# Which Cilium resource tells nodes to answer ARP requests for LoadBalancer Service IPs on the local network?

Cilium, Easy (Beginner), Networking. https://k8wiz.com/uquiz/which-cilium-resource-tells-nodes-to-answer-arp-requests-for-loadbalancer-service-ips-on-the-local-network

- A. CiliumLoadBalancerIPPool
- B. CiliumL2AnnouncementPolicy
- C. CiliumBGPAdvertisement
- D. CiliumNodeConfig

**Answer:** CiliumL2AnnouncementPolicy

**Explanation:** A CiliumL2AnnouncementPolicy selects which Services are announced, from which nodes and on which interfaces, and the elected node answers ARP (or NDP) for their IPs. A CiliumLoadBalancerIPPool only allocates the addresses; without an announcement policy, nothing on the LAN can reach them.
