You plan to migrate data to Azure. The IT department at your company identifies 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). You need to meet the requirements. What should you use?
Correct Answer: B
Microsoft recommends that you use a GPv2 storage account for most scenarios. It supports up to 5 PB, and blob storage including Data Lake storage. Note: A key mechanism that allows Azure Data Lake Storage Gen2 to provide file system performance at object storage scale and prices is the addition of a hierarchical namespace. This allows the collection of objects /files within an account to be organized into a hierarchy of directories and nested subdirectories in the same way that the file system on your computer is organized. 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.
