Everyone has some good ideas on this... and one of the replies made me
rethink my previous answer.... Look at it from the aspect of the ROUTER...
assuming that this is implemented on a router.
An interface with the address of 172.18.2.0 and a mask of 255.255.254.0
will send directed broadcasts to 172.18.3.255. Answer B is correct.
However the above router sends a RIP version 1 update (which is classless)
to router B. Router B gets the router 172.18.2.0 and no mask information.
It assumes a classful boundary. ( I know, there are other rules that affect
the advertisement and receipt of the route) Router B will then send
directed broadcasts to 172.18.255.255.
I think everyone would agree that the question is poorly worded... If I
came across the question I would still select 'C' as my answer,
172.18.255.255. My clue in the question is 'using classful assumptions'
