Kubernetes Architecture and Core Components Questions

Fundamental architecture of Kubernetes and its core components: control plane design including API server, etcd distributed state store, scheduler, controller manager, and cloud controller manager; worker node components including kubelet, kube proxy, and the container runtime; core objects and abstractions such as pods, services, deployments, stateful sets, daemon sets, jobs, config maps, and secrets; cluster state management, service discovery, health checks, and self healing. Candidates should understand how components interact, data flow, failure modes, and how to design for availability and scalability at the component level.
