Question 6

A global company operates all its non-production environments out of three AWS Regions: eu-west-1, us-east-1, and us-west-1. The company hosts all its production workloads in two on-premises data centers. The company has 60 AWS accounts and each account has two VPCs in each Region. Each VPC has a virtual private gateway where two VPN connections terminate for resilient connectivity to the data centers. The company has 360 VPN tunnels to each data center, resulting in high management overhead. The total VPN throughput for each Region is 500 Mbps.
The company wants to migrate the production environments to AWS. The company needs a solution that will simplify the network architecture and allow for future growth. The production environments will generate an additional 2 Gbps of traffic per Region back to the data centers. This traffic will increase over time. Which solution will meet these requirements?  

A. Set up an AWS Direct Connect connection from each data center to AWS in each Region. Create and attach private VIFs to a single Direct Connect gateway. Attach the Direct Connect gateway to all the VPCs. Remove the existing VPN connections that are attached directly to the virtual private gateways. 
B. Create a single transit gateway with VPN connections from each data center. Share the transit gateway with each account by using AWS Resource Access Manager (AWS RAM). Attach the transit gateway to each VPC. Remove the existing VPN connections that are attached directly to the virtual private gateways. 
C. Create a transit gateway in each Region with multiple newly commissioned VPN connections from each data center. Share the transit gateways with each account by using AWS Resource Access Manager (AWS RAM). In each Region, attach the transit gateway to each VPRemove the existing VPN connections that are attached directly to the virtual private gateways.
D. Peer all the VPCs in each Region to a new VPC in each Region that will function as a centralized transit VPC. Create new VPN connections from each data center to the transit VPCs. Terminate the original VPN connections that are attached to all the original VPCs. Retain the new VPN connection to the new transit VPC in each Region.
