Difficulty: MediumTroubleshooting Windows Performance and Application Crashes

A Windows workstation running an enterprise database utility experiences frequent '(Not Responding)' freezes followed by sudden application crashes during heavy reporting tasks. Task Manager shows moderate CPU (25%) and Memory (40%) utilization, but overall responsiveness drops significantly during file exports. A technician suspects storage subsystem latency is causing the application timeouts and crashes. Which of the following tools and metrics should the technician inspect FIRST to isolate this storage performance bottleneck?

  1. Resource Monitor to evaluate Disk Queue Length and Average Response Time for the specific process.Answer
  2. B
    Event Viewer Application log to reconfigure the maximum log size and disk write buffering limits.
  3. C
    Elevated Command Prompt to run chkdsk /f for replacing missing application system DLL files.
  4. D
    System Applet in Control Panel to adjust processor scheduling priorities toward background services.

Answer

Resource Monitor to evaluate Disk Queue Length and Average Response Time for the specific process.
Evaluating Resource Monitor allows the technician to break down disk performance by individual process. Checking metrics such as Disk Queue Length and Average Response Time directly measures storage latency and I/O saturation, confirming if storage bottlenecks are causing application timeouts.

Step-by-Step Solution

1
Analyze the symptoms described in the scenario
CPU and Memory utilization are normal, but disk-heavy tasks cause freezes and application crashes due to suspected storage latency.
Identifying the root system component affected helps narrow down the diagnostic tool required.
2
Select the administrative tool designed for real-time process-specific disk I/O analysis
Resource Monitor displays active processes along with real-time disk response times and queue lengths.
High Disk Queue Length (consistently above 2 per disk) and elevated Average Response Time (ms) confirm disk I/O bottlenecks.
