   A team uses a CI tool that triggers a build on every push to the repository. The build compiles the code and runs unit tests. However, the team wants to also run code quality checks and security scans. Which action would be most appropriate?

   • ARun code quality and security scans manually on a weekly basis.
   • BAdd additional stages to the CI pipeline for code quality and security scanning.
   • CUse a separate CI tool for code quality and security scans to avoid slowing down the build.
   • DReplace the unit tests with code quality and security scans to save time.

   Why is test automation important for continuous integration in agile projects?

   • ABecause it reduces the need for version control.
   • BBecause it allows tests to be run frequently and quickly, providing fast feedback to the team.
   • CBecause it guarantees that all defects are found before release.
   • DBecause it eliminates the need for testers in the project.

   A team has a CI pipeline that runs on every commit to the main branch. The build takes 15 minutes, and the team has a policy that the main branch must always be green. However, developers often have to wait for the build to finish before they can merge their changes, causing delays. The team wants to reduce the wait time without compromising the 'always green' policy. Which approach is most effective?

   • AImplement a build pipeline that runs faster tests first and provides early feedback, while still running the full suite before allowing a merge.
   • BReduce the frequency of commits to the main branch to once per day to reduce the number of builds.
   • CAllow developers to merge without waiting for the build to complete, and fix any failures later.
   • DUse a more powerful build server to reduce the build time, even if it increases cost.

   A team has a CI pipeline that runs a build and unit tests. The build is fast, but the unit tests are flaky and sometimes fail without any code changes. The team is considering removing the flaky tests from the CI pipeline to reduce noise. Which approach is most appropriate?

   • AInvestigate and fix the flaky tests so that they are reliable, then keep them in the CI pipeline.
   • BRemove the flaky tests from the CI pipeline to avoid false failures.
   • CIncrease the number of times the flaky tests are run to increase the chance of passing.
   • DMove the flaky tests to a nightly pipeline to avoid blocking the main CI feedback loop.

   How does continuous integration reduce integration risk in agile projects?

   • ABy requiring all developers to work on the same branch simultaneously.
   • BBy performing a single large integration at the end of the project.
   • CBy integrating code changes frequently, so conflicts are identified and resolved early.
   • DBy avoiding the use of version control systems.
