There aren't two of them as he said one is a symlink, the symlink in 
/usr/sbin points to the arping in /sbin. It is essentially a shortcut, 
like a desktop short cut that starts for example firefox. Its not 
actually the program but a pointer to the file you want to execute. As 
to why there is a symlink which seems to be your question, because some 
other program or programs are coded to expect arping to be in /usr/sbin 
rather than sbin so the symlink was created to satisfy this dependency 
or the other programs would fail to find it and as a result fail to 
execute as expected.
