Snowflake SnowPro Specialty - Native Apps Sample Questions (Q332-Q337):

NEW QUESTION # 332
You are designing a Snowflake Native Application that requires granular control over the privileges granted to different application roles. You want to follow the principle of least privilege. You have the following requirements: Application roles , and app_read_only'. What is the most effective strategy to implement this using definer's rights?

A. Grant all privileges on all application objects to the 'app_admin' role and rely on the consumer to manage privilege inheritance for other roles.
B. Create separate schemas for each application role, placing objects with different privileges into these schemas. Then, grant the appropriate privileges on each schema to the corresponding application role.
C. Create stored procedures owned by the application, with each stored procedure explicitly granting the required privileges to the corresponding role. Consumers must then grant USAGE on these procedures to their desired roles.
D. Create views for each application role, granting SELECT privilege on the necessary tables to each view. Then, grant SELECT privilege on the appropriate view to each application role.
E. Create stored procedures owned by the application, with each stored procedure performing actions within the app. Grant OWNERSHIP on each stored procedure to the application admin. Consumers must then grant USAGE on these procedures to their desired roles.

Answer: C

Explanation:
Using stored procedures owned by the application and using DEFINER's rights offers the most granular control and aligns with the least privilege principle. The application provider defines the privileges within the stored procedures. The consumer only needs to grant USAGE on the stored procedures. Creating views or separate schemas can work, but they add complexity. Granting all privileges to the 'app_admin' role is too permissive and doesn't adhere to the principle of least privilege.

NEW QUESTION # 333
You are designing a Snowflake Native Application that involves data sharing with consumers. You want to leverage a custom Python library 'data_transform.py' within your application package to perform specific data transformations on the shared data before it is accessed by consumers. This library contains sensitive logic and should not be directly visible or accessible by the consumer. Which of the following is the MOST secure and appropriate way to package and utilize this 'data_transform.py' library?

A. Publish 'data_transform.py' as a public Python package on Anaconda and have consumers install it in their Snowflake environment.
B. Package 'data_transform.py' as a user-defined function (UDF) and grant 'USAGE privilege on the UDF to the consumer's role.
C. Include directly within your application package's source code and call its functions from within your application's procedures. Grant necessary privileges on the procedures to the consumer's role, ensuring to only expose the procedures and never the python source.
D. Store 'data_transform.py' as an internal stage file and read it dynamically into your application's Python code at runtime.
E. Embed the contents of 'data_transform.py' directly within the application's stored procedure code as a multi-line string.

Answer: C

Explanation:
The most secure and appropriate way to package and utilize the custom library is to include it directly within your application package's source code and call its functions from within your application's procedures. This approach ensures that the library's sensitive logic remains encapsulated within your application and is not directly visible or accessible by the consumer. Only expose stored procedures with defined permissions and never the underlaying source code. Options A, UDFs, can be a way to expose code but also requires direct granting of USAGE which is not ideal. Option C, storing as an internal stage file, adds complexity and does not inherently improve security. Option D exposes code publicly, thus, this is incorrect. Option E can be hard to maintain.

NEW QUESTION # 334
You are developing a Snowflake Native Application that connects to an external API to enrich dat a. To comply with best practices and maintain security posture of your Native App, you decide to manage the API Key as Secret. Which of the following approach are needed to ensure that the Snowflake Native application can securely access the secret?

A. Store the API Key directly within the application code, encrypting it using AES encryption with a key managed by Snowflake.
B. Store the API Key as an environment variable within the application container.
C. Store the API key using Snowflake's secret management feature and the 'USAGE' privilege to the application's invoker's rights role.
D. Create a secure UDF that retrieves the API Key from an external key management system and grant USAGE privilege on UDF to the application role.
E. Store the API Key as a Secret within Snowflake and grant USAGE privilege on the secret to the application role.

Answer: C,E

Explanation:
Snowflake's secret management feature with appropriate privilege grants is the recommended approach. Storing the API Key as a Secret (A & E) within Snowflake and granting 'USAGE privilege to the appropriate role (Application role or invoker's rights role) ensures secure access. Embedding the key directly in code (B) or as an environment variable (D) is insecure. While a UDF retrieving the key (C) could work, it adds complexity and potential performance overhead compared to using Snowflake's native secret management.

NEW QUESTION # 335
You are developing a Native App on Snowflake that needs to interact with an external REST API. To ensure proper security, you want to store the API key securely within the application package and use it for authentication. Which of the following is the MOST secure and RECOMMENDED method to accomplish this?

A. Store the API key in a secure stage with encryption and grant SELECT privilege to the application role.
B. Store the API key as a secret using Snowflake's Secret Management feature and reference it within a secure UDE
C. Hardcode the API key directly into the application code within a UDF (User-Defined Function).
D. Create a key-pair stored procedure. Storing the API key as a secret, then decrypting the key during each API call.
E. Store the API key in a table within the application database with minimal access control, relying on Snowflake's data encryption at rest.

Answer: B

Explanation:
Snowflake's Secret Management offers the most secure way to store and manage sensitive information like API keys. It allows you to store secrets securely and reference them within UDFs, preventing direct exposure. Options A, B and D introduce security risks by storing the API key in less secure ways or directly in code. Option E introduces unnessary complexity.

NEW QUESTION # 336
You are developing a Streamlit application within a Snowflake Native Application that needs to access a secured view named 'sensitive_data' in the application's container. This view exposes aggregated and anonymized dat a. What minimum set of privileges must be granted to the 'app_public' application role to allow users to query this view from the Streamlit application?

A. GRANT USAGE ON DATABASE .application TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
B. GRANT USAGE ON SCHEMA application TO APPLICATION ROLE app_public; GRANT ALL PRIVILEGES ON VIEW application.sensitive_data TO APPLICATION ROLE app_public;
C. GRANT USAGE ON DATABASE TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
D. GRANT USAGE ON SCHEMA application TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
E. GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;

Answer: D

Explanation:
The correct answer is B. To access a view, you need 'SELECT privilege on the view itself and USAGE privilege on the schema containing the view. 'APPLICATION' schema is the automatically generated schema, and should be used. Option A is incorrect because the USAGE privilege should be granted on the schema, not the database. Option C is incorrect because the USAGE privilege is needed on the schema, not just the database. Option D is incorrect because granting ALL PRIVILEGES is generally not a best practice for security and not needed. Option E is incorrect because you must grant usage on the Schema.
