An administrator is troubleshooting a legacy application that expects to see an interface named eth0:1 with IP 10.0.0.5. The administrator creates the alias using the ip command, but after a reboot the alias is gone. What is the most likely reason?

The alias was created on the wrong interface.

The alias was not added to a persistent configuration file.

The application requires the alias to be created before the interface is up.

The kernel does not support IP aliases.

Which file is used to persist network configuration on a Red Hat-based system?

/etc/sysconfig/network-scripts/ifcfg-*

A Linux administrator has just created a bond interface bond0 in active-backup mode using two NICs, but the bond is not active. The administrator needs to add eth1 to the bond immediately without rebooting. Which command accomplishes this?

echo eth1 > /sys/class/net/bond0/bonding/slaves
