A CentOS 8 server uses NetworkManager. The admin needs to create a new persistent connection named 'static-eth0' on interface eth0 with IP 192.168.50.10/24 and gateway 192.168.50.1. The connection must be activated immediately. Which command sequence accomplishes this?

ip addr add 192.168.50.10/24 dev eth0 && ip route add default via 192.168.50.1

nmcli con add type ethernet con-name static-eth0 ifname eth0 ipv4.addresses 192.168.50.10/24 ipv4.gateway 192.168.50.1 ipv4.method manual && nmcli con up static-eth0

echo -e 'IPADDR=192.168.50.10\nNETMASK=255.255.255.0\nGATEWAY=192.168.50.1' > /etc/sysconfig/network-scripts/ifcfg-eth0

nmcli dev add type ethernet con-name static-eth0 ifname eth0 ipv4.addresses 192.168.50.10/24

A RHEL 8 server has a single NIC named enp3s0. The admin needs to change the static IP from 192.168.10.10/24 to 192.168.10.50/24, keep the same gateway 192.168.10.1, and make the change survive a reboot. The system uses NetworkManager. Which file should the admin edit to make this change persistent?

/etc/sysconfig/network-scripts/ifcfg-enp3s0

Which nmcli command activates a connection profile named 'office'?

nmcli connection add con-name office type ethernet

nmcli connection modify office ipv4.addresses 192.168.1.10/24

Which nmcli command creates a new connection profile named 'office'?

nmcli connection add con-name office type ethernet

nmcli connection modify office ipv4.addresses 192.168.1.10/24

Which directory contains per-interface configuration files on Red Hat-based systems?

/etc/sysconfig/network-scripts/
