You have connected two routers in a lab using a Data Terminal Equipment (DTE)-to-Data Circuit-terminating Equipment (DCE) cable.
Which command must be issued on the DCE end for the connection to function?
A.
bandwidth
B.
no clock rate
C.
clock rate
D.
no bandwidth
Explanation:
You should issue the clock rate command on the DCE end for the connection to function. The clock rate is set on the Data Circuit-terminating Equipment (DCE)
device. DCE is also known as Data Communications Equipment.
The DCE terminates a physical WAN connection, provides clocking and synchronization of a connection between two locations, and connects to a DTE. The DCE
category includes equipment such as CSU/DSUs, NT1s, and modems. In the real world, the clock rate is provided by the CSU/DSU end at the telcom provider. In a
lab, you must instruct the DCE end to provide a clock rate.
The DTE is an end user device, such as a router or a PC, which connects to the WAN via the DCE device.
You would not issue the bandwidth command. This command is used to inform the router of the bandwidth of the connection for purposes of calculating best routes
to locations where multiple routes exist. It is not necessary for the link described to function.You should not issue the no clock rate command. This command is used to remove any previous settings implemented with the clock rate command.
You would not issue the no bandwidth command. This command is used to remove any previous settings implemented with the bandwidth command
