You must provision an Azure storage account that can handle at least 500 requests per second and store large images, videos, and audio streams. Which type of storage account should you provision?

Premium block blobs are optimized for high transaction rates and low latency, making them ideal for workloads requiring fast access to large, unstructured data like images, videos, and audio streams, and easily meeting the 500 requests per second requirement. Standard general-purpose v2 accounts offer lower cost but have lower performance limits, potentially struggling with the required transaction rate. Premium page blobs are designed for random read/write operations on VHDs used by Azure Virtual Machines, not for general-purpose object storage. Premium file shares are optimized for SMB and NFS file access, not for high-throughput object storage.
