In the network environment shown in the figure, the two routers are connected back to back with serial ports. The speed of the interconnection link should be set to 2Mbps . The following statement is correct ______ .

A . Need to determine the interface type and cable meet
B . 24 regulations
C . Use the baudrate 2048000 command configuration on the RTA synchronization port
D . Use the baudrate 2048000 command configuration on the RTB synchronization port
E . Use the virtual-baudrate 2048000 command configuration on the RTB synchronization port
F . In RTA using synchronous port bandrate 2048000 command configuration, RTB using synchronous port virtual-baudrate 2048000 command to configure

Answer: B

Explanation:

V . 24 Support same and asynchronous: asynchronous maximum rate 115200bps synchronous maximum rate 64000bps

V . 35 only supports synchronization: the highest rate is 2048000bps = 2Mbps

Configure bandwidth on DCE

DCE (Data Control Equipment) operator equipment, providing synchronous clock signal between DCE and DTE

DTE (Data Terminal Equipment) user equipment that accepts the clock signal provided by DCE
