200-301 Question 128
Select 3You are tasked with designing a Wi-Fi network in an office environment. To minimize interference, you need to configure multiple access points on the 2.4 GHz band using nonoverlapping channels. Which channels should you select to ensure minimal overlap and interference?
- A
Channel 1
- B
Channel 3
- C
Channel 6
- D
Channel 8
- E
Channel 11
Show answer and explanation
Correct answers: A, C, E
Explanation
In the 2.4 GHz frequency band, only channels 1, 6, and 11 are considered nonoverlapping. These channels are spaced far enough apart to avoid interference with one another, making them ideal for use in environments with multiple access points.
- A. Correct.
Channel 1 is a nonoverlapping channel in the 2.4 GHz band, commonly used in Wi-Fi networks to minimize interference.
- B. Incorrect.
Channel 3 is not a nonoverlapping channel. Using it may result in interference with adjacent channels like 1 and 6.
- C. Correct.
Channel 6 is a nonoverlapping channel in the 2.4 GHz band, commonly used to avoid interference.
- D. Incorrect.
Channel 8 is not a nonoverlapping channel. It overlaps with channels like 6 and 11, which can cause interference.
- E. Correct.
Channel 11 is a nonoverlapping channel in the 2.4 GHz band, commonly used to minimize interference.
