You need to deploy an Azure Storage account that will: store data for multiple users, encrypt each user's data with a separate key, and ensure all data in the account is encrypted using customer-managed keys. Which storage option should you deploy?

The correct option is "blobs in a general purpose v2 storage account" because Azure Blob Storage, specifically within a general-purpose v2 storage account, supports per-blob encryption with customer-managed keys (CMK). This allows each user's data (stored as individual blobs) to be encrypted with a unique key, meeting the requirement for separate user keys. General-purpose v2 accounts offer the necessary features for CMK. "Files in a premium file share storage account" and "files in a general purpose v2 storage account" are incorrect because Azure Files does not support per-file encryption with customer-managed keys; CMK applies at the storage account level for Azure Files, not per individual file. "Blobs in an Azure Data Lake Storage Gen2 account" is incorrect because while ADLS Gen2 is built on Blob Storage, its primary use case is analytics, and the per-blob CMK feature is a core Blob Storage capability available in general-purpose v2 accounts, which is the most direct answer for this specific requirement.
