Which object is recommended for managing jobs that need to run multiple times according to a batch process?

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

Answer: (B)

When you have work that should run to completion as part of a batch, the Job resource is the right choice. A Job manages one or more Pods that perform work and exit when finished. You can configure how many successful completions are needed (completions) and how many Pods run in parallel (parallelism). This makes it ideal for a batch task that needs to be executed multiple times within a single logical job—the system will keep creating pods until the required number of successful completions is reached, retrying failed pods up to the backoff limit if needed. CronJob is for scheduling such work to run at specific times, wrapping a Job to execute on a schedule, but the core mechanism for the batch that runs to completion is the Job. DaemonSet places a pod on every node for node-wide, long-running tasks; StatefulSet is for stateful workloads requiring stable identities and storage.
