Your network has client computers that run Windows 7 Enterprise.
You plan to deploy new administrative template policy settings by using custom ADMX files. You create the
custom ADMX files, and you save them on a network share.
You start Group Policy Object Editor (GPO Editor).
The custom ADMX files are not available in the Group Policy editing session. You need to ensure that the
ADMX files are available to the GPO Editor.
What should you do?

A.
Copy the ADMX files to the % systemroot% \ inf folder on each Windows 7 computer, and then restart the
GPO Editor.

B.
Set the network share permissions to grant all Windows 7 users Read access for the share.

C.
Copy the ADMX files to the %systemroot% \ system32 folder on each Windows 7 computer, and then
restart the GPO Editor.

D.
Copy the ADMX files to the central store, and then restart the GPO Editor.

Explanation:
To take advantage of the benefits of .admx files, you must create a Central Store in the SYSVOL folderon a
domain controller.
The Central Store is a file location that is checked by the Group Policy tools. The Group Policy toolsuse any .
admx files that are in the Central Store.
The files that are in the Central Store are later replicated to all domain controllers in the domain.
