質問 # 132
Which of the following would you use to connect to multiple tables in a single data source at once?
- A. A Blend
- B. A Set
- C. A Join
- D. A Hierarchy
正解：C
解説：
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.
質問 # 133
Using the atheletes table:
i) Create a sheet with a crosstab showing the Average weight for each sport (Sheet 1) ii) Create a sheet with a Map showing the Total number of gold medals per Country. Use size as a Mark. (Sheet 2) Now, Create a Dashboard containing both these sheets, and Use Sheet 2 as a Filter for Sheet 1. What was the average weight for Badminton in Russia?
(Ignore any nulls / unknowns)
- A. 68.77
- B. 65.67
- C. 4.87
- D. 76.25
正解：D
解説：
Pretty common question on the Tableau Desktop Specialist exam.
1) First, lets create Sheet 1. For this, drag sport to the Row shelf, and Weight to the Text mark in the Marks shelf. Change its aggregation to Average:
2) Now, for sheet 2 - Drag nationality to the view, and gold to the size mark in the Marks shelf.
NOTE: Depending on your version of Tableau , you may need to assign a Geographical role to the nationality column first as follows:
3) Now, let's create a dashboard, and use both these sheets in it:
4) Now, for the most Important step, use SHEET 2 AS A FILTER FOR SHEET 1 as follows:
Now simply click on Russia in Sheet 2, and Sheet 1 will automatically update as follows:
質問 # 134
True or False: When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, then relating these tables is not possible.
- A. True
- B. False
正解：B
解説：
Graphical user interface, application Description automatically generated
Tables that you drag to the logical layer of the Data Source page canvas must be related to each other. When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, you will need to select them.
If no constraints are detected, a Many-to-many relationship is created and referential integrity is set to Some records match. These default settings are a safe choice and provide the most a lot of flexibility for your data source.
質問 # 135
Yes or No: The number of marks will increase when you increase the number of Dimensions in a view
- A. No
- B. Yes
正解：B
解説：
Of course! As an example, see below:
1) Using the Sample Superstore data, let's plot a bar chart showing the Sales for each Category:
Observe that we have 3 marks - Each bar in a bar chart is called a mark. Similarly, each point in a scatter plot is also a mark , and so on for all charts.
1 row by 3 columns means that clearly on the y-axis (Sales), we have only a single mark - a single continous axis, but 3 different marks (Technology, Furniture and Office supplies ) on the x-axis.
2) Now let's add subcategory to the view as well (another dimension):
Observe that the number of marks has increased - i.e the number of Bars.
Also, notice we now have 1 row and 17 columns. Simply because 1 row = Sales (on the y-axis), and on the x-axis, we have 17 different columns (i.e product sub categories!!)

質問 # 137
Which of the following options best describe measures?
- A. They are numerical, qualitative
- B. They are categorical, quantitative
- C. They are numerical, quantitative
- D. They are categorical, qualitative
正解：C
解説：
Data fields are made from the columns in your data source. Each field is automatically assigned a data type (such as integer, string, date), and a role: Discrete Dimension or Continuous Measure (more common), or Continuous Dimension or Discrete Measure (less common).
Dimensions contain qualitative values (such as names, dates, or geographical data). You can use dimensions to categorize, segment, and reveal the details in your data. Dimensions affect the level of detail in the view.
Measures contain numeric, quantitative values that you can measure. Measures can be aggregated. When you drag a measure into the view, Tableau applies an aggregation to that measure (by default).
質問 # 138
What is the one critical difference between normal calculated fields, and the calculated fields created after Data blending?
- A. Fields used in Blends must first be aggregated
- B. The calculated fields created in Blends cannot be edited once created
- C. The calculated fields created in Blends cannot use more than 2 fields
- D. No difference, calculated fields cannot be created in Blends
正解：A
解説：
Yes, due to the nature of blends, there are some conditions as follows from the official documentation that must be kept in mind while working with blends:
In addition to handling calculations slightly differently, there are some limitations on secondary data sources. You may not be able to sort by a field from a secondary data source, and action filters may not work as expected with blended data. For more information, see Other data blending issues.
質問 # 139
Which of the following are valid ways to show Mark Labels in the visualisation?
- A. Click on the Show mark labels icon in the Toolbar
- B. Click on Data in the Menu bar and Choose Show Mark Labels
- C. Click on Analysis in the Menu bar and choose Show Mark Labels
- D. Drag the measure to the Text label in the Marks Card
正解：A、C、D
解説：
The following showcase how you can show mark labels. Using the Sample Superstore dataset:
1) Let's create a Bar chart showing the sales for each sub-category:
2) Now you can show labels by:
2.1) Click on Show Mark Labels Icon in the Toolbar ( easiest )
2.2) Drag Sales to the Text icon in the Marks Card:
2.3) Click on Analysis -> Show mark labels from the Tableau menu bar:

True or False: When you drag additional tables to the logical layer canvas, Tableau automatically attempts to create the relationship based on existing key constraints and matching fields to define the relationship. If it can't determine the matching fields, then relating these tables is not possible.

