Router A has a 512K-access port into the frame relay cloud. Router B has 128K-access port into
the frame relay cloud. The two routers are connected with symmetrical PVCs that are configured
for 64K committed information rate (CIR). What Frame Relay Traffic Shaping map-class subcommand should be entered on Router A to prevent workstation A from overrunning the access
port on Router B?

A.
frame-relay traffic-rate 128000 512000

B.
frame-relay traffic-rate 64000 512000

C.
frame-relay traffic-rate 512000 64000

D.
frame-relay traffic-rate 128000 64000

E.
frame-relay traffic-rate 64000 128000
