Which AP mode supports various wireless clients after connecting to a WLC?

The local mode is the correct answer because it is specifically designed to facilitate the connection of various wireless clients to a Wireless LAN Controller (WLC). In local mode, the access point (AP) acts as a centralized point that allows clients to connect to the network while still providing various features such as security, traffic management, and QoS. This mode allows the AP to perform tasks like encryption and decryption, making it suitable for handling client communications effectively.

In local mode, the AP also manages the data traffic and supports features like Voice over IP (VoIP) and guest access. This is vital for environments where many different devices connect to the network simultaneously. Hence, the ability to serve multiple wireless clients is a key aspect of local mode's functionality.
