A company uses AWS Direct Connect to connect its corporate network to multiple VPCs in the same AWS account and the same AWS Region. Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection. The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection.
What is the MOST scalable way to add VPCs with on-premises connectivity?
The most scalable way to add VPCs with on-premises connectivity is to create a transit gateway and attach the VPCs to it. Then, create a Direct Connect gateway and associate it with the transit gateway, and create a transit VIF to the Direct Connect gateway. This setup allows for a highly scalable architecture because the transit gateway can handle connections from multiple VPCs and offers flexibility for further expansion, including potential expansion to new regions. It simplifies the network routing and centralizes the management of the connections.
D for sure using DXGW with TGW allow you to also be flexible in case of expanding to new regions with more TGW in those regions.
D is correct. TGW and DXG provide the most scaling.
D - correct. When a company requires connectivity to multiple VPCs over AWS Direct Connect, a scalable solution is to use a transit gateway. A transit gateway is a hub that can interconnect multiple VPCs and VPN connections. The VPCs can communicate with each other over the transit gateway, and on-premises networks can communicate with the VPCs through the Direct Connect gateway. This solution provides a central point of management and simplifies the configuration of network routing. By associating the Direct Connect gateway with the transit gateway, traffic between the VPCs and the on-premises network can be routed through the Direct Connect connection.
I think that It's correct answer is D.
D no brainer
D is the more scalable.
D transit GW
D is much scalable
DDDDDDDDDDD
why so many and are wrong, or getting contradictory
Correct answer is D. 1 DxGW can connect to up to 6 TGW. Each TGW can connect to thousands of VPCs (5000 attachments).
I think that it's correct answer is D.
For sure D.
