Which user role is primarily responsible for tenant-level management and configurations?

The Super User role is primarily responsible for tenant-level management and configurations in a marketing cloud environment. This role typically has comprehensive access to various system settings, user management, and configurations that are essential for the overarching setup and functionality of the platform.

Super Users can perform critical tasks such as managing user permissions, configuring integrations, and setting up overall system parameters that affect all users within the tenant. Their elevated access level allows them to ensure that the marketing cloud instance runs smoothly and aligns with the organization's business objectives.

While other roles, like Full Users and Admin Only, have specific responsibilities and access levels, they do not encompass the full scope of tenant management and configurations that the Super User role does. Basic Users have limited access, intended mainly for executing specific tasks without the capability to alter system-wide settings or configurations. Therefore, the Super User's extensive permissions and responsibilities make it the correct answer in this context.
