You are a security administrator for your company. The network consists of a single Active Directory domain. All servers run Windows Server 2003. All servers are members of the domain.

The company plans to deploy a new application named App1. The application runs on servers. To test the compatibility between App1 and other applications that run on the servers, you need to change several file and registry permissions in the Windows folder on the servers. A security template named TestPerms contains the file and registry permissions that need to be set for the application testing. You create a new Group Policy object (GPO) named TestApp. You import the TestPerms security template into the TestApp GPO. You link the TestApp GPO to an organizational unit (OU) that contains only the servers that are used for the test.

You need to ensure that the file and registry permissions are set to the permissions in the TestPerms security template only during application testing. What should you do when the application testing ends?

A.
Disable the computer configuration settings in the TestApp GPO.

B.
Disable the TestApp GPO link to the OU.

C.
Unlink the TestApp GPO from the OU.

D.
Delete the TestApp GPO, and then run the gpupdate.exe /sync command.

E.
Delete the TestApp GPO, and then apply a security template that contains the original permissions.
