Which of the following describes the PDC Emulator role in an Active Directory domain?

Explanation:
The PDC Emulator’s defining job is to act as the domain’s time source. Time synchronization is crucial for Kerberos authentication, and the domain’s machines and other domain controllers use the PDC Emulator as the authoritative clock to stay in sync. When clocks are aligned, tickets and authentication flow reliably; drift can cause failures. So describing it as the domain’s time server is the best-fit explanation. The other roles mentioned (DNS zone transfers, storing the Global Catalog, handling password resets) are not the PDC Emulator’s primary function.
