In Windows Server 2022, a DNS deployment that serves both internal and external clients from a single DNS server is commonly called what?

• A. Split-brain
• B. Split-horizon
• C. Dual-zone
• D. Unified DNS

Answer: (B)

Split-horizon DNS is about giving different DNS answers based on where the query comes from. In Windows Server 2022 you can implement this on a single DNS server by using DNS policies that check the client’s subnet and apply different records accordingly. That lets internal clients resolve to private/internal addresses while external clients see public addresses for the same domain, all from one server. This setup centralizes DNS management while keeping the internal namespace protected from the external network. The other terms don’t fit: split-brain describes two separate servers with conflicting data, not a single-server view difference; dual-zone would imply two separate zones rather than one server offering different responses; unified DNS isn’t a standard term for this scenario.
