Snowflake SnowPro Core Certification Exam Sample Questions (Q229-Q234):

NEW QUESTION # 229
What Snowflake objects can contain custom application logic written in JavaScript? (Select TWO)

Answer: B,E

Explanation:
Snowflake allows users to write custom application logic in JavaScript for two types of objects: Stored Procedures and User-Defined Functions (UDFs).
* Stored Procedures:Snowflake stored procedures can be written in JavaScript to encapsulate complex business logic and procedural operations.
CREATE OR REPLACE PROCEDURE my_procedure()
RETURNS STRING
LANGUAGE JAVASCRIPT
EXECUTE AS CALLER
AS
$$
// JavaScript logic here
$$;
* User-Defined Functions (UDFs):Snowflake UDFs can be written in JavaScript to perform custom calculations or operations on data.
CREATE OR REPLACE FUNCTION my_function(x FLOAT)
RETURNS FLOAT
LANGUAGE JAVASCRIPT
AS
$$
return x * 2;
$$;
References:
* Snowflake Documentation: Stored Procedures
* Snowflake Documentation: User-Defined Functions (UDFs)


NEW QUESTION # 230
Which statement accurately describes Snowflake's architecture?

Answer: A

Explanation:
Snowflake's architecture is unique in that it combines elements of both traditional shared-disk and shared-nothing database architectures. This hybrid approach allows Snowflake to offer the scalability and performance benefits of a shared-nothing architecture (with compute and storage separated) while maintaining the simplicity and flexibility of a shared-disk architecture in managing data across all nodes in the system.
This results in an architecture that provides on-demand scalability, both vertically and horizontally, without sacrificing performance or data cohesion.

* Snowflake Documentation: Snowflake Architecture


NEW QUESTION # 231
Which views are included in the data_sharing_usage schema? (Select TWO).

Answer: C,E

Explanation:
https://docs.snowflake.com/en/sql-reference/data-sharing-usage


NEW QUESTION # 232
Which of the following objects are contained within a schema? (Choose two.)

Answer: B,E


NEW QUESTION # 233
When would a user use the GET command?

Answer: A

Explanation:
The correct answer is A. A staged file needs to be unloaded to a local machine .
The Snowflake GET command is used to download files from an internal Snowflake stage to a local file system. It is commonly used after data has been unloaded from a table into an internal stage and the user wants to retrieve those staged files locally.
Why A is correct:
The GET command downloads files from a Snowflake internal stage to a local directory.
Example:
GET @my_stage file:///tmp/data/;
This command downloads files from the internal stage @my_stage to the local /tmp/data/ directory.
Why the other options are incorrect:
B). Loading a local file onto a stage is done with the PUT command, not GET.
C). Opening query results in a third-party tool is not the purpose of the GET command.
D). Permanently deleting files from a Snowflake stage is done with the REMOVE command, not GET.
Official Snowflake documentation reference:
Snowflake documentation describes the GET command as the command used to download data files from a Snowflake stage to a local directory or folder.
Reference: Snowflake Documentation - GET command; Snowflake Documentation - PUT command; Snowflake Documentation - REMOVE command; SnowPro Core Study Guide - Data Loading and Unloading.
