   A test manager is deciding how much regression testing to perform for a web application that is updated frequently. The application has a large user base, and defects in production have high impact. Which approach best applies cost-benefit analysis to determine the appropriate level of regression testing?

   • APerform risk-based regression testing, focusing on areas with high impact and frequent changes.
   • BSkip regression testing and rely on production monitoring to detect issues.
   • CPerform full regression testing for every release to ensure no defects reach production.
   • DPerform the same regression testing as the previous release, regardless of changes.

   A product owner wants to reduce the testing budget for a low-risk internal tool by skipping regression testing for the next release. The test manager must decide whether to accept this. Which action best aligns with a cost-benefit analysis of this decision?

   • AReject the reduction because regression testing is mandatory for all releases regardless of risk.
   • BPropose to replace regression testing with a full retest of all functionality to ensure quality without extra cost.
   • CAccept the reduction because the tool is internal and the risk is low, saving costs immediately.
   • DAnalyze the potential impact and likelihood of defects in the new release, then compare the cost of regression testing with the expected cost of defects if skipped.

   A test manager is deciding how much testing to perform for a system that has a low probability of failure but a very high impact if it fails (e.g., a medical device). The cost of testing is high due to regulatory requirements. What is the most appropriate approach to balance testing cost and benefit?

   • APerform extensive testing to reduce the risk of failure, despite the high cost.
   • BPerform minimal testing because the probability of failure is low.
   • CSkip testing and rely on post-market surveillance.
   • DPerform the same level of testing as for a low-risk system.
