Cisco IOS Configuration Register

What can you use to examine the configuration register in Cisco IOS?

a) show config-register
b) display config-register
c) view register-config
d) show version

Answer:

The correct Cisco IOS command to examine the configuration register is 'show version'.

In Cisco IOS, you can use the command 'show version' to examine the configuration register. This command not only displays the configuration register value but also provides additional information such as the Cisco IOS version, hardware type, and installed memory. The output of the show version command includes a line that indicates the current configuration register value.

For example, when you enter the command 'show version' on a Cisco router or switch, you will see a line that starts with 'Configuration register is' followed by the actual configuration register value.

By using the show version command, you can easily view and confirm the configuration register settings on your Cisco device. It is an essential command for troubleshooting and verifying the device's configuration.
