Topic 1: Exam pool A
Will data cached in a warehouse be lost when the warehouse is resized?
A.
Possibly, if the warehouse is resized to a smaller size and the cache no longer fits.
B.
Yes. because the compute resource is replaced in its entirety with a new compute resource.

No. because the size of the cache is independent from the warehouse size
D.
Yes. became the new compute resource will no longer have access to the cache encryption key

A sales table FCT_SALES has 100 million records.
The following Query was executed
SELECT COUNT (1) FROM FCT__SALES;
How did Snowflake fulfill this query?
A.
Query against the result set cache
B.
Query against a virtual warehouse cache
C.
Query against the most-recently created micro-partition
D.
Query against the metadata excite
Query against the metadata excite
Which of the following conditions must be met in order to return results from the results cache? (Select TWO).
A.
The user has the appropriate privileges on the objects associated with the query
B.
Micro-partitions have been reclustered since the query was last run
C.
The new query is run using the same virtual warehouse as the previous query
D.
The query includes a User Defined Function (UDF)
E.
The query has been run within 24 hours of the previously-run query
The user has the appropriate privileges on the objects associated with the query
The query has been run within 24 hours of the previously-run query
How would you determine the size of the virtual warehouse used for a task?
A.
Root task may be executed concurrently (i.e. multiple instances), it is recommended to leave some margins in the execution window to avoid missing instances of execution.
B.
Querying (select) the size of the stream content would help determine the warehouse size. For example, if querying large stream content, use a larger warehouse size.
C.
If using the stored procedure to execute multiple SQL statements, it's best to test run the stored procedure separately to size the compute resource first.
D.
Since task infrastructure is based on running the task body on schedule, it's recommended to configure the virtual warehouse for automatic concurrency handling using Multi-cluster warehouse (MCW) to match the task schedule
If using the stored procedure to execute multiple SQL statements, it's best to test run the stored procedure separately to size the compute resource first.

CREATE MATERIALIZED VIEW ON SCHEMA MYDB.MYSCHEMA TO USER1;
D.
