Question restatement: After connecting to data in Tableau, any changes you make to the data (such as the data type) will also be made in the original source data.

Option 1: True. This would assert that edits in Tableau propagate back to the source data. In practice, Tableau typically operates in a read-only fashion with respect to the original data source. Unless you are using a specialized write-back feature or a data source specifically configured for two-way syncing (which is not the default behavior), changes made in Tableau do not modify the underlying source.

Option 2: False. This is the correct characterization for most standard Tableau workflows. When you adjust fields, data types, or perform transformations in Tableau, these changes affect only the Tableau data engine, extracts, or the workbook’s metadata, not the original data source itself. For live connections, Tableau queries the source data as needed and does not overwrite it. For extracts, the changes apply to the extracted data within Tableau, not the source unless you explicitly refresh or replace the extract, which still targets the local extract, not the source.

Analysis of why the other choice is incorrect: The statement labeled True implies automatic, bidirectional synchronization with the original data, which is not a default feature of Tableau. Without a dedicated write-back tool or a database trigger configuration, edits remain local to Tableau and do not alter the source. Therefore, treating Tableau edits as impacting the source would be a misconception about typical data workflow in Tableau.

Additional nuance: If one uses specific configurations such as write-back extensions, materialized views, or certain data governance setups, edits could be propagated under tightly controlled conditions. However, these are advanced setups and not the standard behavior described in the question.

In summary, the standard behavior is that changes made in Tableau after connecting to data do not alter the original source data, so the statement is false. The reasoning hinges on understanding read-only interactions with source data in typical Tableau workflows and the distinction between live connections versus extracts versus any specialized write-back arrangements.
