Your company, which is named Contoso, Ltd., has a main office and two branch offices. The
main office is located in North America. The branch offices are located in Asia and Europe.
You plan to design an Active Directory forest and domain infrastructure.
You need to recommend an Active Directory design to meet the following requirements:
The contact information of all the users in the Europe office must not be visible to the users
in the other offices.
The administrators in each office must be able to control the user settings and the computer
settings of the users in their respective office.
The solution must use the least amount of administrative effort.
What should you include in the recommendation?
A.
One forest that contains three domains
B.
Three forests that each contain one domain
C.
Two forests that each contain one domain
D.
One forest that contains one domain

A single domain (answer D) is enough to satisfy all requirements (by using OUs and setting proper permissions); all other solutions are much more complex to implement and manage, and thus they don’t “use the least amount of administrative effort”.
Also, if one was to actually use multiple domains, there would still be no reason to place them in multiple forests. Answers B and C are just plain excessive.
