CompTIA Linux+ XK0-006 (V8) Practice Question

A team of administrators is reviewing Puppet code that relies on expressions such as $facts["os"]["family"] to choose the right package repository for each node. One colleague asks where the data in the $facts hash actually comes from and when it is gathered during a typical agent run. Which explanation is correct?

  • They are discovered by the Facter binary that runs locally on the agent before the catalog request, and the collected key/value pairs are sent with that request.

  • They are generated by an Ansible setup script that the agent downloads during plugin sync and executes after the catalog is applied.

  • They come from environment variables exported by systemd at boot and read by Puppet through a cron job every 30 minutes.

  • They are retrieved from a cached facts file on the Puppet Server after the catalog has already been compiled and then injected into the catalog.
