A CD pipeline deploys to a staging environment and then to production. The team wants to add a checkpoint that validates the staging deployment is ready for production promotion. They have limited time and want to balance thoroughness with speed. Which checkpoint is most appropriate?

Run a subset of critical end-to-end tests and a smoke test against the staging environment.

Run only a smoke test against the staging environment and promote immediately.

Skip testing in staging and rely on production monitoring after deployment.

Run the full regression suite against the staging environment before every production promotion.

A team's CI pipeline runs automated tests and publishes results to a dashboard. Some tests are flaky and fail intermittently, causing the pipeline to fail and block merges. What is the best practice to handle flaky tests in CI?

Configure the pipeline to automatically retry failed tests up to three times before failing.

Ignore test failures in the pipeline and rely on manual testing to catch issues.

Remove flaky tests from the suite permanently to keep the pipeline stable.

Quarantine flaky tests and investigate them separately while keeping the pipeline green for reliable tests.

A company wants to implement continuous deployment to production. They have a strong automated test suite, but they are concerned about the risk of deploying a change that passes tests but causes a production incident. Which strategy best mitigates this risk while maintaining continuous deployment?

Implement progressive delivery with canary releases, automatically rolling back if error rates exceed a threshold.

Deploy only during a weekly maintenance window to minimize the impact of incidents.

Run all tests in production after deployment and roll back if any test fails.

Require a manual approval from the QA lead before each production deployment.

A team supports release on demand for a mobile app, but the release schedule is driven by business needs and can happen at any time. The QA team wants to ensure the app is always ready to release. What is the most effective approach?

Maintain a release candidate branch that is always tested and kept ready for release.

Rely on the development team to manually verify the app before each release.

Release the latest build from the main branch without additional testing.

Run the full test suite only when a release is requested.

Which of the following is an example of a QA checkpoint in a CD pipeline?

Sending a notification to the release manager

Running automated smoke tests after deployment to a staging environment

Updating the version number in the source code

Creating a backup of the database
