Answer: User authentication, Infrastructure management

The Cloud Services layer in Snowflake is responsible for coordinating and managing the overall system, not for direct data processing or storage. Based on the community discussion and Snowflake documentation, the correct answers are D (User authentication) and E (Infrastructure management). These are core functions of the Cloud Services layer, which handles authentication, infrastructure coordination, metadata management, query parsing, and access control. Option A (Data storage) is handled by the Storage layer, Option B (Dynamic data masking) is a data protection feature applied at the query level, and Option C (Partition scanning) occurs in the Compute layer during query execution.
