Connect AWS Direct Connect to Multiple VPCs in Different Regions

Answer - D.

The AWS documentation mentions the following.

You can use an AWS Direct Connect gateway to connect your AWS Direct Connect connection over a private virtual interface to one or more VPCs in your account that are located in the same or different regions.

You associate a Direct Connect gateway with the virtual private gateway for the VPC, and then create a private virtual interface for your AWS Direct Connect connection to the Direct Connect gateway.

You can attach multiple private virtual interfaces to your Direct Connect gateway.

The correct answer is D. AWS Direct Connect gateway.

AWS Direct Connect is a service that enables users to establish a dedicated network connection from their on-premises data center or office to AWS. The service provides high bandwidth, low-latency connectivity and can be used to create private connections between AWS and on-premises infrastructure.

AWS Direct Connect supports connecting to VPCs in the same region as well as in different regions, using private virtual interfaces (VIFs). To connect your Direct Connect connection over a private VIF to one or more VPCs in your account, you can use an AWS Direct Connect gateway.

An AWS Direct Connect gateway is a horizontally scalable, redundant, and highly available virtual router that connects Direct Connect private VIFs to VPCs. It acts as a traffic hub and provides routing between Direct Connect VIFs and VPCs. It can be used to connect multiple VPCs in the same or different regions to a single Direct Connect connection, making it easier to manage connectivity to multiple VPCs.

AWS Direct Connect gateway supports two types of VPC attachments: transit and non-transit. A transit VPC attachment enables traffic to flow between a VPC and other VPCs or on-premises networks, while a non-transit VPC attachment enables traffic to flow only between a VPC and an on-premises network.

In summary, to connect your AWS Direct Connect connection over a private virtual interface to one or more VPCs in your account that are located in the same or different regions, you can use an AWS Direct Connect gateway.
