What is the maximum size of data that the application layer can pass on to the TCP layer below?
(A) Any size
(B) 216 bytes – size of TCP header
(C) 216 bytes
(D) 1500 bytes
Explanation: The default TCP Maximum Segment Size is 536. Where a host wishes to set the maximum segment size to a value other than the default, the maximum segment size is specified as a TCP option, initially in the TCP SYN packet during the TCP handshake. Because the maximum segment size parameter is controlled by a TCP option, a host can change the value in any later segment.
