   A sequential SDLC project is in the maintenance phase. A change request is approved that modifies a small part of the system. The test team has a model that was used for the original system. What is the most appropriate MBT action?

   • AUpdate the model to reflect the change, regenerate tests for the affected area, and execute them along with regression tests.
   • BCreate a completely new model for the entire system to ensure accuracy.
   • CDo not update the model; manually test the changed area instead.
   • DUpdate the model but do not regenerate tests because the change is minor.

   How does the choice of sequential SDLC affect the benefits of adopting MBT?

   • AMBT provides maximum flexibility for changes
   • BMBT has no benefits in sequential lifecycles
   • CMBT provides early test design but changes are costly to incorporate
   • DMBT benefits are identical in all lifecycles

   A project uses a sequential SDLC. The system model was created during the design phase and used to generate tests. During system testing, a defect is found that requires a change in the system's behavior. What should be done with the model?

   • AUpdate the model but do not regenerate tests because the change is minor.
   • BDelete the model and create a new one from the updated code.
   • CUpdate the model to reflect the corrected behavior, regenerate affected tests, and re-execute them.
   • DLeave the model unchanged and document the defect as a known issue.

   In a waterfall project, the system design is complete and the test team is about to create test models. The project manager wants to ensure that the models accurately reflect the system's behavior. What is the most reliable source for creating the test model at this point?

   • AThe test plan, which outlines the testing strategy.
   • BThe detailed design document.
   • CThe approved requirements document.
   • DThe source code, which is already available.
