Ensure the unlicensed node is properly networked and configured to communicate with the licensed nodes Proper networking and configuration for communication with the li-censed nodes are crucial when setting up an unlicensed node. This ensures that the unlicensed node can effectively handle background tasks and communicate results back to the main server, maintaining the overall efficiency of the Tableau Server deployment. Option A is incorrect because the processing power requirement of an unlicensed node does not necessarily have to be higher than that of licensed nodes; it depends on the specific tasks assigned to it. Option B is incorrect as the physical location of the unlicensed node is not a critical factor, as long as it is well-connected to the licensed nodes over the network. Option D is incorrect because having a separate storage system is not a primary requirement for an unlicensed node; it primarily needs to be configured for effective task handling and communication with the licensed nodes.
