Answer: D

Explanation:

In Snowflake, tag inheritance is a feature that allows tags, which are key-value pairs assigned to objects for the purpose of data governance and metadata management, to be inherited within a hierarchy. The hierarchy in which tag inheritance is possible is from Schema to Table to Column. This means that a tag applied to a schema can be inherited by the tables within that schema, and a tag applied to a table can be inherited by the columns within that table.

Answer: B

Explanation:

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.

========================

Answer: A

Explanation:

The correct answer is A. SECURITYADMIN.

In Snowflake's default role hierarchy, the SECURITYADMIN role is responsible for managing security-related objects and grants. This role is granted the global MANAGE GRANTS privilege, which allows it to manage object grants across the account.

Why A is correct:

SECURITYADMIN is the built-in role designed to manage users, roles, and grants. By default, it has the ability to grant and revoke privileges.

Why the other options are incorrect:

B . USERADMIN is used primarily for user and role management, but it does not have the same broad default grant management authority as SECURITYADMIN.

C . SYSADMIN is typically used to create and manage account objects such as warehouses, databases, schemas, and tables, but it is not the default security grant administrator.

D . PUBLIC is automatically granted to every user and should not be used for administrative grant management.

Official Snowflake documentation reference:

Snowflake documentation describes SECURITYADMIN as the role that manages grants globally and inherits the privileges of USERADMIN. It includes the MANAGE GRANTS privilege by default.
