Why configure a trunk port on the switch port that connects to a WLC distribution port?

Configuring a trunk port on the switch port connected to a Wireless LAN Controller (WLC) distribution port is essential to allow multiple VLANs to be used in the data path. Access Points (APs) associated with the WLC often serve clients from different VLANs (e.g., corporate, guest, IoT). The WLC needs to be able to forward traffic for all these VLANs to and from the wired network. A trunk port, using protocols like 802.1Q, tags frames with their respective VLAN IDs, enabling the WLC to differentiate and route traffic correctly for each VLAN. The other options are incorrect: Redundancy for out-of-band management is not the primary purpose of a trunk port in this context. While a trunk port can carry management VLANs, its main role is for client data. Eliminating redundancy is contrary to network design best practices.
