質問 # 18
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.

質問 # 21
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. Add both sheets to the dashboard. Set Fit to Fix width.
- B. Drag a blank object to the dashboard and add both sheets to the dashboard. Set Fit to Entire view.
- C. Drag a horizontal container to the dashboard and add both sheets to the container. Set the Fit to Standard.
- D. Drag a vertical container to the dashboard and add both sheets to the container. Set Fit to Entire view.
正解：D
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:

質問 # 23
You have two tables named Employeelnfo and DepartmentInfo. Employeelnfo contains four fields named Full Name, Department ID, Start Date, and Salary.
DepartmentInfo contains four fields named Department Name, Size, Department ID, and VP.
You want to combine the tables to meet the following requirements:
. Each record in Employeelnfo must be retained in the combined table.
. The records must contain the Department Name, Size, and VP fields.
* Every record must have a full name.
Which type of join should you use?
- A. Full outer
- B. Inner
- C. Union
- D. Left
正解：D
解説：
To combine the tables and meet the requirements, you should use a left join. A left join will keep all the records from the left table (Employeelnfo) and match them with the records from the right table (DepartmentInfo) based on the common field (Department ID). If there is no matching record in the right table, the fields from the right table will be null. This way, you will retain all the records from Employeelnfo, and also include the Department Name, Size, and VP fields from DepartmentInfo. Every record will have a full name because it is a field from the left table. A left join will look like this:
