Which configuration file is typically used for network interface parameters?

The configuration file typically used for network interface parameters is /etc/network/interfaces. This file is a standard in Debian-based distributions like Debian and Ubuntu, and it allows administrators to define the settings for network interfaces, including IP addresses, network masks, gateway information, and the method of configuration (such as whether to use DHCP or static IP addressing).

This file plays a crucial role in establishing network connectivity during the system boot-up sequence, as the parameters defined within it dictate how the network interfaces behave. By configuring the interfaces properly in this file, a system administrator can ensure that necessary network services are available and that the system can communicate with others over the network.

The other options represent different configurations or functionalities unrelated to direct network interface parameters. For example, /etc/sysconfig/network is primarily used in Red Hat-based distributions for overall network settings, /etc/netconfig is not commonly utilized in modern Linux systems, and /etc/hosts is mainly for hostname resolution and mapping IP addresses to hostnames, rather than configuring the network interfaces themselves.
