An existing CI workflow packages an application. The developer must prevent regressions and ensure the tested artifact is the one deployed. Which practices meet this goal? Select 2 answers.

1. Run relevant automated checks against representative behavior and fail the release on critical failures.
2. Ignore failed checks whenever a commit message says production ready.
3. Promote the same identified artifact through the approved environments rather than silently rebuilding untracked content.
4. Deploy a different branch than the one used to create the test artifact without recording the change.
5. Delete every older artifact before observing the new release.
