You will deploy an app App1 that must access an Azure Data Lake Storage account sa1 and perform Read, List, Create Directory, and Delete Directory operations via a private endpoint. What is the minimum number of private endpoints required for sa1?

Azure Data Lake Storage Gen2 accounts expose two distinct private endpoint sub-resources: blob for blob storage operations and dfs for Data Lake Storage Gen2 specific operations (like hierarchical namespace access). Since App1 needs to perform both standard blob operations (Read, List) and Data Lake-specific operations (Create Directory, Delete Directory), it requires a private endpoint for each sub-resource. Therefore, a minimum of two private endpoints are necessary: one for blob and one for dfs. If only blob was needed, one would suffice. If only dfs was needed, one would suffice.
