Cisco CCNA mock exam questions sample test – Question 422

.Which Cisco IOS command would you use to troubleshoot IP addressing problems?

A. ipconfig /all
B. show config
C. show running-config
D. show config-file


Correct Answer: C

Explanation:
The show running-config command will help troubleshoot IP addressing problems, because it shows the details of the router configuration, including the IP address configured on each
interface.
The ipconfig /all command is a Microsoft command used to verify IP address configuration on a workstation running Windows. This is not a valid Cisco command.
The show config command has been replaced by the show startup-config command. Both of these commands are used to display the startup configuration of the router stored in
NVRAM.
The show config-file command is not a valid Cisco command.
