   A team is modeling a distributed system where multiple users can access shared resources concurrently. The model must generate tests that detect race conditions. The team is considering using a simple state machine without explicit concurrency constructs. What is the best course of action?

   • AUse the simple state machine and add comments to indicate concurrency.
   • BModel each user separately and combine them manually during test generation.
   • CAvoid modeling concurrency and focus on functional behavior only.
   • DUse a modeling language that supports concurrency, such as a state machine with parallel regions or a Petri net.

   Which benefit is directly achieved by following modeling guidelines in an MBT project?

   • AThe model size is always minimized to the smallest possible number of elements.
   • BModels become easier to review and maintain because they follow a common style and structure.
   • CThe model automatically becomes free of all defects and ambiguities.
   • DThe MBT tool can generate test cases without any configuration.

   A team has developed an MBT model for a system with high complexity. They are about to generate tests, but they are concerned about the model's correctness. They have limited time for review. What is the most effective review strategy?

   • AConduct a full formal review with all stakeholders, checking every element against requirements.
   • BSkip the review and generate tests, then fix issues found during execution.
   • CAsk one expert to review the model independently.
   • DUse a checklist-based review focusing on common error patterns and critical requirements.

   What is the primary purpose of establishing modeling guidelines for MBT models?

   • ATo guarantee that the generated test cases are always executable without any manual intervention.
   • BTo ensure that all models are created with a consistent structure and quality, which supports maintainability and reduces misunderstandings among stakeholders.
   • CTo enforce a single universal modeling notation that all MBT tools must support.
   • DTo replace the need for test design documentation by embedding all test details directly into the model.

   A team is creating an MBT model for a login system. They want to generate tests that cover different password policies (e.g., minimum length, special characters). What should they include in the model?

   • AModel only the login process without specific test data, as test data can be added later.
   • BInclude test data for various password values and define coverage criteria for the policy rules.
   • CCreate a separate test data model and do not link it to the main model.
   • DUse a single test case that covers all password policies to keep the model simple.
