Which of the following is NOT a step in the iterative Model Based Approach used by Puppet?

The iterative Model Based Approach used by Puppet consists of a cycle where specific steps are repeated to refine and enforce the desired state of infrastructure. The primary steps include defining, enforcing, and reporting.

Defining involves establishing what the desired state of the infrastructure or application should be, often through the creation of configuration code. Enforcing is the process of applying this code to ensure that the actual state matches the defined state, thereby managing changes in the environment. Reporting includes gathering data on the state of the infrastructure, which helps in assessing compliance with the defined configurations and improving infrastructure management over time.

Provisioning, while an important concept in the broader context of managing infrastructure, is not a formal step in this specific iterative approach. It typically refers to the act of setting up resources, such as virtual machines or containers, rather than the follow-through steps involved in ensuring that those resources maintain the desired configuration. Consequently, it does not fit into the core iterative steps of definition, enforcement, and reporting in the Model Based Approach.
