Cilium, Medium (Advanced), Architecture. https://k8wiz.com/uquiz/which-of-the-following-is-a-benefit-of-ciliums-ebpf-based-implementation-compared-to-iptables

- A. Wider compatibility with older Linux kernels
- B. Simpler configuration and management
- C. Better performance and scalability
- D. Native integration with Docker

**Answer:** Better performance and scalability

**Explanation:** A key benefit of Cilium's eBPF-based implementation compared to iptables is better performance and scalability. eBPF programs can make forwarding decisions more efficiently than iptables chains, especially as the number of rules grows. This results in lower latency and better throughput, particularly in large clusters with many services and network policies.
