1Z0-1123-25 Question 49
Select 2Your organization needs to replicate multiple on-premises Oracle Databases to Oracle Cloud Infrastructure (OCI) for a phased migration. The team wants near real-time data availability in the cloud for reporting and testing, with minimal downtime during cutover. Additionally, they have limited bandwidth over the existing VPN connection. Which two actions should you take to meet these replication and execution requirements?
- A
Use Oracle GoldenGate to continuously replicate changes from on-premises databases to OCI, ensuring near real-time data movement.
- B
Rely on daily incremental backups to transfer updates from the on-premises databases to Oracle Cloud Infrastructure.
- C
Establish a FastConnect link to provide higher and more consistent network throughput for the replication process.
- D
Use OCI Data Transfer Service to ship data on physical devices for daily transaction replication to the cloud.
- E
Over-provision on-premises network bandwidth to handle replication traffic without modifying the existing network setup.
Show answer and explanation
Correct answers: A, C
Explanation
In this scenario, near real-time data replication and minimal downtime are key objectives. Oracle GoldenGate is commonly used to continually replicate transactions from on-premises Oracle Databases to OCI. Establishing FastConnect helps ensure consistent, high-bandwidth network connectivity, avoiding the limitations of standard Internet-based VPN links. Refer to Oracle Cloud Infrastructure documentation on migration best practices and GoldenGate architecture for guidance on configuring and managing continuous replication workloads efficiently.
- A. Correct.
Correct. Oracle GoldenGate is a recommended solution for near real-time replication. It captures and applies data changes continuously, resulting in minimal downtime and better data consistency.
- B. Incorrect.
Incorrect. While incremental backups can capture changes, they are not near real-time. This approach could increase downtime or data lag, which does not align with the need for continuous replication.
- C. Correct.
Correct. FastConnect provides dedicated, high-bandwidth connectivity between on-premises and OCI. This stable throughput is especially important for near real-time replication solutions like GoldenGate.
- D. Incorrect.
Incorrect. OCI Data Transfer Service is best for migrating large initial data sets offline. It is not designed for continuous daily replication of transactional changes.
- E. Incorrect.
Incorrect. Simply over-provisioning network bandwidth on-premises might not guarantee stable throughput or solve latency issues. Dedicated connectivity solutions like FastConnect are more reliable for real-time replication.
