AI-200: Developing AI Cloud Solutions on Azure

Question

You manage several versions of a container image in Azure Container Registry.

The production deployment must consistently run the identical image build, even if tags change later.

You need to guarantee predictable, immutable image selection during deployment. What should you do?

Explanation

A container image manifest digest is a unique SHA-256 content identifier for that exact image build. Deploying by digest pins the deployment to that image even if a tag such as production or latest is later moved to another build.
