You are designing a Windows Azure application that will provide online backup storage for very large media files.
The application must be capable of storing an average of 1 GB of data for each user.
The application must provide random read/write access.
You need to recommend a durable data storage solution.
What should you recommend?

A.
Use a Windows Azure Drive.

B.
Use Windows Azure page blob storage.

C.
Use Windows Azure block blob storage.

D.
Use local storage on a Windows Azure instance.

Explanation:
The Blob service stores text and binary data. The Blob service offers the following three resources: the storage account, containers, and blobs. Within your storage account, containers provide a way to organize sets of blobs.

You can store text and binary data in either of two types of blobs:

Block blobs, which are optimized for streaming.

Page blobs, which are optimized for random read/write operations and which provide the ability to write to a range of bytes in a blob.
