Which command is used to set the configuration of an Ethernet network interface?

• A. ifconfig
• B. ifstat
• C. netstat - i
• D. sysconfig - v

Answer: (A)

Setting the configuration of an Ethernet network interface is done with the ifconfig command. This utility lets you assign an IP address and subnet mask, set a broadcast address, and bring the interface up or down, effectively configuring how the device communicates on the network. For example, you can assign an IP like ifconfig eth0 192.168.1.5 netmask 255.255.255.0 up to establish the interface’s addressing. The other commands shown are for viewing or reporting information rather than configuring the interface: ifstat and netstat -i display statistics, and sysconfig - v isn’t the standard tool used to set interface parameters. Thus, ifconfig is the appropriate choice for configuring the Ethernet interface.
