A city permitting portal team still ships a fat Ubuntu VM-style image into the cluster and wonders why builds and pulls take forever. What should they do for a Kubernetes application image?
Select an answer to reveal the explanation.
Short Explanation
Think of packing for a weekend trip versus moving an entire apartment. Kubernetes wants a small suitcase with just the app runtime—not a full Ubuntu living room stuffed into every Pod. Slim bases mean faster builds, smaller pulls, and less attack surface.
Full Explanation
CKAD focuses on defining and building application container images suitable for Kubernetes, not shipping VM appliances. A minimal base (for example distroless or alpine-class images when appropriate) plus only required runtime libraries reduces layer size, pull latency, and unnecessary packages. Nested VMs and cluster-install tooling are out of scope for application image design.
