Which of the following conditions must be met in order to return results from the results cache? (Select TWO).

1. A. The user has the appropriate privileges on the objects associated with the query
2. B. Micro-partitions have been reclustered since the query was last run
3. C. The new query is run using the same virtual warehouse as the previous query
4. D. The query includes a User Defined Function (UDF)
5. E. The query has been run within 24 hours of the previously-run query

Correct Answer: AE
To return results from the results cache in Snowflake, certain conditions must be met:
✑ Privileges: The user must have the appropriate privileges on the objects associated with the query. This ensures that only authorized users can access cached data.
✑ Time Frame: The query must have been run within 24 hours of the previously-run query. Snowflake??s results cache is designed to store the results of queries for a short period, typically 24 hours, to improve performance for repeated queries.

For which use cases is running a virtual warehouse required? (Select TWO).

1. A. When creating a table
2. B. When loading data into a table
3. C. When unloading data from a table
4. D. When executing a show command
5. E. When executing a list command

Correct Answer: BC
Running a virtual warehouse is required when loading data into a table and when unloading data from a table because these operations require compute resources that are provided by the virtual warehouse23.

If 3 size Small virtual warehouse is made up of two servers, how many servers make up a
Large warehouse?

1. A. 4
2. B. 8
3. C. 16
4. D. 32

Correct Answer: B
In Snowflake, each size increase in virtual warehouses doubles the number of servers. Therefore, if a size Small virtual warehouse is made up of two servers, a Large warehouse, which is two sizes larger, would be made up of eight servers (2 servers for Small, 4 for Medium, and 8 for Large)2.
Size specifies the amount of compute resources available per cluster in a warehouse. Snowflake supports the following warehouse sizes:
