70-246 · Question #91

You need to recommend a solution to resolve the monitoring issue for the Hyper-V hosts. Which performance object should you recommend?

The correct answer is A. Hyper-V Hypervisor Logical Processor. The 'Hyper-V Hypervisor Logical Processor' performance object provides accurate CPU utilization data at the hypervisor level for monitoring Hyper-V hosts, reflecting true physical processor consumption.

Why each option

The 'Hyper-V Hypervisor Logical Processor' performance object provides accurate CPU utilization data at the hypervisor level for monitoring Hyper-V hosts, reflecting true physical processor consumption.

AHyper-V Hypervisor Logical ProcessorCorrect

The 'Hyper-V Hypervisor Logical Processor' object measures CPU time consumed by the hypervisor for each logical processor, giving an accurate picture of overall host CPU load across all partitions. This is the correct counter for monitoring physical host processor health on Hyper-V servers because it accounts for all workloads running on the hypervisor, not just the root partition.

BProcessor

The standard 'Processor' object reflects only the root partition's CPU usage and does not account for CPU cycles consumed by guest VMs, making it inaccurate for Hyper-V host monitoring.

CHyper-V Hypervisor Root Virtual Processor

'Hyper-V Hypervisor Root Virtual Processor' tracks CPU usage only for the root (management) partition's virtual processor, not the full hypervisor logical processor utilization.

DHyper-V Hypervisor Virtual Processor

'Hyper-V Hypervisor Virtual Processor' monitors CPU usage of guest VM virtual processors, not the physical host's overall hypervisor-level processor performance.
