200-301 Question 126
Select 3You are configuring a wireless network in a 2.4 GHz frequency band for a small office. To avoid interference and ensure optimal performance, which nonoverlapping Wi-Fi channels should you select?
- A
1
- B
6
- C
9
- D
11
- E
3
- F
8
Show answer and explanation
Correct answers: A, B, D
Explanation
In the 2.4 GHz frequency band, the nonoverlapping channels are 1, 6, and 11. These channels are spaced far enough apart to minimize interference between each other, which is critical for optimizing wireless network performance. Using any other channel, such as 3, 8, or 9, may result in channel overlap and increased interference, leading to degraded network performance.
- A. Correct.
Channel 1 is a nonoverlapping channel in the 2.4 GHz frequency band, making it ideal for reducing interference.
- B. Correct.
Channel 6 is a nonoverlapping channel in the 2.4 GHz frequency band, commonly used to avoid interference.
- C. Incorrect.
Channel 9 is not a nonoverlapping channel and may cause interference with adjacent channels.
- D. Correct.
Channel 11 is a nonoverlapping channel in the 2.4 GHz frequency band, ensuring minimal interference.
- E. Incorrect.
Channel 3 is not a nonoverlapping channel and could overlap with other commonly used channels, causing interference.
- F. Incorrect.
Channel 8 is not a nonoverlapping channel and may cause interference with adjacent channels.
