After etcd data corruption, HR restores from a recent etcd snapshot and API objects reappear. What skill does this exercise demonstrate?
Select an answer to reveal the explanation.
Short Explanation
When etcd's ledger is trash, you restore from last night's snapshot—the cluster's saved game—so API objects come back. That restore drill is core recovery muscle.
Full Explanation
etcd holds cluster state. After corruption or catastrophic loss, administrators restore from an etcd snapshot/backup and bring the API back with historical objects. Recreating kube-proxy, scaling Deployments, or deleting static manifests does not regenerate authoritative etcd state.
