To simplify the configuration, the
db.example.com CNAME record set for the Amazon RDS endpoint was created in a private hosted zone for
Amazon Route 53.
During deployment, the application failed to start. Troubleshooting revealed that db.example.com is not
resolvable on the Amazon EC2 instance. The solutions architect confirmed that the record set was created
correctly in Route 53.
Which combination of steps should the solutions architect take to resolve this issue? (Select 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
