質問 # 23
You create a parameter named Choose Region fiat contains values from a field named Region.
You want users to be able to use the Choose Region parameter to interact with a chart by logging between different regions What should you do next?
- A. Set the Choose Region parameter to Single Value (list)
- B. Add Region to me Fitters card
- C. Add the [Region] = [choose Region) formula to the Filters card
- D. Add the Choose Region parameter to the Pages card
正解：C
解説：
To use the Choose Region parameter to interact with a chart by toggling between different regions, you should add the [Region] = [Choose Region] formula to the Filters card. This formula will create a boolean filter that returns TRUE if the value in the Region field matches the value in the Choose Region parameter, and FALSE otherwise. You can add this formula to the Filters card by right-clicking on it and selecting Add Filter from the menu. Then you can select Condition from the dialog box and enter the formula in the text box. This will filter the chart to show only the data for the selected region.
The other options are not correct for this scenario. Adding Region to the Filters card will create a categorical filter that shows a list of values from the Region field, but it will not use the Choose Region parameter. Adding the Choose Region parameter to the Pages card will create a page control that allows you to cycle through different values of the parameter, but it will not filter the chart. Setting the Choose Region parameter to Single Value (list) will change how the parameter control appears on the worksheet, but it will not affect how it interacts with the chart.

check the steps below in explanation
Explanation:
To split the Customer Name field into two fields named First Name and Last Name, you need to do the following steps:
Open the link to Book1 found on the desktop. This will open the Tableau workbook that uses the Superstore data source.
Go to the Data Source tab at the bottom of the workbook to see the data source page. You will see a table that shows the fields and values from the Superstore data source.
Right-click on Customer Name in the table and select Split from the menu. This will split the field into two fields based on a separator, which is a space by default. You will see two new fields named Customer Name - Split 1 and Customer Name - Split 2 in the table.
Right-click on Customer Name - Split 1 and select Rename from the menu. Type First Name as the new name and press Enter. This will rename the field as First Name.
Right-click on Customer Name - Split 2 and select Rename from the menu. Type Last Name as the new name and press Enter. This will rename the field as Last Name.
質問 # 33
You have the following dataset.
You plan to create a dashboard that will be filtered to show only data that is relevant to a specific Tableau user based on the Tableau_User_Name field You need to create a boolean calculated field to place on the data source finer Which formula should you use for the filter?
- A. ISFULLNAMETableu_USER_NAME))=USERNAME()
- B. NAMEUSERNAME()
- C. NAME Tableau-USER-NAME)
- D. USERNAME()=(Tableau_USER_NAME)
正解：D
解説：
To create a boolean calculated field to place on the data source filter, you should use the formula USERNAME() = [Tableau_user]. This formula will return TRUE if the current Tableau user name matches the value in the Tableau_user field, and FALSE otherwise. You can use this formula as a data source filter by dragging it to the Filters shelf and selecting TRUE from the menu. This will filter the data to show only the rows that are relevant to the specific Tableau user.
The other options are not correct for this scenario. NAME([Tableau_user]) is not a valid function in Tableau. ISFULLNAME([Tableau_user]) = USERNAME() is not a valid expression in Tableau. 'S' + STR([Sales]/1000) is not a boolean expression, but a string expression that converts sales to thousands with a prefix of "S".

What should you add?
- A. A reference band
- B. A reference line
- C. A distribution band
- D. An average line
正解：A
解説：
A reference band is a shaded area that shows a range of values on an axis. You can use a reference band to highlight a target range, a confidence interval, or a standard deviation. In this case, you want to add a reference band that shows the range of values from 0 to 100 on the y-axis. This will create a shaded area behind the bars that indicates the percentage of sales.
To add a reference band, you need to do the following steps:
Click on the Analytics tab on the left side of the workbook to open the Analytics pane. You will see a list of analytical objects that you can drag and drop onto your worksheet.
Drag Reference Band from the Analytics pane to Y-Axis on the worksheet. This will add a reference band on the y-axis that shows the average and confidence interval for all values.
Click on the Edit button on the reference band to open the Edit Reference Band dialog box. You will see options to customize your reference band.
Change the Band From value to 0 and the Band To value to 100. This will change the reference band to show the range of values from 0 to 100 on the y-axis.
Click OK to apply the changes. You will see that the reference band now shows a shaded area behind the bars.
