   Which of the following is a typical unrealistic expectation about MBT?

   • AMBT can help reduce the effort of manually writing test cases by generating them from a model.
   • BMBT requires training and skills in modeling to be used effectively.
   • CMBT requires a model of the system under test to generate test cases.
   • DMBT will automatically generate a complete and correct test suite from a poorly defined model.

   An organization assigns a junior tester with no modeling experience to create the MBT models for a critical banking application. The tester produces models that are incomplete and contain logical errors. The generated tests are unreliable and miss major defects. What is the most important action the organization should take?

   • AReplace the MBT tool with a more user-friendly one.
   • BRequire the tester to manually review all generated tests.
   • CReduce the scope of the MBT initiative to simpler applications.
   • DProvide specialized training in modeling and MBT to the tester.

   A team has a model that is technically correct but does not reflect the actual user workflows. The model was created based on outdated requirements. The generated tests pass, but they do not test the features that users actually use. What is the most likely impact of this situation?

   • AThe tests will automatically adapt to the actual user workflows.
   • BThe tests will miss critical defects in the areas that users actually use.
   • CThe tests will be more reliable because they are based on a formal model.
   • DThe tests will be more efficient because they focus on the modeled behavior.

   A development team believes that once they create a model, the MBT tool will automatically generate all possible test cases, including those for edge cases and negative testing, without any additional input. They are surprised when the generated tests miss several critical boundary conditions. What is the most important lesson from this situation?

   • AThe team should rely on manual testing for all edge cases.
   • BThe model must include explicit information about boundary conditions and negative paths.
   • CThe MBT tool should be replaced with a more advanced one.
   • DThe test oracle is responsible for finding boundary conditions.

   A team of experienced manual testers is transitioning to MBT. They are experts in test design but have no experience with formal modeling. They are given a one-day training session on the MBT tool. After a month, they have created models, but the models are of poor quality and the generated tests are not effective. What is the most likely reason for the poor results?

   • AThe testers are spending too much time on manual test design.
   • BThe testers are not using the tool's automation features correctly.
   • CThe testers lack the necessary modeling skills, which require more than a one-day training.
   • DThe MBT tool is not suitable for their application domain.
