AWS Certified Advanced Networking – Specialty ANS-C00 – Question176

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?

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:

Explanation:
10.1.3.2 is not the DNS server. A DHCP option set is not needed since you are resolving AWS resources from on-premises not from a VPC and those instances are already configured to look to Route 53 DNS.
