Your network contains a server named Server1 that runs Windows Server 2012. Server1 has the Hyper-V
server role installed.
Server1 hosts four virtual machines named VM1, VM2, VM3, and VM4.
Server1 is configured as shown in the following table.
You plan to schedule a complete backup of Server1 by using Windows Server Backup.
You need to ensure that the state of VM1 is saved before the backup starts.
What should you configure?
A.
NUMA topology
B.
Resource control
C.
Resource metering
D.
Virtual Machine Chimney
E.
The VLAN ID
F.
Processor Compatibility
G.
The startup order
H.
Automatic Start Action
I.
Integration Services
J.
Port mirroring
K.
Single-root I/O virtualization

Backup
Operations in Hyper-V
No
VSS Writer Available?
In some cases, you need an Application-consistent backup but there is no VSS writer available. One
example of this is MySQL. Hyper-V backups of virtual machines containing MySQL will always result in
either a crashconsistent or an image-level backup. For MySQL, the latter is probably acceptable as
MySQL doesn’t perpetually expand the log file. However, if you’re using MySQL within a VSS-aware VM,
then a Hyper-Vbased backup tool is going to take a crash-consistent backup. MySQL (like any otherdatabase system) isn’t always recoverable from a crash-consistent backup; tool is going to take a crashconsistent backup. MySQL (like any
other database system) isn’t always recoverable from a crash-consistent backup; even when recovery is
possible, it may be painful. MySQL is just one example; any number of line-of-business Applications
could tell a similar tale. In the case of MySQL, one solution is to find a guest-level backup Application
that is MySQL- aware and can back it up properly. For Applications for which no backup Application has
a plug-in, you may need to have pre- and post-backup scripts that stop services or close Applications. If
brief downtime is acceptable, you can disable the Backup item in Hyper-V Integration Services, thereby
forcing Hyper-V to save
the state of the VM during backup. This technique results in an image-level backup and can be used on
any Application that doesn’t have a VSS writer.
That’s correct
TechNet Article on Integration Services:

Hyper-V integration services, are a bundled set of software which, when installed in the virtual machine improves integration between the host server and the virtual machine. Integration services come pre-installed in most supported guest operating systems.
Integration Services enables HyperV to do the following on the guest OS:
Operating System Shutdown
Time Synchronization
Data Exchange
Heart Beat
Backup (volume snapshot using Volume Shadow Copy)
Guest Services (Copy files to guest OS without a network connection)
