______ files are shortcuts for quickly connecting to the original data that you use often. Data source files do not contain the actual data but rather the information necessary to connect to the actual data as well as any modifications you've made on top of the actual data such as changing default properties, creating calculated fields, adding groups, and so on.

You can ______ your data to combine two or more tables by appending values (rows) from one table to another
Correct Answer:D
You can union your data to combine two or more tables by appending values (rows) from one table to another. To union your data in Tableau data source, the tables must come from the same connection.
For example, suppose you have the following customer purchase information stored in three tables, separated by month. The table names are "May2016," "June2016," and "July2016."
A union of these tables creates the following single table that contains all rows from all tables.

Suppose you create a bar chart by dragging a dimension to the Column shelf and a measure to the Rows shelf. Which of the following would create a stacked bar chart?
Correct Answer:C
Very important question for the exam and appears quite a lot too.
The correct answer is - By dragging another dimension to Color on the Marks card.
This is what the question says we have already created. Now to convert this into a Stacked bar chart, we will drop another dimension on Color in the Marks card.
The rest won't create stacked bar charts, and hence are incorrect choices. The best way to answer such questions on the real exam is to quickly do what the options say and see if
they satisfy the requirements in the question.
