Question 62

A new company recently moved into an empty office space Within days, users in the next office began noticing increased latency and packet drops with their Wi-Fi-connected devices. Which of the following is the MOST likely reason for this issue?

Options:

Channel overlap

Distance from the AP

Bandwidth latency

RF attenuation

Network congestion

Discussion

Answer:

Explanation:

Explanation:

Channel overlap occurs when two or more wireless access points (APs) use the same or adjacent frequency channels within the same area12. This can cause interference and degradation of the wireless signal quality, resulting in increased latency and packet drops for the Wi-Fi-connected devices12.
Channel overlap is one of the most common causes of Wi-Fi performance issues, especially in densely populated areas where there are many wireless networks operating in the same spectrum12. The 2.4 GHz band, which is widely used by Wi-Fi devices, has only three non-overlapping channels (1, 6, and 11) in most regions, making it more prone to channel overlap than the 5 GHz band, which has more non-overlapping channels available12.
To fix channel overlap, network administrators should perform a site survey to identify the existing wireless networks and their channel usage, and then configure their APs to use the least congested or non-overlapping channels12. Alternatively, they can use APs that support automatic channel selection, which can dynamically adjust the channel based on the network conditions12.
The other options are not the most likely reasons for the issue. Distance from the AP can affect the signal strength and quality, but it does not explain why the issue occurred only after the new company moved in3. Bandwidth latency is a measure of the delay in data transmission, which can be affected by various factors such as network congestion, routing, or quality of service, but it is not a cause of the issue itself4. RF attenuation is the loss of signal power due to distance, obstacles, or interference, which can also affect the Wi-Fi performance, but it is not specific to the scenario described in the question5. Network congestion is the state of high demand and low availability of network resources, which can cause latency and packet loss, but it is not necessarily related to channel overlap6. References:

Fatima

Hey I passed my exam. The world needs to know about it. I have never seen real exam questions on any other exam preparation resource like I saw on Cramkey Dumps.

Niamh May 4, 2026

That's true. Cramkey Dumps are simply the best when it comes to preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Billy

It was like deja vu! I was confident going into the exam because I had already seen those questions before.

Vincent May 19, 2026

Definitely. And the best part is, I passed! I feel like all that hard work and preparation paid off. Cramkey is the best resource for all students!!!

Ilyas

Definitely. I felt much more confident and prepared because of the Cramkey Dumps. I was able to answer most of the questions with ease and I think that helped me to score well on the exam.

Saoirse May 12, 2026

That's amazing. I'm glad you found something that worked for you. Maybe I should try them out for my next exam.

Joey

I highly recommend Cramkey Dumps to anyone preparing for the certification exam. They have all the key information you need and the questions are very similar to what you'll see on the actual exam.

Dexter May 22, 2026

Agreed. It's definitely worth checking out if you're looking for a comprehensive and reliable study resource.
