Explanation / Answer

The LLC and pad fields must be between 46 and 1500 bytes in length.If the data is not a minimum of 43 bytes, the field is padded withundefined characters or groups of bytes. The pad is automaticallystripped off by the LAN interface card, so by this being as it is,your answer is #4! :) That wasjust one example of the pad fields and its applications! I hopethis makes sense and helps!
