問題文
A team needs a copy of a production Autonomous AI Database for a reporting workload. The copy must contain the data and must be kept close to the source without manual export steps, and reporting only reads. Which clone type fits?
選択肢
- A metadata clone, because reporting needs the schema rather than the data, and the rows are loaded later by a separate job.
- A full clone, because it is the only type that contains the data, and refreshing it later is done by taking a new full clone and switching the reporting connection to it when the copy is ready.
- A snapshot standby, because it opens in read-write mode.
- A refreshable clone, which is a read-only full copy that can be refreshed with the data of the source.
