Which statement describes a limitation related to attaching a row access policy to streams?

• A. Snowflake does not support attaching a row access policy to the stream object itself
• B. Snowflake supports attaching to streams but not tables
• C. Row access policies can be attached to streams but not to tables
• D. Streams are not protected by row access policies

Answer: (A)

Row access policies filter data by applying predicates at read time, and they are attached to tables (or views) in Snowflake. Streams, however, are change-tracking objects tied to a base table and do not store data themselves. Because streams aren’t data containers, Snowflake doesn’t support attaching a row access policy to the stream object itself. To enforce row-level access, you attach the policy to the underlying base table (or use a secure view that references the stream). This is why the statement describing this limitation is the best fit.
