Which domain controller role is responsible for time synchronization in a domain?

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

Answer: (A)

Time synchronization in a Windows domain relies on a single authoritative time source, provided by the PDC Emulator. The PDC Emulator in the domain acts as the primary time server that distributes time to all other domain controllers and domain-joined clients. It should be configured to sync with a reliable external time source (such as an NTP server), and the rest of the domain's devices will follow its time. The other FSMO roles—Schema Master, Domain Naming Master, Infrastructure Master—manage schema changes, domain naming, and cross-domain object references, respectively, and do not control time. So, the PDC Emulator is the best answer because it is the designated time authority for the domain.
