Prepare for the AZ-400 exam (Microsoft Certified: DevOps Engineer Expert). In this lesson: blue-green, canary, and ring-based deployments, feature flags and A/B testing, minimizing downtime with rolling updates and App Service slot swaps, a hotfix path, ordered dependencies, and resiliency. Includes three original practice questions.

- An App Service web app must be updated without downtime, with a fast way back if the new version misbehaves. What fits?
- A new version of an application needs a database column that does not exist yet. How should the pipeline order the work?
