A Fedora workstation uses NetworkManager. The admin needs to change the DNS servers for the active wired connection 'Wired connection 1' from the DHCP-provided values to 1.1.1.1 and 9.9.9.9. The change must persist across reboots. Which command accomplishes this?

systemctl restart NetworkManager

nmcli dev set enp0s3 ipv4.dns '1.1.1.1 9.9.9.9'

echo 'nameserver 1.1.1.1' > /etc/resolv.conf

nmcli con mod 'Wired connection 1' ipv4.dns '1.1.1.1 9.9.9.9' && nmcli con up 'Wired connection 1'

Which file is commonly used to define persistent static routes on Red Hat-based systems?

/etc/sysconfig/network-scripts/route-eth0

Which of the following is a key benefit of using persistent network configuration over runtime commands?

Settings are automatically reapplied after a system reboot
