Question

What should be the flag value to indicate the last fragment?

(a) 0

(b) 1

(c) TTl value

(d) Protocol field value

This question was addressed to me in class test.

Question is taken from IPv4 in division TCP/IP Protocol Suite of Computer Network

Answer 1

The correct choice is (a) 0

To explain I would say: The Flag field in the IP header is used to control and identify the fragments. It contains three bits: reserved, don’t fragment and more fragments. If the more fragments bit is 0, it means that the fragment is the last fragment.
