mincir should be 64k because question clearly says that when the interface
receives BECN's it will shape it down to 64k. I think it should be minCIR=
64k, CIR=256k, BC = 8000 and BE = 24000
Not very sure if BE need to be configured here.

During congestion your provider will mark
any traffic in excess of 64kbps as discard eligible.
This makes cir 64k, the point in which you have gone over your committed
rate thus DE. Sadiq and Rich are right on this. AR = 256k which was given so
you could calculate be.

I agree with John.......minCIR= 64k, CIR=256k and NO Be.
