Which of the following lines would an administrator find in the file /etc/nsswitch.conf?

`order hosts,bind` is a directive found in older `resolv.conf` or similar files for specifying resolver order, not in `nsswitch.conf`.

`192.168.168.4 dns-server` is an entry typically found in `/etc/hosts` to map an IP address to a hostname, not a directive for `nsswitch.conf`.

The `/etc/nsswitch.conf` file configures the order in which Name Service Switch services search for information. The line `hosts: files dns` is a common entry specifying that hostname lookups should first consult `/etc/hosts` (`files`) and then use DNS servers.

`domain mycompany.com` is a directive typically found in `/etc/resolv.conf` to specify the default domain for hostname resolution, not a configuration line for `nsswitch.conf`.
