The correct answers are A and D based on Snowflake documentation and the community consensus. Option A is correct because when dropping an external stage, only the stage metadata is removed from Snowflake; the actual files in the external cloud storage (S3, GCS, or Azure) remain untouched. Option D is correct because when dropping an internal stage, all files stored within Snowflake are permanently deleted and cannot be recovered, as internal stages store data directly in Snowflake's managed storage. Option B is incorrect because external stage files are not removed. Option C is incorrect because internal stage files are not recoverable after drop. Option E is incorrect because all files in an internal stage are deleted, not just selected ones.
