   A test team has classified defects from the last three releases using a standard scheme. The data shows that 'configuration' defects have increased from 10% to 35% of all defects. The team wants to recommend a process improvement. Which action is most directly supported by this trend?

   • AFocus all testing effort on functional requirements and ignore configuration scenarios.
   • BReview the configuration management process to identify why configuration-related defects are increasing.
   • CIncrease the number of testers to reduce the overall defect count.
   • DReplace the defect classification scheme with a simpler one to reduce classification effort.

   A test team is using a fishbone diagram to analyze why a new feature fails only in the production environment, not in test. The diagram includes categories for Environment, Data, Process, and People. The team has identified 'production database has different data' as a potential cause. The test manager wants to ensure the analysis is thorough. What should the team do next?

   • AInvestigate the specific differences in production data that could trigger the failure, such as data volume, null values, or special characters.
   • BRemove the 'production database has different data' branch because it is an environmental issue, not a defect.
   • CStop the analysis and ask the operations team to fix the production database.
   • DConclude that the production environment is different and recommend testing only in production.

   A test team is selecting a defect classification scheme to support root cause analysis. They need a scheme that can be applied consistently by testers with minimal training and that provides enough detail to distinguish between coding errors, design flaws, and requirement gaps. Which characteristic should the team prioritize when evaluating schemes?

   • AA well-defined taxonomy with clear definitions and examples for each category.
   • BA scheme with only two categories to keep it simple.
   • CA scheme that automatically classifies defects based on code changes.
   • DA scheme that focuses only on severity and priority.
