Your network contains several branch offices. All servers run Windows Server 2008 R2. Each branch office
contains a domain controller and a file server.
The DHCP Server server role is installed on the branch office domain controllers. Each office has a branch
office administrator.
You need to delegate the administration of DHCP to meet the following requirements:
Allow branch office administrators to manage DHCP scopes for their own office.
Prevent the branch office administrators from managing DHCP scopes in other offices.
Minimize administrative effort.
What should you do?

A.
In the Active Directory domain, add the branch office administrators to the Server Operators builtinlocal
group.

B.
In the Active Directory domain, add the branch office administrators to the Network Configuration Operators
builtin local group.

C.
In each branch office, migrate the DHCP Server server role to the file server. On each file server, add the
branch office administrator to the DHCP Administrators local group.

D.
In each branch office, migrate the DHCP Server server role to the file server. In the Active Directory domain,
add the branch office administrators to the DHCP Administrators domain local group.

Explanation:
DHCP Administrators group have the minimal right toperform the tasks, while Server Operators group
(administrating domain servers) and Network Configuration Operators group (managing some configurationof
networking features) have more rights than necessary.
Moreover, branch office administrators ONLY are allowed to manage DHCP scopes on their own offices. DHCP
Administrators local group is required. However, local group cannot be used in a domain controller. Hence,
DHCP servers need to be migrated to non-DC member servers first.
