   A test manager is deciding how much testing to perform for a legacy system that is being replaced in six months. The system is stable but has a few known critical defects that are not fixed due to cost. The replacement project has a tight deadline. What is the most cost-effective testing approach for the legacy system?

   • APerform full regression testing to ensure no new defects are introduced.
   • BInvest in fixing the known critical defects before testing.
   • CStop testing altogether and rely on user feedback.
   • DPerform minimal testing, focusing only on the most critical business functions.

   A test manager is deciding how much testing to perform for a new feature that is critical for an upcoming product launch. The feature has a high risk of defects, but the launch date is fixed and cannot be delayed. What is the most appropriate approach to balance testing cost and benefit?

   • APerform exhaustive testing to ensure the feature is defect-free before launch.
   • BSkip testing and rely on post-launch monitoring.
   • CDelay the launch to allow more testing time.
   • DPerform risk-based testing, focusing on the most critical and high-risk aspects of the feature, and accept some residual risk.
