CompTIA Linux+ XK0-006 (V8) Practice Question

The correct command is ip address add 10.0.0.5/8 dev eth0. The ip address add command is part of the modern iproute2 suite and is used to add an additional IP address to a network interface. This does not interfere with any existing IP addresses on the interface.

• ip address set is incorrect because set is not a valid action for the ip address command. The primary actions are add, del, and show.
• ip route add is incorrect because it is used to modify the system's routing table, which dictates how packets are forwarded to other networks, not to assign an IP address to a local interface.
• ifconfig eth0:1... is incorrect because ifconfig is a legacy command from the net-tools package. While it was used to create IP aliases, the modern and tested standard is the ip command from the iproute2 package.
