A domain controller that you must contact when you add, remove or change a domain name is which role?

• A. Domain Naming Master
• B. Schema Master
• C. PDC Emulator Master
• D. Infrastructure Master

Answer: (A)

Domain naming changes in an Active Directory forest are managed by a single FSMO role called the Domain Naming Master. This server has forest-wide authority over the namespace, ensuring that a domain name is unique across the entire forest and coordinating the addition, removal, or renaming of domains so every domain controller agrees on the new structure. The other FSMO roles have different duties: the Schema Master controls updates to the AD schema, the PDC Emulator handles time synchronization and password-related operations, and the Infrastructure Master deals with updating cross-domain object references. None of those manage forest-wide domain-name changes, so the Domain Naming Master is the one you contact for adding, removing, or changing a domain name.
