Answer: Implement a transit gateway and attach all company VPCs and subnets to it., Deploy a Network Load Balancer (NLB) targeting the license validation compute resource. Set up an AWS PrivateLink endpoint service accessible to each customer VPC and link it with the NLB.
The combination of A and C provides the required VPC connectivity with the least operational overhead. Option A suggests using a transit gateway, which is a scalable solution for connecting multiple VPCs efficiently. Option C involves creating a Network Load Balancer and an AWS PrivateLink endpoint service, allowing secure and scalable access to the license validation compute resource from customer VPCs. These methods avoid the complexity and limitations of VPC peering (option B) and the overhead of VPN appliances (option D), while VPC peering for all connections (option E) would not scale well with the growing number of VPCs.

A SaaS company offers a media software solution across 50 VPCs in various AWS Regions and accounts, with one designated as a management VPC. Compute resources operate independently. A new feature necessitates inter-VPC communication and one-way access from customer VPCs to the management VPC for license validation. As the solution expands, more VPCs will be added. What combination of steps provides the required VPC connectivity with minimal operational overhead? (Select two.)
A
Implement a transit gateway and attach all company VPCs and subnets to it.
B
Establish VPC peering connections among all company VPCs.
C
Deploy a Network Load Balancer (NLB) targeting the license validation compute resource. Set up an AWS PrivateLink endpoint service accessible to each customer VPC and link it with the NLB.
D
Install a VPN appliance in each customer VPC and connect them to the management VPC using AWS Site-to-Site VPN.
E
Set up a VPC peering connection between the management VPC and each customer VPC.
