Which Azure storage solution provides native support for POSIX (DP-900)

Correct answer: B. Azure Data Lake Storage.
Azure Data Lake Storage (ADLS) is a highly scalable and secure data lake solution that provides native support for POSIX-compliant access control lists (ACLs).
POSIX-compliant ACLs allow you to set fine-grained permissions on files and directories, enabling you to control access to your data at a granular level. This is particularly useful for enterprise-grade data analytics and big data workloads, where you need to ensure proper data governance and access control.

The other Azure storage solutions do not provide native support for POSIX-compliant ACLs:
A. Azure Table storage: This is a NoSQL key-value store and does not support POSIX-compliant ACLs.
C. Azure Queue storage: This is a message queuing service and does not provide file-level access control.
D. Azure Files: This is a fully managed file share service, but it uses traditional Windows-based access control mechanisms, not POSIX-compliant ACLs.

Therefore, Azure Data Lake Storage is the only Azure storage solution mentioned that offers native support for POSIX-compliant access control lists.
