What is a characteristic of materialized views in Snowflake?

Materialized views do not allow joins.
Materialized views do not allow joins.
Clones of materialized views can be created directly by the user.
Clones of materialized views can be created directly by the user.
Multiple tables can be joined in the underlying query of a materialized view.
Multiple tables can be joined in the underlying query of a materialized view.
Aggregate functions can be used as window functions in materialized views.
Aggregate functions can be used as window functions in materialized views.
Suggested answer: C

Explanation:

One of the characteristics of materialized views in Snowflake is that they allow multiple tables to be joined in the underlying query.This enables the pre-computation of complex queries involving joins, which can significantly improve the performance of subsequent queries that access the materialized view4.Reference:[COF-C02] SnowPro Core Certification Exam Study Guide

How should clustering be used to optimize the performance of queries that run on a very large table?

Manually re-cluster the table regularly.

Choose one high cardinality column as the clustering key.
Choose one high cardinality column as the clustering key.
Use the column that is most-frequently used in query select clauses as the clustering key.
Use the column that is most-frequently used in query select clauses as the clustering key.
Assess the average table depth to identify how clustering is impacting the query.
Assess the average table depth to identify how clustering is impacting the query.
Suggested answer: B

Explanation:

For optimizing the performance of queries that run on a very large table, it is recommended to choose one high cardinality column as the clustering key.This helps to co-locate similar rows in the same micro-partitions, improving scan efficiency in queries by skipping data that does not match filtering predicates4.

What step can reduce data spilling in Snowflake?

Using a larger virtual warehouse
Using a larger virtual warehouse
Increasing the virtual warehouse maximum timeout limit
Increasing the virtual warehouse maximum timeout limit
Increasing the amount of remote storage for the virtual warehouse
Increasing the amount of remote storage for the virtual warehouse
Using a common table expression (CTE) instead of a temporary table
Using a common table expression (CTE) instead of a temporary table
Suggested answer: A

Explanation:

To reduce data spilling in Snowflake, using a larger virtual warehouse is effective because it provides more memory and local disk space, which can accommodate larger data operations and minimize the need to spill data to disk or remote storage1.

Which solution improves the performance of point lookup queries that return a small number of rows from large tables using highly selective filters?

Automatic clustering
Automatic clustering
Materialized views
Materialized views
Query acceleration service
Query acceleration service
Search optimization service
Search optimization service
Suggested answer: D

Explanation:

The search optimization service improves the performance of point lookup queries on large tables by using selective filters to quickly return a small number of rows.It creates an optimized data structure that helps in pruning the micro-partitions that do not contain the queried values3.

Explanation:

Temporary tables do not consume any storage costs in Snowflake because they only exist for the duration of the session that created them and are automatically dropped when the session ends, thus incurring no long-term storage charges4.
