- A
A privacy filter
Why wrong: Privacy filters reduce viewing angles for security but also dim the screen, which can worsen outdoor readability.
- B
An anti-glare screen protector
Anti-glare protectors diffuse reflected light, making the screen more readable in sunlight without adding bulk.
- C
A portable external monitor
Why wrong: An external monitor adds significant bulk and is not practical for field use; it also may have similar glare issues.
- D
An external battery pack
Why wrong: An external battery extends usage time but does not improve screen visibility in sunlight.

220-1201 Mobile Device Accessories Practice Question
This 220-1201 practice question tests your understanding of mobile device accessories. 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 field technician frequently uses a ruggedized tablet outdoors for data collection. They complain that the screen is hard to read in direct sunlight. Which accessory would best improve screen visibility without adding significant bulk?
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
✓
An anti-glare screen protector
An anti-glare screen protector uses a matte finish with microscopic ridges that diffuse reflected light, reducing glare and improving contrast in bright environments. This directly addresses the technician's issue of poor readability in direct sunlight without adding significant bulk to the ruggedized tablet.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA A+ often tests the distinction between privacy filters and anti-glare protectors, as candidates may confuse their functions since both are screen overlays, but privacy filters reduce viewing angles while anti-glare filters reduce reflections.
Trap categories for this question
Similar concept trap
An external monitor adds significant bulk and is not practical for field use; it also may have similar glare issues.
Detailed technical explanation
How to think about this question
Anti-glare screen protectors work by creating a diffuse reflection pattern that scatters incoming light, reducing specular reflections that wash out the display. In ruggedized tablets, which often have high-brightness displays (500–1000 nits), an anti-glare protector can further improve outdoor readability by minimizing the contrast reduction caused by ambient light. Real-world field technicians in construction or agriculture commonly pair anti-glare protectors with maximum brightness settings for optimal visibility.
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 220-1201 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.
