NEW QUESTION 38
Using the CoffeeChain table, create a crosstab showing the Total Expenses per State and add Column Grand Totals to the view. Now group the states of New York, California and Washington. What percent of the total sales does this group contribute?
- A. 25.79%
- B. 27.73%
- C. 23.39%
- D. 29.49%
Answer: B
Explanation:
Explanation
We need to use the concept of Groups for this question. Follow along:
1) First, Drag State to the Rows shelf, and Total Expenses to the Text Mark on the Marks Shelf:
2) Now, remove the SUM aggregation from Total Expenses, and add a quick table calculation -> Percent of total:
3) Next, Select the States of New York, California and Washington -> And then click the paperclip icon:
We can see the answer already : 23.386% in the view above (even before grouping!)
4) Finally, we get the following view and our answer:
NEW QUESTION 39
Given a map, which of the following fields can be placed in Size,Shape,Detail,Color
- A. Region, Country, Profit, State
- B. Longitude, Country, State, Sales
- C. Sales, State, Country, Profit
- D. Profit, State, Number of Records, Sales
Answer: C
Explanation:
Explanation
Since Sales is a measure, it can easily be depicted via size.
To drill down and change the level of detail, Country is the correct choice since it will contain STATE. We can then depict the various states by different shapes such as circle, square etc.
Finally, the Profit can be depicted via a color! Eg - Red for poor and green for excellent profits!
NEW QUESTION 40
Which of the following is NOT a new feature introduced in Tableau 2020.1?
- A. Set Control
- B. Buffer Calculations
- C. Viz Animations
- D. Dynamic Paramaters
Answer: A
Explanation:
Explanation
Your Tableau Desktop Specialist exam will be based on the 2020.1 version.
Set controls are a new feature introduced in the 2020.2 version, and hence is the correct answer - it is not a part of 2020.1 For the 2020.1 version the new features were:
1) Viz animations:
Viz animations help you see and understand your changing data. It's easy to track the logical steps behind data's evolution and tell powerful data stories. Sorting, filtering, adding fields, and other actions will now smoothly animate your visualizations. Choose whether to turn Viz Animations on or off, and decide how you'd best like to apply animations to your new workbooks.
2) Dynamic Parameters:
Say goodbye to republishing workbooks with parameters every time the underlying data changes. Set your parameter once, and Tableau will automatically update the parameter's list of values every time someone opens the workbook.
3) Buffer Calculations:
Buffer calculations allow you to visualize the distance around point locations. Give Tableau three parameters-location, distance, and a unit of measure-and a buffer, or boundary is instantly created.
Answering complex spatial questions becomes easier than ever before-visualize what properties are within
200 meters of a proposed transit site, or how many competitors' stores are within 1 mile of their store, and more.

NEW QUESTION 42
Is SUM a table calculation?
- A. Yes
- B. No
Answer: B
Explanation:
Explanation
SUM is an aggregate function, not a table calculation!
A table calculation is a transformation you apply to the values in a visualization. Table calculations are a special type of calculated field that computes on the local data in Tableau. They are calculated based on what is currently in the visualization and do not consider any measures or dimensions that are filtered out of the visualization.
The most common Table calculations are:
Running Total
Percent Difference
Difference
Percent of Total
Rank
Percentile
These can be calculated using : Table(across), Cell, or Specific dimensions!
NEW QUESTION 43
Which of the following is a benefit of using a Tableau Data Source (.tds)?
- A. To hold one or more worksheets, plus zero or more dashboards and stories.
- B. To create a local copy of a subset or entire data set that you can use to share data with others, when you need to work offline, and improve performance.
- C. To 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 etc
- D. To create a single zip file that contains a workbook along with any supporting local file data and background images. This is great for sharing your work with others who don't have access to the original data.

