問題文
An administrator is writing the backup routine for a production Oracle Analytics Cloud instance and has to state in the runbook how many snapshots the service will hold and what happens to the ones beyond that. Which statement matches the documentation?
選択肢
- The service keeps up to 40 snapshots online, and anything beyond that is dropped oldest first as soon as a new snapshot pushes the instance over the ceiling.
- The service places one snapshot per week online, and older ones are folded into a single archive that the console rebuilds when a restore is requested.
- The service places no ceiling on online snapshots, and the practical limit is the download limit of the browser that the administrator uses to export them.
- The service keeps up to 40 snapshots online, and anything beyond that has to be exported to offline storage, meaning a local file system or an Oracle Cloud storage bucket that the administrator sets up.
