Question 602 of 750
Troubleshooting 'Out of Application Memory' on macOS for CompTIA A+ Core 2
This 220-1202 practice question tests your understanding of macos features and tools. 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 reports that their MacBook Pro running macOS Monterey frequently displays a message saying 'Your system has run out of application memory.' They have 16 GB of RAM and are only using Safari and Mail. Which macOS tool should you use to investigate the cause?
Quick Answer
The answer is Activity Monitor, because the “out of application memory macOS” error signals high memory pressure, and Activity Monitor’s Memory tab provides a live graphical view of memory pressure alongside per-process usage. This tool allows you to pinpoint whether a specific application, such as Safari or Mail, is leaking memory or if the system is simply overtaxed. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your ability to differentiate between diagnostic utilities—a common trap is choosing System Information, which shows static hardware specs but no real-time memory data. Remember that memory pressure, not just total RAM used, is the key metric; a green pressure graph means healthy, while red indicates a problem. For a quick memory tip: think “Activity for live action, System for static facts.”
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
✓
Activity Monitor
Activity Monitor is the correct tool because it provides real-time, graphical monitoring of memory pressure, process-specific memory usage, and the 'Memory' tab's 'Memory Pressure' graph directly indicates whether the system is under memory strain. Since the user has 16 GB of RAM and is only using Safari and Mail, the 'out of application memory' error typically indicates a memory leak or excessive memory consumption by a specific process, which Activity Monitor can pinpoint by sorting processes by memory usage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The A+ exam often tests the distinction between diagnostic tools by making candidates confuse a static information tool (System Information) or a log viewer (Console) with a real-time performance monitor (Activity Monitor), especially when the symptom is a dynamic resource exhaustion issue.
Trap categories for this question
Command / output trap
vm_stat shows virtual memory statistics but is less user-friendly than Activity Monitor for a technician.
Detailed technical explanation
How to think about this question
The 'out of application memory' error occurs when the system's memory pressure is high, forcing the kernel to compress memory or swap to disk, which degrades performance. Activity Monitor's 'Memory Pressure' graph uses a color-coded system (green, yellow, red) based on the 'memory pressure' metric, which is derived from the 'vm_page_free_count', 'vm_page_active_count', and 'vm_page_wired_count' kernel variables, giving a more nuanced view than simple free RAM. In real-world scenarios, a single Safari tab with a JavaScript-heavy site can leak hundreds of megabytes, and Activity Monitor's 'Memory' column sorted descending immediately reveals the culprit.
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.
TExam Day Tips
- 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.
