Question

A company operates workloads in a Transit Gateway in us-east-1 and another Transit Gateway in eu-west-1. They have a single Direct Connect location in the US with a 10 Gbps dedicated connection. The network team must allow on-premises networks to reach VPCs attached to both Transit Gateways over the Direct Connect connection, while minimizing the number of virtual interfaces required. Which implementation meets these requirements?

Accepted Answer

Create one transit VIF, associate it with a Direct Connect gateway, and associate both Transit Gateways to that Direct Connect gateway with allowed prefixes configured.

Answer

Create two private VIFs, one associated with a Direct Connect gateway for us-east-1 and one for eu-west-1, and attach each gateway to the respective Transit Gateway.

Answer

Create a transit VIF for each Transit Gateway and associate both to a single Direct Connect gateway that peers the two Transit Gateways together.

Answer

Create one public VIF, associate it with a Direct Connect gateway, and route to both Transit Gateways using BGP advertised prefixes.
