Option A is correct because creating a FastConnect virtual circuit with Microsoft Azure as the provider to establish a private interconnect between the application tier running in the Azure Virtual Network and the OCI VCN that contains the Oracle Databases is the most-fault tolerant and secure solution for this customer. This option provides low latency, high throughput, and consistent network performance across the clouds. It also avoids exposing the traffic to the public internet, which enhances security and reliability12.
Option B is incorrect because creating an encrypted, Virtual Private Network connection between the Microsoft Azure Virtual Network that contains the application tier and the OCI Virtual Cloud Network (VCN) that contains the Oracle Databases is not as fault-tolerant and secure as option A.
This option relies on the public internet for connectivity, which can introduce latency, bandwidth limitations, and security risks12.
Option C is incorrect because using an OCI Virtual Cloud Network remote peering connection to create a remote network connection between the application tier running in Microsoft Azure Virtual Network and Oracle Databases running in the OCI Virtual Cloud Network (VCN) is not possible. Remote peering connections can only be used to connect two VCNs within the same region or across regions within OCI. They cannot be used to connect a VCN with a VNet in another cloud provider3.
