Ensures a copy of a pod runs on all or selected nodes
Manages stateful applications with unique network identities
Runs a finite task to completion
Runs jobs on a time-based schedule
Automatically scales pod replicas based on CPU/memory metrics
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Deployment: Manage stateless applications with rolling updates and rollbacks
Correct matches: Deployment manages stateless apps with rolling updates; StatefulSet handles stateful apps with stable identities; DaemonSet runs a pod on every node. Common confusions: mixing Deployment with DaemonSet (one per node vs. stateless management) and StatefulSet with Jobs (stateful vs. batch).
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Deployment: Manage stateless applications with rolling updates and rollbacks
Why this is correct
Deployments are designed for stateless apps, providing declarative updates and easy rollback.
StatefulSet: Manage stateful applications that require stable network identities and persistent storage
Why this is correct
StatefulSets handle stateful workloads needing stable identities and persistent volumes.
DaemonSet: Ensure a copy of a pod runs on each node in the cluster
Why this is correct
DaemonSets guarantee one pod per node, ideal for cluster-wide services like logging.
Deployment: Ensure one pod per node in the cluster
Why it's wrong here
Incorrect — this describes a DaemonSet, not a Deployment.
StatefulSet: Run a batch job to completion
Why it's wrong here
Incorrect — batch jobs are managed by Job or CronJob, not StatefulSet.
