# Which annotation lets two LoadBalancer Services get the same IP from Cilium LB IPAM?

Cilium, Easy (Beginner), Networking. https://k8wiz.com/uquiz/which-annotation-lets-two-loadbalancer-services-get-the-same-ip-from-cilium-lb-ipam

- A. lbipam.cilium.io/ips
- B. io.cilium/shared-service
- C. lbipam.cilium.io/pool-name
- D. lbipam.cilium.io/sharing-key

**Answer:** lbipam.cilium.io/sharing-key

**Explanation:** Services with the same lbipam.cilium.io/sharing-key value share an IP as long as their ports don't conflict. The lbipam.cilium.io/ips annotation requests specific addresses but doesn't make Services share one. Sharing across namespaces also needs the lbipam.cilium.io/sharing-cross-namespace annotation on both Services.
