Question

A company has several application accounts that include dual-stack VPCs. The company wants to implement a centralized DNS solution that supports IPv6. A network engineer deploys a shared services VPC. The network engineer sets up network connectivity between the company's application VPCs, the shared services VPC, and the company's on-premises environment with support for IPv4 and IPv6 traffic. The network engineer is using Amazon Route 53 to implement a centralized DNS solution. The network engineer needs to ensure that resources in the application VPCs have the ability to perform DNS queries against an on-premises DNS resolver. Which solution will meet this requirement?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create a Route 53 Resolver outbound endpoint in the shared services VPC within a dual-stack subnet. Use AWS Resource Access Manager (AWS RAM) to share the resolver rules to the application accounts. Amazon Route 53 provides DNS with health checks and routing policies for availability and latency.
