You have a server named Server1 that runs Windows Server 2012 R2. 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, VM4.
You create a LUN on the SAN.
You need to provide VM1 with access to the LUN. The solution must prevent other virtual machines from accessing the LUN.
What should you configure?
A. A fixed-size VHDX
B. A dynamically expanding VHDX
C. A fixed-size VHD
D. A pass-through disk
E. A dynamically expanding VHD
Correct Answer: D
Explanation/Reference:
Explanation:
You can use physical disks that are directly attached to a virtual machine as a storage option on the management operating system. This allows virtual machines to access storage that is mapped directly to the server running Hyper-V without first configuring the volume. The storage can be either a physical disk which is internal to the server, or a SAN logical unit number (LUN) that is mapped to the server (a LUN is a logical reference to a portion of a storage subsystem). The virtual machine must have exclusive access to the storage, so the storage must be set in an Offline state in Disk Management. The storage is not limited in size, so it can be a multi-terabyte 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 virtual machine is started, the virtual machine will fail to start.
You must store the virtual machine configuration file in an 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.
