                                                                                  質問 # 179
                                                                                  You have the Power Bl data model shown in the following exhibit.
                                                                                  You create two row-level security (RlS) roles named Manager and CFO.
                                                                                  You plan to publish the dataset to the Power Bl service.
                                                                                  You need to create DAX expressions for the RLS filters. The solution must meet the following requirements:
                                                                                  * Each manager must see only the data in the Sales and Human Resources tables for their own country.
                                                                                  * The CFO must be prevented from seeing the data in the Human Resources table.
                                                                                  * The CFO must see the sales data of all countries.

To answer, drag the appropriate expressions to the correct targets. Each expression may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
                                                                                  NOTE: Each correct selection is worth one point.

                                                                                  The Country table contains the following data.

                                                                                  You plan to publish the dataset to the Power Bl service.

                                                                                  Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is the same in each question in this series.
                                                                                  You have a Microsoft SQL Server database that contains the following tables.

                                                                                  The following columns contain date information:
                                                                                  - Date[Month] in the mmyyyy format
                                                                                  - Date[Date_ID] in the ddmmyyyy format
                                                                                  - Date[Date_name] in the mm/dd/yyyy format
                                                                                  - Monthly_returns[Month_ID] in the mmyyyy format
                                                                                  The Order table contains more than one million rows.
                                                                                  The Store table has a relationship to the Monthly_returns table on the Store_ID column. This is the only relationship between the tables.
                                                                                  You plan to use Power BI Desktop to create an analytics solution for the data.
                                                                                  You need to create a relationship between the Order table and the Store table on the Store_ID column.
                                                                                  What should you do before you create the relationship?

                                                                                  正解：C

                                                                                  Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
                                                                                  After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
                                                                                  You create a parameter named DataSourceExcel that holds the file name and location of a Microsoft Excel data source.
                                                                                  You need to update the query to reference the parameter instead of multiple hard-coded copies of the location within each query definition.
                                                                                  Solution: In the Power Query M code, you replace references to the Excel file with DataSourceExcel.
                                                                                  Does this meet the goal?

                                                                                  正解：B

From connecting to different data sources defined in Query Parameters to load different combinations of columns.
