A. kubelet acts as the primary API component that stores and manages cluster state information.

B. kubelet manages the container runtime and ensures that all Pods scheduled to the node are running as expected.

C. kubelet configures networking rules on each node to handle traffic routing for Services in the cluster.

D. kubelet monitors cluster-wide resource usage and assigns Pods to the most suitable nodes for execution.

A. Pods can communicate with all Pods without NAT.

B. Pods can only communicate with Pods exposed via a Service.

C. The Pod IP is only visible inside a Pod.

D. The Service IP is used for the communication between Services.

A. The ability to log network security events.

A. Kustomize is designed for installing new applications only, while Helm is intended for managing ongoing application upgrades.

B. Kustomize overlays configurations directly without templates, while Helm relies on templates to manage reusable charts.

C. Kustomize is mainly used for creating Helm charts themselves, whereas Helm is used for deploying those charts into clusters.

D. Kustomize handles external application dependencies automatically, whereas Helm requires manual dependency tracking.
