If a node has to be removed that was running the only instance of CFS, what must be done?

When a node running the only instance of the Central File Store (CFS) needs to be removed, it is critical to ensure that CFS is operational on another node before proceeding with the removal. This is necessary because the CFS acts as a centralized repository for storing Tableau Server files and other essential resources.

By adding CFS to another node, you provide redundancy and ensure that the server can maintain the necessary functionality for content storage and access. This approach also helps in preventing any downtime or data loss that may occur if the CFS is removed without an alternative in place.

The other choices reflect actions that would either lead to potential data loss or do not address the need to have a CFS instance available on another node, which is vital for maintaining the integrity and availability of the Tableau Server environment.
