Exam AWS Certified SysOps Administrator - Associate topic 1 question 421 discussion

Exam question from Amazon's AWS Certified SysOps Administrator - Associate
Question #: 421
Topic #: 1
[All AWS Certified SysOps Administrator - Associate Questions]

A company manages its production applications across several AWS accounts. The company hosts the production applications on Amazon EC2 instances that run Amazon Linux 2. The EC2 instances are spread across multiple VPCs. Each VPC uses its own Amazon Route 53 private hosted zone for private DNS.

A VPC from Account A needs to resolve private DNS records from a private hosted zone that is associated with a different VPC in Account B.

What should a SysOps administrator do to meet these requirements?

  • A. In Account A, create an AWS Systems Manager document that updates the /etc/resolv.conf file across all EC2 instances to point to the AWS provided default DNS resolver for the VPC in Account B.
  • B. In Account A, create an AWS CloudFormation template that associates the private hosted zone from Account B with the private hosted zone in Account A.
  • C. In Account A, use the AWS CLI to create a VPC association authorization. When the association is created, use the AWS CLI in Account B to associate the VPC from Account A with the private hosted zone in Account B.
  • D. In Account B, use the AWS CLI to create a VPC association authorization. When the association is created, use the AWS CLI in Account A to associate the VPC from Account B with the private hosted zone in Account A.

Selected Answer: D
I think it's D, because C is the wrong way around. C allows for resources in account B to resolve resources in account A. The question asks for the other way, from account A to account B.
