CWNA: Certified Wireless Network Administrator v107 — Question 3

You are attempting to locate the cause of a performance problem in two WLAN cells in a mostly overlapping coverage area. You note that one AP is on channel 1 and the other is on channel 2. When you document your findings, what term do you use to describe the problem in this configuration?

Answer options

• A. Bluetooth interference
• B. Non-Wi-Fi interference
• C. CCI
• D. ACI

Correct answer: C

Explanation

The correct term for the issue in this configuration is CCI, which stands for Co-Channel Interference. This occurs when two or more APs are using adjacent channels in overlapping areas, leading to interference. Options A and B refer to other types of interference that are not specific to the channel overlap issue, while D, ACI (Adjacent Channel Interference), pertains to interference from APs on non-adjacent channels.
