Snowflake COF-C03 Questions Answers

The correct answer is B. Copilot provides assistance when creating and interpreting queries .

Snowflake Copilot is an AI-assisted feature that helps users work with Snowflake more efficiently. It can assist with writing SQL, understanding queries, and interpreting query-related information.

Why B is correct:

Copilot is designed to help users create, refine, and understand SQL queries using natural language assistance.

Why the other options are incorrect:

A. Query optimization is primarily handled by Snowflake’s optimizer and performance features, not Copilot.

C. Copilot does not automatically rewrite table schemas based on inferred data patterns.

D. Copilot is not primarily a feature for executing stored procedures from prompts.

Official Snowflake documentation reference:

Snowflake documentation describes Snowflake Copilot as an AI assistant for helping users generate, understand, and work with SQL and Snowflake data workflows.

The correct answer is B. The role will lose access to objects that are not granted to the updated role .

Snowflake access control is based on privileges granted to roles. Users receive access to objects through the active role and any inherited roles in the role hierarchy. If privileges are revoked from a role, that role no longer has those privileges unless they are still inherited through another granted role.

Why B is correct:

When privileges are removed from a role, users using that role lose the ability to perform actions that depended on the revoked privileges. Access is controlled by the current set of grants assigned to the role.

Why the other options are incorrect:

A. A role does not retain revoked privileges until a new session starts. Revoked privileges affect access according to Snowflake access control rules.

C. The user does not need to reissue USE ROLE just because privileges were revoked.

D. Snowflake does not terminate active sessions simply because a privilege is removed from a role.

Official Snowflake documentation reference:

Snowflake documentation explains that privileges are granted to roles, roles are granted to users or other roles, and revoking privileges removes the ability to perform the associated actions unless access exists through another role path.

The correct answer is D. Create a secure view .

A secure view is the recommended and efficient way to share a filtered subset of data with a consumer account using Snowflake Secure Data Sharing. The provider can define the rows and columns that should be visible, then share the secure view instead of sharing the full base table.

Why D is correct:

A secure view protects the view definition from unauthorized users and can be used to expose only selected rows or columns from an underlying table.

Example concept:

CREATE SECURE VIEW shared_sales_west AS

SELECT order_id, customer_id, amount, region

FROM sales

WHERE region = ' WEST ' ;

The provider can then include this secure view in a share, allowing the consumer to query only the approved subset of data.

Why the other options are incorrect:

A. A secure UDF can protect function logic, but it is not the most efficient method for sharing a subset of table data.

B. A dynamic table materializes transformation results, but it is not the standard method for secure data sharing with filtered access.

C. An external table allows querying data in external cloud storage. It is not the best method for sharing a subset of Snowflake table data.

Official Snowflake documentation reference:

Snowflake documentation explains that secure views are used with Secure Data Sharing when a provider wants to share filtered or restricted data while protecting the underlying query definition.
