I have two tables that I want to use in a calculation. One table contains customer master data, and the other table, sales transactions. Which of these join types do I use to ensure all customers, regardless of whether they bought something or not, are reported? Left Outer Referential Text Inner.
How does a referential join behave when columns from both the tables that are joined are requested in a query? an inner join is made an outer join is made a star join is made the join is ignored.
When is a design time filter applied? Before a join is executed After a join is executed At the same time as the join is executed.

I am getting an error when I try to activate my Calculation View. What could be wrong? I did not include an attribute view in the star join I have unmapped columns in a union I have not defined at least one column as a measure I did not set the join cardinalities I am referencing tables from different schemas .
When would I use a derived view? When I need to use an attribute view more than once in an analytic view So changes I make to an attribute view are immediately reflected in models where the attribute view is consumed When I need to apply filters to attributes When I need to calculate extra columns.

What information about my Calculation View can I discover using Performance Analysis Mode? choose 2 Compression % for column tables used in model Time taken to process each step during execution Number of rows in referenced tables Partition type of referenced tables.
What is the purpose of schema mapping? To allow tables from one schema to be visible in another schema To automatically adjust models during import to use the final production schema and not the authoring schema To create a table in one schema that is derived from a table in another schema To ensure the correct access sequence is applied when a table appears in multiple schemas.
Why would I export content using Developer Mode? To export application source code To export models and include all their historic log files To export both the design time and run time objects To export individual objects .
When would I use mass copy? To copy information models while keeping the references between all the copied objects consistent To copy multiple models using wild cards in the selection criteria To improve the performance when copying many models by using parallelization The allow the copy to be run in the background.
In a level hierarchy, how are levels defined? By choosing a parent node followed by a sequence of child nodes to create a drill down order By defining an explicit sort sequence of specific values chosen from a single column By specifying the columns in a hierarchy table that should be available for drill down By selecting at least two columns that are available in the semantic node and placing them in the desired drill down sequence.
What is a parent child hierarchy? A continual hierarchy formed by linking multiple hierarchies A hierarchy formed by selecting two columns and assigning them to the role of parent or child A hierarchy that is formed by selecting specific the values of a column and assigning the values to the role of parent or child The assignment of hierarchy nodes to the roles of parent or child.
Which are valid methods for reducing the data set in a Calculation View? choose 4 Create a design time filter on a table column Include an aggregation node and define at least one measure for aggregation Mark columns as hidden in the semantic layer Implement domain fixed values Define a variable.

Which statements are true regarding variables? choose 3 A variable is used for filtering the data set by attributes A variable value cannot be empty A variable can be assigned to multiple attributes for filtering Variables can be used in calculated column expression A variable generates an WHERE clause in SQL.
When would I use a decision table? To define access priority when table locking occurs To provide hints to the SQL execution engine to ensure best performance To define the flow logic of a Calculation View To define reusable business rules .
What is the purpose of EXPLAIN PLAN tool? To suggest optimal design changes to your model To highlight data quality issues that can affect performance To highlight which execution engines are called To generate documentation from the calculation view settings .
Which of these are recommended to ensure good performance? choose 2 Join on key or indexed columns Projection nodes should always be placed above aggregation nodes in a graphical calculation view Filter data as early as possible in the data flow Avoid calculations after aggregations.
You have set the flag in your view to execute only in the SQL engine. What design rules must you follow in order to achieve the best performance? choose 2 Avoid use of input parameters, always use variables Do not include scripted calculation views in your model Do not include analytic views in your model You should also set the SQL flag in the underlying views.
Which are good practices when writing SQL? choose 2 Use variables to break up complex statements Avoid Grouping Sets Use IF-THEN-ELSE statements to help control the data flow Avoid mixing CE plan operators and SQL relational operators .
