A. 5GHz provides increased network capacity with up to 23 nonoverlapping channels. and C. Cells that overlap one another are configured to use nonoverlapping channels.
A is correct. C is correct. and E could be correct if they were specifing that the Adjacent cell is automaticly configured to a different Chanel.
Explanation When designing a Wi-Fi network and adding new coverage cells, Cisco best practices focus on: 5 GHz for capacity The 5 GHz band supports many more non-overlapping channels than 2.4 GHz. Depending on the country and DFS channels, you can have up to 23 non-overlapping 20-MHz channels, making this the preferred band for high-density deployments. This matches Answer A. Using non-overlapping channels in adjacent cells Overlapping access point coverage cells are normal and required for roaming. However, their channels must NOT overlap to prevent co-channel interference (CCI). This matches Answer C.
