Desktop virtualization (also called virtual desktop infrastructure, or VDI)

A) Using public telecom infrastructure to provide remote offices or users with secure access to their organization's network

B) Isolating a logical OS instance from the client that is used to access it

C) Masking server resources -- including the number and identity of individual physical servers, processors and OSes -- from users

D) Combining available network resources by splitting bandwidth into independent channels that can be assigned to a particular server or device

Correct Answer : Isolating a logical OS instance from the client that is used to access it

Explanation : Desktop virtualization creates virtual desktops with the OS instance executed either locally or remotely. VMware's VDI software, VMware View, makes user desktops into VMs on a thin client, running on ESX/ESXi hosts in vSphere. Additional components manage connection, provisioning, authentication and applications.
