You plan to store delimited text files in an Azure Data Lake Storage account that will be organized into department folders.

You need to configure data access so that users see only the files in their respective department folder.

Solution: From the storage account, you disable a hierarchical namespace, and you use RBAC (role-based access control).

Does this meet the goal?

Show Answer
Correct Answer: B

Using Role-Based Access Control (RBAC) alone is not sufficient for configuring data access in a way that allows users to see only the files in their respective department folder. Azure Data Lake Storage (ADLS) supports Access Control Lists (ACLs) which provide fine-grained control of permissions down to the individual file and folder levels. Disabling a hierarchical namespace would also not meet the goal, as a hierarchical namespace is essential for organizing data into folders. Therefore, disabling it would counteract the requirement to organize files into department folders.

Answer: No Azure RBAC : Storage accounts, containers. Cross resource Azure role assignments at subscription or resource group level.

In ADLS, once the hierarchal name space is enabled. It can't be disabled.

The answer is NO but the explanation should be updated. ADLS support ACLs and hierarchy cannot be disabled on Azure Blob Storage once it was enabled
