Show Suggested Answer Hide Answer
Suggested Answer: B

Establish a VPC peering connection between the two VPCs Add the appropriate routes in the subnet route tables is the most cost-effective way to establish a connection between the production systems and the non-production systems. VPC Peering allows for direct and private communication between VPCs and does not require any additional components such as internet gateways or VPN connections. This method is more cost-effective than using a Transit Gateway or Direct Connect and also provides better security as the traffic remains within the AWS network.

I think the Transit Gateway is more scalable though.

VPC peering is usually cheaper than a Transit Gateway.

Direct Connect seems too expensive for this case, right? I feel like the VPN option could work, but I’m not sure about the costs involved.

I practiced a similar question about connecting VPCs, and I think VPC peering was the answer, but I’m not completely confident.

I think using a Transit Gateway could be more scalable, but I need to double-check if it's the cheapest solution for this scenario.

I remember studying VPC peering, but I'm not sure if it's the most cost-effective option here.
