Explanation

B is correct because CAPWAP (Control and Provisioning of Wireless Access Points) uses UDP, not TCP, as its transport mechanism. It operates over UDP port 5246 for the control channel and UDP port 5247 for the data channel. The statement in option A is therefore false - while CAPWAP is indeed an application layer protocol used between a WAC and FIT APs, the claim about TCP-based transmission is incorrect. UDP was chosen intentionally for CAPWAP because it offers lower overhead and latency, and CAPWAP implements its own reliability mechanisms at the application layer where needed rather than relying on TCP.

Memory tip: Remember "CAPWAP = UDP" by associating the "W" in CAPWAP with "Wireless" - wireless protocols favor the speed of UDP over the overhead of TCP, and CAPWAP handles its own reliability independently.
