Your company’s network has client computers that run Windows 7.
A software vendor releases version 2 of an application that your company uses.
Your company currently uses version 1. Version 1 and version 2 are not compatible.
You plan to deploy version 2 of the application.
You have the following requirements:
Users must be able to run both versions of the application on their computers.
Version 2 must be available when a client computer is not connected to the network.
You need to plan a software deployment process thatmeets the requirements.
What should you do?

A.
Deploy version 2 of the application by using a Microsoft System Center Configuration Manager package.

B.
Deploy version 2 of the application by using a Group Policy Software Installation policy.

C.
Deploy version 2 of the application as a Remote Desktop Services RemoteApp.

D.
Deploy version 2 of the application by using Microsoft Application Virtualization (App-V).

Explanation:
Microsoft Application Virtualization (MS App-V) platform allows applications to be deployed in real- time to any
client from a virtual application server. It removes the need for local installation of the applications. Instead, only
the App-v client needs to be installed on the client machines. All application data is permanently stored on the
virtual application server. Whichever software is needed is either streamed or locally cached from the
application server on demand and run locally.
The App-V stack sandboxes the execution environmentso that the application does not make changes to the
client itself (OS File System and/or Registry).
App-V applications are also sandboxed from each other, so that different versions of the same application can
be run under App-V concurrently.
