An enterprise is designing a hybrid DNS resolution strategy. They have an on-premises data center connected to AWS via Direct Connect. They need on-premises servers to resolve DNS names of AWS resources (like RDS endpoints), and AWS EC2 instances to resolve on-premises hostnames. Which THREE components are required to build this architecture? (Select THREE)

Answer options:

Amazon Route 53 Resolver Inbound Endpoint

Amazon Route 53 Resolver Outbound Endpoint

Route 53 Resolver Rules forwarding on-premises domains to the Outbound Endpoint

AWS Transit Gateway

Amazon API Gateway

Route 53 Public Hosted Zone

How to approach this question

Identify the three components of Route 53 Resolver for hybrid DNS (Inbound, Outbound, and Rules).

Full Answer

To establish hybrid DNS, you need an Inbound Endpoint (so on-prem can query AWS), an Outbound Endpoint (so AWS can query on-prem), and Resolver Rules attached to the VPC to tell AWS which specific domain names should be forwarded to the Outbound Endpoint.

Common mistakes

Confusing network routing (Transit Gateway) with DNS resolution.
