Q. Where should the primary DNS for a Read Only Domain Controller (RODC) that's a DNS server point?

A. An RODC that's a DNS server should point to itself for the primary DNS server. DNS servers in a hub location should be the secondary/alternate DNS servers. By default, when you promote a RODC that's a DNS server, the RODC adds itself at the end of the alternate DNS server list as 127.0.0.1. You should modify this manually or via Group Policy after creation.
