Which Azure storage capability should an architect recommend to provide a hierarchical-namespace, POSIX-style filesystem on top of blob storage for big-data analytics?
AAzure Cache for Redis
BAzure Data Lake Storage Gen2 (hierarchical namespace on Blob Storage)
CAzure SQL Database
DAzure DNS
Answer & Solution
Correct answer: B. Azure Data Lake Storage Gen2 (hierarchical namespace on Blob Storage)
ADLS Gen2 adds HNS + POSIX semantics on Blob (per AZ-305 §2 unstructured + analytics). The others aren't data-lake storage.
