You have a server named Server1 that runs Windows Server 2012. Server1 has the Hyper- V server role
installed.
An iSCSI SAN is available on the network.
Server1 hosts four virtual machines named VM1, VM2,VM3, and VM4.
You create a LUN on the SAN.
You need to provide VM1 with access to the LUN. Thesolution must prevent other virtual machines from
accessing the LUN.
What should you configure?

A.
A fixed-size VHDX

B.
A fixed-size VHD

C.
A dynamically expanding VHD

D.
A dynamically expanding VHDX

E.
A pass-through disk

Explanation:
You can use physical disks that are directly attached to a virtual machine as a storage option on
themanagement operating system. This allows virtualmachines to access storage that is mapped directlyto
theserver running Hyper-V without first configuringthe volume. The storage can be either a physical disk which
isinternal to the server, or a SAN logical unit number (LUN) that is mapped to the server (a LUN is a
logicalreference to a portion of a storage subsystem). The virtual machine must have exclusive access to
thestorage, so the storage must be set in an Offline state in Disk Management. The storage is not limited
insize, so it can be a multiterabyte LUN. When using physical disks that are directly attached to a virtual
machine, you should be aware of the following:
This type of disk cannot be dynamically expanded.
You cannot use differencing disks with them.
You cannot take virtual hard disk snapshots.
Att:
If you are installing an operating system on the physical disk and it is in an Online state before the
virtualmachine is started, the virtual machine willfail to start. You must store the virtual machine configuration
file inan alternate location because the physical disk is used by the operating system installation. For example,
locate the configuration file on another internal drive on the server running Hyper-V.
