Which interface mode must be configured to connect the lightweight APs in a centralized architecture?
In a centralized wireless architecture, the access points (APs) are lightweight, which means they do not have their own control plane but rely on a wireless LAN controller (WLC) to provide the control and management functions. The WLC is responsible for configuring and managing the APs and providing the necessary connectivity to the wired network.
To connect the lightweight APs to the WLC in a centralized architecture, the WLC interfaces must be configured appropriately. The interface mode that is typically used to connect the APs is the "trunk" mode.
A trunk interface is used to carry multiple VLANs over a single physical link between two network devices, such as a switch and a WLC. In the case of APs, the trunk interface allows the APs to send and receive traffic for multiple VLANs, including the native VLAN and any VLANs assigned to specific WLANs.
The WLAN dynamic interface mode is used to dynamically assign IP addresses to wireless clients based on the SSID they connect to. It is not used to connect the APs themselves.
The access interface mode is used to connect end devices, such as computers or printers, to the network. It does not provide the necessary functionality to connect the APs to the WLC.
The management interface mode is used to manage the WLC itself, such as configuring its IP address or accessing its web interface. It is not used to connect the APs.
Therefore, the correct answer is B. trunk.
