Topic 1 Question 363
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?
Set up an Amazon Route 53 inbound resolver endpoint with a forwarding rule for the onprem.private hosted zone. Associate the resolver with the VPC of the EC2 instance. Configure the on-premises DNS resolver to forward onprem.private DNS queries to the inbound resolver endpoint.
Set up an Amazon Route 53 inbound resolver endpoint. Associate the resolver with the VPC of the EC2 instance. Configure the on-premises DNS resolver to forward awscloud.private DNS queries to the inbound resolver endpoint.
Set up an Amazon Route 53 outbound resolver endpoint with a forwarding rule for the onprem.private hosted zone. Associate the resolver with the AWS Region of the EC2 instance. Configure the on-premises DNS resolver to forward onprem.private DNS queries to the outbound resolver endpoint.

A: By setting up an inbound resolver endpoint in Amazon Route 53 and associating it with the VPC of the EC2 instance, DNS queries for the onprem.private hosted zone originating from the on-premises network will be resolved by the Amazon Route 53 resolver. The inbound resolver endpoint acts as a DNS forwarder, forwarding DNS queries to the on-premises DNS resolver.
👍 3Pete9872023/06/30 Option A involves setting up an Amazon Route 53 inbound resolver endpoint with a forwarding rule for the onprem.private hosted zone, associating the resolver with the VPC of the EC2 instance, and configuring the on-premises DNS resolver to forward onprem.private DNS queries to the inbound resolver endpoint. However, this solution would not allow the on-premises application to resolve the EC2 instance hostname because it is forwarding queries for the onprem.private hosted zone instead of the awscloud.private hosted zone.
Option B is still the correct solution as it involves setting up an Amazon Route 53 inbound resolver endpoint, associating the resolver with the VPC of the EC2 instance, and configuring the on-premises DNS resolver to forward awscloud.private DNS queries to the inbound resolver endpoint. This would allow the on-premises application to resolve the EC2 instance hostname.
B is correct.
