Exam AZ-305 topic 4 question 61 discussion

B. a general purpose v2 storage account that has hierarchical namespace enabled. GPv2 with hierarchical structure gives you the following provisions: -The storage must support three levels of subfolders. -The storage must support access control lists (ACLs). -The storage must support 1 PB of data. -The data must be stored in blob storage.

B is the answer. https://learn.microsoft.com/en-us/azure/storage/blobs/data-lake-storage-namespace With a hierarchical namespace enabled, a storage account becomes capable of providing the scalability and cost-effectiveness of object storage, with file system semantics that are familiar to analytics engines and frameworks.

Given answer B is correct, However if Data Lake Gen 2 was in the answer i would chose it and here is why When you go to you GPV2 storage account and click on properties, you will see option => Hierarchical namespace = DISABLED and when you try to enable it => you will be greeted with this message "Upgrade to a storage account with Azure Data Lake Gen2 capabilities If you’re looking to use your storage account for data analytics and big data storage, you should consider upgrading to Azure Data Lake Storage Gen2, which will enable hierarchical namespace on the account" This indicates that GPV2 hierarchical namespace is being phased out and i will not be surprised that GPV2 in near feature will be facing the same faith as GPV1 Now second point => The storage must support 1 PB of data. well the Default maximum storage account capacity is 5PiB https://learn.microsoft.com/en-us/azure/storage/common/storage-account-overview

B. a general purpose v2 storage account that has hierarchical namespace enabled. Azure Blob Storage is designed to store large amounts of unstructured object data, such as text or binary data, and can store petabytes of data. General Purpose v2 accounts deliver the lowest per-gigabyte capacity prices for Azure Storage, as well as industry-competitive transaction prices. Hierarchical namespace allows the blob storage to support multiple levels of directories and subfolders. Moreover, when you enable a hierarchical namespace, the data in the account becomes accessible through Azure Data Lake Storage Gen2, which supports access control lists (ACLs) for granular permissions.

The answer is B: general purpose v2 storage account. The first reason is that we require Access Control lists, which require either block blob storage or general v2. Then we narrow it down even more because we require three levels of subfolders which mean we need hierarchical name spaces enabled which only option B has.
