Hosts A and B are performing a TCP/IP handshake. Host B is sending a SYN-ACK to host A, what value is used for the acknowledgement number?
0 because no data has been sent
the acknowledgement number from host A incremented by 1
the sequence number from host A incremented by 1
a random 32 bit number
1 because only 1 packet has been exchanged so far
The ACK of a given packet is the sequence number from the other host incremented by the number of bytes received. The initial sequence number is a random 32 bit number and during a handshake there is no payload (0 bytes) so the SYN increments by 1 to show the packet was received.
