- A. Hubble
- B. Cilium agent
- C. kvstore
- D. Cilium Operator

**Answer:** kvstore

**Explanation:** Cilium uses a key-value store (kvstore) to distribute security identities and other cluster-wide information across all nodes. This can be etcd or Kubernetes CRDs, depending on the configuration. The kvstore ensures that all Cilium agents have a consistent view of identities, which is crucial for policy enforcement.
