A recurring workload in Kubernetes is implemented with aCronJob, so the correct choice isD. A CronJob is a controller that createsJobson a schedule defined in standard cron format (minute, hour, day of month, month, day of week). This makes CronJobs ideal for periodic tasks like backups, report generation, log rotation, and cleanup tasks.

AJob(option A) is run-to-completion but is typically aone-timeexecution; it ensures that a specified number of Pods successfully terminate. Youcanuse a Job repeatedly, but something else must create it each time—CronJob is that built-in scheduler. Option B (“Batch”) is not a standard workload resource type (batch is an API group, not the object name used here). Option C (DaemonSet) ensures one Pod runs on every node (or selected nodes), which is not “recurring,” it’s “always present per node.”

CronJobs include operational controls that matter in real clusters. For example, concurrencyPolicy controls what happens if a scheduled run overlaps with a previous run (Allow, Forbid, Replace). startingDeadlineSeconds can handle missed schedules (e.g., if the controller was down). History limits (successfulJobsHistoryLimit, failedJobsHistoryLimit) help manage cleanup and troubleshooting. Each scheduled execution results in a Job with its own Pods, which can be inspected with kubectl get jobs and kubectl logs.

So the correct Kubernetes object for a recurring workload isCronJob (D): it provides native scheduling and creates Jobs automatically according to the defined cadence.
