Question 12 of 13
You are the network administrator for westsim.com. The network consists of a single Active Directory
domain . All the servers run Windows Server 2012 R2 and all the clients run Windows 8.
You are responsible for a server named HV1 that has the Hyper-V role installed . HV1 hosts a virtual machine
that runs a custom Web application that is in use 24 hours a day. The virtual machine has one hard drive that
is hosted on a 127GB expanding virtual hard drive (.vhd). The server is running out of room. Management
would like to upload 100 GB of new media files for use in the Web application . You need to provide more
storage space inside the virtual machine while minimizing the downtime for the custom Web application.
What should you do?
0 Add a new virtual hard drive (.vhd) to the existing IDE controller.
0 Add a new virtual hard drive (.vhd) to a new IDE controller.
@ Add a new virtual hard drive (.vhd) to a SCSI controller.
0 Edit the existing virtual hard drive (.vhd) file.
Explanation
Add a new virtual hard drive (.vhd) to a SCSI controller. A new feature of Windows Server 2008 R2 and later is support for
Dynamic Virtual Machine Storage, which allows hot plug-in and hot removal of the storage on a SCSI controller of the
virtual machine. Physical machines that support hot swapping of drives only do so on SCSI controllers, and the same is
true of virtual machines. Therefore, you must add the new virtual hard drive (.vhd) to a SCSI controller, which will allow
you to add the new .vhd without having to shut down the virtual machine, eliminating any downtime for the custom Web
app.
Adding a new virtual hard drive (.vhd) to an IDE controller, whether the existing controller or a new one, would require a
reboot of the virtual machine. Editing the existing file would allow you to convert the expanding virtual hard drive (.vhd) to
a fixed size virtual hard drive, but would not increase the available space. Generally, conversion from a dynamically
expanding .vhd to a fixed size .vhd is done for performance issues, since a fixed size .vhd does not require the processor
to expand the .vhd as storage requirements increase.
