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.
Hyper-V Hypervisor Logical Processor
B.
Hyper-V Hypervisor Root Virtual Processor
C.
Processor
D.
Hyper-V Hypervisor Virtual ProcessorE. Process

Hyper-V Hypervisor Logical Processor is concerned with monitoring the aggregated CPU usage of the logical CPU cores in the host machine by all running VMs on a given Hyper-V host system.
The Hyper-V Hypervisor Virtual Processor counter is aimed specifically at individual virtual CPU instances configured in your VMs.
The question is asking you to determine CPU usage for the VM and whether configuration changes to the VM itself are required (i.e, the possibility of another vCPU).
