Your network contains an Active Directory domain named contoso.com. The domain contains a
member server named Server1. Server1 runs Windows Server 2012 R2 and has the Hyper-V server
role installed.
Server1 hosts 10 virtual machines. A virtual machine named VM1 runs Windows Server 2012 R2 and
hosts a processor-intensive application named App1.
Users report that App1 responds more slowly than expected.
You need to monitor the processor usage on VM1 to identify whether changes must be made to the
hardware settings of VM1.
Which performance object should you monitor on Server1?
A.
Processor
B.
Hyper-V Hypervisor Virtual Processor
C.
Hyper-V Hypervisor Logical Processor
D.
Hyper-V Hypervisor Root Virtual Processor
E.
Process
Explanation:
In the simplest way of thinking the virtual processor time is cycled across the available logical
processors in a round-robin type of fashion. Thus all the processing power gets used over time, and
technically nothing ever sits idle.To accurately measure the processor utilization of a guest operating system, use the “\Hyper-V
Hypervisor Logical Processor (Total)\% Total Run Time” performance monitor counter on the HyperV host operating system.

Measure overall processor utilization of the Hyper-V environment using Hyper-V performance monitor counters – For purposes of measuring processor utilization, the host operating system is logically viewed as just another guest operating system. Therefore, the “\Processor(*)\% Processor Time” monitor counter measures the processor utilization of the host operating system only. To measure total physical processor utilization of the host operating system and all guest operating systems, use the “\Hyper-V Hypervisor Logical Processor(_Total)\% Total Run Time” performance monitor counter. This counter measures the total percentage of time spent by the processor running the both the host operating system and all guest operating systems. Use the following thresholds to evaluate overall processor utilization of the Hyper-V environment using the “\Hyper-V Hypervisor Logical Processor(_Total)\% Total Run Time” performance monitor counter:
Less than 60% consumed = Healthy
60% – 89% consumed = Monitor or Caution
90% – 100% consumed = Critical, performance will be adversely affected

Hyper-V Hypervisor Logical Processor(*)\% Total Run Time: To see overall utilization of the processors, including host and virtual machines. The processor in Task Manager on the host shows only CPU use from the root partition itself
Logical shows utilization of both the Host and all VM’s. overall usage of the physical processor
Hyper-V Hypervisor Virtual Processor(*)\% Guest Run Time: To see processor utilization of virtual machines. This is better than looking at a processor within a virtual machine because clock calculation drift can affect the processor utilization information.
Virtual allows you to monitor specific VM.
B.) Virtual processor is correct
Whereas Hyper-V considers a “Virtual Processor” to be one that has been assigned as part of a VM’s configuration, a “Logical Processor” represents the total number of processors on a host system that are managed by Hyper-V.
