Which two settings in puppet.conf are required to connect the Puppet master to an external node classifier?

The correct choice identifies the essential settings needed to establish a connection between the Puppet master and an external node classifier (ENC). Specifically, the configuration options 'node_terminus' and 'external_nodes' play critical roles in this integration.

The 'node_terminus' setting in puppet.conf defines how Puppet will determine the node's configuration during the compilation phase. This setting can be configured to use various backends, and when set to connect with an ENC, it signals Puppet to retrieve node data from the specified node classifier external to the Puppet infrastructure.

The 'external_nodes' setting is crucial as it specifies the location—usually a URL or an API endpoint—where Puppet can access the external node classifier. This ensures that Puppet masters can communicate effectively with the ENC, fetching the necessary configurations for each node before compiling their manifests.

Together, these two settings enable seamless integration with an external node classifier, allowing Puppet to dynamically retrieve node-specific configurations and manage resources more effectively across different environments or setups.
