Network Design

A company uses AWS Direct Connect to link its corporate network with multiple VPCs in the same AWS account and AWS Region. Every VPC has its own private VIF and virtual LAN on the Direct Connect connection. The company has expanded and will soon exceed the per-connection limit for VPCs and private VIFs.

What is the MOST scalable way to add VPCs with connectivity to the on-premises network?

  • 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.
Explanation

AWS Transit Gateway provides a hub for many VPC attachments, avoiding a separate private virtual interface and VLAN for each VPC. A Direct Connect gateway can be associated with that transit gateway, and a transit virtual interface connects the Direct Connect connection to the gateway, providing on-premises connectivity to the attached VPCs at scale.
