1Z0-1151-25 Question 15
Select 2A large retail enterprise currently hosts its e-commerce platform on AWS but is migrating its backend Oracle databases to Oracle Cloud Infrastructure (OCI) to improve performance and reduce costs. They want to ensure minimal downtime, real-time data exchange, and consistent user management across both clouds. Which two approaches should they implement as part of a robust multicloud solution?
- A
Use OCI Data Transfer Appliance daily to move all historical data from AWS to OCI for near real-time replication
- B
Establish a dedicated connection using Oracle FastConnect integrated with AWS Direct Connect for low-latency networking
- C
Leverage Oracle Data Guard to replicate from AWS RDS MySQL directly to an Oracle Autonomous Database in OCI
- D
Integrate AWS and OCI with the same federated identity provider for centralized access management
Show answer and explanation
Correct answers: B, D
Explanation
When implementing a multicloud strategy, enterprises often use a dedicated private network connection (FastConnect with AWS Direct Connect) for secure, low-latency communication between clouds. For user management, integrating both clouds with a single enterprise identity source simplifies access control and enforces consistent security policies. For more details, refer to Oracle Cloud Infrastructure documentation on FastConnect (docs.oracle.com/en-us/iaas/Content/Network/Concepts/fastconnect.htm) and identity federation (docs.oracle.com/en-us/iaas/Content/Identity/Concepts/federation.htm).
- A. Incorrect.
Incorrect. OCI Data Transfer Appliance is designed for bulk data migration from on-premises environments and is not intended for continuous or near real-time replication from AWS. Relying on daily transfers would also not satisfy the minimal downtime requirement.
- B. Correct.
Correct. Setting up a low-latency private link between OCI and AWS using Oracle FastConnect and AWS Direct Connect is a recommended network architecture for multicloud scenarios. This ensures reliable and efficient data exchange, helps minimize latency, and supports business-critical applications.
- C. Incorrect.
Incorrect. Oracle Data Guard does not replicate from MySQL to an Oracle Database. Data Guard requires an Oracle-to-Oracle setup. Attempting to use it for replication across different database engines (RDS MySQL to Oracle) is not supported.
- D. Correct.
Correct. Federating both clouds with the same identity provider enables seamless user management and single sign-on, reducing administrative overhead and improving security across both OCI and AWS environments.
