   A team is using MBT for a large legacy system. Stakeholders have conflicting priorities: the business wants to ensure that the most frequently used features are thoroughly tested, while the security team wants to ensure that all security-related functions are tested, even if they are rarely used. The team has limited modeling resources. What should they do?

   • AFocus only on the business needs, as they are the primary stakeholders
   • BCreate two separate models: one focused on frequently used features and one focused on security functions
   • CFocus only on security needs, as they are more critical
   • DCreate a single model that covers all features, with equal detail for all

   A team is using MBT for a web application. The test objective is to verify that the system correctly handles user sessions, including login, logout, and session timeout. However, the team also needs to test the system's performance under load. They have limited time and resources. What is the best approach?

   • ACreate a single detailed state machine that models both session behavior and performance characteristics
   • BCreate a performance model and use it for both session and performance testing
   • CCreate a state machine for session behavior and use a separate performance testing tool for load testing
   • DFocus only on session behavior and skip performance testing

   A team is using MBT to test a new e-commerce checkout process. The main test objective is to verify that the system correctly handles different payment methods (credit card, PayPal, and bank transfer) and their error paths. Which modeling technique would be most effective?

   • AA business process model (BPMN) that shows the entire order-to-delivery process
   • BA state machine that models the checkout states and transitions, including payment method selection and error handling
   • CA class diagram showing the structure of the payment classes and their relationships
   • DA use case diagram listing the actors and use cases for the checkout process

   A team is using MBT for a financial system. Stakeholders have expressed two main concerns: (1) the system must be highly reliable, and (2) the system must be delivered quickly to meet a market deadline. The team has limited modeling resources. What is the best way to derive test objectives that balance these concerns?

   • AFocus on reliability testing and accept a longer delivery time
   • BFocus on speed of delivery and reduce the scope of reliability testing
   • CPrioritize test objectives based on risk: focus on the most critical reliability aspects that can be tested within the time frame
   • DCreate a comprehensive model that covers all reliability aspects and hope to meet the deadline

   A team is using MBT to test a simple calculator app. The test objective is to verify that the basic arithmetic operations (addition, subtraction, multiplication, division) work correctly for all integer inputs. What level of model completeness is required?

   • AA model that only covers addition and subtraction, as they are the most common operations
   • BA high-level model that shows the main screens and navigation, without detailing each operation
   • CA model that covers each operation with representative input values and expected outputs
   • DA model that includes all possible integer inputs and their expected outputs for each operation
