Cisco CCNA mock exam questions sample test – Question 120

.You run the following command:
switch# show ip interface brief
What information is displayed?

A. A summary of the IP addresses and subnet mask on the interface
B. A summary of the IP addresses on the interface and the interface’s status
C. The IP packet statistics for the interfaces
D. The IP addresses for the interface and the routing protocol advertising the network

Correct Answer: B

Explanation:
The command show ip interface brief displays a summary of the IP address on the interface and the interface’s status. The status shows whether the interface is up. This command is
useful when you are connected to a router or switch with which you are not familiar, because it allows you to obtain the state of all interfaces or switch ports.
Sample output of this command is shown below:
This command does not display subnet mask information. You should use other commands, such as show ip interface or show run interface, to verify the subnet mask.
IP statistics about the interface are displayed with the command show ip interface. Adding the brief keyword tells the switch to leave out everything but the state of the interface and its
IP address.
To view the routing protocol advertising an interfaces network, you would use the command show ip protocol.
