In a centralized Cisco wireless network deployment using Split-MAC architecture, operational tasks are divided between Lightweight Access Points (LAPs) and the Wireless LAN Controller (WLC). Which two functions are performed by the Wireless LAN Controller rather than the Lightweight Access Points? (Select two.)
- Executing Radio Resource Management (RRM) to dynamically adjust RF channels and power levels across access pointsAnswer
- Aggregating wireless client authentication traffic and managing integration with central RADIUS serversAnswer
- CTerminating Layer 2 broadcast domains to eliminate the need for Layer 3 routing devices
- DOperating directly on top of a client host operating system as a Type 2 hypervisor to process frame transmission
Answer
The Wireless LAN Controller handles Radio Resource Management (RRM) for dynamic channel/power optimization and processes centralized client authentication requests.
In a centralized Split-MAC architecture, the Wireless LAN Controller performs high-level management and control-plane tasks. This includes Radio Resource Management (RRM) to continuously calculate optimal channel assignments and transmit power for all connected access points, as well as handling centralized client authentication and external RADIUS server communications.
