- A
A USB-C hub with Bluetooth functionality to extend range.
Why wrong: A USB-C hub with Bluetooth can help, but it is not strictly necessary if the tablet has built-in Bluetooth and the devices are within typical range.
- B
A Bluetooth adapter plugged into the tablet's charging port.
Why wrong: Most tablets already have Bluetooth; an external adapter is redundant and may not improve range significantly.
- C
A Bluetooth extender or repeater to boost signal strength.
This is correct; a Bluetooth extender can increase the effective range, ensuring reliable connection from across the room.
- D
A wireless dongle that connects both keyboard and mouse via a single receiver.
Why wrong: This would work for non-Bluetooth devices, but the customer specifically wants Bluetooth devices, so a dongle is unnecessary.
Quick Answer
The correct recommendation is a Bluetooth extender or repeater to boost signal strength, as this directly addresses the need for reliable long-range connectivity between the tablet and the Bluetooth keyboard and mouse. While most tablets already have built-in Bluetooth, the standard Class 2 Bluetooth radio typically has a range of only about 10 meters (33 feet) and can be weakened by walls or interference, so a Bluetooth extender amplifies the signal to ensure stable performance from across a large room. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of wireless range limitations and the difference between a Bluetooth adapter (which adds Bluetooth to a device lacking it) and an extender (which boosts an existing signal). A common trap is confusing “adapter” with “extender,” so remember: if the tablet already has Bluetooth, you only need an extender for range, not an adapter. Memory tip: “Extend the range, don’t adapt the change.”
220-1201 Mobile Device Accessories Practice Question
This 220-1201 practice question tests your understanding of mobile device accessories.

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
A Bluetooth extender or repeater to boost signal strength.
A Bluetooth adapter is not needed if the tablet already has Bluetooth, but a Bluetooth extender or a USB hub with Bluetooth can improve range. However, the most straightforward answer is that a Bluetooth adapter (if the tablet lacks built-in Bluetooth) is essential, but since most tablets have it, a simple Bluetooth keyboard and mouse set will work. The correct answer here is that a Bluetooth adapter is not required; the tablet's built-in Bluetooth is sufficient, but for range, a Bluetooth extender can help.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
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.
