Describe Puppet in brief
In short, Puppet is an open-source automation platform that performs all types of deployment, configuration, and server management tasks. To be specific, Puppet is a DevOps that specializes in automating administration infrastructure. With this, a server administrator finds it extremely straightforward and simple to manage all the nodes present in a specific server.
What is Puppet Infrastructure based on?
As an open-source platform, Puppet utilizes a master-slave architecture. Using this architecture, a Puppet slave device requests a secure and encrypted connection from the Puppet master. In that case, the Puppet slave receives a special configuration from the Puppet master to alter a specific device or perform a particular task.

The Puppet manifest is a crucial part of Puppet’s capabilities, which you cannot be ignorant of during your interview.
Puppet is commonly used by businesses and offices to automate their network management. With Puppet, you can store detailed documentation of Puppet nodes in Puppet servers specifically designed for your organization. The documentation for these Puppet nodes is called the Puppet manifest.
What are Puppet Modules?
Apart from Puppet manifests, Puppet data also exists in a Puppet server. Files, templates, and all other information pieces are considered Puppet data. Puppet modules are collections of Puppet manifests and Puppet data from multiple Puppet servers.
What is a Facter in a Puppet Server?
Every automation software comes with a dedicated library to store the information related to the agents present in a server. For Puppet, the library is named as Facter. The main responsibility of Factor is to inform the Puppet master of a Puppet server about the activities of facts of the Puppet agents present in that server. From Network settings to IP addresses, every information related to Puppet agents is reported to Puppet master by Facter.
What does a Puppet Catalog do?

What is a Puppet Class?
As a tricky one, this question can make an interview session difficult for an IT interviewee. However, the main concept of Puppet class is not that hard. In simple words, Puppet classes are blocks of Puppet codes that the platform stores to make use of them in the future. As a Puppet user, you are supposed to deploy a Puppet class in the main Puppet server you’re using according to your requirements. The platform doesn’t deploy Puppet classes automatically.
What do you know about the Communication process between Puppet Agents and Puppet Masters?
The communication process between Puppet agents and Puppet masters relies on HTTPS interfaces. Every Puppet master comes with numerous HTTPS endpoints. To communicate with the Puppet master or to prompt it to do something, a Puppet agent needs to raise a request to a specific endpoint. Then, the Puppet master gets notified about the request and authorizes the connection. That’s how a secure and encrypted connection is created between Puppet agents and Puppetmasters.
What does the Stand-alone Architecture in a Puppet Network mean?
