Snowflake Updated SOL-C01 Exam Questions and Answers by abbie

Snowflake’s foundational security capability isalways-on end-to-end encryption, applied to all customer data both at rest and in transit. Snowflake encrypts data stored in micro-partitions using AES-256, and all network communication uses TLS encryption. Key management is automated through Snowflake’s hierarchical key model, providing additional rotation, rekeying, and defense-in-depth mechanisms.

While RBAC, masking policies, and network policies are crucial components of Snowflake security, encryption is the platform’s guaranteed, baseline, mandatory protection feature. It applies universally to all data, regardless of workload, role configuration, or user settings.

Option A: automated masking is optional and policy-driven, not a primary universal mechanism.

Option B: network perimeter defense exists but is not the platform’s core foundation.

Option C: RBAC controls access but does not protect data itself.

Thus, Snowflake’s primary and most universal security capability is end-to-end encryption.

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

A virtual warehouse in Snowflake is acompute resourcethat supplies CPU, memory, and temporary storage used to process SQL queries, perform data loading, execute DML operations, and run procedural logic. Warehouses are elastic, can be resized on demand, suspended to save costs, and automatically resumed when needed.

Virtual warehouses donotstore data—data is kept in Snowflake’s centralized storage layer. They also are not user accounts; user accounts belong to Snowflake’s identity management system. Worksheets are UI components in Snowsight or Classic Console used to write and run SQL, not compute resources.

Thus, virtual warehouses are Snowflake's compute engine, enabling all processing without managing physical infrastructure.

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

To create a new schema in Snowsight, users must follow the hierarchical navigation of Snowflake’s object structure. The correct sequence is:

Data → Database → Create Schema

Steps:

Open theDatatab in the left navigation.

Select aDatabasewhere the schema will be created.

ChooseCreate → Schema.

Enter the schema name and (optionally) description.

ClickCreate.

Incorrect options:

“Add Data” is used for loading files, not creating schema objects.

“Data → Create Schema” is incomplete because Snowflake must knowwhich databasethe schema belongs to.

“Data Product” is unrelated to object creation.

Thus, Snowflake requires explicit database context before schema creation.

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

The USE SCHEMA command sets the active schema context for the current session. After it is executed, any unqualified object names (for example, SELECT * FROM my_table) are resolved within that schema. This reduces the need to fully qualify object names with database and schema each time and ensures that statements reference the expected logical container.

CREATE SCHEMA is used to create a new schema. ALTER SCHEMA and GRANT OWNERSHIP are used to modify schema properties or transfer ownership, respectively. USE SCHEMA does not alter structure or ownership; it simply changes the context in which subsequent SQL statements are interpreted.
