Depending on the host's configuration, which of the following files can be used to turn on and off network services running on a host? (choose two correct answers.)

The `/etc/profile` file is a system-wide initialization script for shell environments and does not control the enabling or disabling of network services.

The `/etc/services` file maps service names to port numbers but does not contain configuration that directly turns network services on or off.

The `/etc/inetd.conf` file is the configuration file for the `inetd` super-server, which listens for incoming connections on specific ports and launches the corresponding service on demand; commenting out or removing entries here effectively turns services on or off.

The `/etc/xinetd.conf` file (or files in `/etc/xinetd.d/`) is the configuration for `xinetd`, an enhanced `inetd` super-server, where entries for network services can be enabled or disabled to control their availability.

The `/etc/host.conf` file determines the order in which name resolution sources are consulted (e.g., files before DNS) and does not control the operational status of network services.
