Q.56
Which element is used to define the rate, in bits per second, that a Frame Relay switch agrees to transfer data?
A.Clock rate (CR).
B.Committed Information Rate (CIR)
C.Local management interface (LMI)
D.
E.Committed Rate Measurement Interval (CRMI)
Answer: B

Incorrect Answers:
A is incorrect; clock rate is the transmission medium speed, which is determined by modem clocking.
C is incorrect; LMI is a signaling standard between the router device and the Frame Rekay switch that is responsible for managing the connection and maintaining the status between the devices.
D is incorrect; DLCI is addressing used to identify virtual circuits.
E is incorrect; this is the sampling period used in controlling CIR, but is not the rate itself.
