Policing or max-reserved-bandwith?

Guys,

I have a question about how Cisco considers the maximum bandwidth
available on a line in terms of the CCIE lab.

Lets say you have a router connected to a frame relay cloud, and the
question states that you should never exceed 65% of the available
bandwidth on the line. Assume that FRTS can not be used, and that you do
not know the speed of the line.

Which of the following solutions would be the most appropriate:

A)

int serial 0/0
  max-reserved-bandwidth 65

B)

policy-map POLICE
  class class-default
    police percent 75

int serial 0/0
  max-reserved-bandwidth 100
  service-policy output POLICE

C)

policy-map POLICE
  class class-default
    police percent 75

int serial 0/0
  ! Default bandwidth
  max-reserved-bandwidth 75
  service-policy output POLICE

What do you think?

Alex
