Exam SnowPro Core topic 1 question 1338 discussion

Snowflake object owners lose their ability to grant privileges on their own objects when those objects reside in a managed access schema. In standard (non‑managed) schemas, object owners (roles holding the OWNERSHIP privilege on the object) can grant or revoke privileges. However, in a managed access schema—created via CREATE SCHEMA … WITH MANAGED ACCESS—only the schema owner (the role with OWNERSHIP on the schema) or any role with the global MANAGE GRANTS privilege can grant privileges on objects within that schema; individual object owners are no longer authorized to make grant decisions.
