Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q45-Q50):

質問 # 45
You are developing a Snowflake Native Application that uses Streamlit to provide a user interface for data analysts. The application accesses sensitive customer data residing in a managed database. To enhance security, you want to implement row-level security (RLS) based on the user's role. You have the following Streamlit code snippet:

Which of the following actions should you take to implement RLS in the Snowflake Native App, ensuring only authorized users can view specific rows of 'customer_data'? Assume the already contains necessary credentials. Choose the most secure and efficient method.

A. Use Snowflake's masking policies combined with a secure view. The masking policy reveals data based on the user's role. Grant the Streamlit application's role access to the secure view.
B. Implement RLS directly within the Streamlit application by filtering the 'data' DataFrame based on the user's role before displaying it using 'st.dataframe'. Store user roles in a separate table and fetch them using a different database connection.
C. Implement a custom Python decorator that checks user roles before executing the 'get_data' function. Raise an exception if the user lacks the necessary role.
D. Create a secure view in Snowflake that implements RLS based on the role of the user executing the query. Grant the Streamlit user access to this view instead of the base table, and modify the 'get_data' function to query the view.
E. Modify the SQL query within the 'get_data' function to include a 'WHERE clause that filters data based on the current Streamlit user's username obtained using 'st.session_state.user.username' .

正解：A

解説：
Using Snowflake's masking policies and secure views is the most secure and efficient method. It centralizes RLS within Snowflake, leveraging its security features. Option A is vulnerable to SQL injection if 'st.session_state.user.username' is not properly sanitized. Option B is better, but masking policies provide more granular control and data obfuscation. Option C pushes security logic to the application layer, which is less secure. Option E adds unnecessary complexity and overhead.

質問 # 46
You are developing a Snowflake Native Application that requires access to an external API to enrich data within the consumer's account. You need to implement secure authentication and authorization to this external API. Which of the following methods provide the MOST secure and compliant approach for storing and managing the API credentials within your Snowflake Native Application package, while minimizing the risk of exposure to the consumer?

A. Store the API credentials as a secret within Snowflake's Secret Management feature, referencing the secret from within your application's functions. Grant access to the secret through the application role.
B. Store the API credentials in a secure configuration table within your application package, encrypted using a symmetric key managed by Snowflake's KMS.
C. Store the API credentials as plain text within the setup script, as this script is only executed once during installation and is not accessible to consumers.
D. Store the API credentials as environment variables within the Snowflake function code that calls the API. These variables are automatically encrypted by Snowflake.
E. Prompt the consumer to provide the API credentials during the application installation process, storing them in a secure configuration table within their account and referencing them from your application through secure views.

正解：A

解説：
Using Snowflake's Secret Management is the recommended approach for securely storing and managing sensitive credentials. Storing the credentials as a secret and granting access via application role ensures that only authorized code within the application can access the credentials. Storing as plain text is a major security risk. Environment variables (while encrypted) aren't best practice for long-term credential storage. Prompting the consumer relies on them to securely manage the credentials.

質問 # 47
You are developing a Snowflake Native Application that processes sensitive dat a. During the application lifecycle management, including version updates, what steps should you take to ensure the data security and privacy of the consumers' data, especially considering that your development team might need access to a subset of the data for testing?

A. Utilize Snowflake's external functions to process the data in a secure enclave outside of Snowflake, minimizing the risk of data exposure. Ensure external functions called are encrypted.
B. Implement data masking and anonymization techniques to create a sanitized test dataset derived from the consumer's data. Provide the development team with access only to the masked data, via data sharing from the producer to consumer account.
C. Grant the development team direct access to the consumer's data warehouse to facilitate testing. Ensure proper auditing is enabled.
D. Create a separate Snowflake account for testing and populate it with synthetic data that mimics the structure and characteristics of the consumer's data.
E. Use Snowflake's data classification features to identify sensitive data and implement row-level security to restrict access to the development team.

正解：B、D

解説：
The best answers are (B) and (D). Providing direct access to consumer data (A) is a major security risk. Option (B) utilizes masking/anonymization, crucial for protecting sensitive data. Data is shared from Producer account to Consumer accounts with masking policies applied for developers testing/access. Option (D) with synthetic data offers a secure testing environment. While data classification (C) and row-level security are useful, they aren't sufficient to protect data during development and testing, as developers could still potentially access sensitive data. External functions (E) could be used in conjunction with options B or D, but aren't a standalone solution.

質問 # 48
You are developing a Snowflake Native Application that uses Snowpark Container Services. Your application consists of multiple containerized services that require varying levels of computational resources. You want to optimize resource utilization and minimize costs by using a single Compute Pool for all services, while ensuring that each service has guaranteed access to resources. Which of the following strategies and SQL commands (or configurations) can be used to achieve this?

A. Use a single Compute Pool, create separate user-defined functions (UDFs) for each service and control resource allocation using the 'RESOURCE MONITOR parameter for each UDF.
B. Use a single Compute Pool and rely on the container orchestration system to dynamically allocate resources among the services. Monitor utilization and adjust the Compute Pool size as needed. No SQL commands are needed.
C. Create separate Compute Pools for each service, sizing each pool according to the service's peak resource requirements.
D. Create a resource monitor and assign it to the COMPUTE POOL to manage cost. Resource monitors cannot be used to granular control the compute pool usage for native applications.
E. Create a single Compute Pool and configure resource quotas for each service using container orchestration-specific configurations (e.g., Kubernetes resource quotas). While not directly managed via SQL, proper configuration of the container orchestrator is required.

正解：B、E

解説：
Option B is valid because the underlying container orchestration system dynamically allocates resources. Option C is also valid because resources can be configured in container orchestration systems to achieve resource guarantees for each service. Creating separate compute pools may be costly and inefficient in terms of resource management. Resource Monitors are for cost control not fine-grained service-level resource management. It provides control to monitor cost. The correct configuration of the container orchestrator is critical to achieve desired outcomes.

質問 # 49
You are developing a Snowflake Native App that allows consumers to configure certain parameters through a setup page. You want to persist these configurations securely. What is the recommended approach to store and retrieve consumer-specific configuration data within a Snowflake Native App?

A. Utilize the 'APPLICATION_SETTINGS' object to store and retrieve configuration parameters. Access these settings within your application logic.
B. Store the configuration data in a consumer-specific stage created during app installation.
C. Store the configuration data in a secured view provided by the provider and accessible to the consumer.
D. Store the configuration data as environment variables within the application package.
E. Create a dedicated configuration table within the consumer's Snowflake account using the setup script and use secure UDFs to access it.

正解：A

解説：
The recommended approach is to use the 'APPLICATION_SETTINGS' object (Option E). Snowflake provides this mechanism specifically for storing and retrieving consumer-specific configuration data securely within a Native App. 'APPLICATION SETTINGS' allows providers to define configurable parameters that consumers can set during installation or later through a setup interface. These settings are securely managed by Snowflake and accessible within the application's logic using Javascript or SQL. Other options are not recommended for the following reasons: A: Environment variables are not consumer-specific and are generally used for application-wide settings, not per-consumer configurations. B: Storing configuration data in a consumer-specific stage is not secure or recommended, as it bypasses Snowflake's built-in security mechanisms. C: Creating tables directly in the consumer's account requires additional permissions and can be more complex to manage. D: Secured views are generally intended for data sharing, not for storing configuration parameters.
