What must the customer complete to prepare for user addition and environment management?

To effectively prepare for user addition and environment management, it is crucial that the customer completes pre-deployment training. This training provides essential knowledge and skills necessary for understanding the Tanium platform and its functionalities before any actual deployment begins. It ensures that users are familiar with the system's architecture, security protocols, and operational procedures, which are vital for smooth user integration and effective management of the environment.

Pre-deployment training typically covers topics such as system configuration, user roles, permission settings, and best practices for managing the Tanium environment. By completing this training, the customer is equipped to handle user additions confidently, ensuring that they are integrated into the system correctly and can operate within their defined roles while maintaining security and efficiency.

The other options, while valuable, do not specifically focus on the comprehensive preparation needed for managing users and the environment in the context of Tanium deployments. They may offer beneficial insights or skills, but pre-deployment training is explicitly aimed at laying the groundwork necessary for the specific tasks and responsibilities that come with managing users post-deployment.
