After reviewing the information shown in the exhibits, which option gives the best conclusion about this workload?

  • A VM is CPU constrained since the hypervisor cannot provide the required resources.
  • B VM is CPU constrained because more CPU needs to be added to the VM.
  • C VM is Storage constrained, because the workload is waiting for storage access.
  • D VM is not CPU constrained, because the VM is not running, a multithreaded application.
Explanation

A four-vCPU VM at roughly 25% total CPU utilization has the equivalent of only one vCPU fully utilized. That pattern is consistent with a workload that is not using multiple execution threads, rather than a VM-wide CPU-resource constraint. The reported storage I/O latency of 2.33 ms and zero controller IOPS do not indicate that the workload is waiting for storage access.
