  • Topic 1 Question 289

    A company has a hybrid environment. The company has set up an AWS Direct Connect connection between the company's on-premises data center and a workload that runs in a VPC. The company uses Amazon Route 53 for DNS on AWS. The company uses a private hosted zone to manage DNS names for a set of services that are hosted on AWS.

    The company wants the on-premises servers to use Route 53 for DNS resolution of the private hosted zone.

    Which solution will meet these requirements?

    • Create a Route 53 inbound endpoint. Ensure that security groups and routing allow the traffic from the on-premises data center. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone's domain name to the IP addresses of the inbound endpoint.

    • Create a Route 53 outbound endpoint. Ensure that security groups and routing allow the traffic from the VPC. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the IP addresses of the outbound endpoint.

    • Edit the private hosted zone in Route 53 with a TXT record that references the on-premises DNS servers. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the base of the VPC CIDR IPv4 network range, plus two.

    • Edit the private hosted zone in Route 53 with a PTR record that references the on-premises DNS servers. Configure the DNS server on the on-premises network to conditionally forward DNS queries for the private hosted zone’s domain name to the base of the VPC CIDR IPv4 network range, plus two.
