Which port number of the control message of the CAPWAP tunneling protocol?

Explanation
CAPWAP (Control And Provisioning of Wireless Access Points) uses UDP port 5246 for its control channel, which carries management messages between wireless LAN controllers and access points. Option D (5247) is the CAPWAP data channel port, not the control channel - a common trap since both ports belong to CAPWAP, just for different purposes. Options A (1645) and B (1646) are RADIUS ports used for authentication and accounting respectively, and have no relation to CAPWAP tunneling.
Memory tip: Think "6 before 7" - port 5246 handles control (management comes first), and port 5247 handles data (traffic flows after control is established).
