Question

Example Corp. has an on-premises data center and a VPC named VPC A in the Example Corp. AWS account. The on-premises network connects to VPC A through an AWS Site-To-Site VPN. The on-premises servers can properly access VPC A. Example Corp. just acquired AnyCompany, which has a VPC named VPC B. There is no IP address overlap among these networks. Example Corp. has peered VPC A and VPC B. Example Corp. wants to connect from its on-premise servers to VPC B. Example Corp. has properly set up the network ACL and security groups. Which solution will meet this requirement with the LEAST operational effort?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create a transit gateway. Attach the Site-to-Site VPN, VPC A, and VPC B to the transit gateway. Update the transit gateway route tables for all networks to add IP range routes for all other networks. AWS Transit Gateway centrally connects many VPCs and on-premises networks at scale. AWS Site-to-Site VPN provides encrypted connectivity between on premises and a VPC.
