When a router is connected to a Frame Relay WAN link using a serial DTE interface, how is the clock rate determined?
A. Supplied by the CSU/DSU
B. By the far end router
C. By the clock rate command
D. By the Physical layer bit stream timing
Answer: Option A
Solution (By Examveda Team)
Clocking on a serial interface is always provided by the CSU/DSU (DCE device). However, if you do not have a CSU/DSU in your nonproduction test environment, then you need to supply clocking with theclock rate command on the serial interface of the router with the DCE cable attached.
