You are responsible for securing thekubeletcomponent in a Kubernetes cluster. Which of the following statements about kubelet security is correct?
Correct Answer: C
* Thekubeletis the primary agent that runs on each node in a Kubernetes cluster and communicates with the control plane. * Kubeletsupports TLS (Transport Layer Security)for both authentication and encryption when interacting with the API server. This is a core security feature that ensures secure node-to-control-plane communication. * Incorrect options: * (A) Kubelet does not run as a privileged container by default; it runs as a system process (typically systemd-managed) on the host. * (B) Kubelet does include built-in security features such asTLS authentication, authorization modes, and read-only vs secured ports. * (D) While kubelet interacts with the host system (e.g., cgroups, container runtimes), it does not inherently require root access for communication security; RBAC and TLS handle authentication.
