| Exam 200-301 | Question id=5496 | Network Fundamentals |
You set up several routers in your lab. Two of them are connected back to back using Data Terminal Equipment (DTE)-to-Data Circuit-terminating Equipment (DCE) cable. You need to configure the clock rate. On which router would you configure the clock rate?
| A. |
the DCE | |
| B. |
the DTE | |
| C. |
The clock rate is set by default | |
| D. |
The clock rate cannot be configured |
The clock rate is set on the Data Circuit-terminating Equipment (DCE) device. DCE is also known as Data Communications Equipment.
DCE terminates a physical WAN connection and provides clocking and synchronization of a connection between two locations and connects to a DTE. The DCE category includes equipment such as CSU/DSUs and modems. If you were connecting a router to a WAN link, the router would be the DTE end and would be connected to a CSU/DSU or a modem. Either of these devices would provide the clocking.
DTE is an end-user device, such as a router or a PC that connects to the WAN via the DCE device.
Other options are incorrect. By default, no clock rate is configured, but can be set on a DCE device by using the clock rate [bps] command.
