Which Cisco IOS command should you use to set the clock speed to 64 kb/s on a serial interface on a Cisco router? (Source: Introducing the Review Lab)
Correct Answer
C. Clock rate 64000
Explanation
The correct answer is "clock rate 64000". This command is used to set the clock rate on a serial interface of a Cisco router. The clock rate is specified in bits per second, so the value should be given in the form of the number of bits per second. In this case, the desired clock speed is 64 kb/s, which is equivalent to 64000 bits per second. Therefore, the correct command to set the clock speed to 64 kb/s is "clock rate 64000".
