Which Snowflake architectural layer is responsible for a query execution plan?
The Snowflake architectural layer responsible for a query execution plan is the Cloud Services layer. This layer is responsible for various services including query parsing, optimization, and creating execution plans. It connects all other components and manages activities such as authentication, infrastructure management, and metadata management.
Cloud Services The cloud services layer is a collection of services that coordinate activities across Snowflake. These services tie together all of the different components of Snowflake in order to process user requests, from login to query dispatch. The cloud services layer also runs on compute instances provisioned by Snowflake from the cloud provider. Services managed in this layer include: Authentication Infrastructure management Metadata management Query parsing and optimization Access control
Made a mistake buying this set, all answers are wrong. Will never ever recommend this to anyone. Refrain from using this.
At least the discussion section under each question looks very valuable from learning perspective. You have a chance to see other opinions, sometimes different than yours which urges you to your own deeper research and better understanding.
Query execution is performed in the processing layer. Snowflake processes queries using “virtual warehouses”
Correct but the question is about Explain/Query execution plan not Query execution. Perhaps C.
cloud services layer. C is the answer
why not A? Compute layer
Query execution plan, does not need an active virtual warehouse to complete as it only compiles the SQL queries and consumes only Cloud service credits, since its a metadata operation. I would go with C.
correct answer is C
Cloud services layer
cloud services, Query Processing and Data storage are the layers. Must be A compute as its not any of the other 3. It must imply query processing layer.
why not a Cloud Provider as per the below- Query execution is performed in the processing layer. Snowflake processes queries using “virtual warehouses”. Each virtual warehouse is an MPP compute cluster composed of multiple compute nodes allocated by Snowflake from a cloud provider.

C. Cloud services

The Snowflake architectural layer responsible for a query execution plan is: C. Cloud services The Cloud Services layer in Snowflake handles activities such as query optimization, compilation, and execution planning.
This is A not D, because it's the compute layer that execute, cloud services will be more for query parsing
