AWS Certified Advanced Networking - Specialty ANS-C01 — Question 287

A company has a hybrid environment. The company uses AWS Direct Connect with a transit VIF attached to a transit gateway to connect its on-premises location to the AWS Cloud. The company operates from a single AWS account in the us-east-1 Region. The company has a legacy application that runs on premises with the corp.example.com DNS name. The company has created an Amazon Route 53 Resolver outbound endpoint and a Resolver rule in us-east-1 in the AWS account. As part of an expansion, the company creates one more AWS account for a new business unit that operates in us-east-1. The new account has VPCs that are attached to the transit gateway. The new account uses the existing Direct Connect connection to connect to the on-premises location. Applications that run in the new account's VPCs also need to access the on-premises location by using the corp.example.com DNS name. A network engineer needs to identify a solution to resolve the corp.example.com DNS name from the new account. Which solution will meet these requirements MOST cost-effectively?
