   A team has a large amount of technical debt in the form of duplicated code and complex conditionals. The team is planning a major release and wants to ensure that the code is maintainable. The product owner is concerned that refactoring will introduce regressions. What is the most effective strategy to address the debt while minimizing risk?

   • AUse static analysis to identify the debt and create a report for the product owner.
   • BPerform a large-scale refactoring in a dedicated sprint to address all the debt at once.
   • CRefactor the code incrementally, using the existing test suite and adding tests for uncovered areas before each refactoring step.
   • DDefer all refactoring until after the release to avoid any risk.

   A team is using a static analysis tool that flags a large number of potential null pointer dereferences. The developer argues that these are false positives because the code is correct. The tester wants to ensure that the tool is useful. What is the best approach?

   • AReview the flagged issues together, and if they are false positives, adjust the tool's configuration or add suppressions with justification.
   • BIgnore the static analysis results and rely on code reviews instead.
   • CDisable the null pointer checks to eliminate the noise.
   • DRequire the developer to fix all flagged issues, even if they are false positives.
