How is a new group created in Tableau Server?

Creating a new group in Tableau Server involves using the tabcmd command-line utility, which allows for administrative tasks to be performed via scripts or command prompts. The command relevant to establishing a new group in this context is tabcmd creategroup <group name>. This command is specifically designed for the purpose of creating groups within Tableau Server, enabling administrators to easily organize users for permissions and access control.

By using the correct command, administrators can efficiently create a new group without needing to navigate through the graphical interface, which can save time, especially when managing large numbers of users and groups.

The other choices, while related to user management, do not serve to create a new group. The option that mentions synchronizing a group would help in updating or syncing existing groups, but it does not initiate the creation of a new one. Similarly, adding users to an already existing group or creating users does not pertain to group creation itself, emphasizing the direct purpose of the creategroup command. Thus, the choice of tabcmd creategroup <group name> correctly addresses the action of creating a new group in Tableau Server.
