Reveal correct answer
Correct answer: D
A.
Metrics Server is the component responsible for collecting and storing metrics from Kubelets and serving them through the Kubernetes API. It is a core part of the resource metrics pipeline.
B.
API Server is where the Metrics Server exposes the metrics collected so that other components can query them. It's also a core part of the resource metrics pipeline.
C.
Kubelet is the agent that runs on each node in the Kubernetes cluster and is responsible for collecting performance metrics such as CPU and memory usage for Pods and Nodes. These metrics are sent to the Metrics Server.
D.
Heapster is now deprecated and is not a component of the core resource metrics pipeline in modern Kubernetes clusters. The core resource metrics pipeline typically involves the Metrics Server, Kubelet, API Server, and other components like the Horizontal Pod Autoscaler (HPA) for autoscaling based on metrics.
