You have an Azure subscription that contains an Azure Synapse Analytics serverless SQL pool named Pool1.
You plan to deploy a data lake that will record the history of transactions executed against Pool1.
You need to recommend which type of file to use to store the history. The solution must ensure that the history is written in the scope of the related transaction.
Which file type should you recommend?

• A. Avro
• B. JSON
• C. Delta
• D. Parquet

You have a deployment pipeline for a Power BI workspace. The workspace contains two datasets that use import storage mode.
A database administrator reports a drastic increase in the number of queries sent from the Power Bi service to an Azure SQL database since the creation of the deployment pipeline.
An investigation into the issue identifies the following:
One of the datasets is larger than 1 GB and has a fact table that contains more than 500 million rows.
When publishing dataset changes to development, test, or production pipelines, a refresh is triggered against the entire dataset.
You need to recommend a solution to reduce the size of the queries sent to the database when the dataset changes are published to development, test, or production.
What should you recommend?

• A. In the dataset, delete the fact table.
• B. From Capacity settings in the Power Bi Admin portal, reduce the Max Intermediate Row Set Count setting.
• C. Configure the dataset to use a composite model that has a DirectQuery connection to the fact table.
• D. Request the authors of the deployment pipeline datasets to reduce the number of datasets republished during development.

You are using DAX Studio to analyze a slow-running report query. You need to identify inefficient join operations in the query. What should you review?

• A. the query history
• B. the server timings
• C. the query plan
• D. the query statistics

You are using DAX Studio to query an XMLA endpoint.
How should you complete the DAX expression? To answer, drag the appropriate values to the targets. Each value may be used once, more than once. may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this section, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
You have the Power Bl data model shown in the exhibit. (Click the Exhibit tab.)

Users indicate that when they build reports from the data model, the reports take a long time to load.
You need to recommend a solution to reduce the load times of the reports.
Solution: You recommend normalizing the data model.
Does this meet the goal?

• A. No
• B. Yes
