Oracle Cloud Infrastructure 2022 Architect Professional — Question 24

A retail company has recently adopted a hybrid architecture. They have the following requirements for their end-to-end connectivity model between their on-premises data center and the Oracle Cloud Infrastructure (OCI) region.
Highly available connection with service level redundancy
Dedicated network bandwidth with low latency
Which connectivity setup is the most cost-effective solution for this scenario?

Answer options

• A. Set up the FastConnect virtual circuit as your primary connection, and a second FastConnect virtual circuit as a backup connection. Make sure your FastConnect physical connectivity is redundant. Use a single edge device in your on-premises data center for each connection. From your edge device, advertise more specific routes via the primary FastConnect virtual circuit, and less specific routes through the backup FastConnect virtual circuit.
• B. Set up the FastConnect virtual circuit as your primary connection, and an IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through the FastConnect virtual circuit, and less specific routes through the backup IPSec VPN path.
• C. Set up IPSec VPN as your primary connection, and a second IPSec VPN as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes via the primary IPSec VPN, and less specific routes through the backup IPSec VPN.
• D. Set up IPSec VPN as your primary connection, and a FastConnect virtual circuit as a backup connection. Use separate edge devices in your on-premises data center for each connection. From your edge devices, advertise more specific routes through the IPSec VPN, and less specific routes through the backup FastConnect virtual circuit.

Correct answer: A

Explanation

The correct answer is A because it provides a primary connection with FastConnect, which is designed for high availability and low latency, and a redundant backup FastConnect virtual circuit, ensuring service level redundancy. Options B, C, and D utilize IPSec VPNs, which may not offer the same dedicated bandwidth and low latency as FastConnect, making them less cost-effective for the requirements stated.
