Microsoft 70-411 Exam – Q12

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

Correct Answer: B

Explanation:
Logical Processor: A thread of execution on a physical processing unit which can be a core or a thread on a symmetric multi-threaded (SMT) system.
Virtual Processor: A virtualized instance of a logical processor exposed to virtual machines.

To view CPU usage information for virtual machines running on a server running Hyper-V, use Performance and Reliability Monitor to view the data from Hyper-V performance counters. To open Performance and Reliability Monitor, click Start, click Run, and then type perfmon.

The following performance counters provide information when viewed on the management operating system (the operating system that runs the Hyper- V role):

Hyper-V Hypervisor Logical Processor % Guest Run time: Identifies how much of the physical processor is being used to run the virtual machines. This counter does not identify the individual virtual machines or the amount consumed by each virtual machine.

Hyper-V Hypervisor Virtual Processor % Guest Run time: Identifies how much of the virtual processor is being consumed by a virtual machine.
