How is unstructured data retrieved from data storage?

The correct answer is B. SQL functions can be used to create different types of URLs pointing to the unstructured data. Snowflake provides SQL functions to generate different types of URLs for accessing unstructured data files stored in stages: pre-signed URLs (for unauthenticated temporary access), scoped URLs (for authenticated, time-limited access within Snowflake), and file URLs (for…

Explanation

Snowflake provides SQL functions to generate different types of URLs for accessing unstructured data files stored in stages: pre-signed URLs (for unauthenticated temporary access), scoped URLs (for authenticated, time-limited access within Snowflake), and file URLs (for persistent authenticated access). These URL-generating functions allow applications to retrieve and serve the raw unstructured files (images, PDFs, audio, etc.) without loading them into a table. The query results cache (C) is not applicable to unstructured file retrieval. Snowflake does not provide web extension rendering (D) or a GET-style copy command (A) as the primary retrieval mechanism for unstructured data.
