You’ve set up a private hosted zone in Route 53. You’ve set up a VPN connection between the AWS VPC and your on-premises network. You need to ensure that you can resolve DNS names from on-premises to the resources records defined in the Private hosted zone. How can you accomplish this?

Answer options:

A.Create a DNS resolver server in your on-premises location. Configure the VPC with a new DHCP option set which uses this DNS resolver.
B.Create a DNS forwarder server in your on-premises location. Configure the VPC with a new DHCP option set which uses this DNS forwarder.
C.Configure a DNS forwarder on-premises, which will forward DNS requests to a Route53 Resolver Inbound Endpoint.
D.Configure a DNS resolver in the VPC to resolve DNS requests to the Route 53 private hosted zone.

Answer – C
Options A and D are incorrect since you need to use a DNS forwarder.
Option B is incorrect since the forwarder needs to be defined in the VPC.Such an example is also given in the AWS Documentation.
Issue
How can I resolve Amazon Route 53 private hosted zones from an on-premises network via an Ubuntu instance?
Resolution
You can resolve domain names in private hosted zones from your on-premises network by configuring a DNS forwarder. The following instructions assume that your on-premises network is configured with a VPN or AWS Direct Connect to an AWS VPC, and a Route 53 private hosted zone is associated with that VPC.For full details on this configuration, please refer to the below URL
