Refer to the exhibit.
Which action must you take to enable the WAN link to function properly?
A.
Enter a clock rate on the DCE interface.
B.
Enter a clock rate on the DTE interface.
C.
Enter a compression algorithm on both interfaces.
D.
Configure both interfaces for HDLC encapsulation.
When connecting a serial cable to the serial interface of the router, clocking is provided by an
external device, such as a CSU/DSU device. A CSU/DSU (Channel Service Unit/Data Service
Unit) is a digital-interface device used to connect a router to a digital circuit. The router is the DTE
(Data Terminal Equipment) and the external device is the DCE (Data Communications
Equipment), where the DCE provides the clocking. However, in some cases we might connect two
routers back-to-back using the routers’ serial interfaces (ExamplE. Inside the router labs). Each
router is a DTE by default.
Since clocking is required to enable the interface, one of the two routers should function as DCE
and should provide clocking. This can be done by using the “clock rate” command, from the
interface configuration mode.
