You have a Fabric workspace that contains a lakehouse and a notebook named Notebook1. Notebook1 reads data into a DataFrame from a table named Table1 and applies transformation logic. The data from the DataFrame is then written to a new Delta table named Table2 by using a merge operation.You need to consolidate the underlying Parquet files in Table1.Which command should you run?
Answer(s): C
To consolidate the underlying Parquet files in Table1 and improve query performance by optimizing the data layout, you should use the OPTIMIZE command in Delta Lake. The OPTIMIZE command coalesces smaller files into larger ones and reorganizes the data for more efficient reads. This is particularly useful when working with large datasets in Delta tables, as it helps reduce the number of files and improves performance for subsequent queries or operations like MERGE.
You have five Fabric workspaces.You are monitoring the execution of items by using Monitoring hub.You need to identify in which workspace a specific item runs.Which column should you view in Monitoring hub?
Answer(s): G
To identify in which workspace a specific item runs in Monitoring hub, you should view the Location column. This column indicates the workspace where the item is executed. Since you have multiple workspaces and need to track the execution of items across them, the Location column will show you the exact workspace associated with each item or job execution.
You have a Fabric workspace that contains a warehouse named DW1. DW1 is loaded by using a notebook named Notebook1.You need to identify which version of Delta was used when Notebook1 was executed.What should you use?
Answer(s): D
DRAG DROP (Drag and Drop is not supported) (Drag and Drop is not supported)You have a Fabric workspace that contains a warehouse named Warehouse1.In Warehouse1, you create a table named DimCustomer by running the following statement.You need to set the Customerkey column as a primary key of the DimCustomer table.Which three code segments should you run in sequence? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.Select and Place:
Answer(s): A
To set the CustomerKey column as the primary key of the DimCustomer table, the steps need to follow the logical sequence of ensuring that the table structure can accommodate the primary key constraint.1. ALTER TABLE dbo.DimCustomer This command prepares the table for modification. It ensures the DimCustomer table is being updated to include the primary key.2. ADD CONSTRAINT PK_DimCustomer PRIMARY KEY CLUSTERED (CustomerKey) This command creates a clustered primary key constraint on the CustomerKey column. A primary key uniquely identifies each record and enforces uniqueness.3. ENFORCED This ensures that the primary key constraint is enforced, meaning it will actively validate and enforce uniqueness and nullability on the CustomerKey column.
You have a Fabric workspace that contains a semantic model named Model1.You need to dynamically execute and monitor the refresh progress of Model1.What should you use?
Semantic models in Microsoft Fabric are part of Power BI datasets and require refreshes to stay updated with the latest data.Dynamically executing and monitoring the refresh progress requires a tool or approach that integrates with Fabric's capabilities for semantic models.
