| Question 6 |
Host A (on TCP/1Pv4 Networks) sends an IP Datagram D to host B (also on TCP/IPv4 network).
Assume that no error occurred during transmission of D, when D reaches B. Which of following header field may differ from that of original datagram D ?
(A) TTL
(B) Checksum
(C) Fragment offset
(D) Source IP
(E) Destination IP
Choose the correct answer from the options given below :

Question 6 Explanation:
The source IP address is set by Host A and will not change during transmission unless network address translation (NAT) or some form of IP address rewriting occurs, but this is not stated in the problem. The source IP will not differ.
The destination IP address is part of the original datagram and does not change during transmission. It will stay the same throughout the journey from Host A to Host B.
The destination IP address is part of the original datagram and does not change during transmission. It will stay the same throughout the journey from Host A to Host B.
Correct Answer: B
