Tableau Desktop Specialist 認定 TDS-C01 試験問題 (Q47-Q52):

質問 # 47
True or False: All rows from both tables are returned in an INNER JOIN

正解：B

解説：
The INNER JOIN keyword selects all rows from both tables as long as there is a match between the columns.
Consider 2 tables "Orders" and "Customers".
If there are records in the "Orders" table that do not have matches in "Customers", these orders will not be shown!


質問 # 48
Which of the following describes the best way to change the formatting at a workbook level?

正解：D

解説：
It is very much possible to specify the formatting at a WORKBOOK level (all sheets) instead of a single worksheet level.
You can quickly change how fonts, titles, and lines look in every view in a workbook by specifying format settings at the workbook level, instead of the worksheet level.
For example, you might want to use a specific font, size, and color so that all views adhere to your company's brand. You might also want to remove grid lines from your views-or make them more noticeable by increasing their pixel size or color.
You can also change the theme used by your workbook. Themes control items like the default font, colors, and line thickness. When you create a new workbook, it automatically uses the Default theme, which uses visual best practices.
Change fonts in your workbook:
You can change all fonts in your workbook or you can change fonts for only certain areas, such as just worksheet titles.
1) On the Format menu, select Workbook.
2) The Format Workbook pane replaces the Data pane on the left and provides a series of drop-down lists where you can change all font settings in a workbook, as well as the font settings for titles of worksheets, stories, and dashboards.

Note: If you have made font changes at the worksheet level, such as on a filter card or a worksheet title, changing the font at the WORKBOOK level will overwrite those changes.

Reset a workbook to its default settings
When you make changes to your workbook's font settings, a gray dot appears next to the setting in the Format Workbook pane. You can quickly switch back to default settings using the Reset to Defaults button.
1) On the Format menu, select Workbook.
2) In the Format Workbook pane, click Reset to Defaults.

質問 # 50
Question 30: Skipped
Using the CoffeeChain table, create a scatter plot of Profit (x-axis) vs Sales (y-axis) broken down by State. Add a Linear trend line to the view. What is its R-squared value?

正解：B

解説：
Trend lines have become popular questions in recent Tableau examinations. Follow along:
1) First drag Sales to the Rows shelf and Profit to the Columns shelf:

You will only see a single mark since the view is aggregated.
2) Now, break down this view by state. Drag State into Detail on the Marks shelf ( or directly to the view):

3) Finally, move to the Analytics pane, and drag Trend line to the view. When you drag it, select the Linear option!:


4) The following is our view. Hover over the trend line to see the R-squared value:


質問 # 51
Data blending simulates a traditional _________________ Join

正解：C

解説：
Explanation
Data blending simulates a traditional left join. The main difference between the two is when the aggregation is performed. A join combines the data and then aggregates. A blend aggregates and then combines the data.
