Exam 200-301 topic 1 question 41 discussion

C. 1,6,11 is correct. Question poorly worded, collisions happen in a wired network, congestion happens in a wireless network.

C is correct. 1,6,11 don't overlap.

In the 2.4 GHz frequency band, the three channels that are commonly used to limit collisions when using direct sequence spread spectrum (DSSS) are channels 1, 6, and 11. These channels are spaced far enough apart in the spectrum to minimize the likelihood of interference between devices operating on different channels. DSSS is a spread spectrum technique that is used to reduce the impact of interference on wireless communication. It involves spreading the data signal over a wide frequency band by modulating the data with a high-frequency code, or "chipping" code. This chipping code is used to spread the signal over a wide frequency range, making it less vulnerable to interference and more resistant to noise. By using DSSS and selecting channels 1, 6, and 11, it is possible to limit collisions and improve the performance of the wireless network. It's important to note, however, that other factors, such as the number of devices on the network, the type of devices, and the distance between devices, can also impact the performance of the network and may require additional strategies to optimize network performance.

C is the one.

1+6+11 :) ♥ C IS CORRECT

2.4 Ghz uses 5-hop metrics for limiting collisions

1,6,11 is correct

Depends on the region/country where you are residing but most commonly it is 1, 6 and 11.
