質問 # 50
You have the following box plot that shows the distribution of average profits made in every state by region.

Which region has the smallest distribution of profits?

  • A. Cast
  • B. South
  • C. Central
  • D. West

正解：C

解説：
The central region has the smallest distribution of profits because it has the smallest interquartile range (IQR), which is the distance between the first and third quartiles of the box plot. The IQR measures the spread of the middle 50% of the data. The smaller the IQR, the less variation in the data.

質問 # 59
You are developing a data source in Tableau Prep.
You have two tables named Orders and Employees.
The Orders table was created in 2019 and contains the following columns.

The Employees table contains all the employee information for the various sales teams in the sales department and contains the following columns

You want to prepare the data so that you can analyze sales trends over time for every sales team.
Which three actions should you perform in order? (Place the three correct options in order. Use the arrows to move Options to Answer Area. Use Answer Area arrows to re-order the options.)

正解：

解説：

Explanation:

There are different ways to prepare the data in Tableau Prep, but one possible answer is:
Answer area:
Join the tables.
Aggregate the data by Sales Team.
Add the following filter to the Employees table: Sale Team - Team Alpha.
To analyze sales trends over time for every sales team, you need to combine the data from the Orders and Employees tables. You can do this by joining the tables on the Rep ID column, which is a common identifier for both tables. This will create a single table with all the columns from both tables. Next, you need to aggregate the data by Sales Team, which is the level of analysis you want. You can do this by grouping the data by the Sales Team column and applying an aggregation function (such as sum, average, count, etc.) to the other columns that you want to measure (such as Total Amount, Rep Tenure, etc.). This will create a summary table with one row for each sales team and the aggregated values for the other columns. Finally, you need to filter the data to focus on a specific sales team, such as Team Alpha. You can do this by adding a filter to the Employees table and selecting only the rows where Sales Team equals Team Alpha. This will remove the rows for other sales teams and keep only the data for Team Alpha.

質問 # 62
A colleague provides you with access to a folder that contains the following files:
* Sates.csv
* Bookl.twb
* Sates.hyper
* Export.mdb
Which He contains an extract?

  • A. Book1.twb
  • B. Export mdb
  • C. Sales.hyper
  • D. Sales.csv

正解：C

解説：
A .hyper file is an extract file that contains a snapshot of data from a data source. It is a compressed and optimized file format that can be used to improve the performance and portability of dashboards and workbooks. A .twb file is a workbook file that contains the visualization and connection information, but not the data itself. A .csv file is a comma-separated values file that contains plain text data. A .mdb file is a Microsoft Access database file that contains tables, queries, forms, and other objects. References:

https://support.microsoft.com/en-us/office/introduction-to-access-database-files-9f9a0f8c-9a3c-4a0b-8e6c-6d1f1
In Tableau, a .hyper file is an extract file created by the Hyper database engine.
It contains a snapshot of the data pulled into Tableau and is used to perform data analysis without the need for a live connection to the data source.


質問 # 63
You have the following primary data source that contains a dimension named Dorm_Code.

You receive the following secondary data source that contains updated dorm codes.

You need to bring the updated dorm codes into Tableau and use the codes in existing visualizations. The new dorm codes must use the existing field name of Dorm_Code.
What should you do?

  • A. Bring in the secondary data source as a union.
  • B. Create a data blend and select Edit Primary Aliases to replace the primary data source alias values with values from the secondary data source
  • C. Bring in the secondary data source by using relationships. From the Data pane, right-click Dorm_Name select Replace References, and then select Dorm_Name_New
  • D. Bring in the secondary table as a left join to the primary data source. From the Data Source page, select Create Calculated Field in the Dorm_Name field and enter [Dcrm_Name_New] in the calculation window

正解：C

解説：
Using relationships: You can use relationships to link the secondary data source with the primary data source based on a common field. This will allow you to use fields from both data sources in your visualization without creating new fields or duplicating data. You can then replace references to update the dimension values. For example, you can use relationships to link the updated dorm codes with the primary data source and then replace Dorm_Code with Dorm_Code_New in your visualization.
https://community.tableau.com/s/question/0D54T00000C5ldZSAR/update-data-view-based-on-dimension To update existing visualizations with new codes without changing the field name, using relationships to bring in the secondary data source is appropriate. Then using Replace References allows you to update the references from the old dorm codes to the new ones while maintaining the existing field name.


質問 # 64
You have a database that includes field named sales, City and Region.
You have the following chart that shows the number of sales made in different cities.

You want to dynamically show the corresponding region when users hover their mouse over any of the bars.

  • B. Right-click a in the chat, select Annotate and then select Mark.
  • C. Drag Region to Tooltip on the Marks card
  • D. Edit the aliases for City.

正解：C

解説：
To show the corresponding region when users hover their mouse over any of the bars, you need to drag Region to Tooltip on the Marks card. This will add Region as a field in the tooltip text that appears when users hover over a mark. You can also customize the tooltip text by editing it in the Tooltip dialog box. Reference: https://help.tableau.com/current/pro/desktop/en-us/buildmanual_shelves.htm https://help.tableau.com/current/pro/desktop/en-us/formatting_tooltips.htm

You have the following calculated fields in a worksheet.
[Calc1] = DATEADD ('year', -1, TODAY ())
[Calc2] = DATETRUNC ( 'month' , DATEADD ('year', -1, TODAY ())
You want to calculate the month to date value of the prior year.
How should you complete the formula? (Drag the appropriate Options to the Answer Area and drop into the correct locations.)

正解：

解説：

Explanation:
A screenshot of a computer Description automatically generated

To calculate the month to date value of the prior year, you need to filter the order date to be between the first day of the same month of the previous year and the same day of the previous year. You can use the calculated fields [Calc1] and [Calc2] to get these dates. [Calc1] returns the date that is one year before today, and [Calc2] returns the date that is the first day of the month of [Calc1]. By using these fields in the filter condition, you can get the desired result.

Which function should you use to remove the semicolons from the Name field?

  • A. TRIM
  • B. SPLIT
  • C. REPLACE
  • D. CONTAINS

正解：C

解説：
The REPLACE function is used to replace all occurrences of a substring within a string with another substring.
In this case, it can be used to remove the semicolons from the Name field by replacing them with an empty string. For example, REPLACE ("John;Doe", ";", "") = "JohnDoe". References: The information is based on the following sources:

質問 # 69
You want to create the following dashboard.

The dashboard will contain two sheets that will connect to the same data source. The top sheet will be configured to filter the bottom sheet.
When you click a category on the top sheet, the sheets must resize as shown in the following exhibit.

How should you lay out the objects on the dashboard?

  • A. Drag a horizontal container to the dashboard and add both sheets to the container. Set the Fit to Standard.
  • B. Drag a vertical container to the dashboard and add both sheets to the container. Set Fit to Entire view.
  • C. Add both sheets to the dashboard. Set Fit to Fix width.
  • D. Drag a blank object to the dashboard and add both sheets to the dashboard. Set Fit to Entire view.

正解：B

解説：
To create the dashboard as shown in the image, you need to use a vertical layout container that will adjust the height of the sheets according to the window size. You also need to set the Fit to Entire view option for both sheets so that they will resize proportionally when you click a category on the top sheet. This way, you can achieve the desired effect of having the bottom sheet expand to fill the space left by the top sheet when it filters out some categories. Reference:
