20+ practice questions focused on Wireless Networking Technologies — one of the most tested topics on the CompTIA A+ Core 1 220-1201 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Wireless Networking Technologies PracticeA company deploys a new 802.11ac access point in a warehouse. After installation, workers report that their handheld scanners frequently disconnect when moving between aisles. The AP is mounted on a high ceiling. Which configuration change would most likely improve connectivity?
Explanation: 802.11ac operates on 5 GHz, which has shorter range and poorer penetration through obstacles like metal racks. Enabling 2.4 GHz on the AP provides better range and obstacle penetration for mobile devices.
During a site survey for a new branch office, you measure signal strength in the conference room and find it is -85 dBm. The client devices require at least -67 dBm for reliable video conferencing. Which action is most appropriate?
Explanation: A signal of -85 dBm is very weak (near noise floor). The best solution is to add an access point closer to the conference room to boost signal strength to the required level.
A small office uses a legacy 2.4 GHz wireless b/g router. Employees report frequent disconnects and slow speeds, especially when the microwave is used in the break room. Which change would most directly reduce interference in this scenario?
Explanation: The 2.4 GHz band is shared by many devices, including microwaves, which cause interference. Switching to the 5 GHz band avoids this because microwaves operate at 2.4 GHz. This is a common real-world troubleshooting step for wireless connectivity issues.
A technician is deploying a point-to-point wireless bridge between two buildings 500 meters apart. The link must support at least 1 Gbps throughput. Both buildings have clear line of sight. Which antenna type and frequency combination is most appropriate?
Explanation: For long-distance point-to-point links, directional antennas (like parabolic or grid) on the 5 GHz band provide high gain and focused signal, achieving high throughput over distance. 2.4 GHz has more interference and lower capacity.
A user's laptop connects to the office Wi-Fi but cannot access the internet. Other devices on the same network work fine. The laptop's IP address is 169.254.25.14. What is the most likely cause?
Explanation: A 169.254.x.x address indicates the device failed to obtain an IP from a DHCP server. This is an Automatic Private IP Addressing (APIPA) address, meaning the laptop cannot reach the DHCP server.

Start with 10 questions to gauge your current understanding of Wireless Networking Technologies. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Wireless Networking Technologies questions on the 220-1201 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Wireless Networking Technologies is tested as part of the CompTIA A+ Core 1 220-1201 blueprint. Practicing with targeted Wireless Networking Technologies questions ensures you can handle any format or difficulty that appears.
