Question 701 · 1017 in bank
A company is designing a web application on AWS. The application will use a VPN connection between the company’s existing data centers and the company's VPCs. The company uses Amazon Route 53 as its DNS service. The application must use private DNS records to communicate with the on-premises services from a VPC. Which solution will meet these requirements in the MOST secure manner?
Show answer
Answer: A
Explanation
If you have workloads that leverage both VPCs and on-premises resources, you also need to resolve DNS records hosted on-premises. Similarly, these on-premises resources may need to resolve names hosted on AWS. Through Resolver endpoints and conditional forwarding rules, you can resolve DNS queries between your on-premises resources and VPCs to create a hybrid cloud setup over VPN or Direct Connect (DX). Specifically: Inbound Resolver endpoints allow DNS queries to your VPC from your on-premises network or another VPC. Outbound Resolver endpoints allow DNS queries from your VPC to your on-premises network or another VPC. Reference: https://docs.aws.amazon.com/Route53/latest/DeveloperGuide/resolver.html
