True or false: Transit Gateway in AWS fully automates routing so that no manual configuration is required.

The statement regarding Transit Gateway in AWS is false. While Transit Gateway does simplify the routing process and allows for central management of network traffic between multiple Virtual Private Clouds (VPCs) and on-premises networks, it does not eliminate the need for manual configuration entirely.

For instance, when using Transit Gateway, users must still define how VPCs and other networks connect to the gateway by creating attachments for each network that needs to communicate. Additionally, routing tables need to be configured to dictate the flow of traffic, specifying which destination networks can be reached through the Transit Gateway.

This nuance is essential for understanding the operational requirements surrounding AWS Transit Gateway and highlights that while it offers substantial automation benefits, it still requires some initial configuration and management to tailor the networking environment according to specific use cases or organizational needs.
