Why are containers meant to be immutable?

To allow SSH access into the machine.

To avoid the need for automated testing.

To rebuild and redeploy the whole image instead of patching live containers. (correct)

To enable patching live containers easily.

What is the advantage of patching images in the container registry instead of patching live containers?

Achieving content addressability.

Directly scanning production clusters for vulnerabilities.

Avoiding the need for canarying.

Rolling out fully patched container images as one unit. (correct)

How does using containers help in avoiding downtime while patching newly discovered vulnerabilities?

By manually patching each instance in a task.

By achieving content addressability.

By rolling out patched images with blue/green deployments. (correct)

By frequently scanning production clusters.
