                                  質問 # 94
                                  Hotspot Question
                                  You have a semantic model that has the relationships shown in the following exhibit.

                                  Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
                                  NOTE: Each correct selection is worth one point.

                                  正解：

                                  解説：

                                  Explanation:
                                  Box 1: role-playing
                                  We see that DimDate relates to FactOrderDetails in three ways: to the OrderDate, to the ShippedDate and to the RequiredDate.
                                  Note: Role-playing dimensions
                                  A role-playing dimension is a dimension that can filter related facts differently. For example, at Adventure Works the date dimension table has three relationships to the reseller sales facts. The same dimension table can be used to filter the facts by order date, ship date, or delivery date.
                                  Box 2: filter the FactOrderDetail on OrderDate
                                  The relationship between DimDate(Date) and FactOrderDetails(OrderDate) is the active relation.

                                  質問 # 95
                                  You are using Power Bi Desktop to connect to an Azure SQL database The connection is configured as shown in the following exhibit.


                                  Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic NOTE: Each correct solution is worth one point

                                  正解：

                                  解説：
                                  Explanation

                                  https://docs.microsoft.com/en-us/power-query/connectors/azuresqldatabase The following table lists all of the advanced options you can set in Power Query Desktop and Power Query Online.
                                  Advanced option
                                  Description
                                  Command timeout in minutes
                                  If your connection lasts longer than 10 minutes (the default timeout), you can enter another value in minutes to keep the connection open longer. This option is only available in Power Query Desktop.
                                  SQL statement
                                  For information, go to Import data from a database using native database query.
                                  Include relationship columns
                                  If checked, includes columns that might have relationships to other tables. If this box is cleared, you won't see those columns.
                                  Navigate using full hierarchy
                                  If checked, the navigator displays the complete hierarchy of tables in the database you're connecting to. If cleared, the navigator displays only the tables whose columns and rows contain data.
                                  Enable SQL Server Failover support
                                  If checked, when a node in the Azure SQL failover group isn't available, Power Query moves from that node to another when failover occurs. If cleared, no failover occurs.


                                  質問 # 96
                                  You are modifying a Power Bi model by using Power Bl Desktop.
                                  You have a table named Sales that contains the following fields.

                                  You have a table named Transaction Size that contains the following data.

                                  You need to create a calculated column to classify each transaction as small, medium, or large based on the value in Sales Amount.
                                  How should you complete the code? To answer, drag the appropriate values to the correct targets. Each value 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.

                                  正解：

                                  解説：

                                  Explanation

                                  質問 # 97
                                  You are creating a report in Power BI Desktop.
                                  You load a data extract that includes a free text field named coll.
                                  You need to analyze the frequency distribution of the string lengths in col1. The solution must not affect the size of the model.
                                  What should you do?

                                  正解：A

                                  解説：
                                  From Power Query.. highlight the column.. from the tab view select Column Profile Option.. in the Value distribution section that appears below, from the 3dots.. you can change to group by text length distribution


                                  質問 # 98
                                  You have a Power BI semantic model that contains two tables named Dim Location and Fact Deliveries. The relationships between the tables are configured as shown in the following table.

                                  The model contains one measure that has the following formula.
                                  Deliveries = COUNTROWS( ' fact Deliveries ' )

                                  正解：

                                  解説：

                                  Explanation:

                                  The completed mapping shown in the answer area is correct. The case is framed around this condition: you have a power bi semantic model that contains two tables named dim location and fact deliveries. the relationships between the tables are configured as shown in the following table. Cardinality describes uniqueness on each side of a relationship; cross-filter direction controls how filters travel. Both settings must match the model grain or totals and security filtering can become unreliable. This directly matches the current study-guide objective " Define a relationship ' s cardinality and cross-filter direction " . The opposite cardinality or unnecessary bidirectional filtering can duplicate results, block propagation, or create ambiguity rather than solve the stated model path.
