- A
The tablet's Bluetooth adapter is defective.
Why wrong: A defective adapter would likely cause constant failure, not intermittent disconnections tied to typing posture.
- B
The keyboard's battery is low.
Why wrong: Low battery could cause disconnections, but the scenario describes a specific pattern related to typing, not a general power issue.
- C
The user's body is blocking the Bluetooth signal when typing.
The human body can absorb Bluetooth signals, and when the user positions themselves between the keyboard and tablet, the signal is weakened, causing intermittent drops.
- D
There is interference from a nearby Wi-Fi network.
Why wrong: Wi-Fi interference is possible, but the scenario states no other Bluetooth devices are nearby, and the problem is tied to typing, not environmental interference.
Quick Answer
The answer is that the user’s body is blocking the Bluetooth signal when typing. This occurs because Bluetooth operates in the 2.4 GHz frequency range, which is easily absorbed or reflected by dense materials like water—and the human body is roughly 60% water. Even at distances under a meter, placing a hand, torso, or leg directly between the keyboard and the tablet can create enough signal attenuation to cause intermittent disconnection. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding that Bluetooth is not just about range but also about line-of-sight and physical obstructions; a common trap is assuming interference from other devices or low battery, but here no other Bluetooth devices are nearby and the distance is short. A helpful memory tip is “Body Blocks Bluetooth”—if a user reports dropouts while typing on a laptop or tablet, think of the body as a signal sponge between the two devices.
220-1201 Mobile Device Connection Methods Practice Question
This 220-1201 practice question tests your understanding of mobile device connection methods. 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 customer reports that their Bluetooth keyboard intermittently disconnects from their tablet while typing. The tablet and keyboard are less than a meter apart, and no other Bluetooth devices are nearby. Which of the following is the most likely cause of the disconnection?

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
The user's body is blocking the Bluetooth signal when typing.
Bluetooth connections can be disrupted by physical obstructions, even at short distances. The human body, especially when positioned between the keyboard and tablet, can absorb or block the radio signal. This scenario tests understanding that line-of-sight and physical barriers affect Bluetooth range and stability.
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.
- ✗
The tablet's Bluetooth adapter is defective.
Why it's wrong here
A defective adapter would likely cause constant failure, not intermittent disconnections tied to typing posture.
- ✗
The keyboard's battery is low.
Why it's wrong here
Low battery could cause disconnections, but the scenario describes a specific pattern related to typing, not a general power issue.
- ✓
The user's body is blocking the Bluetooth signal when typing.
Why this is correct
The human body can absorb Bluetooth signals, and when the user positions themselves between the keyboard and tablet, the signal is weakened, causing intermittent drops.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

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 220-1201 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.
