Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q86-Q91):

質問 # 86
You are designing a Snowflake Native App that processes sensitive customer dat a. To comply with data residency requirements, you need to ensure the application processes data exclusively within the consumer's Snowflake account and does not transmit data outside.
Which features of the Snowflake Native App Framework support this requirement? (Select all that apply)

A. Snowflake Marketplace: Provides a secure and governed platform for distributing the application without requiring direct access to the consumer's account.
B. Secure Data Sharing: Allows the application to access data directly within the consumer's account without copying or moving it.
C. Application Packages: Package the entire application including code and configuration, ensuring data locality and not data transfer outside environment
D. Stored Procedures: Allows the application to execute custom logic within the consumer's Snowflake environment, processing data locally.
E. External Functions: Enables the application to call external services for data processing and enrichment, ensuring all data remains within the Snowflake environment.

正解：B、C、D

解説：
The correct answers are A, D and E. Secure Data Sharing enables direct access to data without movement. Stored Procedures execute logic within the consumer's environment. Application packages ensures everything within the consumer's environment. External Functions (B) inherently involve sending data outside of Snowflake, violating the residency requirement. Snowflake Marketplace (C) is about distribution and governance, not data processing location.

質問 # 87
You are developing a Snowflake Native App that provides data enrichment services to consumer accounts. The app requires access to both a secure internal API (accessible only within your provider account) and the consumer's data warehouse. Which of the following components and configurations are necessary to facilitate this access while adhering to Snowflake's security best practices?

A. A Stored Procedure defined in the application package that invokes the secure internal API via network rule with outbound traffic allowed only for the app, and utilizes a reader account to securely query the consumer s data with the use of SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES().
B. A UDF (User-Defined Function) defined in the application package that invokes the secure internal API using a secured API integration, and grants OWNERSHIP on it to the APPLICATION role. The consumer grants USAGE on their database to the application role.
C. A Java UDF defined in the application package uses JDBC connection to access a secure internal API endpoint. The consumer grants USAGE privilege to the application on their schemas.
D. A Python UDF defined in the application package that connects to the secure internal API using a secured API integration with allowed egress network policy that only allows connections from the app's deployment region. The consumer shares their database with the provider account through a data sharing arrangement.
E. A Snowpark function that leverages the SNOWFLAKCORE.AUTHZ.PASS PRIVILEGES() function with the application role executing the code. The app requires the consumer to create a shared secret to access their API.

正解：B

解説：
Option A is the most secure and correct approach. A UDF allows for encapsulated logic, a secured API integration handles authentication and authorization to the internal API, application role owns the function, and the consumer grants USAGE to the application, limiting access. Option B is less secure, reader account and SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES() are not required. Option C is flawed as data sharing is not the recommended way for native app to consume customer data. Option D - Java UDFs with JDBC is not best practice, not supported, not secure. Option E - shared secret and SNOWFLAKE.CORE.AUTHZ.PASS PRIVILEGES() are not the right approach.

質問 # 88
You're developing a Snowflake Native Application that stores user preferences in a table named 'USER PREFERENCES'. In version 1.0, this table only contained 'USER ID and 'THEME' columns. In version 2.0, you need to add a new 'LOCALE' column with a default value of 'en-CIS'. However, existing users should retain their existing preferences and not have the new 'LOCALE' column set to 'NULL'. Which of the following 'setup.sql' scripts correctly implements this requirement during the version upgrade?

正解：D

解説：
Option C is the correct answer. Adding the column with DEFAULT 'en-US' and using the IF NOT EXISTS check will prevent errors when upgrading a second time (or if the column was manually added previously). Setting a default value at the column definition level automatically populates the new column for existing rows when the column is added. Option A will accomplish the immediate objective, but doesn't account for repeated runs of the script. Options B and E will not check the column existence and result in an error, as well as will populate all rows with 'en-US'. Option D is redundantly updating to 'en-US', but it has the same issue as Option B, as it doesn't check column existence and result in an error.

質問 # 89
You are developing a Snowflake Native Application and want to implement comprehensive cost monitoring for your application's resource consumption within a consumer's Snowflake account. Which of the following approaches provide the MOST effective and granular cost visibility for both you (as the provider) and your consumers?

A. Utilize Snowflake's query history and function within your application to capture query execution statistics. Create views or tables to summarize resource consumption metrics for specific application components.
B. Combine Snowflake's query history (accessed via the ACCOUNT_USAGE schema) with custom tagging of resources and queries within your application. This allows you to attribute resource consumption to specific application features and provide detailed cost breakdowns for consumers.
C. Leverage Snowflake's Resource Monitor feature to set budget limits for the entire consumer account and receive alerts when these limits are exceeded. This provides a general overview of spending but lacks application-specific granularity.
D. Implement custom logging within your application to track resource usage (e.g., CPU time, data scanned) for each function or query. Aggregate and analyze these logs to generate cost reports for consumers.
E. Rely solely on Snowflake's global account-level cost dashboards and resource monitors to track overall Snowflake usage, including the resources consumed by your application. Analyze these dashboards manually to identify potential cost optimization opportunities.

正解：B

解説：
Option E provides the most granular and effective cost monitoring. Using Snowflake's query history from the ACCOUNT USAGE schema allows access to detailed resource consumption data. Combining this with custom tagging (e.g., using 'ALTER WAREHOUSE ... SET TAG allows associating specific queries and resources with your application and its features. This enables creating detailed cost breakdowns for consumers, showing exactly how much each feature is costing them. While B and C are useful, they require more manual effort and custom coding for aggregation. A and D lack application-specific detail. This allows for better chargeback, cost control and optimization.

質問 # 90
Your Snowflake Native App includes a JavaScript UDF that processes data from a secure view provided by the provider account. During consumer testing, the UDF fails with an 'Authorization error' even though the consumer has been granted the necessary USAGE privileges on the application package. What is the MOST likely cause of this error, and how can you resolve it within the context of a Snowflake Native App?

A. The secure view in the provider account has data masking policies applied that prevent the UDF from accessing the data. Remove the masking policies.
B. The application package needs to be explicitly authorized to access secure views in the provider account. This requires a manifest update and resubmission of the package.
C. The UDF is not declared as SECURE, preventing it from accessing objects in a different security context. Declare the UDF as SECURE.
D. The consumer lacks the necessary permissions on the underlying tables referenced by the secure view in the provider account. Grant the consumer direct access to these tables.
E. The consumer's role does not have the OWNERSHIP privilege on the application object. Assign the OWNERSHIP privilege to the consumer's role.

正解：C

解説：
The most likely cause is that the UDF needs to be declared as 'SECURE' (Option B). When a UDF accesses objects in a different security context (such as a secure view provided by the provider), it must be declared as SECURE to inherit the privileges of the caller (in this case, the application). This allows the UDF to access the data without requiring the consumer to have direct access to the underlying tables. A: Granting direct access to the underlying tables defeats the purpose of using a secure view and is generally not recommended. C: There is no explicit authorization needed in the manifest for a native app to access secure views if the secure UDF accesses the view D: While data masking policies could cause issues, the 'Authorization error' specifically points to a privilege problem, making the SECURE UDF the more likely culprit. E: The OWNERSHIP privilege on the application is not relevant to the UDF's ability to access data within the provider account.
