Practice question 500 of 506 · hard

An Azure Windows VM responds slowly during workload peaks. Guest CPU utilization is modest, but storage latency rises while throughput approaches the VM size's disk limits. Which investigation is most useful before buying a faster disk tier?

Choose the single best answer.

  1. A.Change host caching immediately without analyzing the workload read/write pattern or the disk and VM caching limits
  2. B.Correlate guest disk latency/queue data with both disk-level and VM-level throughput/IOPS limits and workload demand
  3. C.Consider only average CPU utilization and conclude that the application cannot have a resource bottleneck
  4. D.Consider only the disk SKU maximum and ignore the aggregate limit imposed by the VM size
Show the answer and explanation

✓ Correct answer

  • Correlate guest disk latency/queue data with both disk-level and VM-level throughput/IOPS limits and workload demand

Storage performance can be capped by disk provisioning and VM aggregate limits, so correlate guest latency/queue with platform throughput/IOPS and demand. Low CPU does not rule out I/O pressure; a disk SKU alone omits VM caps; caching changes need workload and cache-path evidence and do not automatically remove all limits.
