You can find out-of-the-blue puppet interview questions just like this one. The communication between Puppet agent nodes and Puppet Masters depends on HTTPS with client verification. The Puppet Master has an HTTP interface with different endpoints. Agents make an HTTPS request to the endpoints for requesting or submitting anything to the master. Client verification, in this case, implies the need for SSL certificate. The SSL certificates help in verifying the identity of the other party. Puppet also has an in-built certificate authority for effective management of certificates.
