The answer is to upgrade the RAM to at least 8GB. This directly addresses the root cause because the system is experiencing page file thrashing: with only 4GB of RAM and physical memory usage at 95%, Windows is constantly swapping data between the slow HDD and RAM, which explains the solid hard drive activity light and unresponsive applications. On the CompTIA ITF+ FC0-U61 exam, this scenario tests your understanding of virtual memory and the performance impact of insufficient RAM versus simply closing programs or cleaning the disk. A common trap is to suggest freeing up hard drive space, but the 200GB free shows storage is not the bottleneck—the issue is high memory usage forcing heavy page file activity. Remember the thrashing rule: when the HDD light is solid and RAM is maxed, adding RAM stops the swap.
FC0-U61 IT Concepts and Terminology Practice Question
This FC0-U61 practice question tests your understanding of it concepts and terminology. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 small accounting office uses three desktop computers running Windows 10. One computer has become extremely slow over the past week. The user reports that the computer takes a long time to start up and applications are unresponsive. The technician checks Task Manager and sees that physical memory usage is at 95% and the page file is heavily used. The hard drive activity light is solid. The computer has 4GB of RAM and a 1TB HDD with 200GB free. Which course of action should the technician take first to most directly address the performance issue?

Correct answer & explanation
✓
Upgrade the RAM to at least 8GB
The system has only 4GB of RAM, and physical memory usage is at 95% with heavy page file utilization. This indicates the computer is thrashing — constantly swapping data between RAM and the slow HDD, causing the solid hard drive activity light and unresponsiveness. Adding more RAM (to at least 8GB) directly reduces reliance on the page file, alleviating the bottleneck and addressing the root cause of the performance issue.
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.
✗
Increase the page file size
Why it's wrong here
Increasing page file size would use more disk space but not improve performance; the system needs more physical RAM.
✓
Upgrade the RAM to at least 8GB
Why this is correct
Upgrading RAM directly addresses the memory shortage, reducing swapping and improving overall speed.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Disable unnecessary startup programs
Why it's wrong here
Disabling startup programs might free some RAM, but the system is already at 95% usage; a few programs won't make enough difference.
✗
Run a full antivirus scan
Why it's wrong here
An antivirus scan is good practice but does not directly address the memory shortage causing the slowness.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often choose 'Increase the page file size' (Option A) thinking more virtual memory will help, but they fail to recognize that the bottleneck is the speed of the HDD, not the size of the page file, and that adding physical RAM is the only way to reduce paging activity.
Detailed technical explanation
How to think about this question
When physical memory is exhausted, Windows uses the page file (typically C:\pagefile.sys) as virtual memory, but HDD I/O is orders of magnitude slower than RAM (e.g., ~100 MB/s for HDD vs. ~20 GB/s for DDR4). The 'solid' HDD light indicates constant read/write operations as the system swaps memory pages, a condition known as disk thrashing. In a real-world scenario, even with 200GB free, a 4GB system running modern Windows 10 and accounting software (e.g., QuickBooks, Excel) will frequently exceed RAM capacity, making a RAM upgrade the only effective first step.

→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 FC0-U61 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.
