yu:
Do you find the correct answer?
I think Justin is right.
1 May be IOS bug ,
"Map class fast_vcs uses a peak rate of 64000 and average rate of 16000 bps
map-class frame-relay fast_vcs
frame-relay traffic-rate 16000 64000
frame-relay priority-group 2"

2 A is correct for CISCO,but not correct for RFC.But for a ccie candidate ,YOU
KNOW MY MEANING!!
frame-relay traffic-rate
To configure all the traffic shaping characteristics of a virtual circuit in a
single command, use the frame-relay traffic-rate map-class configuration comman
d. To remove the specified traffic shaping from the map class, use the no form
of this command.
frame-relay traffic-rate average [peak]
no frame-relay traffic-rate average [peak]
Syntax Description
average
Average rate, in bits per second; equivalent to specifying the contracted CIR.
peak
(Optional) Peak rate, in bits per second; equivalent to
CIR + Be/Tc = CIR (1 + Be/Bc) = CIR + EIR.
