Anonymous public read access
Supported only by Blob Storage.
It supports:
- Public read access for blobs only: access granted only to blobs within the container and users are prevented from enumerating the blobs in the container
- Public read access for blobs and container: access granted on blobs and container data (everything)
Optimize storage performance in Azure Data Lake Storage Gen 1
It’s recommended to batch smaller files into larger files.
A file of at least 255 MB and less than 2 GB is recommended.
Azure Data Lake Analytics
It’s a batch processing service that integrates with Azure Data Lake. It allows developers to write code by using U-SQL, which is a language that combines declarative SQL with imperative C#. Data is stored as relational data and pricing is by batch job.
Administer storage account, which type of authentication?
Primary or secondary key. (In the questions both are correct)
An account Shared Access Signature doesn’t allow to administer the storage account.
Shared Access Signatures
A shared access signature (SAS) provides secure delegated access to resources in your storage account. With a SAS, you have granular control over how a client can access your data. You can control what resources the client may access, what permissions they have on those resources, and how long the SAS is valid, among other parameters.
User delegation SAS
Secured by Azure Active Directory credentials and permissions specified for the SAS. A user delegation applies to Blob Storage only.
Service SAS
A service SAS is secured with the storage account key. A service SAS delegates access to a resource in only one of the Azure Storage services: Blob storage, Queue storage, Table storage, or Azure Files.
Account SAS
An account SAS is secured with the storage account key. An account SAS delegates access to resources in one or more of the storage services. All of the operations available via a service or user delegation SAS are also available via an account SAS. Additionally, with the account SAS, you can delegate access to operations that apply at the level of the service, such as Get/Set Service Properties and Get Service Stats operations. You can also delegate access to read, write, and delete operations on blob containers, tables, queues, and file shares that are not permitted with a service SAS.
