Topic 1 Question 119
A network engineer is working on a private DNS design to integrate AWS workloads and on-premises resources. The AWS deployment consists of five VPCs in the eu-west-1 Region that connect to the on-premises network over AWS Direct Connect. The VPCs communicate with each other by using a transit gateway. Each VPC is associated with a private hosted zone that uses the aws.example.internal domain. The network engineer creates an Amazon Route 53 Resolver outbound endpoint in a shared services VPC and attaches the shared services VPC to the transit gateway.
The network engineer is implementing a solution for DNS resolution. Queries for hostnames that end with aws.example.internal must use the private hosted zone. Queries for hostnames that end with all other domains must be forwarded to a private on-premises DNS resolver.
Which solution will meet these requirements?
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.
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.
Add a forwarding rule for “*” that targets the Route 53 Resolver outbound endpoint.
Add a forwarding rule for “.” that targets the Route 53 Resolver outbound endpoint.

👍 1demoras2023/06/08 In AWS Route 53, to reach public domains and on-premises networks, you would typically use a forwarding rule.
A forwarding rule allows you to forward DNS queries for a specific domain or subdomain to another DNS resolver. This is useful when you want to forward DNS queries from your Route 53 Resolver to an on-premises DNS server or to another DNS service provider for resolution.
On the other hand, a system rule is used to specify how the Route 53 Resolver handles DNS queries that don't match any forwarding rules or DNS rules that you've configured. It is typically used for fallback or default behavior.
So, to reach public domains and on-premises networks, you would configure a forwarding rule in Route 53 to forward the DNS queries to the appropriate DNS resolver for resolution.
answer is A
