• Preparing every tested change for a deployable release

• Automatic deployment to production without manual intervention

• Merging long-lived branches before any testing happens

According to DORA metrics shown, which benefit is associated with CI/CD adoption?

• Deployments become two hundred eight times slower

• Unplanned work increases by thirty percent

• Recovery from failures slows down by six times

• Fewer service failures by a factor of about sixty

Which SDLC phase typically includes unit, integration, and security tests in an automated CI/CD workflow?

• Code phase with code reviews

• Release phase with approvals

In a CI pipeline, which action most commonly triggers the pipeline to start?

• Nightly cron job scheduler

• Dependabot opening an issue

• Manual button click by QA

• git push or git commit

Which statement best distinguishes continuous delivery from continuous deployment in CI/CD pipelines?

• Deployment is typical in regulated banking sectors

• Deployment keeps human oversight before release
