KCNA Kubernetes Fundamentals Practice Question
You want to run a batch job that processes data and then terminates. Which Kubernetes resource is best suited for this workload?
⚠ Common exam trap
CNCF often tests the distinction between controllers that maintain 'desired state' (Deployments, StatefulSets) versus controllers that manage 'completion' (Jobs), and the trap here is that candidates mistakenly choose Deployment for any workload that 'processes data' without recognizing the terminating nature of the task.

Correct answer & explanation
✓
Job
A Kubernetes Job is designed for batch processing workloads that run to completion and then terminate. Unlike controllers that maintain a desired number of running Pods (like Deployments or StatefulSets), a Job creates one or more Pods and ensures they successfully exit. Once the specified number of successful completions is reached, the Job stops, making it the ideal choice for a one-time data processing task.
