To enable DNS resolution for an interface endpoint from on-premises and multiple VPCs in a hybrid, hub-and-spoke model, a specific configuration is required. First, the interface endpoint for Amazon SQS must be created with the "Enable private DNS name" option turned on. This automatically creates a private hosted zone (e.g., sqs.us-east-1.amazonaws.com) with records pointing to the endpoint's private IPs. Second, this automatically created private hosted zone, which is initially associated only with the VPC where the endpoint was created, must be manually associated with the other spoke VPCs and the central hub VPC. This allows Route 53 Resolver to resolve queries from those VPCs and from on-premises (via the inbound endpoint in the hub VPC). Finally, applications will use the standard public service DNS name to access the service, which will now resolve privately.

B. Disabling private DNS names would require clients to use the long, endpoint-specific DNS name, which is not the standard practice for seamless integration.

C. Manually creating the private hosted zone is unnecessary and error-prone, as enabling the private DNS option on the endpoint handles this automatically.

F. Using the endpoint-specific DNS name is a valid but less desirable method; the primary benefit of enabling private DNS is to use the standard service name transparently.

1. AWS Documentation, VPC User Guide, "Interface VPC endpoints (AWS PrivateLink)": Under the "Private DNS" section, it states, "If you enable private DNS for your interface endpoint, you can make requests to the service using its default DNS hostname for the Region... AWS creates a private hosted zone and associates it with your VPC." This supports option A and the use of the standard service name in option E.

2. AWS Documentation, Route 53 Developer Guide, "Working with private hosted zones": The section "Associating a VPC with a private hosted zone" explains the procedure for sharing a private hosted zone across multiple VPCs. This is the mechanism required by option D to allow resolution from other VPCs and the hub VPC where the Resolver endpoint resides.

3. AWS Documentation, Route 53 Developer Guide, "Resolving DNS queries between VPCs and your network": This guide details how Route 53 Resolver inbound endpoints resolve queries from an on-premises network. It clarifies that the inbound endpoint can resolve records in private hosted zones associated with its VPC. This confirms that the SQS private hosted zone must be associated with the hub VPC (as per option D) for on-premises resolution to work.
