Three access points are used within a facility. One access point is on channel 11 and the other two are on channel 1. The two access points using channel 1 are on either side of the access point using channel 11 and sufficiently apart so that they do not interfere with each other when they transmit frames. Assuming no additional APs are in the vicinity, is CCI (also called CCC) still a possibility in this network and why?

1. A. No, because the APs are far enough apart that no CCI will occur
2. B. Yes, because the client devices connected to one of the channel 1 APs may transmit frames that reach the other channel 1 AP as well as reaching clients connected to both channel 1 APs — đáp án hiện tại
3. C. Yes, because channel 11 loops around and causes CCI with channel 1
4. D. No, because CCI only occurs in the 5 GHz and 6 GHz frequency bands
