Answer: B
NEW QUESTION # 81
You have a Fabric warehouse that contains a table named SalesOrderDetail. SalesOrderDetail contains three columns named OrderQty, ProductID and SalesOrderlD. SalesOrderDetail contains one row per combination of SalesOrderlD and ProductID.
You need to calculate the proportion of the total quantity of each sales order represented by each product within the sales order.
Which T-SQL statement should you run?
Answer: B
Explanation:
Comprehensive Detailed Explanation
We need to calculate the proportion of the total quantity of each sales order represented by each product within the sales order.
Step 1: Analyze the requirement
Table: SalesOrderDetail
Columns: OrderQty, ProductID, SalesOrderID
Each row = one product in a sales order.
Requirement: For each SalesOrderID, calculate what percentage each product contributes to the total order quantity.
This means we must:
Calculate the total order quantity per SalesOrderID.
Divide each product's OrderQty by that total.
Express it as a percentage.
Step 2: Evaluate the options
A). Uses OVER(ORDER BY ProductID)
Wrong: ORDER BY does not segment data, it only defines sequence. We need grouping by sales order.
B). Uses OVER(PARTITION BY ProductID)
Wrong: This would calculate percentages per product across all sales orders, not per sales order.
C). Uses OVER(PARTITION BY SalesOrderID)
Correct: This computes the total OrderQty per SalesOrderID and divides each product's quantity by that total.
Exactly what the requirement asks.
D). Uses OVER(ORDER BY SalesOrderID)
Wrong: Again, ORDER BY just sequences rows, does not group them.
Step 3: Correct Query
SELECT
SalesOrderID,
ProductID,
OrderQty,
CAST(1. * OrderQty / SUM(OrderQty)
OVER(PARTITION BY SalesOrderID) * 100 AS DECIMAL(5,2))
AS PercentByProductID
FROM Sales.SalesOrderDetail;
Why Option C is Correct
PARTITION BY SalesOrderID ensures the denominator is the total quantity for the current order.
This produces the correct percentage breakdown of each product inside its sales order.

NEW QUESTION # 82
You have an Azure SQL database named DB1 and a Fabric workspace named Workspace1.
Workspace1 contains a lakehouse named LH1 and a Dataflow Gen2 named Dataflow1.
Dataflow1 includes a query named Query1 that loads data from DB1, applies transformations to the data, and then filters the data.
You discover that Query1 loads all the data before applying the transformations.
You need to ensure that Query1 uses query folding.
What should you do?
Answer: A
Explanation:
To ensure your Dataflow Gen2 query uses query folding when loading from Azure SQL to a Lakehouse, you need to verify that your transformations are being translated into a single SQL statement that is executed by the source database. This prevents the "load all data" behavior you are currently experiencing.
Rearrange Transformations
Power Query stops folding once it hits a step it cannot translate into SQL. To maximize efficiency:
Filter and Select early: Always place Filter Rows and Choose Columns steps as early as possible. This ensures only necessary data is retrieved from Azure SQL.

NEW QUESTION # 83
You have a Fabric tenant.
You plan to create a Fabric notebook that will use Spark DataFrames to generate Microsoft Power Bl visuals.
You run the following code.
For each of the following statements, select Yes if the statement is true. Otherwise, select No. NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
* The code embeds an existing Power BI report. - No
* The code creates a Power BI report. - Yes
* The code displays a summary of the DataFrame. - Yes
The code provided seems to be a snippet from a SQL query or script which is neither creating nor embedding a Power BI report directly. It appears to be setting up a DataFrame for use within a larger context, potentially for visualization in Power BI, but the code itself does not perform the creation or embedding of a report.
Instead, it's likely part of a data processing step that summarizes data.

NEW QUESTION # 84
You have a Fabric tenant that contains the workspaces shown in the following table.
You have a deployment pipeline named Pipeline1 that deploys items from Workspace_DEV to Workspace_TEST. In Pipeline1, all items that have matching names are paired.
You deploy the contents of Workspace_DEV to Workspace_TEST by using Pipeline1.
What will the contents of Workspace_TEST be once the deployment is complete?
Answer: A
Explanation:
Workspace_DEV contents:
Lakehouse1, Notebook1, Pipeline1, SemanticModel1
Workspace_TEST contents (before deployment):
Lakehouse2, Notebook2, SemanticModel1
After deployment:
SemanticModel1 # same name, so it will be paired and overwritten with the DEV version.
Lakehouse1 and Notebook1 # new items, so they will be added to TEST.
Lakehouse2 and Notebook2 # remain because they don't conflict in name.
Pipeline1 # new item, so it will also be added.
So the final content is:
Lakehouse1, Lakehouse2, Notebook1, Notebook2, Pipeline1, SemanticModel1 Reference:
Deployment pipelines pairing behavior
