NEW QUESTION # 82
You have the following dataset.
Which grouping option should you use m Tableau Prep to group al five names automatically?
- A. Pronunciation
- B. Common Characters
- C. Manual Selection
- D. Spelling
Answer: C
Explanation:
To group all five names automatically, you should use Manual Selection as a grouping option in Tableau Prep. Manual Selection is a feature that allows you to select values from your data and group them together based on your criteria. You can use Manual Selection by clicking on Group Values in Profile pane > Manual Selection from the menu. This will open a dialog box where you can select values from your data and assign them to a group.
In this case, you want to group all five names together based on their spelling variations. You can use Manual Selection by selecting all five values from your data and assigning them to a group named "Harry Potter". This will create a new field named Grouped Field that contains "Harry Potter" as one value.
The other options are not correct for this scenario. Pronunciation is a feature that groups values based on how they sound, but it may not work well with names or uncommon words. Spelling is a feature that groups values based on common spelling errors or typos, but it may not recognize all variations or synonyms. Common Characters is a feature that groups values based on the number of characters they share, but it may not capture the meaning or context of the values.

Answer:
Explanation:
NEW QUESTION # 87
You have the following two datasets:
* A Microsoft Excel worksheet that has two columns named Employee Name and Department
* A Microsoft SQL Server table that has three columns named Employee Name. Pay Grade and Team Size.
You want to use Tableau Prep to join the two datasets.
Which three actions should you perform in order? (Place the three correct options in order.)
Answer:
Explanation:
The correct order of the three actions is:
* From the connections pane, connect to both data sources
* Join both datasets and select the join type
* Specify Employee Name as the join key
The first action is to connect to both data sources from the connections pane in Tableau Prep. The connections pane is where you can access and add data sources to your flow. You can connect to various types of data sources, such as Excel, SQL Server, or Tableau Server. In this case, you want to connect to an Excel worksheet and a SQL Server table.
The second action is to join both datasets and select the join type. A join is a way of combining data from two or more tables based on a common field. You can join datasets by dragging one table to the canvas and dropping it on top of another table. This will create a join step in your flow. You can select the join type from the drop-down list on the join step. The join type determines which rows are returned from the tables.
The third action is to specify Employee Name as the join key. A join key is a field that is used to match rows from different tables. You can specify the join key by clicking on the field name in each table and dragging it to the center of the join step. This will create a join clause that shows the field name and the operator. In this case, you want to use Employee Name as the join key, because it is a common field between the two datasets.
The other options are not relevant for this scenario. Specifying Department and Team Size as a join condition will not work, because they are not common fields between the two datasets. Opening both data sources in Tableau Desktop will not help you join them in Tableau Prep. Adding a step to aggregate the data in the SQL Server table will not affect the join, but it may change the level of detail of your data. References: https://help.

NEW QUESTION # 88
You have the following table.
You need each record to alternate between grey and white.
What should you change in the Format Shading pane?
- A. the row banding size to 1
- B. the column banding size to 3
- C. the column banding size to 1
- D. the row banding size to 3
Answer: A
Explanation:
To have each record alternate between grey and white, you should change the row banding size to 1 in the Format Shading pane. This setting will ensure that each row has a different shading from the one above and below it, creating an alternating pattern of grey and white rows. References: The answer can be verified through practical application within Tableau or by consulting Tableau's official learning resources, such as Tableau Help: Format Shading or Tableau Training Pass: Formatting.

NEW QUESTION # 90
You plan to create a visualization that has a dual axis chart. The dual axis chart will contain a shape chart and a line chart will use the same measure named Population on the axis.
You need to configure be shapes to be much larger than the line.
What should you do?
- A. Change Population to a discrete dimension
- B. Duplicate Population Drag the duplicate to the second Marks card and configure the see of the marks independently
- C. For the second axis select Shape on the Marks card From Select Shape Palette select Custom and then select Reset
- D. Create a custom shape that is larger than the default shape and add the shape to the Shapes folder in My Repository
Answer: B
Explanation:
To configure the shapes to be much larger than the line, you need to duplicate Population and drag it to the second Marks card. This will create a dual axis chart with two measures on one axis. You can then select Shape on one Marks card and Line on another Marks card, and adjust the size of each mark independently using the Size slider or menu. Reference: https://help.tableau.com/current/pro/desktop/en-us/multiplemeasures_dualaxes.htm https://help.tableau.com/current/pro/desktop/en-us/marks_markproperties_size.htm
NEW QUESTION # 91
You have the following map.
You need the map to appear as shown in the following visualization.
What should you do?
- A. Drag Population to Size on the Marks card
- B. Drag Location to Size on the Marks card
- C. Change the mark type to Density
- D. Change the opacity to 75%
- E. Change the mark type to Map
Answer: C
Explanation:
The question presents a scenario where a geographic map visualization in Tableau needs to be transformed from a series of discrete circles representing data points to a density map visualization. The density map shows concentrations of data points with a gradient of color, where denser areas are indicated by a darker color.
Here's the explanation for each option:
A). Change the mark type to Density: This is the correct answer because changing the mark type to 'Density' in Tableau creates a density map, which displays the concentration of data points with a color gradient. This is exactly what is needed to achieve the visual effect shown in the second image, where regions with a higher concentration of data points are represented by darker shades.
B). Drag Location to Size on the Marks card: This option would adjust the size of the marks based on the number of locations, which is not relevant to creating a density map. It would result in varying sizes of circles, not a continuous gradient.
C). Change the mark type to Map: The visualization is already using a map. This option would not change the visualization to the desired density map.
D). Drag Population to Size on the Marks card: This would change the size of the circles based on the population values, making some circles larger and others smaller. This is not how a density map is created, which uses color intensity rather than size to show concentration.
E). Change the opacity to 75%: Changing the opacity would affect the transparency of the marks on the map but would not transform the visualization into a density map.
To achieve the visualization shown in the second image, the mark type must be changed to 'Density,' which will produce a heat map-like effect where the color intensity represents the concentration of data points.
Therefore, the correct answer is A. Change the mark type to Density.
To create a density map from a scatter plot of data points, you would change the mark type to Density. This mark type allows you to visualize the concentration of data points in an area, which can be useful for identifying clusters or patterns in geospatial data.
NEW QUESTION # 92
You have the following dataset.
When you use the dataset in a worksheet, you want Sales to appear automatically as shown in the following table.
What should you do?
- A. Create a calculated field that uses a formula of 'S' * str (Round((sales],2)) + 'k'
- B. Change the data type of the Sates field to Siring
- C. Change the default number format of the Sales told
- D. Create a calculated field that uses a formula of 'S' + stri < (Sales)/1000)).
Answer: B
NEW QUESTION # 93
You have the following dataset that contain null values in the Profits field.
You want the data to appear as shown in the following table.
Which two formulas achieve the goal? Choose two.
- A. ZN ([Profits])
- B. IF [Profits] != null then [Profits] END
- C. IFNULL [(profits] ,0)
- D. ISNULL ([Profits])
Answer: A,C
Explanation:
Both the ZN and IFNULL functions in Tableau can be used to replace NULL values with zeros. The ZN function converts NULL to zero directly, while the IFNULL function allows you to specify that NULL should be replaced with zero. Both will result in showing zero for any NULL values in the Profits field.
