Your company has an Active Directory Domain Services (AD DS) domain. You have a main office and a branch office that are connected by a slow WAN link. All servers are located in the main office. You virtualize an application by using Microsoft Application Virtualization (App-V) 4.5. The available bandwidth is not sufficient for branch office users to run the virtualized application.

• A、On each App-V server in the main office, upgrade the App-V desktop clients to 4.6.
• B、On each client computer in the branch office, upgrade the App-V desktop clients to 4.6.
• C、On each client computer in the branch office, install the application by using Windows Installer (.msi) files created by the App-V Sequencer.
• D、In the Microsoft System Center Application Virtualization Management Server, configure an Application Virtualization file server for the main office.
