DP-203 Certification Practice Question #21

Question

You build a data warehouse in an Azure Synapse Analytics dedicated SQL pool.
Analysts write a complex SELECT query that contains multiple JOIN and CASE statements to transform data for use in inventory reports. The inventory reports will use the data and additional WHERE parameters depending on the report. The reports will be produced once daily.
You need to implement a solution to make the dataset available for the reports. The solution must minimize query times.
What should you implement?

Accepted Answer

Microsoft Learn guidance on dedicated SQL pool partitioning emphasizes choosing a column that supports lifecycle management and common query filters, which usually means a date key for large fact-style tables. That makes the date-partitioning choice the most defensible answer, even though real implementations must also ensure partitions are not too small.
