A company’s processing team has an AWS account with a production application. The application runs on Amazon EC2 instances behind a Network Load Balancer (NLB). The EC2 instances are hosted in private subnets in a VPC in the eu- west- 1 Region. The VPC was assigned the CIDR block of 10.0.0.0/16. The billing team recently created a new AWS account and deployed an application on EC2 instances that are hosted in private subnets in a VPC in the eu-central-1 Region. The new VPC is assigned the CIDR block of 10.0.0.0/16.

The processing application needs to securely communicate with the billing application over a proprietary TCP port. What should a solutions architect do to meet this requirement with the LEAST amount of operational effort?

A.
In the billing team’s account, create a new VPC and subnets in eu-central-1 that use the CIDR block of 192.168.0.0/16. Redeploy the application to the new subnets. Configure a VPC peering connection between the two VPCs.

B.
In the processing team’s account, add an additional CIDR block of 192.168.0.0/16 to the VPC in eu-west-1. Restart each of the EC2 instances so that they obtain a new IP address. Configure an interRegion VPC peering connection between the two VPCs.
