Exam AZ-800 topic 4 question 40 discussion

Access SRV1: Use Remote Desktop Connection (RDC) to connect to SRV1 if needed2. Open DNS Manager: On SRV1, open the DNS Manager from the Administrative Tools. Configure Conditional Forwarder: In DNS Manager, right-click on "Conditional Forwarders" and select "New Conditional Forwarder." Enter "contoso.com" as the domain name. Add the IP address of DC1 as the forwarding server. Verify Root Hints Configuration: In DNS Manager, right-click on the server name and select "Properties." Go to the "Root Hints" tab and ensure it is correctly configured with root servers. Test Configuration: Use tools like nslookup to verify that queries for contoso.com are resolved by DC1 and other queries use root hints.

Root hints are enabled by default UNLESS they're disabled. Instead configure your DNS server to not use root hint name server by selecting the Disable recursion server option in the DNS Manager console Advanced tab. I guess you need to check advanced tab on dns console and make sure disable recursion is not checked.

Actually to be simpler, you are setting this up as a secondary zone, set up dc2 to allow zone transfers to this secondary server, and let it use root hints.
