A network engineer is designing a private DNS solution to integrate AWS workloads and on-premises resources. The AWS environment includes five VPCs in the eu-west-1 Region, connected to the on-premises network via AWS Direct Connect. The VPCs communicate with each other through a transit gateway, and each VPC is associated with a private hosted zone using the aws.example.internal domain. The engineer has created an Amazon Route 53 Resolver outbound endpoint in a shared services VPC, which is attached to the transit gateway.
The engineer needs to implement a DNS resolution solution where queries for hostnames ending with aws.example.internal are resolved using the private hosted zone, and queries for hostnames ending with all other domains are forwarded to a private on-premises DNS resolver.
Which solution meets these requirements?
A
Add a forwarding rule for “” that targets the on-premises server's DNS IP address. Add a system rule for aws.example.internal that targets Route 53 Resolver.
B
Add a forwarding rule for aws.example.internal that targets Route 53 Resolver. Add a system rule for “.” that targets the Route 53 Resolver outbound endpoint.
C
Add a forwarding rule for “” that targets the Route 53 Resolver outbound endpoint.
D
Add a forwarding rule for “.” that targets the Route 53 Resolver outbound endpoint.
