What is the Domain Naming Master responsible for?

• A. Replicating password changes
• B. Managing domains and application partitions in the forest
• C. Processing RID pool requests from all DCs
• D. Hosting file shares

Answer: (B)

The Domain Naming Master is a forest-wide control point that coordinates the naming of domains and application partitions. It ensures every domain name and every application partition name is unique across the entire Active Directory forest, and it is the one authority that must approve and complete any addition or removal of domains or application partitions. Because this is a single role for the whole forest, if the holder isn’t available, you can’t extend the forest with new domains or partitions. This responsibility is distinct from password changes, RID pool management, or hosting file shares, which are handled by other mechanisms.
