Question

A company hosts its website on Amazon EC2 instances in the us-east-1 Region. The company is preparing to extend its website into the eu-central-1 Region, but the database must remain only in us-east-1. After deployment, the EC2 instances in eu-central-1 are unable to connect to the database in us-east-1. What is the MOST operationally efficient solution that will resolve this connectivity issue?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create a VPC peering connection between the two Regions. Add the private IP address range of the instances to the inbound rule of the database security group. VPC peering privately connects two VPCs without a gateway.
