Answer: Metadata management, Authentication

The correct answers are A (Metadata management) and C (Authentication). According to Snowflake's architecture documentation and the community discussion consensus (with 100% agreement and multiple upvoted comments), the cloud services layer is responsible for managing metadata (including database structures, columns, data types) and handling user authentication/authorization. Options B (Object authorization) is managed by the security layer, D (Query execution) is performed by the query processing layer, and E (Result caching) is handled by the query processing and storage layers, not the cloud services layer.