3) (.twb) Workbooks - To hold one or more worksheets, plus zero or more dashboards and stories.
NEW QUESTION 44
True or False: Sets can be created on Measures
- A. True
- B. False
Answer: B
Explanation:
Explanation
Sets are custom fields that are created within Tableau Desktop based on dimensions from your data source.
They are subsets of your data, which can be created manually or computed. Either dimensions or measures can be used to determine what is included or excluded from a set using conditional logic, but to CREATE a set we use dimensions.

NEW QUESTION 46
Is it possible to add both a Dashboard and a Worksheet at the same time to a Story Point in Tableau?
- A. Yes
- B. No
Answer: B
Explanation:
Explanation
This is a tricky question. We are talking about story POINTS, and not entire stories in the question.
To create a story, lets say I have a blank story with 1 dashboard and 1 worksheet.
I can simply drag the dashboard into the view to create a new story point.
Now, if I try to adjust the worksheet beside it in this same view, I cannot. See below:
The only option available is to replace the existing view. Therefore, the answer is NO since they both cannot be added.

- A. 3.840
- B. 3.000
- C. 3.500

Since we need to focus on 1 country -> Japan, let's filter on it first as follows:
1) Drag Country to the filter shelf, and choose only Japan. Click OK.
2) Read the Question Carefully, we need to break down the visualisation by Region, then by Country, and then by State. So let's do that:
Drag Region to the column shelf, followed by Country. Drill down into Country to include states as well.
Then drag Quantity to the Row Shelf, and change the Aggregation to AVERAGE.
The following is our visualisation:
Now that you think of it, EVEN IF YOU REMOVE THE REGION, THE ANSWER REMAINS THE SAME.

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 54
If you see the following Filter, then you're working with _______________________ Larger image
- A. Date Parts
- B. Date Functions
- C. Date Values
- D. Grouped Dates
Answer: C
Explanation:
Explanation
Dates in Tableau will behave differently depending on whether they are a Datepart (blue) or a Datevalue (green). This affects how the axes display/behave and also how visualisations such as line charts will display.
The difference essentially boils down to Dateparts behaving like a dimension as opposed to a measure which is how Datevalues behave. This means that Dateparts behave like discrete categories on the view whereas Datevalues are more like continuous numeric values.
Dateparts are discrete and they behave the same as dimension filters. If all dates are used on the filter then each individual date will be a datepart that can be selected/excluded. This is the same for each level of date, if datepart months is placed on filters January to December will be tick-able options in the filter. This also means that conditions and top/bottom filters can be applied to datepart filters like any other dimension filter.
Datevalues placed on filters behave like measure filters. A min and a max date can be set and there is a relative dates option which allows you to choose things like only show the previous 3 months or years etc.

When working with Excel, text file data, JSON file, .pdf file data, you can also use this method to union files across folders, and worksheets across workbooks. Search is scoped to the selected connection. The connection and the tables available in a connection are shown on the left pane of the Data source page.
NEW QUESTION 57
Which of the following would you use to edit the Shape, colour, and Text of your visualisations?
- A. Filter Shelf
- B. Data Pane
- C. Marks Card
- D. Analytics Pane
Answer: C
Explanation:
Explanation
The Marks Card allows us not only to edit the Shape, Text and Colour, but also to modify the Tooltip and the level of detail of the visualisation!
The Marks card is a key element for visual analysis in Tableau. As you drag fields to different properties in the Marks card, you add context and detail to the marks in the view.
You use the Marks card to set the mark type (see Change the Type of Mark in the View), and to encode your data with color, size, shape, text, and detail. To change the mark settings, see Control the Appearance of Marks in the View.
In this example, three different fields have been dragged to different properties in the Marks card. Segment is on Color, Region is on Shape, and Quantity is on Size.
After you add a field to the Marks card, you can click the icon next to the field to change the property it is using. You can also click the property buttons in the Marks card to change those settings.
Many properties can have multiple fields. For example, you can add multiple fields to Label, Detail, Tooltip, and Color. Size and Shape can only have one field at a time. For more details, see Control the Appearance of Marks in the View.
