Snowflake SnowPro Specialty - Native Apps Sample Questions (Q335-Q340):

NEW QUESTION # 335
When designing the architecture of a Snowflake Native App, which of the following architectural considerations and trade-offs should you carefully evaluate to optimize performance, security, and cost-effectiveness? (Select all that apply)

A. Using secured API integration to call the external APIs to get real time details in the app to make the app more useful.
B. Implementing robust error handling and logging mechanisms to facilitate debugging and monitoring of the application's behavior in both the provider and consumer environments.
C. Choosing the appropriate data access model (e.g., UDFs, stored procedures, Snowpark) based on the specific use case and performance requirements, considering the overhead associated with each approach.
D. Storing all application data within the provider account and accessing it directly from the consumer account using data sharing to avoid data duplication.
E. Minimizing data transfer between the provider and consumer accounts by leveraging Snowpark and UDFs for data processing within the consumer's environment.

Answer: B,C,E

Explanation:
Options A, D, and E are crucial for optimal Snowflake Native App design. Minimizing data transfer (A) reduces costs and improves performance. Robust error handling and logging (D) are essential for debugging and monitoring. Choosing the correct data access model (E) is a key performance factor. Option B is incorrect because storing all data in the provider account and sharing to the consumer introduces unnecessary dependencies and potential security risks. Consumers also need to pay for querying your shared data. Option C is not always desirable, since calling external API every time would be too expensive.

NEW QUESTION # 336
You are creating a Snowflake Native Application that will be distributed to consumer accounts. As part of the installation process, you need to ensure that a specific database role, 'DATA READER, is created in the consumer account and granted 'SELECT' privileges on a specific table in the consumer's shared dat a. Which of the following code snippets, when placed within the application's setup script (install.sql), will correctly achieve this, assuming the application is granted 'CREATE DATABASE ROLE?

Answer: D

Explanation:
Option D correctly creates the database role, grants the necessary privileges, and associates it with the application. Here's a breakdown: 'CREATE OR REPLACE DATABASE ROLE DATA_READER;': creates or replaces the database role 'DATA_READER in the consumer account. 'GRANT SELECT ON TABLE CONSUMER DB.PUBLIC.MY TABLE TO DATABASE ROLE DATA READER;': Grants the 'SELECT privilege on the specified table to the 'DATA_READER role. It assumes that already exists in the consumer account through data sharing or some other mechanism. 'GRANT DATABASE ROLE DATA READER TO APPLICATION ROLE app_public;': This grants the database role to the application role, making the database role available to the application via the 'app_public' application role. 'GRANT APPLICATION ROLE app_public TO APPLICATION This is essential. This makes sure the application has the privileges from the application role granted. Without this, the database role is effectively useless to the application. In the consumer account, this means it will be able to use application. It should have an application object representing installed app in Consumer Account. Option A is incorrect because granting to 'SHARE is not the appropriate way to grant the role to the application. This is meant for granting to other accounts. Option B is incorrect because application will not be able to use app_public if not granted. Option C is incorrect because you need to assign database role to application role so it can be properly managed at the application level. You also need to grant the application role to the applicatiom Option E is incorrect because you should not grant the application role to SHARE; it will provide access to any accounts using the share, and can lead to over-privileged access.

NEW QUESTION # 337
You are developing a Snowflake Native Application that processes sensitive customer dat a. You need to ensure that the application is secure and compliant with data privacy regulations. Which of the following security measures are MOST effective when designing your application package? (Select TWO)

A. Store all sensitive data in external stages managed by the provider account to isolate it from the consumer's Snowflake environment.
B. Implement role-based access control (RBAC) to restrict access to sensitive data based on user roles within the application.
C. Encrypt all data at rest and in transit using Snowflake's built-in encryption features.
D. Use obfuscation techniques on the data within the application, making it harder to be read.
E. Bypass Snowflake's RBAC and authentication to manage access within the application.

Answer: B,C

Explanation:
Encrypting data at rest and in transit (A) is crucial for protecting sensitive information. Implementing RBAC (B) ensures that only authorized users can access specific data, enhancing security and compliance. Storing data in provider-managed external stages (C) would not allow consumer access to the data via Snowflake's data sharing capabilities. Obfuscation(D) is not the strongest mechanism. Bypassing Snowflake's RBAC(E) is a security risk and should never be done.

NEW QUESTION # 338
You are developing a Snowflake Native Application that provides data transformation services. You want to provide example SQL scripts to consumers within the application package to showcase how to use the application's functions. Where should these example scripts be stored to ensure they are accessible to consumers upon installation?

A. Store the example SQL scripts as files within the application package itself (e.g., in a 'scripts' directory) and use relative paths to access them from within the application code.
B. Store the example SQL scripts in a table within the application database and provide a view to access them.
C. Store the example SQL scripts in a separate stage within the provider account and grant USAGE on the stage to the application role.
D. Store the example SQL scripts in an external stage (e.g., AWS S3) and provide instructions to the consumer to load them.
E. Embed the example SQL scripts directly as string literals within the setup script.

Answer: A

Explanation:
Storing the scripts within the application package (Option B) ensures that they are always available to the consumer as part of the application installation. Relative paths allow the application code to access them directly. Option A requires additional permissions setup. Option C is not suitable, it is not meant for storage of scripts like that. Option D makes the setup script excessively long and hard to maintaim Option E requires additional setup and is not self-contained.

NEW QUESTION # 339
You are developing a Snowflake Native Application that includes a Streamlit UI. The application needs to read configuration parameters such as API keys and database connection strings. Which of the following methods are the recommended and secure ways to manage these configuration parameters within a Snowflake Native App?

A. Use Streamlit secrets Cst.secretS) configured within the Streamlit application's settings in Snowflake. Store sensitive information like API keys and database credentials there.
B. Store the configuration parameters directly within the Streamlit code as Python variables.
C. Store configuration parameters in an external file (e.g., a JSON or YAML file) and include it in the application's deployment package. Read the file from the Streamlit application.
D. Store the configuration parameters in a dedicated table within the Snowflake managed database and read them using SQL queries from the Streamlit application. Grant appropriate privileges to the Streamlit application's role on this table.
E. Store the configuration parameters as environment variables within the Snowflake environment where the Streamlit application is running.

Answer: A,D

Explanation:
Options B and C are the recommended methods. Using Streamlit secrets Cst.secretS) allows secure storage of sensitive information within the Snowflake environment. Storing the configuration parameters in a dedicated table within the Snowflake managed database with appropriate permissions is another secure and controllable method. Storing directly in code (A) or external files (E) poses security risks. Environment variables (D), while sometimes used, are less manageable and secure in this specific Snowflake Native App context. Option B offers greater control over who can read the config data through role based access control. Option C allows separation of code and configuration without putting parameters in a table that can accidentally be queried and seen.
