   What is the main goal of pairwise testing?

   • ATo test parameters in pairs of two at a time
   • BTo test only the most important parameter values
   • CTo reduce the number of test cases while ensuring all pairs of parameter values are covered
   • DTo test all possible combinations of parameter values

   A test analyst is designing tests for a complex eligibility system for a government benefit program. The system has multiple input conditions: income level (low, medium, high), family size (1, 2, 3+), and disability status (yes, no). The output is the benefit amount (full, partial, none). The analyst has created a cause-effect graph to visualize the relationships. However, the graph is complex, and the analyst is struggling to convert it into a comprehensive set of test cases. The analyst wants to ensure that all combinations of conditions are covered. What is the most appropriate next step?

   • AUse use case testing to derive test scenarios from user interactions with the eligibility system.
   • BUse state transition testing to model the eligibility states and transitions.
   • CUse pairwise testing to reduce the number of test cases while covering all pairs of conditions.
   • DConvert the cause-effect graph into a decision table to systematically derive test cases for all combinations of conditions.

   What is the purpose of the classification tree method?

   • ATo systematically partition input domains and generate test cases
   • BTo trace system failures back to root causes
   • CTo model system states and transitions
   • DTo identify potential failure modes and their effects
