• Chose B2

  a general purpose v2 storage account support 5 PB

• Chose B1

  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

  Seams about right For a 1 PB-scale Azure Storage solution that supports blob storage, hierarchical subfolders, and access control lists (ACLs), the best recommendation is: Recommended: Azure Data Lake Storage Gen2 Why Data Lake Storage Gen2? Supports Large-Scale Storage – Handles petabyte-scale data seamlessly. Optimized for Blob Storage – Provides high-throughput blob storage with hierarchical namespace support. Native Subfolder Structure – Supports three or more levels of directory hierarchy (like traditional file systems). Access Control Lists (ACLs) – Enables fine-grained permissions at the folder and file level, similar to NTFS.
