AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 117

You have a hybrid infrastructure and you have configured your own DNS server on an EC2 instance in your 10.1.3.0/24 subnet. This subnet resides on the VPC
10.1.0.0/16. You need your data center to be able to resolve Route 53 queries in your private hosted zone. What do you need to do to accomplish this?

Answer options

• A. Disable the source/destination check flag for the DNS instance.
• B. Configure your DNS server to forward queries for the private hosted zone to 10.1.3.2.
• C. Configure your DNS server to forward queries for the private hosted zone to 10.1.0.2.
• D. Configure the VPC DHCP option set in the VPC to point to the EC2 DNS server.

Correct answer: C

Explanation

The correct answer is C because configuring the DNS server to forward queries to 10.1.0.2 allows it to communicate properly with the private hosted zone in Route 53. Options A and D do not directly address the requirement for forwarding DNS queries, while option B points to an incorrect IP address that does not facilitate access to the private hosted zone.
