Answer: Create a transit gateway in us-east-1 and in us-east-2. Attach the existing VPC and the new VPC to each transit gateway. Create a new Site-to-Site VPN connection to each transit gateway with IPv4 and IPv6 support. Configure transit gateway peering. Configure routing between the VPCs and the on-premises environment.
To meet the requirements of establishing connectivity between the existing VPC in us-east-1 and the new VPC in us-east-2, while also supporting IPv6 for the new VPC and enabling new on-premises resources to connect to VPC resources using IPv6 addresses, the solution must involve a transit gateway. Transit gateways allow for the interconnection of VPCs and on-premises networks across multiple regions, supporting both IPv4 and IPv6. Option B is the correct choice because it involves creating a transit gateway in both us-east-1 and us-east-2, attaching both VPCs to their respective transit gateways, creating new Site-to-Site VPN connections with IPv4 and IPv6 support, configuring transit gateway peering, and setting up routing between the VPCs and the on-premises environment. This approach ensures comprehensive connectivity and IPv6 support across the entire network architecture.

A company operates a single VPC in the us-east-1 Region and plans to create a new VPC in the us-east-2 Region. The existing VPC is connected to the company's on-premises environment via an AWS Site-to-Site VPN using a virtual private gateway. A network engineer must design a solution to enable connectivity between the existing VPC and the new VPC while ensuring IPv6 support for the new VPC. Additionally, the solution must allow new on-premises resources to connect to VPC resources using IPv6 addresses.
Which solution meets these requirements?
A
Create a new virtual private gateway in us-east-1. Attach the new virtual private gateway to the new VPC. Create two new Site-to-Site VPN connections to the new virtual private gateway with IPv4 and IPv6 support. Configure routing between the VPCs by using VPC peering.
B
Create a transit gateway in us-east-1 and in us-east-2. Attach the existing VPC and the new VPC to each transit gateway. Create a new Site-to-Site VPN connection to each transit gateway with IPv4 and IPv6 support. Configure transit gateway peering. Configure routing between the VPCs and the on-premises environment.
C
Create a new virtual private gateway in us-east-2. Attach the new virtual private gateway to the new VPCreate two new Site-to-Site VPN connections to the new virtual private gateway with IPv4 and IPv6 support. Configure routing between the VPCs by using VPC peering.
D
Create a transit gateway in us-east-1. Attach the existing VPC and the new VPC to the transit gateway. Create two new Site-to-Site VPN connections to the transit gateway with IPv4 and IPv6 support. Configure transit gateway peering. Configure routing between the VPCs and the on-premises environment.
