Show answer & explanation
Correct answer: A
In IPv4, packet fragmentation is handled when a packet is too large for a network’s Maximum Transmission Unit (MTU).
The IPv4 header includes specific fields for this purpose:
More Fragments (MF) flag → indicates whether more fragments follow
Fragment Offset field → shows the position of each fragment in the original packet
These fields allow proper fragmentation at the sender side and reassembly at the receiver side.
