Correct answer & explanation
✓
Snapshot Standby mode, which converts the standby to a read-write database for testing and later converts it back to a physical standby, merging changes.
Active Data Guard allows the standby database to be open in read-only mode while applying redo, and Snapshot Standby allows converting a standby to a read-write testing mode temporarily before converting it back.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Snapshot Standby mode, which converts the standby to a read-write database for testing and later converts it back to a physical standby, merging changes.
Why this is correct
Snapshot Standby allows read-write operations for testing while preserving redo from the primary to be applied when reverted back to physical standby.
- ✗
Manual database cloning from Object Storage snapshots.
Why it's wrong here
Cloning from backups does not utilize Data Guard's real-time testing capabilities.
- ✗
Logical Standby mode with SQL Apply disabled permanently.
Why it's wrong here
Disabling SQL apply permanently stops synchronization, breaking the DR posture.
- ✗
Primary database switchover executed during peak business hours.
Why it's wrong here
Switchover impacts primary availability and is not a non-disruptive testing method.
