testing
   • CA copy of the requirements document stored with the test cases
   • DTraceability links from low-level test cases to high-level test cases and model elements that reference requirements
