How can user permissions be managed in Tableau Server?

User permissions in Tableau Server are managed effectively by defining roles and assigning permissions. This process allows administrators to control what users can view, interact with, or modify within the server environment based on their assigned roles. Different roles, such as Viewer, Explorer, or Creator, come with specific permissions that dictate the level of access and functionality available to each user. By carefully managing these roles and permissions, organizations can ensure that sensitive data is protected while allowing appropriate levels of access to users according to their needs.

The other choices do not correctly address the effective management of user permissions. Deleting user accounts regularly does not contribute to permission management; it could instead hinder collaboration or access to necessary data. Limiting access to only administrators would restrict the utility of Tableau Server for broader teams and would not accommodate the need for users who must interact with data. Enabling all users to edit dashboards could lead to uncontrolled changes and potential data integrity issues, undermining the structured approach to managing permissions.
