ANS-C01 Network Implementation Practice Question
A company wants to enable DNS resolution for hybrid network using Route 53 Resolver. The on-premises DNS servers are reachable via Direct Connect. The company wants to forward queries for a custom domain (example.corp) from VPC to on-premises. Which resource should be created in the VPC?
⚠ Common exam trap
The ANS-C01 exam often tests the distinction between inbound and outbound endpoints; the trap here is confusing the direction of DNS traffic, leading candidates to select the inbound endpoint (Option C) when outbound forwarding is required.

Correct answer & explanation
✓
Route 53 Resolver outbound endpoint and associate a resolver rule.
To forward DNS queries from a VPC to on-premises DNS servers, you need a Route 53 Resolver outbound endpoint, which initiates outbound DNS traffic from the VPC. You then associate a resolver rule that specifies the domain (example.corp) and the target on-premises DNS server IPs, enabling conditional forwarding via Direct Connect.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
A VPC endpoint for Route 53 Resolver service.
Why it's wrong here
A VPC endpoint is for accessing AWS services privately, not for DNS forwarding.
- ✗
Route 53 Resolver rule that forwards example.corp to on-premises DNS servers.
Why it's wrong here
A resolver rule must be associated with an outbound endpoint to forward queries.
- ✗
Route 53 Resolver inbound endpoint.
Why it's wrong here
An inbound endpoint allows on-premises DNS to forward queries to VPC, not the other way.
- ✓
Route 53 Resolver outbound endpoint and associate a resolver rule.
Why this is correct
An outbound endpoint forwards DNS queries from VPC to on-premises, and a rule specifies the domain.
