Answer: Deploy a transit gateway and a new accelerated Site-to-Site VPN connection.
To address the issue of excessive latency in the network path used by the Site-to-Site VPN connections, the most effective solution would be to deploy a transit gateway and a new accelerated Site-to-Site VPN connection. AWS Transit Gateway simplifies network architecture and scales horizontally with your network. It allows you to connect thousands of VPCs and on-premises networks in a hub-and-spoke model, which can significantly reduce latency by optimizing the path that traffic takes between your VPCs and on-premises networks. Additionally, an accelerated Site-to-Site VPN connection can provide lower latency by leveraging the AWS global network infrastructure. This solution directly addresses the root cause of the latency issue by optimizing the network path and leveraging AWS's global network for better performance. Option A, using AWS Global Accelerator, is not suitable for this scenario as it is designed to improve the availability and performance of applications for end users, not for optimizing the network path between on-premises environments and VPCs. Option C, replacing the existing VPN connections with IPv6, does not directly address the latency issue. Option D, replacing the VPN connections with AWS PrivateLink, is not applicable as PrivateLink is used for securely accessing services hosted on AWS, not for connecting on-premises networks to VPCs.

A company has established multiple AWS Site-to-Site VPN connections linking its on-premises environment to several VPCs, utilizing virtual private gateways and IPv4 addressing. Internal applications hosted in the VPCs are experiencing performance issues, with users reporting slow response times. A network engineer identifies significant latency along the network path used by the VPN connections.
What solution should the network engineer implement to address the excessive latency?
A
Use AWS Global Accelerator to deploy an accelerator on the existing Site-to-Site VPN connections.
B
Deploy a transit gateway and a new accelerated Site-to-Site VPN connection.
C
Replace the existing Site-to-Site VPN connections with new Site-to-Site VPN connections that use IPv6.
D
Replace the existing Site-to-Site VPN connections with AWS PrivateLink connections.
