Puppet classes are primarily composed of which of the following?

Puppet classes are primarily composed of resources. Resources in Puppet represent the various components of the system that Puppet manages, such as packages, services, files, users, and more. By grouping related resources within a class, Puppet allows for the structured management of configurations, making it easier to enforce specific states or properties across managed systems.

Each resource can define desired attributes and states, and the class serves as a way to encapsulate and reuse these configurations. This organization helps in maintaining consistent setups across multiple nodes while streamlining the application of resource definitions.

Definitions, variables, and functions are all important aspects of Puppet's functionality, but they serve different purposes. Definitions are used to create reusable chunks of Puppet code, variables hold dynamic data that can change between different runs, and functions are used to perform specific operations and computations. While these components can be part of a class, the core structure of a Puppet class fundamentally revolves around resources.
