   A team is using a CI server that builds the application and runs unit tests. The build takes 20 minutes, and developers often commit multiple times per day. The team wants to reduce the feedback time. Which approach would be most effective?

   • ARun the build only on the main branch, not on feature branches.
   • BUse a build server with more powerful hardware to speed up the build.
   • CReduce the frequency of commits to once per day to give the build time to complete.
   • DSplit the build into parallel stages so that independent parts of the build and test run concurrently.

   A team is adopting continuous integration. They currently run a full regression test suite that takes 45 minutes. Developers are reluctant to commit frequently because they do not want to wait for the long build to complete before receiving feedback. Which approach best addresses this concern while preserving the benefits of continuous integration?

   • ARequire developers to run the full regression suite locally before committing to the main branch.
   • BIncrease the timeout of the CI job so that the full regression suite can complete without interruption.
   • CReduce the frequency of commits to once per day to allow the full regression suite to run overnight.
   • DRun a fast subset of tests on every commit and run the full regression suite on a nightly basis.

   A tester on an agile team notices that the CI pipeline runs a large suite of automated tests, but the team often ignores the results because they are not sure which failures are relevant to their current work. What should the tester recommend to improve the effectiveness of the CI feedback?

   • AHave the team review all test results at the end of the sprint to avoid interrupting development.
   • BDisable the CI pipeline for feature branches and only run it on the main branch.
   • CIncrease the number of tests in the CI suite to ensure all possible defects are caught.
   • DConfigure the CI tool to send notifications only for failures related to the most recent commit.

   A team is setting up a CI environment for the first time. They have a version control system, but they are unsure how to structure their build and test process. Which combination of practices best aligns with continuous integration principles?

   • AUse a separate CI server for each developer to avoid interference between builds.
   • BRun the build manually at the end of each day and report results in the daily stand-up meeting.
   • CAutomate the build and run tests on every commit to the main branch, and notify the team of failures immediately.
   • DOnly run tests on the CI server when a release candidate is created.
