Linux Foundation Kubernetes and Cloud Native KCSA Question # 13 Topic 2 Discussion

etcdis Kubernetes’key-value storeforcluster state.

Stores: ConfigMaps, Secrets, Pod definitions, Deployments, RBAC policies, and metadata.

Exact extract (Kubernetes Docs – etcd):

“etcd is a consistent and highly-available key-value store used as Kubernetes’ backing store for all cluster data.”

Clarifications:

B: Logs/metrics are handled by logging/monitoring solutions, not etcd.

C: Secrets may be stored here but encoded in base64, not specifically "usernames/passwords" as primary use.

D: Persistent Volumes are external storage, not stored in etcd.
