Oracle Cloud Infrastructure 2022 Architect Professional — Question 46

A retail company has several on-premise data centers which span multiple geographical locations. They plan to move many of their business critical applications to Oracle Cloud Infrastructure (OCI). These applications require highly available network connections between on-premises and OCI.
Which option provides the highest level of redundancy?

Answer options

• A. Set up both Site-to-Site VPN and Fast Connect connections from OCI to separate edge devices on-premises.
• B. Set up Site-to-Site VPN connection with two redundant tunnels from the on-premises edge device to OCI.
• C. Use either a Site-to-Site VPN or FastConnect connection to connect to an on-premises edge device, since OCI provides network redundancy by default.
• D. Set up Fast Connect with the colocation with Oracle option, and a compatible edge device on- premises.
• E. Use transit routing by deploying a hub Virtual Cloud Network (VCN) in OCI peered with application VCNs as spokes, and with an on-premises edge device with two redundant tunnels in Site-to-Site VPN.

Correct answer: A

Explanation

Option A provides the highest level of redundancy by combining both Site-to-Site VPN and Fast Connect connections, ensuring that if one connection fails, the other remains operational. The other options, while they offer some level of redundancy, do not match the dual-path approach of option A, which is crucial for maintaining highly available network connections.
