A company runs BIND-based custom DNS servers in a central VPC to provide name resolution for VPCs across multiple AWS accounts in the same AWS Organization. All VPCs are attached to a transit gateway. The central BIND servers forward queries for an on-premises DNS domain to DNS servers in the on-premises data center. Each VPC has a DHCP options set that points to the custom DNS servers so all VPCs use them. Multiple development teams need to use Amazon EFS. One team created a new EFS file system but an EC2 instance cannot mount it because the instance cannot resolve fs-33444567d.efs.us-east-1.amazonaws.com. What combination of actions will allow development teams across the organization to mount EFS file systems? (Choose two.)

The correct options enable EFS resolution and maintain on-premises connectivity. Updating DHCP options sets to use AmazonProvidedDNS (169.254.169.253) allows VPCs to resolve AWS service endpoints like EFS. To continue resolving on-premises domains, a Route 53 Resolver outbound endpoint is needed in the central VPC, along with a Resolver rule that forwards on-premises queries to the on-premises DNS servers. Sharing this rule via AWS RAM and associating it with all VPCs ensures consistent on-premises resolution across the organization. Configuring BIND to forward efs.us-east-1.amazonaws.com to 169.254.169.253 is incorrect because 169.254.169.253 is the IP for the Amazon-provided DNS resolver, not a specific EFS endpoint. An inbound endpoint is for on-premises to AWS resolution, not AWS to AWS or AWS to on-premises. A private hosted zone for efs.us-east-1.amazonaws.com is not the standard or scalable solution for EFS resolution and would require manual updates for each EFS file system.
