   What is the purpose of early test design as a preventive testing practice?

   • ATo reduce the number of testers needed during execution
   • BTo identify ambiguities and missing requirements before they become defects
   • CTo ensure that all test cases are automated before development starts

   A test analyst is working with a development team that frequently writes code without considering error handling for network timeouts. The analyst has seen this pattern cause many defects in the past. What is the most effective way for the test analyst to collaborate with the developers to prevent this defect pattern?

   • ACreate a checklist for testers to use when testing network-related features.
   • BOrganize a knowledge-sharing session where the analyst presents common error-handling defect patterns and works with developers to define coding standards for network calls.
   • CAdd more test cases that simulate network timeouts to the test suite for every new feature.
   • DReport every network timeout defect as a high-severity issue to management to pressure the developers.

   A test analyst is investigating a high rate of defects in a data migration project. The defects are all 'data mismatch' errors, but they occur in different fields and at different stages of the migration. The analyst has limited time for the investigation. Which approach would be most effective for identifying the root cause and informing a prevention strategy?

   • AConduct a full brainstorming session with the entire project team to discuss all possible causes of data mismatch.
   • BReview the code of the migration tool line by line to find the logic errors.
   • CCreate a fishbone diagram with categories like 'people', 'process', and 'technology' and fill it with all possible causes.
   • DUse a Pareto analysis on the defect data to identify the most frequently affected data fields, then trace those specific fields back through the migration mapping documents.

   How can a test analyst share knowledge with developers to support defect prevention?

   • ABy keeping test results confidential to avoid conflict
   • BBy reporting defects only at the end of the project
   • CBy focusing solely on test execution and not on analysis
   • DBy providing feedback on common defect patterns and their likely causes
