Question

A company uses a hybrid architecture and has an AWS Direct Connect connection between its on-premises data center and AWS. The company has production applications that run in the on- premises data center. The company also has production applications that run in a VPC. The applications that run in the on-premises data center need to communicate with the applications that run in the VPC. The company is using corp.example.com as the domain name for the on- premises resources and is using an Amazon Route 53 private hosted zone for aws.example.com to host the VPC resources. The company is using an open-source recursive DNS resolver in a VPC subnet and is using a DNS resolver in the on-premises data center. The company's on- premises DNS resolver has a forwarder that directs requests for the aws.example.com domain name to the DNS resolver in the VPC. The DNS resolver in the VPC has a forwarder that directs requests for the corp.example.com domain name to the DNS resolver in the on-premises data center. The company has deckled to replace the open-source recursive DNS resolver with Amazon Route 53 Resolver endpoints. Which combination of steps should a network engineer take to make this replacement? (Choose three.)

Options

  • ACreate a Route 53 Resolver rule to forward aws.example.com domain queries to the IP
  • BConfigure the on-premises DNS resolver to forward aws.example.com domain queries to the IP
  • CCreate a Route 53 Resolver inbound endpoint and a Route 53 Resolver outbound endpoint.
  • DCreate a Route 53 Resolver rule to forward aws.example.com domain queries to the IP
  • ECreate a Route 53 Resolver rule to forward corp.example.com domain queries to the IP address
  • FConfigure the on-premises DNS resolver to forward aws.example.com queries to the IP
