That's just one example. You can back-end it with any script or DB containing node information. When the Puppet client connects the master queries the external node script and says "Do you have a host called insertnamehere?". This allows you to: a) saves you defining each node in a Puppet manifest and allowing a greater flexibility of maintenance. b) potentially query external data sources (such as LDAP or asset management stores) that already know about your hosts meaning you only maintain said information in one place.
