A Company Has a Hybrid Environment Across Its On-Premises Network

question 338

Multiple Choice

A company has a hybrid environment across its on-premises network and the AWS Cloud. The company wants to use Amazon Elastic File System (Amazon EFS) to store and share data between on-premises services that are required to resolve DNS queries through on-premises DNS servers. The company wants to use a custom domain name to connect to Amazon EFS. The company also wants to avoid using the Amazon EFS target IP address. What should a network engineer do to meet these requirements?

• A) Create an Amazon Route 53 Resolver outbound endpoint, and configure it for the VPC where Amazon EFS resides. Create a Route 53 public hosted zone, and add a new CNAME record with the value of the Amazon EFS DNS name. Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 public hosted zone.
• B) Create an Amazon Route 53 Resolver inbound endpoint, and configure it for the VPC where Amazon EFS resides. Create a Route 53 private hosted zone, and add a new CNAME record with the value of the Amazon EFS DNS name. Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 Resolver.
• C) Create an Amazon Route 53 Resolver outbound endpoint, and configure it for the VPC where Amazon EFS resides. Create a Route 53 private hosted zone, and add a new CNAME record with the value of the Amazon EFS DNS name. Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 Resolver.
• D) Create an Amazon Route 53 Resolver inbound endpoint, and configure it for the VPC where Amazon EFS resides. Create a Route 53 private hosted zone, and add a new PTR record with the value of the Amazon EFS DNS name. Configure forwarding rules on the on-premises DNS servers to forward queries for the custom domain host to the Route 53 private hosted zone.
