問題文

While creating the Exadata Infrastructure resource, the team debates whether the region can be revisited after the first databases are running. What is true of the region and availability domain for that resource?

選択肢

1. They are set per container database, so different containers in the same infrastructure can sit in different availability domains.
2. They are inherited from the first VM cluster that is created inside the resource, so the choice is deferred until the cluster is defined.
3. They are picked when the resource is created and can be changed later with a move operation, so the choice can follow the latency requirements as they change, and no rebuild is needed.
4. They are chosen when the resource is created and cannot be changed afterwards, so the choice has to match the latency and residency requirements up front.
