QuestionQ19
Design Solutions for Organizational ComplexityA company uses multiple AWS accounts. DNS records are kept in an Amazon Route 53 private hosted zone in Account A, while the company's applications and databases run in Account B.
A solutions architect will deploy a two-tier application into a new VPC. To simplify configuration, a db.example.com CNAME record set for the Amazon RDS endpoint was created in an Amazon Route 53 private hosted zone.
During deployment, the application did not start. Troubleshooting showed that db.example.com cannot be resolved from the Amazon EC2 instance. The solutions architect verified that the record set was correctly created in Route 53.
Which combination of steps should the solutions architect take to resolve this issue?
Choose two
- A Deploy the database on a separate EC2 instance in the new VPC. Create a record set for the instance’s private IP in the private hosted zone.
- B Use SSH to connect to the application tier EC2 instance. Add an RDS endpoint IP address to the /etc/resolv.conf file.
- C Create an authorization to associate the private hosted zone in Account A with the new VPC in Account B.
- D Create a private hosted zone for the example com domain in Account B. Configure Route 53 replication between AWS accounts.
- E Associate a new VPC in Account B with a hosted zone in Account A. Delete the association authorization in Account A.
