Which FSMO role maintains the integrity of inter-domain object references?

• A. Infrastructure Master
• B. Global Catalog
• C. Schema Master
• D. Domain Naming Master

Answer: (A)

Cross-domain object references must stay accurate when objects are moved or renamed in a domain. The Infrastructure Master holds this responsibility. It updates the references in other domains to reflect changes to objects in its own domain, preventing stale links that could break authentication or access across domains. The Global Catalog is used for fast searching and cross-domain logon, but it doesn’t perform cross-domain reference updates. The other FSMO roles serve different functions: the Schema Master controls schema changes, the Domain Naming Master handles adding or removing domains, and the RID Master allocates SIDs within a domain. Therefore, the role that maintains inter-domain reference integrity is the Infrastructure Master.
