_________________ is useful when you need to change how the data source is configured on a sheet-by-sheet basis, and when you want to combine databases that don't allow relationships or joins

• A.Union
• B.Data Joining
• C.Data segregation
• D.Data Blending

Correct Answer: D

Explanation
Data blending is performed on a sheet-by-sheet basis and is established when a field from a second data source is used in the view. To create a blend in a workbook already connected to at least two data sources, bring a field from one data source to the sheet-it becomes the primary data source.
Switch to the other data source and use a field on the same sheet-it becomes a secondary data source. An orange linking icon will appear in the data pane, indicating which field(s) are being used to blend the data sources.

True or False: We can disaggregate the data, to see all of the marks in the view at the most detailed level of granularity

• A.True
• B.False

Correct Answer: A

Explanation
Whenever you add a measure to your view, an aggregation is applied to that measure by default. This default is controlled by the Aggregate Measures setting in the Analysis menu.
If you decide you want to see all of the marks in the view at the most detailed level of granularity, you can disaggregate the view. Disaggregating your data means that Tableau will display a separate mark for every data value in every row of your data source.
To disaggregate all measures in the view:
Clear the Analysis >Aggregate Measures option. If it is already selected, click Aggregate Measures once to deselect it.
