   How do virtual warehouses provide workload isolation?

   • ABy limiting the number of queries each warehouse can run.
   • BBy using separate storage locations for each warehouse.
   • CBy running as independent compute clusters that do not compete for resources.
   • DBy sharing the same compute resources but prioritizing queries.

   A data analyst runs the same complex query on a large table multiple times throughout the day. They notice that the query runs much faster after the first execution. What is the primary reason for this performance improvement?

   • AThe data is cached in the virtual warehouse's local storage after the first query.
   • BThe storage layer has reorganized the data into a more efficient columnar format after the first query.
   • CThe virtual warehouse has scaled up to a larger size after the first query.
   • DThe results of the query are stored in the services layer, so subsequent runs skip the compute layer.

   What is the primary benefit of separating the storage, compute, and services layers in Snowflake's architecture?

   • AIt requires all queries to be processed in a single compute cluster.
   • BIt allows each layer to scale independently based on demand.
   • CIt forces all data to be stored in a single region.
   • DIt eliminates the need for metadata management.

   A company needs to share a large dataset with an external partner. The partner will query the data using their own Snowflake account. How does Snowflake's architecture enable this without copying the data?

   • AThe partner is given direct access to the company's storage layer.
   • BThe partner must run a query on the company's virtual warehouse to access the data.
   • CThe company creates a share that references the data in its storage layer, and the partner's services layer can access it.
   • DThe data is copied to the partner's storage layer during the sharing process.

   A user is running a query and wants to understand how Snowflake determines the most efficient way to execute it. Which component of the services layer is responsible for this?

   • AThe cloud provider's load balancer.
   • BThe virtual warehouse's query scheduler.
   • CThe query optimizer in the services layer.
   • DThe storage layer's metadata manager.
