You have a server named Server1 that runs Windows Server 2012 R2. Server1 has the Hyper-V server role
installed.
The disks on Server1 are configured as shown in the exhibit. (Click the Exhibit button.)
You create a virtual machine on Server1.
You need to ensure that you can configure a pass-through disk for the virtual machine.
What should you do?
A.
Convert Disk 1 to a GPT disk.
B.
Convert Disk 1 to a dynamic disk.
C.
Delete partition E.
D.
Take Disk 1 offline.

Passthrough Disk Configuration Hyper-V allows virtual machines to access storage mapped directly to the
Hyper-V server without requiring the volume be configured. The storage can either be a physical disk internal to
the Hyper-V server or it can be a Storage Area Network (SAN) Logical Unit (LUN) mapped to the Hyper-V
server. To ensure the Guest has exclusive access to the storage, it must be placed in an Offline state from the
Hyper-V server perspective.
Additionally, this raw piece of storage is not limited in size so, hypothetically, it can be a multi terabyte LUN.
After storage is mapped to the Hyper-V server, it will appear as a raw volume and will be in an Offline state
(depending on the SAN Policy (Figure 1-1)) as seen in Figure 1.
We stated earlier that a disk must be Offline from the Hyper-V servers’ perspective in order for the Guest to
have exclusive access. However, a raw volume must first be initialized before it can be used. To accomplish
this in the Disk Management interface, the disk must first be brought Online. Once Online, the disk will show as
being Not Initialized (Figure 2).
Right-click on the disk and select Initialize Disk (Figure 3)
Select either an MBR or GPT partition type (Figure 4).
Once a disk is initialized, it can once again be placed in an Offline state. If the disk is not in an Offline state, it
will not be available for selection when configuring the Guest’s storage. In order to configure a Pass-through
disk in a Guest, you must select Attach a virtual disk later in the New Virtual Machine Wizard (Figure 5).
If the Pass-through disk will be used to boot the operating system, it must be attached to an IDE Controller.
Data disks can take advantage of SCSI controllers. In Figure 6, a Passthrough disk is attached to IDE
Controller 0.
Note: If the disk does not appear in the drop down list, ensure the disk is Offline in the Disk Management
interface (In Server CORE, use the diskpart.exe CLI). Once the Pass-through disk is configured, the Guest can
be started and data can placed on the drive. If an operating system will be installed, the installation process will
properly prepare the disk. If the disk will be used for data storage, it must be prepared in the Guest operating
system before data can be placed on it. If a Pass- through disk, being used to support an operating system
installation, is brought Online before the Guest is started, the Guest will fail to start. When using Pass-through
disks to support an operating system installation, provisions must be made for storing the Guest configuration
file in an alternate location. This is because the entire Pass-through disk is consumed by the operating system
installation. An example would be to locate the configuration file on another internal drive in the Hyper-V server
itself. Or, if it is a cluster, the configuration file can be hosted on a separate cluster providing highly available file
services. Be aware that Pass-through disks cannot be dynamically expanded. Additionally, when using Passthrough disks, you lose the capability to take snapshots, and finally, you cannot use differencing disks with
Pass-through disks.
