You are designing a disaster recovery strategy for an Oracle Autonomous Database (Serverless) instance. You need to ensure the database can failover to a remote region with minimal RPO. Which feature should you configure?
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
✓
Cross-Region Autonomous Data Guard
Autonomous Database supports cross-region Data Guard / Autonomous Data Guard, allowing you to configure a remote standby database with automatic failover capabilities.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
OCI Block Volume cross-region replication
Why it's wrong here
Autonomous Database storage is managed by Oracle and does not expose underlying block volumes for manual replication.
- ✓
Cross-Region Autonomous Data Guard
Why this is correct
Autonomous Data Guard provides automated disaster recovery for Autonomous Database across regions with zero or near-zero RPO/RTO.
- ✗
Manual RMAN incremental backups copied to Object Storage in the remote region
Why it's wrong here
Manual RMAN backups are not supported for Autonomous Database Serverless; automated backups are managed by Oracle.
- ✗
Database Express Export/Import scheduled via cron
Why it's wrong here
Export/Import is not a suitable DR strategy for meeting low RPO/RTO targets.
