Question
A company hosts its IT infrastructure in an on-premises data center. The company wants to migrate the infrastructure to the AWS Cloud in phases. A network engineer wants to set up a 10 Gbps AWS Direct Connect dedicated connection between the on-premises data center and VPCs. The company's network provider needs 3 months to provision the Direct Connect connection. In the meantime, the network engineer implements a temporary solution by deploying an AWS Site-to-Site VPN connection that terminates to a virtual private gateway. The network engineer observes that the bandwidth of the Site-to-Site VPN connection is capped at 1.25 Gbps despite a powerful customer gateway device. What should the network engineer do to improve the VPN connection bandwidth before the implementation of the Direct Connect connection?
Options
- AContact AWS Support to request a bandwidth quota increase for the existing Site-to-Site VPN
- BDiscuss the issue with the hardware vendor. Buy a bigger and more powerful customer gateway
- CCreate several additional Site-to-Site VPN connections that terminate on the same virtual
- DCreate a transit gateway. Attach the VPCs to the transit gateway. Create several additional Site-

Explanation
Per VPN connection, you can achieve 1.25 Gbps of throughput and 140,000 packets per second. When terminating the VPN connections in the Transit Gateway, you can use Equal Cost Multi- Path (ECMP) routing to get a higher VPN bandwidth by aggregating multiple VPN tunnels. To use ECMP, you need to configure dynamic routing in the VPN connections – ECMP is not supported using static routing. https://docs.aws.amazon.com/whitepapers/latest/aws-vpc-connectivity-options/aws-transit- gateway-vpn.html
