Question

A network technician is attempting to configure an interface by entering the following command: SanJose(config)# ip address . The command is rejected by the device. What is the reason for this?

1) The device does not support the 'ip address' command
2) The device is not in configuration mode
3) The device is already configured with an IP address
4) The device is not connected to a network

Answer 1

The command 'SanJose(config)# ip address' is rejected because it is incomplete. For an interface IP configuration, the network technician must specify the IP address and subnet mask.

Step-by-step explanation:

If a network technician receives an error when entering the command SanJose(config)# ip address, the reason is most likely that the command is incomplete. To assign an IP address to an interface, the full command should include the IP address and subnet mask, like so: ip address 192.168.1.1 255.255.255.0. Therefore, the device is rejecting the command because it is expecting more information to complete the configuration. The technician is indeed in configuration mode, as indicated by (config) in the command prompt, but without the full command, the device cannot process it
