Answer: Configure a transit gateway. Attach each VPC to the transit gateway. Configure static routing in each VPC to route traffic to the transit gateway.
To achieve the highest throughput for connectivity between the three VPCs, the best solution is to use a transit gateway. A transit gateway acts as a hub that controls how traffic is routed among all connected networks which in this case are the three VPCs. This setup allows for high bandwidth and low latency communication between the VPCs. Option A suggests configuring a transit gateway and attaching each VPC to it, then configuring static routing in each VPC to route traffic to the transit gateway. This approach is scalable and provides the highest throughput among the options given. Option B, configuring VPC peering, does not support transitive routing, meaning each VPC would need to be peered with every other VPC, leading to a complex and less scalable solution. Option C, configuring a VPN gateway and creating AWS Site-to-Site VPN tunnels, introduces additional latency and does not provide as high throughput as a transit gateway. Option D, configuring AWS Site-to-Site VPN connections between each VPC, also introduces latency and does not offer the same level of throughput as a transit gateway. Therefore, the correct answer is A.

A company has three VPCs in the same AWS Region, each containing 15 Amazon EC2 instances, with no current connectivity between them. A new application requiring high bandwidth between nodes is being deployed across all three VPCs.
What solution should a network engineer implement to provide the HIGHEST throughput for connectivity between the VPCs?
A
Configure a transit gateway. Attach each VPC to the transit gateway. Configure static routing in each VPC to route traffic to the transit gateway.
B
Configure VPC peering between the three VPCs. Configure static routing to route traffic between the three VPCs.
C
Configure a transit VPConfigure a VPN gateway in each VPCreate an AWS Site-to-Site VPN tunnel from each VPC to the transit VPUse BGP routing to route traffic between the VPCs and the transit VPC.
D
Configure AWS Site-to-Site VPN connections between each VPC. Enable route propagation for each Site-to-Site VPN connection to route traffic between the VPCs.
