Host A (on TCP/IP v4 network A) sends an IP datagram D to host B (also on TCP/IP V4 network B). Assume that no error occurred during the transmission of D. When D reaches B,which of the following IP header field(s) may be different from that of the original datagram D?
(i) TTL (ii) Checksum (iii) Fragment Offset
(A) (i) only (B) (i) and (ii) only
(C) (ii) and (iii) only (D) (i), (ii) and
ANSWER : (D)
While an IP Datagram is transferring from one host to another host, TTL, Checksum and Fragmentation Offset will be changed.
