The correct answer is that the Direct Connect Gateway facilitates Direct Connect connections to multiple VPCs, while the Transit Gateway connects VPCs and on-premises networks.

Direct Connect Gateway is specifically designed to enable customers to create private connections from their on-premises networks directly into AWS. This includes the ability to connect to multiple Virtual Private Clouds (VPCs) within the same region or across different regions, utilizing the AWS Direct Connect service. This is particularly useful for organizations that want to streamline their network architecture and improve the performance and security of their connections.

On the other hand, Transit Gateway acts as a central hub that connects multiple VPCs and on-premises networks, enabling seamless and scalable communication between them. It provides a way to simplify network management by allowing routing and network topologies to be managed from a single point.

Therefore, the distinct roles of the Direct Connect Gateway in managing dedicated connections to VPCs and the Transit Gateway’s function in interconnecting VPCs and on-premises networks highlight the differences between these two services in AWS networking.

Contextually, while other options may focus on aspects such as latency, bandwidth, or the type of connections (private vs public), they don't accurately capture the core functionalities and use cases
