A company is using a VPC peering strategy to connect its VPCs in a single Region to allow for cross-communication. A recent increase in account creations andVPCs has made it difficult to maintain the VPC peering strategy, and the company expects to grow to hundreds of VPCs. There are also new requests to create site-to-site VPNs with some of the VPCs. A solutions architect has been tasked with creating a centrally managed networking setup for multiple accounts, VPCs, and VPNs.
Which networking solution meets these requirements?

A. Configure shared VPCs and VPNs and share to each other. B. Configure a hub-and-spoke VPC and route all traffic through VPC peering. C. Configure an AWS Direct Connect connection between all VPCs and VPNs. D. Configure a transit gateway with AWS Transit Gateway and connect all VPCs and VPNs.
