Question 4
Azure provides many ways to store your data. An Azure storage account contains all of your Azure Storage data objects, including blobs, file shares, queues, tables, and disks. The storage account provides a unique namespace for your Azure Storage data that's accessible from anywhere in the world over HTTP or HTTPS. Data in your storage account is durable and highly available, secure, and massively scalable.
Azure Storage offers several types of storage accounts. Each type supports different features and has its own pricing model. Which of the following are valid types of storage accounts? (Select four)
-
A
Append blobs Storage

Explanation
Storage Account: General Purpose V1 and Standard Blob are now legacy. Now we have General Purpose V2, Premium Block, Premium File Share and Premium Page Blob.
An Azure storage account contains all of your Azure Storage data objects, including blobs, file shares, queues, tables, and disks.

Types of storage accounts
Azure Storage offers several types of storage accounts. Each type supports different features and has its own pricing model.
The following table describes the types of storage accounts recommended by Microsoft for most scenarios. All of these use the Azure Resource Manager deployment model.
1 Data Lake Storage is a set of capabilities dedicated to big data analytics, built on Azure Blob storage. For more information, see Introduction to Data Lake Storage Gen2 and Create a storage account to use with Data Lake Storage Gen2.
2 ZRS, GZRS, and RA-GZRS are available only for standard general-purpose v2, premium block blobs, and premium file shares accounts in certain regions. For more information, see Azure Storage redundancy.
3 Premium performance storage accounts use solid-state drives (SSDs) for low latency and high throughput.
Legacy storage accounts are also supported. For more information, see Legacy storage account types.
You can’t change a storage account to a different type after it's' created. To move your data to a storage account of a different type, you must create a new account and copy the data to the new account.
A. Append blobs Storage is not a valid type of storage account. Append blobs are a specific type of block blob optimized for append operations, not a type of storage account.
B. Data Lake Storage is not a valid type of storage account. It is a separate service in Azure that is optimized for big data analytics workloads and offers features such as scalability and integration with analytics services.
C. Block blobs Storage is not a valid type of storage account. Block blobs are a type of storage object within a storage account, not a type of storage account itself.
D. Page blobs Storage is not a valid type of storage account. Page blobs are another type of storage object within a storage account, not a type of storage account.
E. Premium File Share storage accounts provide high-performance file shares that are optimized for enterprise workloads. They offer premium features such as higher throughput and lower latency.
F. Classic Storage is not a valid type of storage account. Classic storage accounts are the older version of Azure storage accounts and are not recommended for new deployments.
G. Premium Page Blob storage accounts are designed for scenarios that require high-performance, low-latency storage for virtual machine disks. They are optimized for random I/O operations.
H. General Purpose v1 storage accounts are an older version of the General Purpose storage accounts and are not recommended for new deployments. General Purpose v2 accounts offer more features and better performance.
I. Premium Block storage accounts offer high-performance, low-latency storage for I/O-intensive workloads. They are suitable for scenarios that require high transaction rates or low latency.
J. Container Storage is not a valid type of storage account. Containers are used for organizing and managing resources in Azure, but they are not a type of storage account.
K. General Purpose v2 storage accounts are the most common type of storage accounts and offer a balance of performance and cost-effectiveness. They support all Azure Storage services and are recommended for most scenarios.
L. Data Pool Storage is not a valid type of storage account. It is not a recognized storage account type in Azure.
