Selected Answer: A

A!! The main purpose of a Kubernetes DaemonSet is to ensure that a copy of a specified pod runs on all (or selected) nodes in a cluster. DaemonSets are ideal for deploying background services or node-local tools, such as logging agents, monitoring tools, or network helpers, that need to be present on every node to provide essential cluster functionality. The DaemonSet controller automatically adds the designated pod to new nodes joining the cluster and removes it from nodes that are removed, maintaining the desired state across the cluster
