Selected Answer: B

B. Create a copy of the existing workbook, open it in Tableau Desktop, and connect to the new data source. Update each sheet, using fields from the new data source. Here's a detailed breakdown of why: "Create a copy of the existing workbook, open it in Tableau Desktop...": This is a crucial first step for several reasons: Safety/Version Control: You never modify a live, published dashboard directly without creating a copy. This ensures you have a rollback point and don't break the existing user experience while working on updates. Desktop's Full Functionality: While web editing on Tableau Server/Cloud is powerful, complex data model changes, full data source replacements, and extensive sheet modifications are still best handled in Tableau Desktop, which offers the complete suite of features.
