1Z0-1151-25 Question 3
Single answerA financial services company hosts its mission-critical database on Oracle Cloud Infrastructure (OCI) and runs its customer-facing web application in AWS. They need to ensure low-latency communication and throughput between application servers in AWS and the OCI database without exposing customer data to the public internet. Which option provides a recommended baseline for secure, high-speed connectivity in this multicloud environment?
- A
Establish a site-to-site IPSec VPN tunnel over the public internet between AWS and OCI
- B
Use Oracle Data Guard on AWS instances to replicate transaction logs back to OCI
- C
Set up a dedicated interconnection by pairing OCI FastConnect with AWS Direct Connect
- D
Rely on public SFTP for periodic data transfers between AWS and OCI
Show answer and explanation
Correct answer: C
Explanation
The recommended practice for ensuring secure, low-latency, and high-bandwidth connectivity between OCI and AWS is to leverage private interconnection options. By using OCI FastConnect and AWS Direct Connect, organizations can bypass the public internet and benefit from dedicated, predictable network performance. Refer to the official Oracle documentation on FastConnect (https://docs.oracle.com/en-us/iaas/Content/Network/Concepts/fastconnect.htm) and AWS documentation on Direct Connect (https://aws.amazon.com/directconnect/) for best practices and detailed setup steps.
- A. Incorrect.
Option 1 is incorrect. While IPSec VPN is a viable option for encrypting traffic, it relies on public internet connections, which may not meet the company� requirements for consistent low-latency or high throughput.
- B. Incorrect.
Option 2 is incorrect. Replicating transaction logs with Data Guard alone does not address the immediate need for a dedicated low-latency link. Data Guard is useful for disaster recovery, not continuous, high-bandwidth, real-time communication between clouds.
- C. Correct.
Option 3 is correct. Pairing OCI FastConnect with AWS Direct Connect creates a private, high-bandwidth connection over either dedicated or partner-managed circuits. This approach meets the high-throughput, low-latency, and security requirements for cross-cloud communication.
- D. Incorrect.
Option 4 is incorrect. While secure file transfers can help move data between clouds on a schedule, they do not provide a continuously available low-latency connection or real-time data exchange between the seen and the database.
