Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q305-Q310):

質問 # 305
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 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.
C. 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.
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. 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.

正解：C

解説：
Extemal functions with API integrations are recommended for secure external API access. Using a service account for authentication is a best practice. Stored procedures allow for managed access control to consumer-provided tables. It is safer and allows for managed security. Option E combines these best practices for a secure and robust solution.

質問 # 306
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. Do not grant any privileges on the underlying tables to the 'application role' within the application package.
C. Grant "OWNERSHIP' on the views to the 'application role' within the application package.
D. Grant 'SELECT' privilege on the underlying tables to the 'application role' within the application package.
E. Use secure views to expose data, ensuring data access is controlled through the view's definition.

正解：A、E

解説：
The combination of granting ' SELECT only on the views (Option B) and using secure views (Option E) provides the strongest data security. Granting select on the views allows consumers to see the data you want them to see. Secure views prevent consumers from circumventing the view definition to access underlying tables, even if they had theoretical privileges (which they shouldn't). Not granting any privileges on tables(C) is correct in conjunction with (B&E), but on its own consumers will not see any data as they can't select from any object. Giving application role ownership to View(D) is not necessary to give consumer access to view the data.

質問 # 307
You are tasked with developing a Snowflake Native App that leverages a Partner provided secret using an external function which will send the processed data to their system. You plan to store the OAuth information to be used by the external function in a secret object managed by Snowflake. Which of the following steps are NECESSARY to ensure secure and correct setup of this app? Select all the options that apply.

A. Create a Secret object in Snowflake to store the OAuth token securely and reference it within the external function using 'SYSTEM$GET_SECRET function. Ensure proper access rights on the Secret object.
B. Grant the 'USAGE privilege on the API integration to the application role if the external function requires an API integration. GRANT USAGE ON API INTEGRATION TO APPLICATION ROLE
C. Grant the 'IMPORTED PRIVILEGES privilege on the database containing the Secret object to the application role. GRANT IMPORTED PRIVILEGES ON DATABASE TO APPLICATION ROLE '
D. Bypass storing the OAuth token in Snowflake and instead rely on passing it as a parameter to the external function from the consumer account, documented clearly for the consumer's security responsibilities.
E. Store the OAuth token directly within the external function's definition as a variable, ensuring it is encrypted using AES ENCRYPT before deployment.

正解：A、B、C

解説：
Storing the OAuth token directly in the function (A) is insecure. Passing the OAuth token from the consumer (E) is not a recommended practice. The correct approach is to use Snowflake's Secret object (B) to store the token securely. The application role needs 'IMPORTED PRIVILEGES on the database containing the secret (C) to access the secret. The 'USAGE privilege on the API integration(D) is also needed if the external function leverages an API integration.

質問 # 308
You are developing a Snowflake Native Application that provides a data enrichment service. This service requires the consumer to grant the application access to a specific table in their account. You want to ensure that upgrades to your application do not inadvertently break existing consumer configurations. You decide to use a versioned schem a. Which of the following steps are essential during the setup script execution to achieve this and maintain backward compatibility during future upgrades?

A. Create a versioned schema using 'CREATE SCHEMA VERSION = ' . Grant the application role 'USAGE on this versioned schema, and ensure all application logic references objects within this schema.
B. Create a secure view in the versioned schema that accesses the consumer's table. Grant the application role 'SELECT on this secure view. This provides a stable interface that isolates the application from direct changes to the consumer's table.
C. Create a new unversioned schema named 'APPLICATION' and install all application objects within it. This provides a consistent namespace for all consumers, regardless of the application version.
D. Define a custom role within the application package and grant it the necessary privileges to read the consumer's table via a secure view. Then, grant the application role the USAGE privilege on this custom role. This ensures that the application role can assume the custom role's privileges for data access.
E. Grant the application role 'OWNERSHIP on the consumer's table directly. This allows the application full control and ensures consistent data access regardless of future schema changes within the application.

正解：A、B

解説：
Options B and D are correct. Creating a versioned schema allows for managing changes in your application's data structures. By creating a secure view and granting the application role 'SELECT on it, you isolate your application from direct modifications to the consumer's table, ensuring backward compatibility. Option A is incorrect because an unversioned schema doesn't address the need for backward compatibility during upgrades. Option C is generally discouraged due to security concerns of granting ownership. Option E, while useful, is not the core reason to use a versioned schema to protect from consumer changes.

質問 # 309
You are developing a Snowflake Native Application for a data enrichment service and plan to list it on the Snowflake Marketplace. You want to control the costs incurred by consumers of your application while maximizing its accessibility. Which of the following strategies represent Snowflake Marketplace best practices for cost management and pricing?

A. Offer a free trial period with limited functionality to allow potential consumers to evaluate the application before committing to a paid subscription.
B. Provide detailed cost estimation documentation outlining the expected costs for different usage scenarios and data volumes.
C. Refrain from providing any cost-related information upfront to encourage broader adoption, deferring cost discussions until after installation and usage.
D. Implement a tiered pricing model based on data volume processed, compute resources consumed, or number of users accessing the application. Offer a free basic tier with limited functionality.
E. Use Snowflake's built-in resource monitors to proactively track application consumption and alert consumers when they approach predefined spending limits.

正解：A、B、D、E

解説：
Offering a free trial (A) allows users to evaluate. Tiered pricing (B) offers flexibility and accommodates different budgets. Providing cost estimation documentation (C) is transparent and helps users plan. Using resource monitors for alerts (E) enables proactive cost control. Hiding cost information (D) is not a best practice and can lead to negative user experiences and discourage adoption.
