CompTIA Linux+ XK0-006 (V8) Practice Question

A Linux administrator is trying to recover several gigabytes of disk space on a Docker host. She needs a single interactive command that will remove all stopped containers, any user-defined networks not attached to a container, dangling images, and build cache while retaining every named volume and any image that still has at least one tag-even if that image is not currently used by a container. Which Docker CLI command meets these requirements?

  • docker image prune -a

  • docker system prune -a

  • docker system prune

  • docker system prune --volumes
