Which syntax is used to declare a package resource in Puppet?

The syntax used to declare a package resource in Puppet is "package { 'resource-name': }". In this format, the term "package" indicates that the resource being declared is of the package type. The curly braces enclose the resource declarations where the name of the package is specified in quotes. This structure follows Puppet's declarative language conventions, which allow administrators to define the desired state of system resources.

Using this syntax, Puppet understands that a new package resource is being defined, and it can then manage the installation, removal, or state of that package on the managed node. The standard practice in Puppet is to use this clear and concise structure to define resources, enabling easy readability and maintainability of configuration files.

Other syntaxes listed do not conform to Puppet's resource declaration format. They either lack the proper structure or use incorrect keywords that would lead to syntax errors in a Puppet manifest. By using the correct syntax, you ensure that Puppet understands your intent and can apply the configuration correctly.
