Select 2Your company hosts critical production workloads on Oracle Cloud Infrastructure (OCI) but relies on AWS for data analytics. You need to establish a dedicated private connection with high throughput and low latency between the two clouds. Which two approaches or best practices should you consider for reliably configuring this connectivity?
- A
Procure an OCI FastConnect port and an AWS Direct Connect link through a third-party network service provider that supports both clouds.
- B
Use static routing on both the OCI and AWS sides to avoid complexities associated with dynamic routing protocols.
- C
Enable a single NAT gateway on OCI to route private traffic to AWS over the dedicated link.
- D
Establish BGP routing with route filtering to advertise only relevant subnets and maintain control over propagated routes.
Show answer and explanation
Correct answers: A, D
Explanation
To configure multicloud connectivity between OCI and AWS, you typically need a dedicated connection provided by FastConnect and AWS Direct Connect or a partner service that supports both. BGP is a key protocol used in these scenarios to handle dynamic routing and route filtering, ensuring that each cloud only sees the appropriate subnets. Refer to Oracle� documentation on FastConnect partner setups and AWS Direct Connect best practices for detailed guidance.
- A. Correct.
Correct. Many organizations use a third-party connectivity provider that can provision both OCI FastConnect and AWS Direct Connect for a unified private connection. This approach delivers dedicated bandwidth, reduced latency, and simplifies multicloud networking.
- B. Incorrect.
Incorrect. While static routes might seem simpler, large or dynamically changing environments benefit significantly from a dynamic routing protocol like BGP. BGP automatically updates routes and is considered a best practice for scalable, fault-tolerant multicloud architectures.
- C. Incorrect.
Incorrect. Using a NAT gateway in this scenario is typically reserved for outbound internet traffic. A dedicated private link to AWS should use private IP addresses, and NAT would break the end-to-end private connectivity model. This results in unnecessary complexity and potential performance overhead.
- D. Correct.
Correct. BGP is recommended for dedicated multicloud connections because it dynamically propagates routes, detects changes quickly, and allows granular control of which routes are shared (via route filtering). This helps mitigate potential routing conflicts across clouds.
