Creating a dedicated Tableau user and group, and setting appropriate ownership and permissions on the Tableau directories For a successful Tableau Server installation on Linux, it's crucial to create a dedicated Tableau user and group. Setting appropriate ownership and permissions on the Tableau directories ensures that Tableau Server has the necessary access rights to operate correctly while maintaining the security and integrity of the system. Option A is incorrect because as-signing the Tableau Server user to the root group poses significant security risks and is not recommended.Option C is incorrect as giving all users administrative privileges is unnecessary for Tableau Server installation and could compromise system security. Option D is incorrect because disabling the firewall does not affect file system permissions and is not a recommended practice during installation.
