How can you identify a manifest file in Puppet?

A manifest file in Puppet is defined by its purpose and format. It specifically contains Puppet Domain Specific Language (DSL) code, which is used to define the desired state of resources on a host. This code allows system administrators to automate the configuration management of resources effectively.

The .pp extension is a recognized convention in Puppet for manifest files, indicating that the file contains the relevant Puppet DSL instructions. This allows users and the Puppet system to easily identify the file's role and content type.

Other options do not accurately describe manifest files in Puppet. For instance, a manifest does not use the .yaml extension, as that is typically associated with YAML files, which are used for configurations and data in many contexts, but not as Puppet manifests. Furthermore, manifests are not compiled binaries; they are plain text files that are interpreted by Puppet during execution. Additionally, while JSON files can be used for configurations, they do not directly generate manifest files. Puppet manifests are distinct and specifically formatted files that adhere to Puppet's DSL for resource management.
