Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 59
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

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?

  • A. Provision a new Direct Connect connection to handle the additional VPCs. Use the new connection to connect additional VPCs.
  • B. Create virtual private gateways for each VPC that is over the service quota. Use AWS Site-to-Site VPN to connect the virtual private gateways to the corporate network.
  • C. Create a Direct Connect gateway, and add virtual private gateway associations to the VPCs. Configure a private VIF to connect to the corporate network.
  • D. Create a transit gateway, and attach the VPCs. Create a Direct Connect gateway, and associate it with the transit gateway. Create a transit VIF to the Direct Connect gateway.

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.

Correct answer is D. 1 DxGW can connect to up to 6 TGW. Each TGW can connect to thousands of VPCs (5000 attachments).

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.
