An IP packet arrives at the final destination with the M flag set as 1. What can you say about the packet?

a. The packet has not been fragmented.

b. The packet has been fragmented.

c. The packet has been fragmented, and this is not the last fragment.

d. The packet data was truncated on its way.

Answer 1

Answer:

b,c

Explanation:

if d=0 then the packet is not fragmented.

if m=1 the the packet id definately fragmented. and alsoit concludes that it is not a last packet.

if is a last packet then it should be m=0;

Answer 2

Answer:- This question has two answers. One is the option (b) and other is the option (c)

(b) The packet has been fragmented.

(c) The packet has been fragmented, and this is not the last fragment.

This is because if d = 0, then the packet is not fragmented at all.

And if m = 1 then the packet id definitely will be fragmented, and it also will conclude that it is not the last packet which is fragmented.

And if it is the last fragmented packet, then here m should be 0, i.e., m = 0.

An IP fragmentation is an internet protocol to break packets into small pieces.

The IP fragment breaks the packet in smaller pieces, so that the packets pass through the link of smaller transmission unit than that of the original packet size given.

The IP fragmentation can cause excessive retransmissions when fragments encounter packet loss and reliable protocols.

TCP must retransmit all the fragments in order to recover from the loss of a single fragment.