質問 # 141
If you are working with a huge dataset, which of the following are strong reasons to use a context filter?
- A. To help clean the data
- B. Improve query performance
- C. To include only the data of interest
- D. To make the context filter a dependent filter
正解：B、C
解説：
By default, all filters that you set in Tableau are computed independently. That is, each filter accesses all rows in your data source without regard to other filters. However, you can set one or more categorical filters as context filters for the view. You can think of a context filter as being an independent filter (Option stating - To create a dependent filter eliminated here). Any other filters that you set are defined as dependent filters because they process only the data that passes through the context filter.
You may create a context filter to:
1) Improve performance - If you set a lot of filters or have a large data source, the queries can be slow. You can set one or more context filters to improve performance.
2) Create a dependent numerical or top N filter - You can set a context filter to include only the data of interest, and then set a numerical or a top N filter.
For example, suppose you're in charge of breakfast products for a large grocery chain. Your task is to find the top 10 breakfast products by profitability for all stores. If the data source is very large, you can set a context filter to include only breakfast products. Then you can create a top 10 filter by profit as a dependent filter, which would process only the data that passes through the context filter.

質問 # 143
Which of the following are valid ways of Grouping Data?
- A. Using Marks in the view
- B. From the Analytics Pane
- C. Using Labels in the View
- D. From the Dimensions Shelf
正解：A、C、D
解説：
**IMPORTANT QUESTION AND , 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 # 144
Which of the following is the correct way to calculate Profit Ratio in Tableau?
- A. SUM(Sales)/SUM(Profit)
- B. Profit / Sales
- C. SUM(Profit) / SUM(Sales)
- D. Sales / Profit
正解：C
解説：
Explanation
THIS IS A VERY IMPORTANT QUESTION
Aggregation is an important concept to consider when creating calculated fields. A calculated field for SUM([Profit]) / SUM([Sales]) will give you a very different answer than [Profit] / [Sales], even though both formulas are valid.
If you do not provide the aggregation within the calculated field, Tableau will calculate the equation for every record ( row ) in your analysis, then aggregate the answers for all of the rows together when the calculated field is added to the view.
In simple terms, if specify the aggregation such as SUM, what Tableau will do is that it will first calculate the sum of the Profit column ( say x ), then calculate the sum of the Sales column ( say y ), and then simply apply x/y ---> This is what we expect! Perfect!
BUT, if you don't specify the aggregation, it will go to every single ROW, perform Profit / Sales, and then aggregate the answers calculated for each row. This is simply NOT what we wan't!
An example:
質問 # 145
DOWNLOAD THE DATASET FROM - https://drive.google.com/file/d/1F8L_Rl5B9LAz8RDi-DdjWx3Iv-SgzaBq/view?usp=sharing ( if you haven't already from the test instructions page! ) How many different countries are present in the dataset?
- A. 0
- B. 1
- C. 2
- D. 3
正解：D
解説：
To reach the correct answer, follow these steps:
1) You can simply drag Country to the view, and look at the marks in the bottom left of Tableau Desktop - 147 marks!
2) Or, you can simply go to Data Source -> Country Tab -> Describe
As you can see, 147 members exist in this Country column!
質問 # 146
Which three statements accurately describe dimensions? Choose three.
- A. Affect the level of detail in the view
- B. Contain qualitative values
- C. Affect the formatting options in the view
- D. Contain numeric, quantitative values
- E. Can be continuous or discrete
正解：A、B、C
解説：
Three statements that accurately describe dimensions are: Contain qualitative values Affect the level of detail in the view Can be continuous or discrete Dimensions are fields that contain qualitative values, such as names, dates, or geographical data. You can use dimensions to categorize, segment, and reveal the details in your data.
Dimensions affect the level of detail in the view by creating headers or labels for marks or by defining how data is partitioned for table calculations. Dimensions can be continuous or discrete depending on their data type and format. Continuous dimensions are those that have an infinite range of possible values, such as numbers or ratios. Discrete dimensions are those that have a finite number of distinct values, such as names, categories, or dates3 The other options are not accurate statements about dimensions. Contain numeric, quantitative values is not correct, because fields that contain numeric, quantitative values are measures, not dimensions. Measures are fields that contain numeric values that you can measure and aggregate. Affect the formatting options in the view is not correct, because formatting options are not determined by dimensions, but rather by user preferences and choices. Formatting options allow you to change the appearance of various elements in the workbook, such as fonts, borders, shading, alignment, etc3
質問 # 147
Which two functionalities can you provide to consumers by adding a parameter to a visualization? Choose two.
- A. Change fields in the visualization.
- B. Create a new field in the data source.
- C. Change the results of calculations in the visualization.
- D. Download the underlying data as a CSV file.
正解：A、C
解説：
In Tableau, parameters are dynamic values that can replace a constant in calculations, filters, and reference lines. If you have a parameter controlling a calculation, changing the parameter value can change the results of that calculation, thus impacting the visualization. Parameters can also be used to switch between different fields in the visualization; for example, allowing users to choose which measure or dimension to display.
質問 # 148
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 : 14 marks
- B. If dragged to row shelf : 14 marks ; If dragged to column shelf : 14 marks
- C. If dragged to row shelf : 7 marks ; If dragged to column shelf : 7 marks
- D. If dragged to row shelf : 14 marks ; If dragged to column shelf : 7
marks
正解：D
解説：
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!
