The scenario requires DNS queries originating from an on-premises network to be resolved for resources within an AWS VPC. Amazon Route 53 Resolver is the service designed for this hybrid cloud DNS integration. An inbound endpoint for Route 53 Resolver provides one or more elastic network interfaces (ENIs) within the VPC. The on-premises DNS server can then be configured to conditionally forward DNS queries for the VPC's domain to the IP addresses of these ENIs. The inbound endpoint allows Route 53 Resolver to receive these queries from the on-premises network over the Direct Connect connection and resolve them using the VPC's DNS.

A. AWS Verified Access is a service for providing secure, VPN-less access to corporate applications. It is not a general-purpose DNS resolution service for hybrid networks.

B. AWS Direct Connect provides the private network connectivity between the on-premises data center and the VPC, but it does not have built-in DNS resolution capabilities.

C. A Route 53 Resolver outbound endpoint is used for the opposite direction: forwarding DNS queries from the VPC to an on-premises DNS server.

1. Amazon Route 53 Developer Guide: Under the section "Resolving DNS queries between VPCs and your network

" it states

"To forward DNS queries from your network to Route 53 Resolver

you create a Route 53 Resolver inbound endpoint in a VPC... Then you configure your on-premises DNS resolver to forward the applicable DNS queries to the IP addresses for the inbound endpoint." (See: How Route 53 Resolver works with your network).

2. Amazon Route 53 Developer Guide: The guide clarifies the function of endpoints: "Inbound Resolver endpoints allow DNS queries to your VPC from your on-premises network or another VPC." (See: Managing Resolver endpoints).

3. AWS Documentation - What is AWS Verified Access?: This service is described as one that "provides secure access to your corporate applications without requiring a VPN." This confirms it is an application access service

not a DNS resolver. (See: AWS Verified Access User Guide

Introduction).

4. AWS Documentation - What is AWS Direct Connect?: This service is defined as a way "to establish a dedicated network connection from your premises to AWS." It is a networking service

not a DNS service. (See: AWS Direct Connect User Guide

Introduction).
