There is a team of developers and data scientists and you are a security administrator on that team. It is planned to use Azure Databricks to perform data analysis. You are tasked to design an…

Data Lake Storage Gen1 is an older generation service that is being retired and lacks the full feature set and performance of Gen2, particularly around tighter integration with Blob storage features like SAS.

Azure Data Lake Storage Gen2 (ADLS Gen2) meets all specified requirements by providing a Hadoop-compatible file system with hierarchical namespace, robust file-level access control lists (ACLs) for granular permissions, and full support for Shared Access Signatures (SAS) to grant time-limited, specific permissions to storage resources. It is optimized for big data analytics workloads like those from Azure Databricks.

Azure SQL Data Warehouse (now Azure Synapse Analytics) is a relational data warehousing service, not a file system-based storage repository for raw data that would typically integrate with Databricks in this manner.

A general-purpose v1 storage account lacks the hierarchical namespace and optimized performance for big data analytics workloads, and its ACL capabilities are less granular than those offered by ADLS Gen2.
