Snowflake SOL-C01 Dumps Questions Answers

The SELECT * statement instructs Snowflake to returnall columnsfrom the referenced table or view. This is commonly used during data exploration, debugging, initial data profiling, and validation steps. It allows users to quickly view the complete dataset structure without manually specifying each column name.

However, while SELECT * retrieves all columns, it does not limit the number of rows. To restrict rows, developers must include aLIMITclause (e.g., SELECT * FROM table LIMIT 10;).

The query does not automatically apply DISTINCT or primary key filtering—Snowflake returns all rows exactly as stored unless additional filtering, WHERE conditions, or ordering are provided.

Though SELECT * is convenient, Snowflake best practices recommend explicitly selecting columns in production workloads to optimize performance and avoid unnecessary scanning of unused fields.

Snowflake includes severalsystem-defined RBAC rolesto provide structured access control across the platform.

ACCOUNTADMINis the highest-privileged role, governing the entire account, including billing, replication, failover groups, and object ownership inheritance.

SECURITYADMINis responsible for user, role, and privilege management, including granting and revoking roles, password policies, and MFA enforcement. It is essential for identity lifecycle governance.

USERADMINmanages user creation, role creation, and user authentication administration. It is commonly assigned to identity administrators.

CUSTOM_ROLEis not a Snowflake system role; it is a user-created role, allowing organizations to design fine-grained, domain-specific access policies.

These predefined roles form the foundation of Snowflake’s security model and support least-privilege implementations.

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

Snowflake uses a Role-Based Access Control (RBAC) model, whererolesare the containers of privileges. Assigning roles to users ensures that permissions on database objects (such as tables, schemas, warehouses, and functions) are enforced consistently and securely. Users do not receive privileges directly; instead, privileges are granted to roles, and roles are assigned to users.

This enables scalable, auditable, and manageable access control.

Roles do not determine tasks, do not affect query optimization, and do not govern which data types a user may query—permissions are object-based, not datatype-based.
