Which statement describes CronJob in Kubernetes?

• A. CronJob runs a job on a predefined schedule.
• B. CronJob creates services.
• C. CronJob updates deployments.
• D. CronJob manages ConfigMaps.

Answer: (A)

CronJob is used to run batch-style tasks on a schedule. It defines a cron-like schedule and a template for a Job. When the schedule matches, the CronJob controller creates a new Job, which then launches pods to run the task to completion. That is why the statement describing CronJob as running a job on a predefined schedule is the best fit. CronJob itself does not create services, update deployments, or manage ConfigMaps; those functions are handled by other Kubernetes resources.
