Which FSMO role is used when adding or removing domains in the forest?

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

Answer: (A)

Coordinating changes to the forest-wide domain namespace is handled by a single authoritative master. The Domain Naming Master is the FSMO role responsible for adding or removing domains within the forest, ensuring the domain name is unique across the entire forest and updating the forest’s naming context accordingly. When you add a new domain, the wizard contacts this master to validate the name and perform the creation; when you remove a domain, this master coordinates the necessary updates to the forest structure. The other FSMO roles serve different purposes (schema changes, cross-domain object references, and domain-specific operations like time and password handling), so they don’t govern domain creation or deletion. If the Domain Naming Master isn’t available, you can’t safely add or remove domains.
