Which FSMO role is described as the one that issues unique relative IDs to new objects within a domain?

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

Answer: (A)

The essential idea is how new objects get their unique identifiers in Active Directory. Each object receives a Security Identifier composed of the domain’s SID plus a relative ID. The authority that issues those relative IDs is the RID Master. It allocates blocks of RIDs to domain controllers, and when a DC creates a new object, it uses an RID from its pool to ensure the resulting SID is unique within the domain. If the RID Master isn’t available, new objects can’t be issued new RIDs, halting creation until a RID block can be obtained again. The other FSMO roles handle different tasks: the Domain Naming Master manages adding or removing domains in the forest, the PDC Emulator handles certain authentication-related functions and time synchronization, and the Schema Master governs updates to the AD schema.
