Designing Azure Infrastructure Solutions — Question 110

You need to recommend an Azure Storage solution that meets the following requirements:
✑ The storage must support 1 PB of data.
✑ The data must be stored in blob storage.
✑ The storage must support three levels of subfolders.
✑ The storage must support access control lists (ACLs).
What should you include in the recommendation?

Answer options

• A. a premium storage account that is configured for block blobs
• B. a general purpose v2 storage account that has hierarchical namespace enabled
• C. a premium storage account that is configured for page blobs
• D. a premium storage account that is configured for file shares and supports large file shares

Correct answer: B

Explanation

The correct answer is B because a general purpose v2 storage account with hierarchical namespace enabled supports blob storage with the ability to create subfolders and manage access through ACLs. Option A is incorrect as it does not support hierarchical namespaces, option C is for page blobs which do not meet the requirements, and option D is focused on file shares, not blob storage.
