Question
Your network contains an Active Directory Domain Services (AD DS) domain. The domain contains the domain controllers shown in the following table.
| Name | Description |
| --- | --- |
| DC1 | Has the schema master, infrastructure master, and domain naming master roles |
| DC2 | Has the PDC emulator and RID master roles and is a global catalog server |
| DC3 | None |
You need to configure DC3 to be the authoritative time server for the domain.
Which operations master role should you transfer to DC3, and which console should you use? To answer, select the appropriate options in the answer area.
NOTE: Each correct selection is worth one point.
Explanation
Role: PDC emulator — In an AD DS forest the domain controller holding the PDC emulator role in the forest root domain is, by default, the authoritative time source for the domain hierarchy; every other DC and domain member synchronizes its clock up the chain to it through the Windows Time service (W32Time). So making DC3 the authoritative time server means transferring the PDC emulator role to DC3. The other roles are unrelated to time: the RID master hands out RID pools, the infrastructure master maintains cross-domain object references, and the domain naming master and schema master are forest-wide roles governing domain additions and schema changes.
Console: Active Directory Users and Computers — The three domain-level operations master roles (PDC emulator, RID master and infrastructure master) are transferred in Active Directory Users and Computers: connect to DC3 with Change Domain Controller, right-click the domain, choose Operations Masters, and use the PDC tab to change the role holder. Active Directory Domains and Trusts only transfers the domain naming master, Active Directory Sites and Services manages sites and replication (no role transfer), and Active Directory Administrative Center does not provide an operations-master transfer interface.
