Amazon Web Services ANS-C01 Question Answer

A company has several AWS Site-to-Site VPN connections between an on-premises customer gateway and a transit gateway. The company's application uses IPv4 to communicate through the VPN connections.

The company has updated the VPC to be dual stack and wants to transition to using IPv6-only for new workloads. When the company tries to communicate through the existing VPN connections, IPv6 traffic fails.

Which solution will provide IPv6 support with the LEAST operational overhead?

Create a new Site-to-Site VPN connection that supports IPv6.

Create a new Site-to-Site VPN connection to a self-managed Amazon EC2 instance that runs open source software.

Update the existing Site-to-Site VPN connections to support IPv6.

Update the on-premises customer gateway's public IP address from IPv4 to IPv6.
