You plan to use an Azure Storage account to house data assets. The solution must support immutable storage, disable anonymous access to the account, and support ACL-based Azure AD permissions. Which storage offering should you choose?

Azure Data Lake Storage Gen2 (ADLS Gen2) is the correct choice because it natively supports all the requirements. It offers immutable storage through features like WORM (Write Once, Read Many) policies, which are crucial for data governance and compliance. ADLS Gen2 also integrates seamlessly with Azure Active Directory (Azure AD) for authentication and authorization, allowing for fine-grained, ACL-based permissions on files and folders, and inherently disables anonymous access. Azure Files provides shared file storage but lacks the advanced immutable storage features and hierarchical namespace optimized for analytics that ADLS Gen2 offers. Azure NetApp Files is a high-performance file storage service, primarily for enterprise workloads, but it doesn't provide the immutable storage or the specific ADLS Gen2-style ACLs required. Azure Blob Storage is the foundation for ADLS Gen2, but ADLS Gen2 adds the hierarchical namespace and enhanced ACLs necessary for data lake scenarios, making it the more complete solution for these requirements.
