Microsoft Azure Fundamentals AZ-900 Practice Question

The Azure Blob Storage Cool tier is intended for data that is not accessed frequently but still requires reasonably fast access. It provides lower storage costs than the Hot tier without the higher access latency of the Archive tier. The Archive tier may seem cost-effective, but it is designed for data that is rarely accessed and has a retrieval delay of several hours, which is detrimental for a streaming user experience. The Premium performance tier is optimized for high transaction rates and provides lower latency but at a higher cost, making it unnecessary for the less frequently accessed videos.
