The answer is to increase the display scaling percentage in the operating system settings. This works because scaling enlarges text and UI elements while keeping the monitor at its native 4K resolution, which preserves the sharp, crisp image quality that high-resolution displays are designed for. Lowering the resolution would make text larger but would introduce blurriness, as the monitor would no longer be using its ideal pixel grid. On the CompTIA A+ Core 1 220-1201 exam, this question tests your understanding of the difference between resolution and scaling—a common trap is choosing “reduce resolution” because it seems like a quick fix. Remember that scaling is a software-level adjustment that maintains pixel-perfect clarity, whereas resolution changes are hardware-level and degrade quality. A useful memory tip: “Scale up, don’t drop down”—keep the native resolution high and let the OS scale the interface for readability.
220-1101 Display Devices Practice Question
This 220-1201 practice question tests your understanding of display devices. 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 complains that text on their new 27-inch 4K monitor appears very small and hard to read. The display is set to its native resolution. What is the most effective way to make text readable without sacrificing image quality?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Increase the display scaling percentage in OS settings
Adjusting the display scaling in the operating system increases the size of text and UI elements while keeping the native resolution, preserving sharpness. Lowering resolution would make text larger but blurry.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Reduce the screen resolution to 1920x1080
Why it's wrong here
Lowering resolution makes text larger but causes blurriness because it's not the native resolution.
✓
Increase the display scaling percentage in OS settings
Why this is correct
Scaling enlarges text and UI while keeping native resolution, maintaining clarity.
Related concept
Static NAT maps one inside address to one outside address.
✗
Replace the monitor with a lower-resolution model
Why it's wrong here
This is unnecessary and costly; scaling solves the problem without replacing hardware.
✗
Adjust the monitor's physical sharpness setting
Why it's wrong here
Sharpness controls edge contrast, not text size, and won't make text larger.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
