- A
5 GHz frequency band
Why wrong: 5 GHz has shorter range and is worse at penetrating walls, so it would not improve connectivity to a detached garage.
- B
Wireless mesh network
Mesh networks use multiple access points to blanket an area with seamless coverage, perfect for extending Wi-Fi to a separate building.
- C
Powerline networking adapters
Why wrong: Powerline uses electrical wiring, not wireless, and may not work reliably across separate buildings on different electrical panels.
- D
802.11ac standard
Why wrong: 802.11ac operates mainly on 5 GHz and offers high speed but not the extended range needed for this scenario.

220-1201 Wireless Networking Technologies Practice Question
This 220-1201 practice question tests your understanding of wireless networking technologies. 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 customer reports that their laptop frequently disconnects from the Wi-Fi in their home office, but works fine in other rooms. The office is located in a detached garage, and the wireless router is in the main house. Which wireless networking technology would best solve this issue without running cables?
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
✓
Wireless mesh network
A wireless mesh network is the best solution because it extends Wi-Fi coverage to the detached garage without running cables. Mesh nodes communicate wirelessly with each other, creating a seamless network that overcomes the range and obstruction issues caused by the distance and building materials between the main house and garage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
5 GHz frequency band
Why it's wrong here
5 GHz has shorter range and is worse at penetrating walls, so it would not improve connectivity to a detached garage.
- ✓
Wireless mesh network
Why this is correct
Mesh networks use multiple access points to blanket an area with seamless coverage, perfect for extending Wi-Fi to a separate building.

- ✗
802.11ac standard
Why it's wrong here
802.11ac operates mainly on 5 GHz and offers high speed but not the extended range needed for this scenario.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The CompTIA A+ exam often tests the misconception that upgrading to a newer standard (like 802.11ac) or switching to 5 GHz alone will fix range issues, when in fact these technologies are more susceptible to attenuation and require a strong signal to deliver their benefits.
Trap categories for this question
Scenario analysis trap
802.11ac operates mainly on 5 GHz and offers high speed but not the extended range needed for this scenario.
Detailed technical explanation
How to think about this question
Wireless mesh networks use multiple access points (nodes) that communicate via dedicated backhaul channels (often on a separate radio or frequency) to relay traffic, effectively creating a single extended SSID. This allows clients to roam between nodes without re-authentication, and the mesh can dynamically route around interference or node failure. In a real-world scenario, placing one mesh node in the main house and another in the garage, with line-of-sight or minimal obstruction between them, can provide reliable coverage even over 50-100 feet.
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.
