单选题Your network consists of a single Active Directory domain. The functional level of the domain is Windows Server 2003. All servers run Windows Server 2003 Service Pack 2 (SP2). The network contains 10 file servers. Each file server hosts a share named Apps.On each file server, a local group named App-install-local has permissions to the Apps share. A global group named App-install-global belongs to the App-install-local group on each file server. App-install-global is used only to control permissions for the Apps share.You create a global group named Helpdesk.You need to provide the Helpdesk group access to the Apps share on each file server. The Helpdesk group must have the same permissions as the App-install-global group. You must achieve this goal by using the minimum amount of administrative effort.What should you do? （）A
Add the Helpdesk group to the App-install-global group.B
Add the Helpdesk group to the App-install-local group on each file server.C
Convert the App-install-global group to a universal group. Add the App-install-global group to the Helpdesk group.D
Convert the Helpdesk group to a universal group. Add the Helpdesk group to the App-install-local group on each file server.
