Topic 1 Question 322
A company is migrating mobile banking applications to run on Amazon EC2 instances in a VPC. Backend service applications run in an on-premises data center. The data center has an AWS Direct Connect connection into AWS. The applications that run in the VPC need to resolve DNS requests to an on-premises Active Directory domain that runs in the data center.

Which solution will meet these requirements with the LEAST administrative overhead?
- Provision a set of EC2 instances across two Availability Zones in the VPC as caching DNS servers to resolve DNS queries from the application servers within the VPC.
- Provision an Amazon Route 53 private hosted zone. Configure NS records that point to on-premises DNS servers.
- Create DNS endpoints by using Amazon Route 53 Resolver. Add conditional forwarding rules to resolve DNS namespaces between the on-premises data center and the VPC.
- Provision a new Active Directory domain controller in the VPC with a bidirectional trust between this new domain and the on-premises Active Directory domain.

  To forward DNS queries from your VPCs to your network, you create an outbound endpoint. reference: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver-forwarding-outbound-queries.html
