The correct answer is C because a DaemonSet ensures that a copy of a pod runs on all (or some) nodes in a Kubernetes cluster. This is ideal for deploying background tasks like monitoring solutions across all nodes without manual intervention.

• DaemonSets are designed to run a copy of a pod on each node in the cluster, making them perfect for deploying monitoring solutions that need to be present on every node.
• Option A (StatefulSet) is incorrect because StatefulSets are used for applications that require stable, unique network identifiers or persistent storage, not for deploying across all nodes.
• Option B (Deployment Manager) is incorrect as it is a Google Cloud tool for deploying resources, not for managing pods across nodes in a Kubernetes cluster.
• Option D (SSH manual installation) is impractical for large clusters and does not leverage Kubernetes' orchestration capabilities.
