Which FSMO role is responsible for updating cross-domain object references when objects are moved between domains?

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

Answer: (D)

Cross-domain object references are updated by the Infrastructure Master. In a forest with multiple domains, objects are often referenced from other domains, and when an object moves to a different domain its distinguished name changes. The Infrastructure Master ensures these cross-domain references are updated during replication so permissions, group memberships, and ACLs remain accurate after the move. The other FSMO roles handle different tasks: the RID Master issues SIDs within a domain; the Domain Naming Master manages forest-wide domain additions/removals; the PDC Emulator acts as the primary domain controller for password changes, time, and certain policy-related functions.
