Question
You have an Active Directory Domain Services (AD DS) domain that contains the domain controllers shown in the following table.
| Name | Operations master role |
|---|---|
| DC1 | Schema master |
| DC2 | Infrastructure master |
| DC3 | Domain naming master |
| DC4 | PDC emulator, RID master |
The domain contains an app named App1 that uses a custom application partition to store configuration data.
You decommission App1.
When you attempt to remove the custom application partition, the process fails.
Which domain controller is unavailable?
- A. DC1
- B. DC2
- C. DC3 Correct
- D. DC4
Explanation
The Domain Naming Master FSMO role is required to add or remove application partitions in a forest. Since the process of removing the custom application partition fails, it indicates that DC3, which holds this role, is unavailable.
