Microsoft Azure Solutions Architect Expert AZ-305 Practice Question
Your company stores transactional data in Azure SQL Database and semi-structured data as Parquet files in Azure Data Lake Storage Gen2. Data scientists want to run ad-hoc T-SQL queries that can join the Parquet files with snapshots of the relational data, create quick visualizations in Power BI, and avoid provisioning or managing any clusters. They are willing to copy a small subset of the Azure SQL Database tables into the lake on demand but do not want a nightly ETL schedule. Which Azure service best meets these requirements while keeping administration and cost to a minimum?
Create an Azure Synapse Analytics workspace and use the built-in serverless SQL pool to query the data lake and exported relational snapshots.
Build an Azure Stream Analytics job that outputs the combined data to Power BI for interactive reporting.
Deploy Azure Data Factory pipelines to copy all data into a dedicated SQL pool and schedule nightly batch processing.
Provision Azure Analysis Services and import both data sets into a tabular model for reporting.
An Azure Synapse Analytics workspace with the built-in serverless SQL pool lets users query Parquet files in ADLS Gen2 through OPENROWSET or external tables and join them with lightweight copies of Azure SQL Database tables that have been exported to the lake. Because the pool is serverless, Microsoft manages the compute and charges apply only to the data processed per query, eliminating cluster administration. The workspace can be linked to Power BI for easy visualization. In contrast, Azure Data Factory and Azure Stream Analytics are designed for scheduled pipelines and real-time processing respectively, and Azure Analysis Services requires loading data into a tabular model first. Therefore, Azure Synapse Analytics serverless SQL pool is the most suitable choice.
