Which of the following pairings correctly maps a master role to its described responsibility?

Which of the following pairings correctly maps a master role to its described responsibility?

• A. A RID master — Removes an object from its domain and moves it to another domain during an object move; B Domain Naming master — Makes changes to the forest wide domain space; C Schema master — Performs updates to the naming context; D PDC Emulator — Time synchronization across the domain and forest.
• B. A RID master — Time synchronization across the domain and forest; B Domain Naming master — The domain controller that you must contact when you add, remove or change a domain name; C Schema master — The domain controller in which you make all schema changes; D PDC Emulator — Updates to the naming context.
• C. A RID master — Updates to the naming context; B Domain Naming master — Time synchronization across the domain; C Schema master — Maintains inter-domain object references; D PDC Emulator — The domain controller that is the time source for the domain.
• D. A RID master — Maintains the integrity of inter-domain object references; B Domain Naming master — The domain controller that is time source for domain naming; C Schema master — Time source for the domain; D PDC Emulator — The domain controller in which you make all schema changes.

Answer: (A)

This question is about the four FSMO roles in Active Directory and what each one is responsible for. Knowing these roles helps you understand how AD maintains consistency across the forest and domain boundaries. The RID Master is in charge of issuing blocks of Relative IDs (RIDs) to domain controllers so every new security principal (user, group, computer) gets a unique SID. It doesn’t move objects between domains; its job is about ensuring unique IDs for new objects within a domain. The Domain Naming Master controls changes to the forest-wide domain namespace, meaning it authorizes the creation and removal of domains within the forest and ensures there are no naming conflicts across the forest. The Schema Master is the one that handles changes to the directory schema. Any modification to object classes or attributes is performed on the Schema Master and then propagated to all domain controllers in the forest. The PDC Emulator acts as the primary time source for the domain (and by extension the forest) and handles several domain-wide functions that require a reliable time reference, such as certain password changes, account lockout processing, and compatibility with older NT4-style behavior. Among the given pairings, the one that best aligns with those specific responsibilities describes the Domain Naming Master as making changes to the forest-wide domain space and the PDC Emulator as the time source for the domain, with the remaining items and their descriptions being less precise. This is why that option is considered the best fit for the described responsibilities.
