Microsoft Certified: Azure Fundamentals (AZ-900) Practice Exam

Which service is optimized for storing massive amounts of unstructured data?

1. Azure Files

2. Blob Storage

3. Archive Storage

4. Queue Storage

The correct answer is: Blob Storage

The service optimized for storing massive amounts of unstructured data is Blob Storage. This service is specifically designed to handle large volumes of unstructured data such as documents, images, videos, and backups. Blob Storage allows you to store any type of text or binary data, making it highly versatile for various use cases. Blob Storage is particularly suited for scenarios where scalability and performance are critical, as it can scale to meet the needs of your application without a predefined limit on the amount of data. This makes it a preferred option for applications that require the handling of large datasets, such as big data analytics, media streaming, and content management systems. Other services, while they have their specific use cases, do not match Blob Storage's capabilities in handling unstructured data at scale. For instance, Azure Files is more focused on providing file shares that can be accessed via the SMB protocol, making it ideal for traditional applications that need a file system interface. Archive Storage targets long-term data archival at a lower cost, but is not optimized for high-performance access. Queue Storage is designed for messaging between application components rather than data storage.
