Which master handles removing an object from its domain during an object move?

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

Answer: (A)

The important idea is how Object Identity is controlled within a domain. When an object moves to another domain, it effectively becomes a new object in that destination domain: a fresh security identifier (SID) is required, and that SID is issued by the domain’s RID Master. The RID Master is responsible for allocating the Relative IDs that form the object’s SID within a domain, so during a move the destination domain relies on its RID Master to grant a new RID for the moved object. This makes the RID Master the key player in enabling the move because it ensures the moved object can exist in the new domain with a unique identifier, while the source domain’s copy is removed as part of the move. The other masters handle different forest and domain-wide functions (schema changes, forest-wide domain naming, time/password-related duties, or cross-domain reference updates) and do not oversee the creation/removal of objects during a move in the same way.
