Answer - A - You should edit the /etc/sysconfig/network/ifcfg-modem0 file to edit the configuration of an internal 56 K modem that you have installed in your Linux system recently so that it works with your ISP.

Key Takeaway: A modem interface is installed the same way as an Ethernet interface. You should install a new interface named modem0. You should use the /etc/sysconfig/network/ifcfg-modem0 file to configure this device. To dial the connection, you need to enter ifup modem0 at the shell prompt. To close the connection, you need to enter ifdown modem0.
