Cilium, Medium (Advanced), Networking. https://k8wiz.com/uquiz/what-is-ciliums-bpf-based-kube-proxy-replacement

- A. A feature that uses eBPF to implement Kubernetes services more efficiently
- B. A replacement for the entire Kubernetes control plane
- C. A proxy that intercepts all pod traffic
- D. A load balancer for external traffic

**Answer:** A feature that uses eBPF to implement Kubernetes services more efficiently

**Explanation:** Cilium's kube-proxy replacement is a feature that uses eBPF to implement Kubernetes services more efficiently than the standard kube-proxy. It provides the same functionality (ClusterIP, NodePort, ExternalIPs, LoadBalancer) but with better performance and additional features like direct server return and socket-based load balancing.
