What should you configure in a Group Policy object (GPO)?

Your network contains an Active Directory domain named contoso.com. All domain
controllers run Windows Server 2012 R2. The domain contains 500 client computers that run
Windows 8 Enterprise.
You implement a Group Policy central store.
You have an application named App1. App1 requires that a custom registry setting be

What should you configure in a Group Policy object (GPO)?

A.
The Software Installation settings

B.
The Administrative Templates

C.
An application control policy

D.
The Group Policy preferences

Explanation:
Open the Group Policy Management Console. Right-click the Group Policy object (GPO)
that should contain the new preference item, and then click Edit.
In the console tree under Computer Configuration or User Configuration, expand the
Preferences folder, and then expand the Windows Settings folder.
Right-click the Registry node, point to New, and select Registry Item .
Group Policy preferences provide the means to simplify deployment and standardize
configurations. They add to Group Policy a centralized system for deploying preferences
(that is, settings that users can change later).
You can also use Group Policy preferences to configure applications that are not Group
Policy-aware. By using Group Policy preferences, you can change or delete almost any
registry setting, file or folder, shortcut, and more. You are not limited by the contents of
Administrative Template files. The Group Policy Management
Editor (GPME) includes Group Policy preferences.
