A server's hostname is currently 'old-server'. The administrator needs to change it to 'new-server' permanently and ensure it is used for local name resolution. Which set of commands should the administrator run?

nmcli general hostname new-server

hostnamectl set-hostname new-server && echo '127.0.1.1 new-server' >> /etc/hosts

echo 'new-server' > /etc/hostname && sysctl kernel.hostname=new-server

A Debian server's /etc/network/interfaces file contains the following lines for the interface enp3s0: ``` auto enp3s0 iface enp3s0 inet static address 192.168.1.10 netmask 255.255.255.0 gateway 192.168.1.1 ``` The administrator wants to add a second static IP address 192.168.2.10/24 to the same interface. Which configuration should be added?

Add 'up ip addr add 192.168.2.10/24 dev enp3s0' to the existing stanza

Add a second 'iface enp3s0 inet static' block with the new address

Change the existing 'address' line to '192.168.2.10'

Create a new file /etc/network/interfaces.d/enp3s0 with the new address

Which configuration file is used to define a static IP address for a network interface on a Debian-based system?

/etc/sysconfig/network-scripts/ifcfg-eth0

A technician is troubleshooting why a Linux server cannot resolve the hostname 'db1.internal.example.com'. The server's /etc/resolv.conf contains 'nameserver 10.0.0.53' and 'search internal.example.com'. The technician runs `getent hosts db1` and receives no output, but `getent hosts db1.internal.example.com` returns the correct IP. Which configuration change would fix the resolution of the short hostname?

Change the 'search' line in /etc/resolv.conf to 'search internal.example.com example.com'

Verify that the 'search' directive in /etc/resolv.conf is not commented out and is on a single line

Run `systemctl restart systemd-resolved`

Add 'db1' to the /etc/hosts file
