Topic 1 Question 258
A company's VPC has connectivity to an on-premises data center through an AWS Site-to-Site VPN. The company needs Amazon EC2 instances in the VPC to send DNS queries for example.com to the DNS servers in the data center.
Which solution will meet these requirements?
Create an Amazon Route 53 Resolver inbound endpoint. Create a conditional forwarding rule on the on-premises DNS servers to forward DNS requests for example.com to the inbound endpoints.
Create an Amazon Route 53 Resolver inbound endpoint. Create a forwarding rule on the resolver that sends all queries for example.com to the on-premises DNS servers. Associate this rule with the VPC.
Create an Amazon Route 53 Resolver outbound endpoint. Create a conditional forwarding rule on the on-premises DNS servers to forward DNS requests for example.com to the outbound endpoints.
Create an Amazon Route 53 Resolver outbound endpoint. Create a forwarding rule on the resolver that sends all queries for example.com to the on-premises DNS servers. Associate this rule with the VPC.

D - since we want to forward DNS queries to an on-prem DNS server, we need to create a Route53 outbound resolver endpoint. The last step of the configuration process it to associate the rule with a VPC (not necessarily the same where we created the outbound endpoint).

An inbound endpoint in Amazon Route 53 Resolver receives DNS queries from resources in your VPC and forwards them to the DNS resolvers that are defined in the inbound endpoint. This is the reason why an inbound endpoint with a forwarding rule should be created to allow EC2 instances in the VPC to send DNS queries for example.com to the DNS servers in the on-premises data center.
