Answer: Cloud services layer

Query parsing and compilation occurs in the Cloud Services layer of Snowflake's three-layer architecture. The Cloud Services layer coordinates all system-wide activities including authentication, infrastructure management, metadata management, query parsing, optimization, and access control. This is explicitly documented in Snowflake's official documentation on key concepts, which was referenced in the community discussion. The other layers serve different purposes: the Compute layer (Virtual Warehouses) executes queries, the Storage layer stores data, and there is no 'Cloud agnostic layer' in Snowflake's standard architecture. The community discussion shows 100% consensus on option A with multiple users confirming this answer and referencing official documentation.
