QUESTION 5 A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. A sent a segment of O bytes data payload to B with FIN flag set, sequence number 1000 and ACK number 500. Later B sent a segment of O bytes data with FIN flag set, sequence number 500 and ACK number 1000. What is the state of the connection in host A before receiving the ACK from B and after receiving the ACK ? QUESTION 6 A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. A sent a segment of O bytes data payload to B with FIN flag set, sequence number 1000 and ACK number 500. Later B sent a segment of O bytes data with sequence number 500 and ACK number 1001. What is the state of the connection in host A before receiving the ACK from B and after receiving the ACK ? QUESTION 7 A Wireshark trace of TCP traffic between hosts A and B indicated the following segments. Host A sent a segment of 0 bytes data payload to host B with SYN flag set, sequence number 200 and no valid ACK number. Later B sent a segment of O bytes data with SYN and ACK flags set, sequence number 100 and ACK number 201. What is the state of the connection in host B before receiving SYN from host A and after sending SYN-ACK to host A ?
