   A development team uses a CI/CD pipeline that automatically deploys to production on every push to the main branch. After a security incident, they want to add a security review step without slowing down the pipeline too much. What is the best approach?

   • ARun the security scan only on release branches, not on every push.
   • BDeploy to production first and run the security scan after.
   • CAdd an automated security scan that runs in parallel with the build and tests, and require it to pass before deployment.
   • DAdd a manual security review step that requires a security engineer to approve every deployment.

   A small team is setting up a CI/CD pipeline for a Python application. They want to use a tool that is easy to configure, runs on their own infrastructure, and supports building, testing, and deploying. They have no existing automation infrastructure. Which tool should they choose?

   • AGitHub Actions, but only if they migrate their code to GitHub.
   • BA cloud-based CI/CD service that requires no infrastructure management.
   • CA custom shell script that runs build, test, and deploy commands manually.
   • DJenkins, running on a dedicated server, with a pipeline defined in a Jenkinsfile.

   A company runs a web application in production. They want to deploy a new version with zero downtime and be able to roll back quickly if the new version has issues. They have enough infrastructure to run two full production environments. Which deployment strategy best meets these requirements?

   • ARecreate deployment, where the old version is stopped before the new version is started.
   • BCanary deployment, where the new version is released to a small subset of users before full rollout.
   • CRolling deployment, where the new version is gradually deployed across the existing instances.
   • DBlue-green deployment, where the new version is deployed to an idle environment and traffic is switched over after validation.

   A team is developing a web application with a large end-to-end test suite that takes 45 minutes to run. They want to run these tests in the CI pipeline, but they also want developers to get feedback within 10 minutes of pushing code. Which approach best balances these constraints?

   • ARun the full end-to-end suite in the CI pipeline on every commit and accept the 45-minute feedback time.
   • BRun a subset of critical end-to-end tests in the CI pipeline and run the full suite in a nightly or on-demand pipeline.
   • CRun the end-to-end suite in parallel with unit tests in the CI pipeline and fail the build if any test fails.
   • DRun only unit tests in the CI pipeline and run the end-to-end suite nightly.
