How to create split-horizon DNS?

Hi

I have a single-domain forest in Active Directory, in my LAN. Servers are 2012 R2. I have just built a DMZ envronment on a different network and now want to implement a split-DNS system with the DMZ (where I have a DNS server implemented with a zone for the domain name).

My LAN network is global.domain.com (AD)
DMZ is domain.com

Is this the config reequired?

Thanks!
