How a user interacts with questions and assessments in the content depends on the deployment method and the settings you choose. For example, there are specific pre-assessment and post-assessment options that you can set in the Professional edition of the Knowledge Center. It is important to know your deployment method, understand what user options are available for questions and assessments in that deployment, know if usage tracking is available in your deployment, and have a general understanding of how you want to utilize questions and assessments in your content before you start creating them.
