Selected Answer: B

If the VPCs are in the same AZ, and that is the case here, there will be no cost for traffic like if it goes via VPN through the internet. B is definitly the right answer here ..

Selected Answer: B

B: VPC peering is a networking connection between two VPCs that enables you to route traffic between them using private IPv4 addresses or IPv6 addresses. It's a low-cost solution for interconnecting two VPCs, especially when they're located in the same AWS region.

Since the non-production systems and the primary node of the production systems are in the same Availability Zone, establishing a VPC peering connection is a straightforward and cost-effective solution. It does not incur any additional data transfer costs within the same AWS Region, making it an efficient choice. Option A (AWS Transit Gateway) is a scalable and centralized solution, but it may introduce additional complexity and cost for this scenario, which involves only two VPCs. Option C (AWS Site-to-Site VPN) is typically used for secure connections between on-premises networks and AWS, and may not be necessary in this case where both VPCs are within AWS. Option D (AWS Direct Connect) is a dedicated network connection and may be overkill for connecting two VPCs within the same Availability Zone.
