Free Snowflake COF-C02 Exam Actual Questions

Note: Premium Questions for COF-C02 were last updated On Mar. 13, 2026 (see below)

Question #1

Which Snowflake SQL statement would be used to determine which users and roles have access to a role called MY_ROLE?

Reveal Solution Hide Solution
Correct Answer: B

The SQL statementSHOW GRANTS TO ROLE MY_ROLEis used to determine which users and roles have access to a role called MY_ROLE. This statement lists all the privileges granted to the role, including which roles and users can assume MY_ROLE.References:[COF-C02] SnowPro Core Certification Exam Study Guide


Question #2

What is the MINIMUM permission needed to access a file URL from an external stage?

Reveal Solution Hide Solution
Correct Answer: D

To access a file URL from an external stage in Snowflake, the minimum permission required is USAGE on the stage object. USAGE permission allows a user to reference the stage in SQL commands, necessary for actions like listing files or loading data from the stage, but does not permit the user to alter or drop the stage.

References:

Snowflake Documentation: Access Control


Question #3

What happens when a network policy includes values that appear in both the allowed and blocked IP address list?

Reveal Solution Hide Solution
Correct Answer: B

In Snowflake, when setting up a network policy that specifies both allowed and blocked IP address lists, if an IP address appears in both lists, access from that IP address will be denied. The reason is that Snowflake prioritizes security, and the presence of an IP address in the blocked list indicates it should not be allowed regardless of its presence in the allowed list. This ensures that access controls remain stringent and that any potentially unsafe IP addresses are not inadvertently permitted access.

References:

Snowflake Documentation: Network Policies


Question #4

What are common issues found by using the Query Profile? (Choose two.)

Reveal Solution Hide Solution
Correct Answer: D, E

The Query Profile in Snowflake is used to identify performance issues with queries. Common issues that can be found using the Query Profile include identifying inefficient micro-partition pruning (D) and data spilling to a local or remote disk (E).Micro-partition pruning is related to the efficiency of query execution, and data spilling occurs when the memory is insufficient, causing the query to write data to disk, which can slow down the query performance1.


Question #5

Which system_defined Snowflake role has permission to rename an account and specify whether the original URL can be used to access the renamed account?

Reveal Solution Hide Solution
Correct Answer: A

The ACCOUNTADMIN role in Snowflake has the highest level of privileges, including the ability to manage accounts, users, roles, and all objects within the account. This role is specifically granted the permission to rename an account and specify whether the original URL can be used to access the renamed account. The ACCOUNTADMIN role encompasses broad administrative capabilities, ensuring that users assigned this role can perform critical account management tasks.
