NEW QUESTION # 84
True or False: Physical tables remain distinct (normalized), not merged in the data source whereas logical tables are merged into a single, flat table.
- A. True
- B. False
Answer: B
Explanation:
In fact, the opposite of this is true.
Trick : Whenever you think of joins -> Think that after the join is created, we get 1 single flat combined (joined) table. This flat combined table is created prior to us creating our visualizations. This happens at the physical layer.
If you ever think about relationships, know that all tables will remain distinct and separate, and relationships sit at the logical layer. At run time, when you bring in the dimensions and measures to create your viz, Tableau very smartly creates the necessary joins, relates the tables and sends queries to these tables to get the resultant data back in the most meaningful way possible. This allows you to focus on using your data and revealing insights from it and focus less on the data preparation aspect!
Refer to logical layer vs physical layer from the official
documentation: https://help.tableau.com/current/server/en-us/datasource_datamodel.htm
NEW QUESTION # 85
In an extract, what are three differences between a full refresh versus an incremental refresh? Choose three.
- A. A full refresh replaces all the extracted data with the data in the underlying data source.
- B. An incremental refresh only adds rows that are new
- C. An incremental refresh can only be run from Tableau Server.
- D. A full refresh must be configured. An incremental refresh is the default extract in Tableau.
- E. A full refresh is usually very slow. An incremental refresh can take less time.
Answer: A,B,E
Explanation:
According to the [Tableau Desktop Specialist Exam Guide], an incremental refresh only adds rows that are new, based on a specified column and value. A full refresh replaces all the extracted data with the data in the underlying data source. A full refresh is usually very slow, especially for large extracts. An incremental refresh can take less time, depending on how many new rows are added. A full refresh does not need to be configured, it is the default option for extracts in Tableau. An incremental refresh can be run from both Tableau Desktop and Tableau Server.

NEW QUESTION # 87
Which statement accurately describes aliases?
- A. You can create an alias for a discrete measure.
- B. When you assign an alias, the name changes in the database.
- C. You can create an alias for a continuous dimension.
- D. You can assign an alias to a field member before creating a visualization.
Answer: D
Explanation:
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
NEW QUESTION # 88
You create the following visualization.
What is the first step to create the visual grouping of the 10 marks shown in blue?

- B. Select the desired 10 marks in the view.
- C. Create a Group on the Property Description field in the Data pane.
- D. Select the desired 10 text labels under Property Description.
Answer: B
Explanation:
To visually group marks in Tableau, you typically start by selecting the marks directly in the view. Once the desired marks are selected, you can then create a group from them. This will visually group the selected marks, as indicated by the blue color in the example provided.
NEW QUESTION # 89
You can create _______________ for members in a dimension so that their labels appear differently in the view.
- A. aliases
- B. parameters
- C. duplicates
- D. copies
Answer: A
Explanation:

To create an alias:
1) In the Data pane, right-click a dimension and select Aliases.
2) In the Edit Aliases dialog box, under Value (Alias), select a member and enter a new name.
To submit your changes: In Tableau Desktop, click OK.
On Tableau Server or Tableau Online, click the X icon in the top-right corner of the dialog box.
When you add the field to the view, the alias names appear as labels in the view. For example:

NEW QUESTION # 93
Which of the following is NOT a new feature introduced in Tableau 2020.1?
- A. Viz Animations
- B. Set Control
- C. Buffer Calculations
- D. Dynamic Paramaters
Answer: B
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 # 94
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. 27.73%
- B. 23.39%
- C. 29.49%
- D. 25.79%
Answer: A
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 # 95
Which of the following are stored in a .tds file? Choose 3.
- A. Data Connection information
- B. Data Extracts
- C. Calculated Fields
- D. Metadata edits
- E. Visualizations
Answer: A,C,D
Explanation:
If you've created a data connection that you might want to use with other workbooks or share with colleagues, you can export (save) the data source to a file. You might want to do this also if you've added joined tables, default properties, or custom fields-such as groups, sets, calculated fields, and binned fields-to the Data pane.
Visualisations and Data extracts are NOT saved in a .tds file!
NEW QUESTION # 96
For creating variable sized bins we use __________________
- A. Table Calculations
- B. Calculated Fields
- C. Groups
- D. Sets
Answer: B
Explanation:
One way to view a measure in Tableau Desktop is to split it into bins. You can think of bins as buckets based on a range of values. For example, say you have a measure that represents age. Instead of aggregating the measure to calculate the average age, you can bin the measure to define age groups: 0-5, 6-10, 11-15, and so on. Then you can count the number of people in each age group.
Create a calculated field for variable bin size
Step 1
Select Analysis > Create Calculated Field.
Step 2
In the Calculated Field dialog box, complete the following steps:
NEW QUESTION # 97

It is clear that October with -55.3% had the lowest Year on Year growth.
NEW QUESTION # 98
Which of the following is NOT a valid official data source in Tableau Desktop?
- A. Google Firebase
- B. SAP HANA
- C. PostgreSQL
- D. Amazon Redshift
Answer: D
Explanation:
Explanation
Presently, there is no official way to connect your data in Firebase directly with Tableau Desktop.
A workaround however can be to export your Firebase data into Google BigQuery, and then connect it to Tableau Desktop.
But then again, it is a workaround and not an official out-of-the-box solution.
The following are the available Data sources available as of now:
* Server
* File
