The question asks which URL type allows access to unstructured data without Snowflake authentication or authorization tokens. Pre-signed URLs (option A) are specifically designed for this purpose - they provide temporary, time-limited access to files stored in Snowflake stages without requiring users to authenticate. The community discussion strongly supports this with 100% consensus on answer A, multiple upvoted comments referencing Snowflake documentation, and clear explanations that pre-signed URLs are ideal for scenarios like business intelligence applications where external users need file access without Snowflake credentials. Options B (Scoped URL), C (Signed URL), and D (File URL) are not the correct Snowflake terminology for this functionality - signed URLs typically refer to different authentication mechanisms in other systems, while scoped and file URLs don't provide the described unauthenticated access capability in Snowflake.
