Your network contains an Active Directory domain named contoso.com. The domain contains servers that run
Windows Server 2012.
You plan to deploy a Remote Desktop Virtualization Host (RD Virtualization Host) that will contain five virtual
desktops. The requirement of each virtual desktop is shown in the following table.

You need to identify which virtual desktop or virtual desktops require a virtual SCSI controller.
Which virtual desktop or desktops should you identify? (Each correct answer presents part of the solution.
Choose all that apply.)

A.
VD1

B.
VD2

C.
VD3

D.
VD4

E.
VD5

Explanation:
VD4:
Hot adding / removing storage feature is only available on the virtual SCSI controller of a VM.
VD5:
HyperV does support a maximum number of 4 SCSI controllers per virtual Machine – if the integration services
are installed within the guest OS.
Each virtual SCSI controller can handle up to 64 disks. (you cannot boot off from the SCSI though)
On the IDE side there is a limitation to 2 virtual IDE controllers.
