Question 705 of 750
Windows OS TroubleshootingmediumMultiple ChoiceObjective-mapped

Quick Answer

The answer is Avg. Disk Queue Length. This counter is the first to check because it directly measures how many read/write requests are waiting for the disk to become free; a sustained value above 2 indicates the disk is overwhelmed and cannot keep up with demand, which is exactly what happens when a system with only 8 GB of RAM and a mechanical hard drive starts paging heavily to the page file during multitasking, causing those 5–10 second freezes. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of how limited RAM forces the OS to use the disk as virtual memory, and the trap is to focus on CPU or memory counters instead of recognizing that the disk queue reveals the true bottleneck. Remember the “Rule of Two”: if Avg. Disk Queue Length stays above 2 for any length of time, the disk is the bottleneck.

This 220-1202 practice question tests your understanding of windows os troubleshooting. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.

A user on Windows 11 reports that their computer frequently freezes for 5–10 seconds at a time, especially when opening multiple browser tabs. The system has 8 GB of RAM and a mechanical hard drive. Which performance monitor counter should you check first to confirm the likely bottleneck?

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

Avg. Disk Queue Length

Frequent freezing when multitasking on a system with a mechanical hard drive and limited RAM often points to excessive disk usage due to paging. The 'Avg. Disk Queue Length' counter in Performance Monitor indicates how many requests are waiting for the disk; a sustained value over 2 suggests the disk is the bottleneck, likely from swapping memory to the page file.

Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • % Processor Time

    Why it's wrong here

    While high CPU usage can cause slowdowns, it typically results in sluggishness rather than the short, periodic freezes described. The scenario points more toward disk I/O than CPU.

  • Available Mbytes

    Why it's wrong here

    Available memory is a useful metric, but the freezes are more likely caused by the disk struggling to handle paging when memory is low. Checking disk counters first is more direct.

  • Avg. Disk Queue Length

    Why this is correct

    A high average disk queue length indicates that the disk is overwhelmed with requests, which is a classic symptom of excessive paging on a system with insufficient RAM and a slow HDD. This is the best counter to confirm the bottleneck.

    Clue confirmation

    The clue word "first" in the question point toward this answer.

    Related concept

    Read the scenario before looking for a memorised answer.

  • Pages/sec

    Why it's wrong here

    Pages/sec measures the rate of hard page faults (memory swapping to disk). While related, the Avg. Disk Queue Length more directly shows the impact on disk performance, which causes the freezes.

Common exam traps

Common exam trap: answer the scenario, not the keyword

Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.

Trap categories for this question

  • Command / output trap

    Pages/sec measures the rate of hard page faults (memory swapping to disk). While related, the Avg. Disk Queue Length more directly shows the impact on disk performance, which causes the freezes.

  • Scenario analysis trap

    While high CPU usage can cause slowdowns, it typically results in sluggishness rather than the short, periodic freezes described. The scenario points more toward disk I/O than CPU.

Detailed technical explanation

How to think about this question

This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Read the scenario before looking for a memorised answer.
  • Find the constraint that changes the correct option.
  • Eliminate answers that are true in general but not in this case.
  • Use explanations to understand the rule behind the answer.

TExam Day Tips

  • Underline the problem statement mentally.
  • Watch for words such as best, first, most likely and least administrative effort.
  • Review why wrong options are wrong, not only why the correct option is correct.

Key takeaway

Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Real-world example

How this comes up in practice

A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
