Question

A PC is running slower than usual. Which of the following tools would BEST diagnose the possible bottleneck?

Options

  • ACHKDSK
  • BDevice Manager
  • CTask Scheduler
  • DTask Manager

Explanation

Task Manager provides real-time visibility into CPU, memory, disk, and network utilization, making it the best tool to identify performance bottlenecks on a slow PC.

Common mistakes.

  • A. CHKDSK scans for file system corruption and bad sectors; it reports disk integrity issues but does not display real-time performance metrics or identify active bottlenecks.
  • B. Device Manager shows hardware devices and their driver status and is used to diagnose driver conflicts, not runtime performance bottlenecks.
  • C. Task Scheduler manages automated tasks and their schedules and has no functionality for monitoring or diagnosing live system performance.
