   In a sequential SDLC, how are models typically used across phases?

   • AModels are created early and remain largely unchanged
   • BModels are discarded after requirements
   • CModels are only used in the testing phase
   • DModels are updated in every phase

   In a sequential SDLC, how are MBT activities typically performed?

   • AAs a single, upfront effort completed before coding begins
   • BOnly during the testing phase, with no earlier model creation
   • CAd hoc, without a defined sequence
   • DIn repeated cycles with continuous model updates

   An agile team is using MBT and has a model that is updated each sprint. They want to ensure that the tests generated from the model are relevant to the current sprint's changes. What is the best way to achieve this?

   • AGenerate tests manually for the changed areas and use automated tests for the rest.
   • BGenerate tests only at the end of the project to save time.
   • CGenerate tests only from the parts of the model that were updated in the current sprint.
   • DGenerate tests from the entire model every sprint to ensure full coverage.

   In a sequential SDLC, where do MBT activities (model creation, test generation, execution) typically fit?

   • AModel creation in design, test generation in implementation, execution in maintenance
   • BMBT activities are performed only after deployment
   • CAll MBT activities are performed only in the testing phase
   • DModel creation in requirements, test generation in design, execution in testing

   A company developing a safety-critical embedded system uses a sequential SDLC. Requirements are frozen, and the design is complete. The test team is about to begin system testing. They have just created a model of the system's expected behavior from the approved requirements. What is the most appropriate next step in applying MBT?

   • AUse the model to generate test cases, but delay execution until the next phase to avoid interfering with development.
   • BWait until coding is complete and then create the model from the code to ensure accuracy.
   • CGenerate test cases from the model and execute them against the system, then update the model only if defects are found.
   • DContinuously refine the model based on feedback from each test execution cycle, even if requirements have not changed.
