NEW QUESTION # 586
What is a User-Defined Table Function, or UDTF, used for in Snowflake?
Answer: C
Explanation:
The correct answer is A. To return a tabular value for each input row.
A User-Defined Table Function, or UDTF, returns a set of rows instead of a single scalar value. This is different from a scalar UDF, which returns one value for each input row.
Why A is correct:
A UDTF produces tabular output. It can return multiple rows and multiple columns, depending on how the function is defined.
Example concept:
SELECT *
FROM TABLE(my_udtf(input_column));
This syntax shows that the function result is treated like a table.
Why the other options are incorrect:
B). Returning a pandas Series is associated with vectorized Python UDF behavior, not the general definition of a UDTF.
C). Returning one output row as a single column or value describes a scalar UDF, not a table function.
D). Processing input rows as pandas DataFrames is associated with Snowpark Python and vectorized processing patterns, but it is not the basic Snowflake definition of a UDTF.
Official Snowflake documentation reference:
Snowflake documentation defines a UDTF as a user-defined function that returns tabular results. It can return multiple rows for each input row.
Reference: Snowflake Documentation - User-defined table functions; Snowflake Documentation - User- defined functions; SnowPro Core Study Guide - SQL and Snowflake Objects.

What is a characteristic of materialized views in Snowflake?
Answer: D
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.References:[COF-C02] SnowPro Core Certification Exam Study Guide

NEW QUESTION # 589
What is a key difference between the Snowflake CLI and SnowSQL?
Answer: A
Explanation:
The correct answer is B. Snowflake CLI is primarily used for managing workloads and applications, while SnowSQL is used for executing operations .
SnowSQL is Snowflake's command-line client that is primarily used to connect to Snowflake and execute SQL statements. It is commonly used for SQL operations, including running queries, loading data, unloading data, and executing scripts.
Snowflake CLI is a broader command-line tool designed for managing Snowflake workloads and application development workflows. It supports tasks related to Snowflake Native Apps, Snowpark, Streamlit, stages, tasks, and other development or deployment activities.
Why B is correct:
Snowflake CLI is more focused on managing Snowflake workloads, projects, and applications. SnowSQL is primarily used as a SQL command-line client to execute SQL operations against Snowflake.
Why the other options are incorrect:
A). This reverses the primary purposes of the tools. SnowSQL is not mainly for managing workloads and applications.
C). SnowSQL is not limited to DDL, and Snowflake CLI is not limited to DML.
D). Snowflake CLI is not limited to query execution, and SnowSQL is not a Python package management tool.
Official Snowflake documentation reference:
Snowflake documentation describes SnowSQL as the command-line client for connecting to Snowflake and executing SQL queries. Snowflake CLI is described as a command-line tool for developer workflows and managing Snowflake workloads and applications.
