問題文
A platform team runs stateful applications on Kubernetes and asks what a backup of one of those applications has to include so that it can be restored into a rebuilt cluster. What is the correct scope?
選択肢
- The container images of the application only because the data can be regenerated from the upstream systems after the restore finishes.
- The persistent volume data together with the Kubernetes objects that define the application so both can be recreated as a unit.
- The whole cluster including the control plane state because a namespace cannot be restored independently of the cluster it came from.
- The persistent volume data only because the cluster definitions are held in the source repository that the team already versions.
