質問 # 135
For which of the following charts, does the Size option on the Marks card not work?
- A. Bar Chart
- B. Tree Map
- C. Gantt Chart
- D. Pie Chart
正解：B
解説：
You can adjust the size for all charts except the Tree Map. You use dimensions to define the structure of the treemap, and measures to define the size or color of the individual rectangles. Treemaps are a relatively simple data visualization that can provide insight in a visually attractive format.
In a Tree Map, the measure itself defines the size and colour! The greater the sum of Measure for each category, the darker and larger its box.
質問 # 136
Which chart type uses automatically generated sizes that cannot be resized by using the Marks card?
- A. Histograms
- B. Pie charts
- C. Treemaps
- D. Area charts
正解：C
解説：
Treemaps use automatically generated sizes that cannot be resized by using the Marks card. A treemap is a type of visualization that shows hierarchical data as a set of nested rectangles. Each rectangle represents a dimension member and its size is proportional to a measure value. Tableau automatically calculates the size of each rectangle based on an optimal aspect ratio for readability and comparison. You cannot manually adjust the size of each rectangle by using the Marks card or any other option in Tableau10 The other chart types do not use automatically generated sizes that cannot be resized by using the Marks card. Pie charts use angles to show proportions of a whole, not sizes. Histograms use bins and frequencies to show distributions of a measure, not sizes. Area charts use filled areas to show trends over time or categories, not sizes. You can adjust the size of these chart types by using the Marks card or other options in Tableau
質問 # 137
How do you identify a continuous field in Tableau?
- A. It is preceded by a '=#' symbol in the data window
- B. It is identified by a blue pill in the visualization
- C. It is identified by a green pill in a visualization
- D. It is preceded by a 'Abc' symbol in the data window
正解：A
解説：
When you connect to a new data source, Tableau assigns each field in the data source as dimension or measure in the Data pane, depending on the type of data the field contains. You use these fields to build views of your data.
質問 # 138
Are animations enabled by default in Tableau?
- A. No
- B. Yes
正解：A
解説：
Explanation
No, by default, animations are not enabled in Tableau.
We can animate visualizations to better highlight changing patterns in your data, reveal spikes and outliers, and see how data points cluster and separate.
Animations visually transition between filter, sort, and zoom settings, different pages, and changes to filter, parameter, and set actions. As visualizations animate in response to these changes, viewers can more clearly see how data differs, helping them make better informed decisions.
When you author animations, you can choose between two different styles: simultaneous or sequential. Here are examples of each type.
1) Simultaneous animations
The default simultaneous animations are faster and work well when showing value changes in simpler charts and dashboards.
2) Sequential animations
Sequential animations take more time but make complex changes clearer by presenting them step-by-step.
To Animate visualizations in a workbook:
1) Choose Format > Animations.
2) If you want to animate every sheet, under Workbook Default, click On. Then do the following:
For Duration, choose a preset, or specify a custom duration of up to 10 seconds.
For Style, choose Simultaneous to play all animations at once or Sequential to fade out marks, move and sort them, and then fade them in.
3) To override workbook defaults for a particular sheet, change the settings under Selected Sheet.
質問 # 139
When using Animations in a Tableau, which of the following is the default duration for animations?
- A. 0.2s
- B. 0.5s
- C. 0.3s
- D. 0.4s
正解：C
解説：
Explanation
The LATEST Tableau Desktop Sepcialist exam blueprint now requires you to know some basics about animations as well!
NOTE: Animations are DISABLED by default and must be manually enabled.
You can also reset all settings to default by clickin on 'Reset All'

True or False: A sheet cannot be used within a story directly. Either sheets should be used within a dashboard, or a dashboard should be used within a story.
- A. rue
- B. False
正解：B
解説：
Explanation
It is possible in Tableau to use a sheet within a story directly.
Moreover, in Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case.
At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet in a story is called a story point.

Which of the following are valid ways of Grouping Data?
- A. From the Analytics Pane
- B. Using Marks in the view
- C. Using Labels in the View
- D. From the Dimensions Shelf
正解：B、C、D
解説：
**IMPORTANT QUESTION AND EXPLANATION, PLEASE READ**
3 ways to group data -
1) Marks
2) Labels
3) Dimensions shelf.
*IMPORTANT*
If we Group the data by selecting the marks, then they remain separate marks in the view and then have the same colour. Also, a new group is created in the Dimensions shelf. Example - Using the sample superstore dataset, first plot a bar chart showing sales for each sub-category:
Here, if we Select Phones, Chairs and Storage by selecting the MARKS (Bars), and then group them:
They remain seperate marks (BARS) but are grouped by the same colour.
Now, if we didn't do this, and rather grouped by selecting their Labels (Names):
Then they no longer remain separate Marks (bars) but are rather consolidated into a single Bar:
Finally, we can group directly from the Dimensions shelf as follows:
Now choose Phones, Chairs and Storage and Click Group:
You will now automatically have a new Dimension as follows:
質問 # 153
When using the manage metadata option, we can create custom names for columns where _____________ is the original name of the column whereas _____________ is the custom name we created in Tableau.

- D. Local Name, Actual Name
正解：B
解説：
Explanation
Using the Sample superstore as a reference, click on the manage metadata icon as follows:
We can rename a particular column name to make it easier to remember and use in Tableau. Let's change Order ID to oID as shown:
Now, we'll see oID when using this data source in Tableau. This WILL NOT affect the original data source.
The remote field name let's us see what the name of the column is in the ORIGINAL Data source.

質問 # 156
Which statement accurately describes aliases?
- A. You can create an alias for a continuous dimension.
- B. When you assign an alias, the name changes in the database.
- C. You can create an alias for a discrete measure.
- D. You can assign an alias to a field member before creating a visualization.
正解：D
解説：
You can assign an alias to a field member before creating a visualization. An alias is an alternative name that you can assign to a value in a dimension field. You can use aliases to rename specific values within a dimension to make them more relevant or descriptive in your view than what the original data provides. For example, you can use aliases to shorten long names, correct spelling errors, or replace codes with meaningful labels6 You can create aliases for the members of discrete dimensions only. They cannot be created for continuous dimensions, dates, or measures. To create an alias for a dimension member, you can right-click the dimension in the Data pane and select Aliases, then enter a new name for each member under Value (Alias). You can also create an alias by right-clicking a dimension member in the view and selecting Edit Alias. You can do this before or after creating a visualization6 The other options are not accurate statements about aliases. You cannot create an alias for a discrete measure, because measures are not discrete fields. You cannot create an alias for a continuous dimension, because aliases are only available for discrete dimensions. When you assign an alias, the name does not change in the database, only in Tableau. Aliases are stored as part of the workbook or data source, and do not affect the original data6
質問 # 157
True or False: A sheet cannot be used within a story directly. Either sheets should be used within a dashboard, or a dashboard should be used within a story.
- A. rue
- B. False
正解：B
解説：
Explanation
It is possible in Tableau to use a sheet within a story directly.
Moreover, in Tableau, a story is a sequence of visualizations that work together to convey information. You can create stories to tell a data narrative, provide context, demonstrate how decisions relate to outcomes, or to simply make a compelling case.
At the same time, a story is also a collection of sheets, arranged in a sequence. Each individual sheet in a story is called a story point.
