Which Kubernetes object is used to schedule periodic tasks?

• A. Job
• B. CronJob
• C. DaemonSet
• D. StatefulSet

Answer: (B)

Scheduling periodic tasks in Kubernetes is handled by a CronJob. A CronJob defines a schedule with a cron expression and automatically creates a Job at each scheduled time. That Job then runs to completion, handling retries and parallelism as configured. This makes CronJob ideal for recurring tasks like backups, reports, or cleanup tasks. A plain Job runs once (or a fixed number of completions) when created, not on a repeating schedule. DaemonSet keeps a pod on every node, and StatefulSet manages stateful workloads with stable identities and storage. So CronJob is the correct choice for periodic execution.
