NEW QUESTION # 192
________________ can only create header. _______________ will create header and axis both.
- A. Dates, Strings
- B. Dimensions, Measures
- C. Groups, Sets
- D. Measures, Dimensions
Answer: B
Explanation:
Using the Sample superstore as a reference:
1) Let's plot a bar chart showing SUM(Quantity) for each Segment:
2) Right click on the x-axis (Segment):
Notice we don't have an option to edit the axis, only header. This is because only continous values form the AXIS.
3) Similarly, right click on the y-axis (Quantity):
Now we have the option to edit BOTH the axis and the header.

NEW QUESTION # 193
How does Tableau know at which level to aggregate values?
- A. Values are always aggregated at the level of the Date Part
- B. Tableau doesn't aggregate values, we do!
- C. Aggregation is always done by using Tableau special formulas
- D. Values are always aggregated at the level of granularity of the worksheet.
Answer: D
Explanation:
In Tableau, you can aggregate measures or dimensions, though it is more common to aggregate measures. Whenever you add a measure to your view, an aggregation is applied to that measure by default. The type of aggregation applied varies depending on the context of the view.
When you add a measure to the view, Tableau automatically aggregates its values. Sum, average, and median are common aggregations; for a complete list, see List of Predefined Aggregations in Tableau.
The current aggregation appears as part of the measure's name in the view. For example, Sales becomes SUM(Sales). Every measure has a default aggregation which is set by Tableau when you connect to a data source. You can view or change the default aggregation for a measure-see Set the Default Aggregation for a Measure.
You can change the aggregation for a measure in the view from its context menu:

NEW QUESTION # 197
What term is used to describe the following picture?
- A. Hierarchy
- B. Larger image
- C. Group
- D. Parameter
- E. Set
Answer: E
Explanation:
When you connect to a data source, Tableau automatically separates date fields into hierarchies so you can easily break down the viz. You can also create your own custom hierarchies. For example, if you have a set of fields named Region, State, and County, you can create a hierarchy from these fields so that you can quickly drill down between levels in the viz.
NEW QUESTION # 198
Which of the following would you use to connect to multiple tables in a single data source at once?
- A. A Set
- B. A Hierarchy
- C. A Join
- D. A Blend
Answer: C
Explanation:
The data that you analyze in Tableau is often made up of a collection of tables that are related by specific fields (that is, columns). Joining is a method for combining data on based on those common fields. The result of combining data using a join is a virtual table that is typically extended horizontally by adding columns of data.
For example, consider the following two tables originating from a single data source:
We can combine these 2 tables, simply by joining the tables on ID to answer questions like, "How much was paid in royalties for authors from a given publisher?". By combining tables using a join, you can view and use related data from different tables in your analysis.
NEW QUESTION # 199
Which of the following are valid ways to trigger actions for a Dashboard?

NEW QUESTION # 200
Suppose I have the following view. What will be the total number of marks if I drag a new measure to the row shelf vs the column shelf?
- A. If dragged to row shelf : 7 marks ; If dragged to column shelf : 7 marks
- B. If dragged to row shelf : 7 marks ; If dragged to column shelf : 14 marks
- C. If dragged to row shelf : 14 marks ; If dragged to column shelf : 14 marks
- D. If dragged to row shelf : 14 marks ; If dragged to column shelf : 7
marks
Answer: D
Explanation:
This is a tricky question often asked in the exam.
If we drag a new measure to the row shelf, the following happens:
We now have 2 rows, and the same 7 columns for both these rows. Therefore, 2x7 = 14 marks!

But if we drag the same measure to the column shelf, we have just 1 row and a chart created for each of the columns. So (1x7) = 7 marks!
