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

Which type of Azure storage is best suited for Video and Audio streaming?

1. A SQL Database

2. B Cosmos DB

3. C Data Lake

4. D BLOB storage

The correct answer is: D BLOB storage

BLOB storage is indeed the optimal choice for video and audio streaming in Azure. This type of storage is specially designed to handle large amounts of unstructured data, making it ideal for media files such as videos and audio streams. BLOB storage offers the scalability and performance needed for streaming, allowing for quick access and delivery of content, which is essential for a seamless user experience. Additionally, BLOB storage supports various access tiers (Hot, Cool, and Archive) that can help manage costs based on how frequently data is accessed. This flexibility is particularly beneficial in streaming scenarios, where content may have varying levels of demand. The other types of storage mentioned, such as SQL Database and Cosmos DB, are structured database solutions designed for transactional data and NoSQL workloads, rather than for large binary files like videos. Data Lake could be utilized for analytics on large datasets but is not specifically tailored for efficient media streaming like BLOB storage is. These characteristics make BLOB storage the most suitable choice for video and audio streaming.
