Answer #1

D is correct. The three-way handshake begins with a synchronization packet (SYN), which is then acknowledged (SYN/ACK). The last step is an acknowledgment of the sequence numbers (ACK).

A, B, and C are incorrect. The steps are out of order.

    Hosts A and B are communicating over a TCP connection, and Host B has already received from A all bytes up to and including byte 1029. Suppose Host A then sends three segments to Host B back-to-back. The first, second and third segments contain 1200, 150 and 80 bytes of data respectively. In the first segment, the sequence number is 1060, the source port number is 8080, and the destination port number is 80. Host B sends an acknowledgment whenever...
