Cisco CCNA mock exam questions sample test – Question 441

.Which of the following commands would allow you to determine the bandwidth of an interface?

A. show interfaces
B. show interfaces accounting
C. show cdp
D. show cdp neighbors

Correct Answer: A

The show interfaces command shows information about each interface including a section on the bandwidth of the connection. If you wanted to locate this information in the output, it
would be in the third down line as follows:
MTU 1500 bytes, BW 10000 Kbit, DLY 100000 usec, rely 255/255, load 1/255
Where BW = bandwidth
The show interfaces accounting command focuses on the relative amounts of traffic going through each interface, but does not indicate the bandwidth.
The show cdp command shows information about the Cisco Discovery protocol, a Layer 2 protocol used by Cisco devices to advertise their existence and capabilities to other Cisco
devices ion the network.
The show cdp neighbors command shows information about each discovered neighbor, but does not display the bandwidth of an interface.
