Which of the following processes cannot be moved from the initial node in Tableau Server?

The License Service, also known as the License Manager, is integral to Tableau Server's architecture and is responsible for managing the licensing of Tableau products. This service ensures that the server has the appropriate licenses available and manages aspects like user counts and feature accessibility related to the licenses.

The reason this service cannot be moved from the initial node is that licensing is fundamentally tied to the server's operational core and is necessary for the functioning of all other components. Since it manages licensing for the entire server environment, it must run on the primary or initial node to maintain central control and ensure that all distributed components have access to the licensing information they need.

On the other hand, components like the Data Server, Backgrounder, and Cache Server can be scaled and redistributed across nodes in a Tableau Server environment. These services handle specific tasks related to data processing and performance, thus allowing for more flexibility in their deployment to optimize resource utilization and manage workloads efficiently across multiple nodes.
