Which two functions does a WLC perform in the lightweight access-point architecture that an AP performs independently in an autonomous architecture? (Choose two.)

In a lightweight AP architecture, the WLC centrally manages and optimizes the RF environment, including dynamic channel assignment, transmission power control, and interference mitigation across all connected APs.

The WLC handles the control plane functions for client connectivity, including initial association, authentication, and facilitating seamless roaming between APs for wireless clients.

Both autonomous and lightweight APs (under WLC control) are responsible for sending and processing beacon frames to advertise the WLAN and allow clients to discover and connect.

Encrypting and decrypting wireless traffic (e.g., WPA/WPA2/WPA3) is primarily performed by the AP itself, whether autonomous or lightweight, as part of its responsibility to secure the over-the-air communication with clients.

Preventing collisions on the wireless medium (e.g., using CSMA/CA) is a fundamental MAC layer function performed by the AP itself in both autonomous and lightweight architectures.
