A company has established hybrid connectivity between its VPCs and on-premises data center, with the on-premises.example.com subdomain configured on its on-premises DNS server and the aws.example.com subdomain used for AWS workloads across multiple VPCs and accounts. Resources in both environments can communicate via IP addresses. The company aims to enable workloads in the VPCs to access on-premises resources using the on-premises.example.com DNS names with the LEAST amount of resource management. What solution meets these requirements?
A
Create an Amazon Route 53 Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.
B
Create an Amazon Route 53 Resolver inbound endpoint and a Resolver outbound endpoint. Configure a Resolver rule that conditionally forwards DNS queries for on-premises.example.com to the on-premises DNS server. Associate the rule with the VPCs.
C
Launch an Amazon EC2 instance. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.
D
Launch an Amazon EC2 instance in each VPC. Install and configure BIND software to conditionally forward DNS queries for on-premises.example.com to the on-premises DNS server. Configure the EC2 instance's IP address as a custom DNS server in each VPC.
