200-301 Question 124
Single answerA network engineer is troubleshooting a wireless network experiencing intermittent connectivity issues. Upon investigation, they find that multiple devices are operating on the same channel, causing interference. Which wireless principle is being violated in this scenario?
- A
Channel overlap
- B
Signal-to-noise ratio
- C
SSID broadcast
- D
WPA2 encryption
Show answer and explanation
Correct answer: A
Explanation
The scenario describes a situation where multiple devices are using the same wireless channel, leading to interference. This is a violation of the principle of avoiding channel overlap. Proper channel planning, especially in environments with multiple access points, is essential to minimize interference and ensure reliable wireless performance.
- A. Correct.
Channel overlap occurs when multiple wireless networks or devices use the same channel, resulting in interference and degraded performance, which matches the described scenario.
- B. Incorrect.
Signal-to-noise ratio refers to the strength of the wireless signal compared to background noise. While important, it is not directly related to the channel interference described here.
- C. Incorrect.
SSID broadcast is the act of making a wireless network's name visible to devices. It has no impact on the issue of devices operating on the same channel.
- D. Incorrect.
WPA2 encryption is a security protocol used to protect wireless networks. It is unrelated to channel interference or connectivity issues caused by overlapping channels.
