Snowflake SnowPro Core Certification Exam Sample Questions (Q603-Q608):

NEW QUESTION # 603
How are network policies defined in Snowflake?

A. They are a set of rules that dictate how Snowflake accounts can be used between multiple users.
B. They are a set of rules that define how data can be transferred between different Snowflake accounts within an organization.
C. They are a set of rules that define the network routes within Snowflake.
D. They are a set of rules that control access to Snowflake accounts by specifying the IP addresses or ranges of IP addresses that are allowed to connect

Answer: D

Explanation:
to Snowflake.
Explanation:
Network policies in Snowflake are defined as a set of rules that manage the network-level access to Snowflake accounts. These rules specify which IP addresses or IP ranges are permitted to connect to Snowflake, enhancing the security of Snowflake accounts by preventing unauthorized access. Network policies are an essential aspect of Snowflake's security model, allowing administrators to enforce access controls based on network locations.

Snowflake Documentation: Network Policies

NEW QUESTION # 604
A Snowflake user is trying to load a 125 GB file using SnowSQL. The file continues to load for almost an entire day. What will happen at the 2< hour mark?

A. The tile will slop loading and all data up to that point will be committed.
B. The file loading could be aborted without any portion of the file being committed.
C. The file's number of allowable hours to load can be programmatically controlled to load easily into Snowflake
D. The file will continue to load until all contents arc loaded.

Answer: B

Explanation:
When attempting to load large files, such as a 125 GB file, into Snowflake using SnowSQL, the process might encounter limitations related to the maximum execution time for queries or data loading operations. If the loading process exceeds this time limit (typically around 24 hours), it could be aborted without committing any part of the file to the database. This behavior is designed to prevent indefinite resource consumption and to maintain system stability, emphasizing the need for optimizing data load operations, possibly through file segmentation or parallel loading strategies.

NEW QUESTION # 605
Which command is used when loading data with Snowpipe?

A. MERGE
B. INSERT
C. COPY
D. UPDATE

Answer: C

Explanation:
The correct answer is B. COPY .
Snowpipe loads data using a pipe object. The pipe definition contains a COPY INTO < table > statement that tells Snowflake how to load staged files into a target table.
Why B is correct:
Snowpipe automates loading staged files, but the actual load operation is still based on the COPY INTO < table > command.
Example:
CREATE PIPE my_pipe
AS
COPY INTO my_table
FROM @my_stage
FILE_FORMAT = (TYPE = CSV);
Why the other options are incorrect:
A). INSERT adds rows manually or through query results, but Snowpipe does not use INSERT as its load command.
C). UPDATE modifies existing rows and is not used by Snowpipe for loading files.
D). MERGE performs insert/update/delete logic based on matching conditions, but Snowpipe uses COPY INTO < table > for file ingestion.
Official Snowflake documentation reference:
Snowflake documentation explains that a pipe defines a COPY INTO < table > statement used by Snowpipe to load data from staged files.
Reference: Snowflake Documentation - Snowpipe; Snowflake Documentation - CREATE PIPE; Snowflake Documentation - COPY INTO < table > ; SnowPro Core Study Guide - Data Loading and Unloading.
