Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
podman rm stopped
Why it's wrong here
stopped is not a valid target keyword for podman rm.
- ✓
podman container prune
Why this is correct
podman container prune deletes all stopped containers after prompting for confirmation (or use -f to skip prompt).
- ✗
podman system clean
Why it's wrong here
podman system clean is not the correct command; podman system prune exists, but container prune is more specific.
- ✗
podman rm --all
Why it's wrong here
podman rm does not take an --all flag without specifying IDs or filters; podman container prune is designed for this.
