KCNA Container Orchestration Practice Question
Which Kubernetes resource should be used to run a one-time task that performs a computation and then exits?
⚠ Common exam trap
Many candidates confuse a Job with a Deployment because both can run containers, but a Deployment is designed for long-running services, not for tasks that should terminate after completion.
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
✓
Job
A Kubernetes Job is designed specifically for finite, one-time tasks that run to completion and then exit. Unlike controllers that maintain a desired number of continuously running Pods, a Job creates one or more Pods and tracks their successful termination, making it the correct choice for a computation that should run once and stop.
