A. B. C. D.D.
Clustering Cisco Wireless LAN Controllers (WLCs) into an RF group enables the RRM (Radio Resource Management) algorithms to scale beyond the capabilities of a single WLC. The RRM algorithm is used to optimize the coverage and capacity of wireless networks by continuously monitoring the RF environment and adjusting the power and channel settings of the Access Points (APs) to ensure the best possible user experience.
The maximum number of WLCs and APs that can be included in an RF group depends on the WLC platform and the software release. In WLC release 8.9, the maximum number of WLCs that can be included in an RF group is 20.
The maximum number of APs that can be supported in an RF group also varies depending on the WLC platform. The following table shows the maximum number of APs that can be supported in an RF group for different WLC platforms in release 8.9:
| WLC Platform | Maximum number of APs in an RF group |
|---|---|
| 3504 | 1000 |
| 5520 | 3000 |
| 8540 | 6000 |
Therefore, the correct answer to the question is B. Up to 20 WLCs and 3000 APs can be included in an RF group in WLC release 8.9, depending on the platform.
