• A. False
• B. Unknown
• C. Not applicable
• D. True

Answer: (D)

In Snowflake, some stages are system-managed and cannot be altered or dropped using standard DDL. The User Stage is a per-user internal stage created automatically for that user, and its properties aren’t changeable or droppable. Similarly, the Table Stage is an internal stage tied to a specific table (referenced as @%table_name) and is used to load data into or unload data from that table; it isn’t something you can alter or drop independently. These stages exist to support per-user and per-table data operations, and they’re managed alongside the user or table they belong to. Because of this management model, the statement that the stage type cannot be altered or dropped is true.
