Answer: Create a transit gateway. Attach the VPCs to the transit gateway. Create several additional Site-to-Site VPN connections that terminate on the transit gateway. Configure equal-cost multi-path (ECMP) routing to use all the VPN connections simultaneously.
The question revolves around improving the bandwidth of a temporary AWS Site-to-Site VPN connection before the implementation of a Direct Connect connection. The key points to consider are the limitations of a single VPN connection and the potential solutions to increase bandwidth. Option A is not feasible because AWS does not allow increasing the bandwidth quota for a single Site-to-Site VPN connection beyond its maximum capacity. Option B suggests upgrading the customer gateway device, but this does not address the inherent bandwidth limitation of a single VPN connection. Option C proposes creating additional VPN connections and using ECMP routing, which is a valid approach to aggregate bandwidth across multiple connections. However, it does not utilize the most efficient AWS service for this purpose. Option D introduces the use of a transit gateway, which is designed to simplify network architecture and improve scalability. By attaching the VPCs to a transit gateway and creating multiple VPN connections that terminate on it, the network engineer can effectively use ECMP routing to aggregate bandwidth across all VPN connections, thus improving the overall bandwidth. Therefore, the most effective solution is to use a transit gateway with multiple VPN connections and ECMP routing.

What steps should the network engineer take to increase the bandwidth of the Site-to-Site VPN connection, which is currently limited to 1.25 Gbps, prior to the deployment of the 10 Gbps AWS Direct Connect connection?
A
Contact AWS Support to request a bandwidth quota increase for the existing Site-to-Site VPN connection.
B
Discuss the issue with the hardware vendor. Buy a bigger and more powerful customer gateway device that has faster encryption and decryption capabilities.
C
Create several additional Site-to-Site VPN connections that terminate on the same virtual gateway. Configure equal-cost multi-path (ECMP) routing to use all the VPN connections simultaneously.
D
Create a transit gateway. Attach the VPCs to the transit gateway. Create several additional Site-to-Site VPN connections that terminate on the transit gateway. Configure equal-cost multi-path (ECMP) routing to use all the VPN connections simultaneously.
