Which access point operating mode depends on a centralized controller for management, roaming, and SSID configuration?

Lightweight mode (also known as controller-based or thin access point mode) relies on a Wireless LAN Controller (WLC) for all configuration, management, and control functions, including SSID broadcasting, security, and client roaming. This centralizes management for large-scale deployments. Autonomous mode access points are self-contained and manage their own configurations and client associations without a WLC. Bridge mode connects two wired networks wirelessly. Repeater mode extends wireless coverage by retransmitting signals from another access point.
