To enable scale-out for a semantic model, you should first set Large dataset storage format to On (C) at the semantic model level. This configuration is necessary to handle larger datasets effectively in a scaled-out environment. References = Guidance on configuring large dataset storage formats for scale-out is available in the Power BI documentation.

Requirements:
Revert to previous versions of Model1.
Identify differences between saved versions.
Publish from Power BI Desktop.
Edit item definition files with Visual Studio Code.
Analysis:
To meet version control and difference tracking requirements, you must use Git integration in the Fabric workspace.
To enable editing with VS Code, you must use PBIP format (Power BI Project), which saves report/model as a folder with definition JSON files (not PBIX).
PBIX is a single binary file, not suitable for Git versioning or editing definition files.
"Enable users to edit in service" is irrelevant.
Correct Answers:
A). Enable Git integration for Workspace1.
C). Save Model1 in Power BI Desktop as a PBIP file.

Explanation:
The results will form a hierarchy of folders for each partition key. - Yes The resulting file partitions can be read in parallel across multiple nodes. - Yes The resulting file partitions will use file compression. - No Partitioning data by columns such as year, month, and day, as shown in the DataFrame write operation, organizes the output into a directory hierarchy that reflects the partitioning structure. This organization can improve the performance of read operations, as queries that filter by the partitioned columns can scan only the relevant directories. Moreover, partitioning facilitates parallelism because each partition can be processed independently across different nodes in a distributed system like Spark. However, the code snippet provided does not explicitly specify that file compression should be used, so we cannot assume that the output will be compressed without additional context.

When you need to return all rows that are present in both tables, you use a full outer join. This type of join combines the results of both left and right outer joins and returns all rows from both tables, with matching rows from both sides where available. If there is no match, the result is NULL on the side of the join where there is no match.
