CORRECTED (Previously C) You have a server named LON-DC1 that runs Windows Server 2012 R2. An
iSCSI virtual disk named VirtualiSCSI1.vhd exists on LON-DC1 as shown in the exhibit. (Click the Exhibit
button.)
You create a new iSCSI virtual disk named VirtualiSCSI2.vhd by using the existing itgt iSCSI target.
VirtualiSCSIl.vhd is removed from LON-DC1.
You need to assign VirtualiSCSI2.vhd a logical unit value of 0.
What should you do?
A.
Modify the properties of the itgt ISCSI target.
B.
Modify the properties of the VirtualiSCSI2.vhd iSCSI virtual disk.
C.
Run the Set-VirtualDisk cmdlet and specify the -Uniqueld parameter.
D.
Run the iscsicli command and specify the reportluns parameter.
E.
Run the Add-IscsiVirtualDiskTargetMapping cmdlet and specify the -Lun parameter. (If this one is on the
exam, choose this one)
Explanation:
Set-VirtualDisk is for VHD drives but not for ISCSI VHDs. You can modify the LUN number on the properties of
the VHD by right clicking it and selecting properties in the ISCI management screen.Add-IscsiVirtualDiskTargetMapping also lets you modify the lun number.

Set-VirtualDisk
Modifies the attributes of an existing virtual disk.
Applies To: Windows Server 2012 R2
-UniqueId<String>
Specifies an ID used to uniquely identify a Disk object in the system. The ID persists through restarts.
Note: Logical unit numbers (LUNs) created on an iSCSI disk storage subsystem are not directly assigned to a
server. For iSCSI, LUNs are assigned to logical entities called targets.
The answer would be E or Modify the properties of the iscsi virtual disk. The set-virtualdisk cmdlet does not function for iscsi virtual disks.

The Add-IscsiVirtualDiskTargetMapping cmdlet assigns a virtual disk to an iSCSI target. Once a virtual disk has been assigned to a target, and after the iSCSi initiator connects to that target, the iSCSI initiator can access the virtual disk. All of the virtual disks assigned to the same iSCSI target will be accessible by the connected iSCSI initiator.

So, the correct answer is E

I’m leaning towards the provided answer of B.
The iSCSI vhd has already been assigned, so we are modifying a drive that is already target mapped.
The LUN of an assigned iSCSI vhd can be changed in the properties of the iSCSI virtual disk.

Actually, I am positive of the answer being B.

Right clic virtual disk, select properties, specify the LUN #, and click OK.

To all who are wondering: Both B and E answers are true. Take note that in a normal exam question these two answers are unlikely to be put in the same list. But if so you prob. have to go for the powershell one.
By the way I’ve tested both in a lab. And the confusing part is the “add-“part of the command. Which makes you think you are creating something new. but actually you are modifying the properties. It would have been easier if Microsoft made it a “Set” command.
