KCNA Kubernetes Fundamentals Practice Question
A user wants to run a one-time batch job that runs to completion. Which Kubernetes resource should they use?
⚠ Common exam trap
A common pitfall is assuming that a Deployment can handle batch jobs because it manages Pods, but Deployments enforce a desired replica count and restart policies that keep Pods running indefinitely, making them unsuitable for tasks that must terminate successfully after completing their work.

Correct answer & explanation
✓
Job
A Kubernetes Job is the correct resource for a one-time batch job that runs to completion. Unlike controllers designed for long-running processes, a Job creates one or more Pods and ensures they successfully terminate, making it ideal for finite tasks like data processing or backups.
