1Z0-1067-25 Question 70
Select 2You are an OCI Cloud Ops Professional responsible for implementing business continuity for a mission-critical e-commerce platform running in one region. The platform uses multiple compute instances fronted by an OCI load balancer, and an Autonomous Database for data storage. The goal is to maintain minimal downtime in the event of a regional outage while ensuring zero data loss. Which two actions should you take to meet these requirements with minimal manual intervention?
- A
A. Configure Oracle Data Guard to maintain a standby Autonomous Database in a secondary region.
- B
B. Set up an OCI Traffic Management steering policy that redirects traffic to the secondary region if the primary region becomes unreachable.
- C
C. Increase the shape of compute instances in the primary region to handle failover loads more effectively.
- D
D. Deploy the load balancer only across multiple Availability Domains in the primary region.
- E
E. Use the same Block Volume in the primary region for synchronous replication to the secondary region.
Show answer and explanation
Correct answers: A, B
Explanation
By using Oracle Data Guard with Autonomous Database and an OCI Traffic Management steering policy, you ensure data is continuously replicated to a standby database in another region, and traffic is automatically redirected if the primary region fails. This aligns with OCI best practices for high availability and disaster recovery, as described in the official OCI documentation for multi-region architectures and Data Guard configurations.
- A. Correct.
A. Correct. Enabling Oracle Data Guard for Autonomous Database provides synchronous or near-synchronous replication to a standby database, ensuring minimal or zero data loss in the event of a regional outage.
- B. Correct.
B. Correct. An OCI Traffic Management steering policy can detect if the primary region is unavailable and automatically route requests to the secondary region, minimizing manual intervention.
- C. Incorrect.
C. Incorrect. Simply increasing the shape of compute instances in the primary region will not provide redundancy if the entire region fails. It may help with performance in the primary region, but offers no business continuity across regions.
- D. Incorrect.
D. Incorrect. Deploying a load balancer across multiple Availability Domains in a single region protects against AD failures but does not address a full regional outage. A second region must also have a load balancer and a traffic management mechanism.
- E. Incorrect.
E. Incorrect. Block Volumes do not provide native cross-region replication for data with zero data loss, and it does not address database-level business continuity requirements.
