問題文

An administrator creates a restore point on a primary before a risky change and wants the standby to hold a matching marker without a manual step. What does the database do in this release?

選択肢

1. The marker is carried to the standby through the broker metadata and the apply process creates a guaranteed restore point there with a generated name
2. The marker is carried to the standby through the redo stream and the apply process creates a normal restore point there with a name derived from the original
3. The marker is carried to the standby through the recovery catalog and the apply process creates a normal restore point there with a generated numeric name
4. The marker is carried to the standby through the control file and the apply process creates a guaranteed restore point there with the same name as the original
