Multiple choice

Which is a Valid first IP fragment with an MTU of 1500?

  1. MF=1 Offset = 185 Data = 1480

  2. MF=1 Offset = 0 Data = 1480

  3. MF=1 Offset = 0 Data = 1470

  4. MF=0 Offset = 0 Data = 1470

B Correct answer
Explanation

The first fragment must have an offset of 0. Since the MTU is 1500 and the header is 20 bytes, the maximum payload is 1480 bytes. Option B correctly shows offset 0, MF=1 (more fragments follow), and 1480 bytes of data.
