When determining how to realize optimal performance for a Primary Domain Controller (PDC), which of the following factors is relevant?

A.
The time that it takes for a PDC to replicate a database over all domain controllers.

B.
The quantity of network traffic generated by the synchronization of domain
controllers.

C.
Both of the above.

D.
None of the above.

Explanation:
When determining how to realize optimal performance for a Primary Domain Controller (PDC), the relevant defining factors is the time that it takes for a PDC to replicate a database over all domain controllers, and the quantity of network traffic generated by the synchronization of domain controllers.
