How many operational roles are available on a Domain Controller?

• A. Five
• B. Three
• C. Four
• D. Six

Answer: (A)

Five operational roles exist in Active Directory, known as FSMO roles. They’re specialized duties that require a single master to prevent conflicts. Of these, two are forest-wide: Schema Master and Domain Naming Master. The other three are domain-wide: RID Master, PDC Emulator, and Infrastructure Master. So, a Domain Controller can hold a total of five FSMO roles. A DC can host more than one role at the same time, and roles can be transferred as needed.
