What is the effect of the command?

Your Oracle Linux server has a network interface eth0 but the ifcfg-eth0 file is missing from
the /etc/sysconfig/network-scripts directly. To set the IP address for the interface, you run
this command as root: [root@station1]# ifconfig eth0 192.168.0.1 up What is the effect of
the command?

A.
The IP address 192.168.0.1 is not assigned to eth0 because the netmask is not
specified.

B.
The IP address 192.168.0.1 is assigned to eth0, but the interface is not activated until the
network service is reloaded.

C.
The IP address 192.168.0.1 is assigned to eth0, but the interface is not activated until the
network service is restarted.

D.
The IP address 192.168.0.1 is assigned to echo with the default netmask for that
address, and the interface is activated immediately.
