Deployment, Provisioning, and Automation
A company is trying to connect two applications. One application runs in an on-premises data center that has a hostname of host1.onprem.private. The other application runs on an Amazon EC2 instance that has a hostname of host1.awscloud.private. An AWS Site-to-Site VPN connection is in place between the on-premises network and AWS.
The application that runs in the data center tries to connect to the application that runs on the EC2 instance, but DNS resolution fails. A SysOps administrator must implement DNS resolution between on-premises and AWS resources.
Which solution allows the on-premises application to resolve the EC2 instance hostname?
