Your company has a single 1 Gbps AWS Direct Connect link to one AWS Region. It uses a single private virtual interface that connects to one VPC. You must add a redundant Direct Connect connection in the same Region and enable connectivity to additional Regions using the same pair of Direct Connect connections as you expand. Which solution satisfies these requirements?

The correct solution involves a Direct Connect gateway because it enables connectivity to multiple VPCs in the same or different Regions through a single Direct Connect connection. To achieve redundancy and future multi-Region connectivity, you need to provision a Direct Connect gateway, remove the existing private VIF (which is tied to a single VPC), create a second Direct Connect connection for redundancy, and then create new private VIFs on both connections, attaching them to the Direct Connect gateway. Finally, associate the Direct Connect gateway with the VPC. The incorrect options fail for various reasons: Keeping the existing private VIF and adding another private VIF on a new connection to the same VPC doesn't provide multi-Region capability and doesn't use a Direct Connect gateway for centralized management. Using a public virtual interface is incorrect as it's for public AWS services, not private VPC connectivity. While Transit Gateway can connect multiple VPCs, it's not the primary service for extending Direct Connect to multiple Regions; Direct Connect gateway is specifically designed for this purpose and is a more direct solution for the stated requirements.
