An engineer needs to configure an access point to forward all client traffic through a wireless controller. Which mode must be enabled to accomplish this task?

In Cisco wireless architectures, a lightweight access point configured in local mode tunnels all client traffic (data and control) from the AP to the centralized Wireless LAN Controller (WLC) for processing, authentication, and forwarding. This is the default mode for most lightweight APs when joined to a controller.

Monitor mode is used for scanning channels to detect rogue access points, intrusions, and interference, but it does not serve clients or forward their traffic.

Autonomous mode means the access point functions independently without a controller, handling all client authentication and traffic forwarding locally, directly contradicting the requirement to forward traffic through a wireless controller.

Rogue detector mode is a specialized monitoring mode where an AP dedicates itself to detecting unauthorized (rogue) access points and does not allow client associations or forward client traffic.
