Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Perform a Switchover operation from the standby database details page.
Why it's wrong here
A switchover is a role reversal meant for planned activities where the primary database is still healthy.
- ✗
Delete the Data Guard association and create a new primary database from a backup.
Why it's wrong here
This causes unnecessary downtime and data loss compared to using the built-in Data Guard failover action.
- ✓
Perform a Failover operation from the standby database details page.
Why this is correct
A failover operation is used during an unplanned outage of the primary database to transition the standby to the primary role.
- ✗
Run RMAN restore commands directly on the standby host operating system.
Why it's wrong here
Data Guard role transitions are managed natively through the OCI Console or API without manual RMAN operations.
