A small company has several AWS accounts that are used by multiple teams. To centralize DNS record keeping, the company has created a private hosted zone in Amazon Route 53 on the main Account A. The new application and database servers are hosted on a VPC in Account B. The CNAME record set db.turotialsdojo.com has been created for the Amazon RDS endpoint on the private hosted zone in Amazon Route 53. Upon deployment, the application on the Amazon EC2 instances failed to start. The application logs indicate that the database endpoint db.turotialsdojo.com is not resolvable. However, the solutions architect can confirm that the Route 53 entry is configured correctly.

Which of the following options is the recommended solution for this issue? (Select TWO.)

On Account B, associate the VPC to the private hosted zone in Account A. Delete the association authorization after the association is created.
On Account A, create an authorization to associate its private hosted zone to the new VPC in Account B.
Create a VPC peering between the Account A VPC and Account B VPC. Configure the Amazon EC2 instances on Account B to use the DNS resolver IPs in Account A to resolve the Amazon RDS endpoint.
On Account B, create a new private hosted zone in Amazon Route 53. Associate this zone to the private hosted zone in Account A to allow replication between the AWS accounts.
Create custom AMI for the Amazon EC2 instances that have an updated /etc/resolv.conf file containing the Amazon RDS endpoint to private IP address mapping.

route 53의 private hosted zone을 다른 계정와 공유하는 방법을 아는가? 라는 문제

A hosted zone is a container for records, and records contain information about how you want to route traffic for a specific domain, such as example.com, and its subdomains (acme.example.com, zenith.example.com). A hosted zone and the corresponding domain have the same name. There are two types of hosted zones:

Public hosted zones contain records that specify how you want to route traffic on the internet. For more information, see Working with public hosted zones.
Private hosted zones contain records that specify how you want to route traffic in an Amazon VPC.
