Your company has three offices. Each office is configured as an Active Directory site.
The network consists of one Active directory domain.
All domain controllers run Windows Server 2008.
The company has five departments.
You use a domain-level Group Policy object (GPO) to install Microsoft Office on all client computers.
You need to deploy a GPO strategy to meet the following requirements:
– Install a custom application in one of the departments.
– Restrict access to removable storage devices for all users.
– Implement separate Windows Internet Explorer proxy settings for each physical location.
– The strategy must maintain all settings applied by the existing GPOs.
What should you do?

A.
Create a new group for each department. Create a new GPO for each site. Create a new GPO for the domain and use the GPO to install the custom application.

B.
Create a new organizational unit (OU) for each department. Create a new GPO for each site and a new GPO for the domain. Create a GPO for one department OU and use the GPO to install the application.

C.
Create a new organizational unit (OU) for each department. Create a single GPO for all the sites and a new GPO for the domain. Create a single GPO for each department OU and use the GPO to install the custom application.

D.
Create a new child domain for each department. Create a new GPO for each site and a new GPO for each new child domain. Create a single GPO for all the new child domains and use the GPO to install the custom application.
