1Z0-1067-25 Question 72
Select 2You manage a mission-critical application running on an Autonomous Transaction Processing database in Oracle Cloud Infrastructure (OCI). Your organization requires that the application remain available even if the primary OCI region suffers a complete outage. Which two actions should you take to ensure near-zero data loss and rapid failover to a secondary region?
- A
A. Configure Autonomous Data Guard with a physical standby in a different OCI region and set the protection mode to Maximum Availability.
- B
B. Enable cross-region replication for your OCI Object Storage buckets used for static content shared by the application.
- C
C. Schedule nightly backups of the primary database to a local block volume in the same Availability Domain (AD).
- D
D. Configure an active-active load balancer across Availability Domains within a single OCI region.
- E
E. Implement an OCI Health Check that monitors the primary region and triggers a manual switchover if an outage is detected.
Show answer and explanation
Correct answers: A, E
Explanation
To ensure continuous availability when a primary region becomes inaccessible, you must protect both your application data and the mechanism triggering a failover. Autonomous Data Guard with Maximum Availability helps minimize data loss, while a health check and switchover strategy detect outages quickly. Oracle� Maximum Availability Architecture (MAA) guidelines recommend multi-region deployments, fast failover, and near real-time replication (via Data Guard) for mission-critical workloads. For more details, refer to the official Oracle documentation on �Using Data Guard with Autonomous Databases� and Oracle Cloud Infrastructure best practices for high availability and disaster recovery.
- A. Correct.
A. Correct. Configuring Autonomous Data Guard with Maximum Availability ensures that your standby database in a different region remains closely synchronized with the primary, allowing near-zero data loss in failover scenarios.
- B. Incorrect.
B. Incorrect. While replicating object storage is important for preserving static files, it does not alone ensure near-zero data loss for transactional data or rapid failover for the database itself.
- C. Incorrect.
C. Incorrect. Storing backups in the same AD helps with recovery in case of local data corruption, but it does not protect against a region-wide outage. Additionally, only performing nightly backups could lead to potential data loss if the region fails mid-day.
- D. Incorrect.
D. Incorrect. An active-active configuration across Availability Domains in one region offers some protection against AD failure, but does not protect against an entire region outage. A multi-region strategy is required for true regional fault tolerance.
- E. Correct.
E. Correct. Monitoring a primary region with an automated health check and orchestrating a switchover to a secondary region is a standard practice for achieving high availability. While the switchover may still require some manual intervention, a proactive health check ensures you can fail over quickly when issues are detected.
