Question

A company is migrating an application from on premises to AWS. The company will host the application on Amazon EC2 instances that are deployed in a single VPC. During the migration period, DNS queries from the EC2 instances must be able to resolve names of on-premises servers. The migration is expected to take 3 months After the 3-month migration period, the resolution of on-premises servers will no longer be needed. What should a network engineer do to meet these requirements with the LEAST amount of configuration?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Set up an AWS Site-to-Site VPN connection between on premises and AWS. Deploy an Amazon Route 53 Resolver outbound endpoint in the Region that is hosting the VPC. Amazon Route 53 provides DNS with health checks and routing policies for availability and latency. AWS Site-to-Site VPN provides encrypted connectivity between on premises and a VPC.
