Exam DP-600 topic 1 question 30 discussion

Methods to Identify Frequently Used Columns: B. Use the Vertipaq Analyzer tool. Vertipaq Analyzer: This tool helps analyze the internal structure of your Power BI model. It provides detailed information about the storage and memory usage of your model, including which columns are frequently accessed and loaded into memory. This can help you identify unnecessary columns that are consuming resources. Steps: Export your Power BI model to a .pbix file. Open the .pbix file in Power BI Desktop. Use the Vertipaq Analyzer tool to analyze the model and review the column usage statistics. C. Query the $System.DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS dynamic management view (DMV). DMVs: Dynamic Management Views (DMVs) provide detailed information about the operations of your Power BI models. Specifically, the $System.DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS DMV can give you insights into the storage and usage patterns of individual columns within your model.

I think BC. A is only tobread data and D only memory allocations

Use the Vertipaq Analyzer tool. C. Query the $System.DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS dynamic management view (DMV).

B & C is the answer

Answer is A&B

Other Options: WRONG A. Use the Analyze in Excel feature: This feature allows for interaction with the model data in Excel but does not provide detailed insights into column-level memory usage. D. Query the DISCOVER_MEMORYGRANT DMV: This DMV provides information about memory grants for queries but does not provide detailed information about the columns loaded into memory.

IMHO, B & C Because: 1. The DISCOVER_STORAGE_TABLE_COLUMN_SEGMENTS schema rowset returns information about the column segments used for storing data for in-memory tables.<336> 2. Very often there could be a few columns that are not required in your Power BI model, but they take up a lot of space. This is easy to find with Vertipaq Analyzer.

B and C A. It’s more about data exploration and visualization. D. Provides information about memory grants for queries

B and C is the right answer.
