DP-900Domain 3: Describe Considerations for Working with Non-Relational Data on AzureNon-Relational Data on AzuremediumSingle choice
A big-data analytics team needs a data lake with true hierarchical directories (folders you can rename atomically) and POSIX-style permissions, built on Blob Storage. Which capability?
A.Standard Blob Storage containers
Flat namespace — no true directories or POSIX ACLs.
B.Azure Data Lake Storage Gen2 (hierarchical namespace enabled)
Hierarchical namespace + ACLs = ADLS Gen2. Correct.
C.Azure Files
Files is SMB shares — not analytics lake storage.
D.Azure Table Storage
Table is key-attribute store — not a filesystem.
Why this answer
ADLS Gen2 = Blob Storage + hierarchical namespace: real directories, atomic rename, ACLs — the foundation of Azure data lakes for analytics. Standard Blob containers are flat namespaces with virtual folders.
