1Z0-997-26 High Availability And Disaster Recovery Practice Question
You are managing an Oracle Base Database Service instance configured with Data Guard in OCI. Due to a severe networking anomaly, the standby database falls significantly behind in applying redo. You decide to rebuild the standby database from an incremental backup taken on the primary. Which Recovery Manager (RMAN) command or process is used to synchronize the standby with the new incremental backup?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Apply an incremental backup from SCN on the primary database to the standby database using RMAN.
RMAN incremental backup from SCN allows you to apply an incremental backup taken from the primary database directly to the standby database to catch it up without having to recreate the entire standby from scratch.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Execute a complete cold restore of all datafiles using FTP over port 21.
Why it's wrong here
Cold restores via FTP are insecure, manual, and unnecessary when RMAN incremental catch-up is available.
- ✗
Reboot the OCI compute host using the OCI console 'Reset' button.
Why it's wrong here
Rebooting a compute instance does not resolve database redo application gaps.
- ✓
Apply an incremental backup from SCN on the primary database to the standby database using RMAN.
Why this is correct
RMAN incremental backups from SCN can catch up a lagging standby database efficiently.
- ✗
Run 'ALTER DATABASE CONVERT TO SNAPSHOT STANDBY' and drop all tablespaces.
Why it's wrong here
Dropping tablespaces destroys data and does not solve an incremental redo lag.
