NEW QUESTION # 56
Which of the following is a compelling reason to export a sheet in Tableau to a PDF?
- A. If we want to dynamically enter parameters to the visualisation.
- B. If we want to interact with the visualisation.
- C. If we want a static view of the visualisation.
- D. If we want to use filters in the visualisation.
Answer: C
Explanation:
Exporting the visualisation gives us a static view of the visualisation.
It is NOT possible to interact with it, use filters, or dynamically enter anything in a visualisation exported PDF.
In Tableau Desktop, you can save views as PDF files rather than printing them as hard copies. You do not need to have Adobe Acrobat installed on your computer.
When you print an individual sheet to PDF, filters in the view are not included. To show filters, create a dashboard containing the sheet and export the dashboard to PDF. (IMPORTANT)
NEW QUESTION # 57
You need to uniformly change the size for all marks in a view.
What should you do?
- A. Select Label on the Marks card and then select Alignment.
- B. Select Format on the menu, and then select Cell Size.
- C. Select Size on the Marks card and use the slider to adjust the size
- D. Use the Fit dropdown menu on the toolbar.
Answer: C
Explanation:
You should select Size on the Marks card and use the slider to adjust the size to uniformly change the size for all marks in a view. The Size property on the Marks card allows you to control the size of marks in the view by moving the slider to the left or right. The Size slider affects different marks in different ways, such as making them bigger or smaller, wider or narrower, or thicker or thinner1 The other options are not valid ways to uniformly change the size for all marks in a view. Selecting Label on the Marks card and then selecting Alignment will allow you to change the position of labels on marks, not the size of marks2 Using the Fit dropdown menu on the toolbar will allow you to change how the view fits within the worksheet, not the size of marks3 Selecting Format on the menu, and then selecting Cell Size will allow you to change the height and width of cells in a text table, not the size of marks in other types of views4
NEW QUESTION # 58
Which of the following lets you group related dashboard items together so you can quickly position them?
- A. Layout positioners
- B. Layout Containers
- C. Layout Extensions
- D. Layout Blanks
Answer: B
Explanation:
Layout containers let you group related dashboard items together so you can quickly position them. As you change the size and placement of items inside a container, other container items automatically adjust

NEW QUESTION # 60
In which situation should you save a workbook as a PDF document?
- A. Your analysis does not require a live connection to a data source.
- B. Your users have Tableau Desktop but not Tableau Reader.
- C. You want document users to be able to filter and sort the views.
- D. You need paper copies of the workbook.
Answer: D
Explanation:
You should save a workbook as a PDF document if you need paper copies of the workbook. A PDF document preserves the layout and formatting of the workbook, and can be easily printed or shared. Saving a workbook as a PDF document is not necessary or useful in the other situations1
NEW QUESTION # 61
Which of the following is the correct way to calculate Profit Ratio in Tableau?
- A. SUM(Profit) / SUM(Sales)
- B. Profit / Sales
- C. Sales / Profit
- D. SUM(Sales)/SUM(Profit)
Answer: A
Explanation:
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!

NEW QUESTION # 64
Which of the following would you use to connect to multiple tables in a single data source at once?
- A. A Join
- B. A Hierarchy
- C. A Set
- D. A Blend
Answer: A
Explanation:
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 # 65
You have cleaned a data source properly, created some calculated fields and renamed some columns. You want to save these changes for future use cases. Which of the following would BEST satisfy this requirement?
- A. Save it as a .tds file
- B. Save it as a .twb file
- C. Save it as a .twm file
- D. Save it as a .twbx file
Answer: A
Explanation:
After making changes to Data, we can save that new data source as a .tds file. To do so, go to data menu on top and then choose your current connected data source. Then next click on Add to Saved Data sources. This will save all calculated fields, changes to fields etc. It will be saved in My Tableau Repository -> Mydatasources. This will then also appear on Tableau Home Page under saved data sources like SampleSuperStore.
Note: Data source files do 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, adding groups, and so on.
.twb and .twbx are not the BEST solutions since the questions nowhere mentions that we need to store our workbooks as well.
.twm is a bookmark which contains a single worksheet and are an easy way to quickly share your work.
NEW QUESTION # 66
Our use case states that we need to create a set showing the Bottom 10 products by Profit in each Region. Which of the following filter types should you apply on Region?
- A. Dimension Filters
- B. Measure Filters
- C. Extract Filters
- D. Context Filters
Answer: D
Explanation:
The beauty of context filters is that according to Tableau's Order of Operations, they are executed before Sets.
This means that based on what Region's you've selected - Tableau will first only preserve the rows for those Regions. THEN, after this it will compute the Set , i.e , Bottom 10 products in each Region.
1) First let's create a set to compute the Bottom 10 Products by Profit.
2) Next, take region on the Rows Shelf followed by the Set we just created. Drag Region and the Set to the Filters Shelf as well.
3) Now, try to only visualize the data for the South Region:
4) The problem right now is that Tableau is computing the Set first (Bottom 10 Products), and then applying the Dimension Filter - South Region and hence these values are incorrect. Note how these aren't even 10 products, but rather just 8. To fix this, simply add Region to Context:
Upon doing this, we get the correct answer as :

NEW QUESTION # 69
You can create _______________ for members in a dimension so that their labels appear differently in the view.
- A. parameters
- B. copies
- C. aliases
- D. duplicates
Answer: C
Explanation:
Explanation
You can create aliases (alternate names) for members in a dimension so that their labels appear differently in the view.
Aliases can be created for the members of discrete dimensions only. They cannot be created for continuous dimensions, dates, or measures.
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 # 70
What are three benefits of using an extract as compared to a live connection to a data source? Choose three.
- A. Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source.
- B. A live connection to a data source provides the best performance for data connections.
- C. A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance.
- D. An extract reduces the amount of data stored on a client computer as compared to a live data connection.
- E. Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections.
Answer: A,C,E
Explanation:
There are three benefits of using an extract as compared to a live connection to a data source:
A live connection to a data source can be slow due to network and user traffic, whereas a connection to an extract improves performance. An extract is a snapshot of data that is stored locally on your computer or on Tableau Server. An extract can reduce the load on the data source and speed up queries.
Extracts are stored in memory (RAM), resulting in faster query performance as compared with live data connections. When you use an extract, Tableau loads the data into memory and optimizes it for analysis. This allows Tableau to perform calculations and aggregations faster than with live connections.
Calculated fields perform better in workbooks connected to extracts than in workbooks with live connections to a data source. Calculated fields are custom fields that you create using formulas or expressions. When you use an extract, Tableau can process calculated fields more efficiently than with live connections.
