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.

VM3 is used to test Applications.
You need to prevent VM3 from synchronizing its clock to Server1.
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

Explanation:
By default when you install the Integration Services/Components you get time synchronization with the host OS,
here is how to disable ongoing time synchronization.
When you install the integration services/components in Hyper-V virtual machine you get a
set of services installed and enabled by default.
Operating system shutdown
Time synchronization
Data exchange heartbeat
Backup via VSS
If you do not want the virtual machine to continuously synch its time to the Hyper-V host using the integration
service, you can disable the integration service from the Hyper-V manager.
Open up the settings for the VM
Under Management, highlight the Integration Services option and you will get a list of the Integration
Services installed and enabled Uncheck the Time Synchronization service and press App1y.
The virtual machine will now not sync its time withthe Hyper-V host on a continuous basis….BUT it will always
sync once at power on. This is required to boot strap the timer inside the virtual machine
