   A team is using MBT to test a customer relationship management (CRM) system. The test objective is to verify that the system correctly handles customer data updates, including creating, modifying, and deleting customer records. Which modeling technique is most appropriate?

   • AA use case diagram listing the actors and use cases for customer management
   • BA sequence diagram showing the interaction between the customer and database objects
   • CA state machine that models the lifecycle of a customer record (e.g., new, active, inactive, deleted)
   • DA class diagram showing the attributes of the customer class

   A team is using MBT to generate tests for a system with multiple test objectives: (1) verify that all states are reachable, (2) verify that all transitions are executed, and (3) verify that specific critical paths are covered. The team has limited test execution time. What is the best way to guide test generation?

   • AGenerate tests randomly and hope they cover the objectives
   • BPrioritize test generation based on the objectives: first cover critical paths, then cover as many states and transitions as possible within the time limit
   • CGenerate tests that cover all states and transitions, and then add tests for critical paths
   • DGenerate tests that only cover the critical paths, as they are the most important

   A test objective focuses only on the login functionality of a system. What is the appropriate level of detail for the MBT model?

   • AModel the login behavior only after all other features are modeled
   • BModel the login behavior at a very high level without any details
   • CModel only the login behavior with sufficient detail to generate tests for login scenarios
   • DModel all system features in full detail to avoid missing anything

   Which factor most directly influences the choice of modeling technique (e.g., state machine vs. decision table) in MBT?

   • AThe operating system on which the tests will run
   • BThe programming language used to implement the system under test
   • CThe number of testers available on the team
   • DThe test objectives, because different objectives require different modeling notations and levels of abstraction

   A team is starting MBT for a banking application. Their primary test objective is to verify that the login module handles all combinations of valid, invalid, and expired credentials correctly. Which modeling approach best aligns with this objective?

   • AA detailed decision table for the login module, focusing on input combinations and expected outcomes
   • BA use case diagram listing all actors and their interactions with the system
   • CA sequence diagram showing the interaction between the login module and the database
   • DA high-level state machine covering the entire application flow, including account management and transactions
