What is the name of the Kubernetes Deployment that ensures a single instance of a pod will run on each node?

PodSet
Singleton
NodePod
DaemonSet

The correct answer is: DaemonSet

The correct answer is DaemonSet. A DaemonSet is a Kubernetes resource that ensures that a specific pod runs on each node in a cluster. This is particularly useful for background tasks or system-level daemons that need to execute on every node, such as log collectors or monitoring agents. By using a DaemonSet, you can ensure that there is exactly one instance of the specified pod on every node, thus providing uniformity and ensuring that essential services are available across the cluster. The other terms mentioned do not refer to this functionality within Kubernetes. PodSet is not a recognized Kubernetes resource; Kubernetes primarily uses the concept of Deployments, ReplicaSets, and StatefulSets for managing groups of pods. Singleton does not accurately describe any existing Kubernetes object; it is more of a generic programming term that might apply to various contexts outside of Kubernetes. NodePod is also not an established Kubernetes resource and does not convey the intended functionality of ensuring a single pod instance per node.
