XK0-006 Practice Question: A system administrator wants to deploy a…
A system administrator wants to deploy a containerized application on a Linux server with minimal overhead and without a daemon. Which container runtime should be used?
⚠ Common exam trap
The trap here is that candidates often associate 'container runtime' with Docker or containerd, but the question specifically tests the distinction between daemon-based and daemonless architectures, where Podman's fork-exec model is the key differentiator.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Podman
Podman is the correct choice because it is a daemonless container engine that runs containers directly under the user's process space, using a fork-exec model rather than a background daemon. This aligns with the requirement for minimal overhead and no daemon, as Podman does not require a persistent service to manage containers.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
containerd
Why it's wrong here
containerd runs as a persistent daemon managing containers, so it fails the no-daemon requirement. It is tempting because containerd is a lightweight, widely used runtime that suits minimal-overhead container hosting, and would be correct where a daemon-based runtime with Kubernetes CRI support is acceptable.
- ✗
LXC
Why it's wrong here
LXC creates system containers through liblxc and typically depends on the LXD daemon for management, so it fails the no-daemon requirement. It is tempting because LXC provides lightweight OS-level isolation with low overhead, and would be correct when running full system containers rather than single application containers.
- ✗
Docker
Why it's wrong here
Docker relies on the dockerd daemon to manage containers, directly violating the no-daemon requirement. It is tempting because Docker is the most familiar container runtime and offers minimal overhead relative to full virtualisation, and would be correct where a daemon-based toolchain and image build workflow are wanted.
- ✓
Podman
Why this is correct
Podman runs containers rootless and daemonless, launching each container directly as a child process rather than through a persistent background service. This satisfies the stem's explicit no-daemon constraint while keeping overhead minimal, unlike Docker's dockerd. Its OCI-compatible tooling also mirrors familiar Docker commands, easing deployment.
