AZ-900 - Microsoft Azure Fundamentals Azure Storage Services Questions and Answers

Question 1

A company needs to store several terabytes of unstructured data, such as videos, images, and documents, in Azure. The data must be accessible from anywhere in the world via HTTP or HTTPS. Which Azure Storage service is the most suitable for this requirement?

Accepted Answer

Azure Blob Storage

Answer

Azure Blob Storage is the correct choice because it is an object storage solution optimized for storing massive amounts of unstructured data like text or binary data. It's ideal for scenarios such as serving images or documents directly to a browser, streaming video and audio, and storing data for backup and restore.

Question 2

An organization wants to migrate its on-premises file server to Azure to provide a cloud-based file share for its employees. The solution must support access via the standard Server Message Block (SMB) protocol so that users can map it as a network drive. Which Azure Storage service should they use?

Accepted Answer

Azure Files

Answer

Azure Files is the appropriate service as it offers fully managed file shares in the cloud that are accessible via the industry-standard Server Message Block (SMB) protocol. This allows for a seamless 'lift-and-shift' of applications and user shares that rely on traditional file server protocols.

Question 3

A developer is building a distributed application where components need to communicate asynchronously. The application requires a reliable messaging solution to create a backlog of work to be processed, helping to decouple the components. Which Azure Storage service is designed for this purpose?

Accepted Answer

Azure Queue Storage

Answer

Azure Queue Storage is designed for storing large numbers of messages that can be accessed from anywhere. It is commonly used to create a backlog of work to process asynchronously, which effectively decouples application components and improves scalability and fault tolerance.

Question 4

A company needs to store a large dataset of customer information as a NoSQL key/value store. The data is semi-structured, and queries will be performed using a partition key and a row key for fast access. Which Azure Storage service provides a cost-effective solution for this scenario?

Accepted Answer

Azure Table Storage

Answer

Azure Table Storage is a NoSQL service that stores large amounts of structured, non-relational data. It is a key-value store with a schemaless design, making it ideal for semi-structured data. Data is accessed via a partition key and row key, which allows for fast retrieval.

Question 5

An organization needs to store long-term backup and archival data for compliance purposes at the lowest possible cost. The data will be accessed very rarely, and a retrieval time of several hours is acceptable. Which Azure Blob Storage access tier is the most cost-effective choice?
