A company plans to deploy a new private intranet service on Amazon EC2 instances inside a VPC. An AWS Site-to-Site VPN connects the VPC to the company’s on-premises network. The new service must communicate with existing onpremises services. The on-premises services are accessible through the use of hostnames that reside in the company.example DNS zone. This DNS zone is wholly hosted on premises and is available only on the company’s private network.

A solutions architect must ensure that the new service can resolve hostnames on the company example domain to integrate with existing services. Which solution meets these requirements?

A.
