Correct answer: The access point has the ability to link to any switch in the network, assuming connectivity to the WLC.
Why this is the answer
A local-mode access point (AP) uses the Control and Provisioning of Wireless Access Points (CAPWAP) protocol to communicate with its Wireless LAN Controller (WLC). CAPWAP encapsulates both control and data plane traffic. This allows the AP to connect to any switch in the network, as long as it has IP reachability to the WLC. The AP does not need to be on the same switch or directly connected to the WLC. The AP must be connected to the wired network to function; not connecting it would prevent communication. A loop would only occur with improper spanning tree protocol (STP) configuration, not simply by connecting an AP.
