   A CI pipeline has grown to include many stages: lint, unit tests, integration tests, build, and deploy. The team notices that the pipeline often fails at the integration test stage due to flaky tests, and this blocks the deploy stage. The team wants to reduce the impact of flaky tests on the overall pipeline. What should they do?

   • AIncrease the timeout for the integration test stage so flaky tests have more time to pass.
   • BRemove the integration test stage from the pipeline entirely to ensure the deploy stage always runs.
   • CConfigure the pipeline to retry the integration test stage a limited number of times before marking it failed.
   • DMove the integration test stage to run after the deploy stage so it does not block deployment.

   What is the primary purpose of dependency caching in a CI pipeline?

   • ATo replace the need for a package manager
   • BTo store compiled binaries for production deployment
   • CTo speed up builds by reusing previously downloaded dependencies
   • DTo ensure dependencies are always updated to the latest version

   A Python project's CI pipeline installs dependencies using `pip install -r requirements.txt`. Recently, a transitive dependency released a new version that broke the build. The team wants to prevent this from happening again while still getting security updates for direct dependencies. What is the best approach?

   • AAdd a version range like `>=1.0,<2.0` for the direct dependency to allow pip to pick any compatible version.
   • BPin all direct and transitive dependencies to exact versions in a lock file and update it deliberately through a separate process.
   • CConfigure pip to cache all downloaded packages so the same versions are always reused.
   • DRemove the transitive dependency from requirements.txt and rely on pip to resolve a compatible version automatically.

   A CI pipeline has a long-running integration test suite that takes 45 minutes. The team wants to provide faster feedback to developers. They are considering splitting the test suite into smaller chunks that can run in parallel. What is the most important factor to consider when splitting the tests?

   • AEnsure that tests in different chunks do not have dependencies on each other or share mutable state.
   • BEnsure that the test chunks are run sequentially to avoid resource contention.
   • CEnsure that each chunk has an equal number of tests to balance the load.
   • DEnsure that the test chunks are run on the same build agent to avoid network latency.

   What is a key practice for optimizing CI pipeline flow?

   • ADisabling tests to speed up the pipeline
   • BRunning tests in parallel where possible
   • CUsing a single large build job for all tasks
   • DRunning all tests sequentially to ensure accuracy
