Snowflake NAS-C01 Exam Syllabus Topics:

Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application that processes sensitive customer dat a. The application needs to comply with data residency requirements in both the EU (Frankfurt) and the US (Virginia). You have decided to use Snowflake's multi-region capabilities for failover and regulatory compliance. You plan to install the application in both regions. What considerations are MOST critical when designing your application's installation process to ensure data locality and business continuity?

A) Prioritize replicating application code over replicating application data products, as the code is more critical for application functionality.
B) Use Snowflake's replication features to replicate the application package and its associated data products between the regions.
C) Configure Snowflake's cross-cloud auto-failover capabilities to automatically switch to the secondary region in case of a primary region failure. This requires Enterprise Edition or higher.
D) Implement a custom error handling mechanism within the application to automatically retry failed operations in the other region in case of a regional outage.
E) Ensure the application package contains region-specific configuration files for each region, allowing the application to connect to the correct regional data stores.

2. You are packaging a Snowflake Native App and need to ensure that consumer accounts can only access specific data views you've created within your application schem a. You want to prevent consumers from directly querying the underlying tables. Which of the following security measures, when implemented together, BEST achieve this objective? (Choose two)

A) Grant 'SELECT privilege only on the views to the 'application role' within the application package.
B) Use secure views to expose data, ensuring data access is controlled through the view's definition.
C) Do not grant any privileges on the underlying tables to the 'application role' within the application package.
D) Grant "OWNERSHIP' on the views to the 'application role' within the application package.
E) Grant 'SELECT' privilege on the underlying tables to the 'application role' within the application package.

3. A Native Application provider has created a database named 'app_db' using 'CREATE DATABASE app_db WITH MANAGED ACCESS;'. They now need to create a secure view that exposes a subset of data from an underlying table 'sensitive_data' within the schema 'internal_schema' of 'app_db' to a consumer's role named 'consumer role'. They wish to minimize data exposure while adhering to managed access principles. Which set of SQL statements represents the MOST secure and correct approach?

A) CREATE OR REPLACE SECURE VIEW app_db.internal_schema.consumer_view AS SELECT coll , c012 FROM app_db.internal_schema.sensitive_data; GRANT SELECT ON VIEW TO ROLE consumer_role;
B) CREATE OR REPLACE SECURE VIEW app_db.internal_schema.consumer_view AS SELECT coll , c012 FROM app_db.internal_schema.sensitive_data; GRANT ALL PRIVILEGES ON VIEW TO ROLE consumer_role;
C) CREATE VIEW app_db.internal_schema.consumer_view AS SELECT coll , c012 FROM app_db.internal_schema.sensitive_data; GRANT SELECT ON VIEW app_db.internal_schema.consumer_view TO ROLE consumer_role;
D) CREATE OR REPLACE SECURE VIEW app_db.internal_schema.consumer_view AS SELECT coll , c012 FROM app_db.internal_schema.sensitive_data; GRANT SELECT ON VIEW TO ROLE consumer_role; REVOKE ALL PRIVILEGES ON VIEW app_db.internal_schema.consumer_view FROM ROLE PUBLIC;
E) CREATE OR REPLACE VIEW app_db.internal_schema.consumer_view AS SELECT coll , c012 FROM app_db.internal_schema.sensitive_data; GRANT ALL PRIVILEGES ON VIEW TO ROLE consumer_role;

4. A financial services company is developing a Snowflake Native App. It needs to securely access external market data via an API and store the processed results in a consumer-provided table. Considering security best practices and the Snowflake Native App Framework limitations, which of the following approaches represents the MOST secure and recommended implementation for this scenario?

A) Use a Snowflake external function with an API integration, configured with a service account that has the necessary permissions to access the API. Store the processed data in a consumer-provided table using stored procedures and INSERT statements using the application role.
B) Utilize a Java UDF with the 'network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer- provided table by using the application role with INSERT privilege granted by consumer.
C) Utilize a Python UDF with the 'external network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer-provided table by using the application role. API key is stored in snowflake secret.
D) Use a Snowflake external function with an API integration that passes the API key as a parameter. Store the processed data in a consumer-provided table using dynamic SQL.
E) Employ a Snowflake external function, configured with a service account, which invokes an API integration stored in the provider account. The external function returns the data, which is then inserted into a consumer-owned table using a stored procedure and INSERT statements, where the application role has been granted the necessary INSERT privilege.

5. A Snowflake Native App developer is creating a new application database. They need to ensure that only the application itself and designated roles within the provider account can access the database. Which of the following CREATE DATABASE statements would BEST achieve this, adhering to best practices for application isolation and security?

A)

B)

C)

D)

E)
