Answer: 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.
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 current bandwidth limitation of 1.25 Gbps and the need for a temporary solution. Option A is not feasible because AWS does not allow increasing the bandwidth quota for Site-to-Site VPN connections beyond their standard limits. Option B suggests upgrading the customer gateway device, but this does not address the inherent bandwidth limitations of the VPN connection itself. Option C proposes creating additional Site-to-Site VPN connections and using ECMP routing to aggregate their bandwidth. This is a viable solution as it effectively increases the total available bandwidth by utilizing multiple connections in parallel. Option D introduces the use of a transit gateway, which, while a powerful feature for managing multiple VPCs and VPN connections, is more complex and not necessarily required for simply increasing bandwidth in this scenario. Therefore, the most straightforward and effective solution is to create additional Site-to-Site VPN connections and configure ECMP routing, making option C the correct choice.

What steps should the network engineer take to enhance 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.
