Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q187-Q192):

質問 # 187
A data science company is developing a Snowflake Native App that provides advanced fraud detection for financial institutions. The app requires secure access to sensitive transaction data within the consumer's Snowflake account. Which of the following approaches BEST aligns with Snowflake's recommended practices for managing data access and securing data within a Native App?

A. The app should use secure views created by the consumer that grant the app read-only access to only the specific transaction data needed for fraud detection.
B. The app should directly access tables containing transaction data using the consumer's own service account credentials, which are securely stored within the app's code.
C. The app should request full ACCOUNTADMIN privileges in the consumer account to access all necessary data for fraud detection.
D. The app should create and manage its own temporary tables in the consumer account and load transaction data into them for processing.
E. The app should directly access transaction data through data sharing from provider account.

正解：A

解説：
Using secure views is the best approach. Secure views allow the consumer to control precisely whatdata the application can access without granting overly broad permissions. This minimizes the risk of unintended data exposure and adheres to the principle of least privilege. ACCOUNTADMIN is excessive and insecure. Storing credentials is also insecure and against best practices. Creating temporary tables and loading data duplicates data and can be inefficient.

質問 # 188
A provider is developing a Snowflake Native App and utilizes event sharing to communicate state changes to consumers. After initial installation, a consumer reports not receiving any event notifications. The provider has verified the event table is populated correctly. Which of the following are the MOST likely reasons for this issue and how can the provider troubleshoot them?

A. Event sharing is inherently unreliable and Snowflake does not guarantee event delivery. The provider should implement alternative polling mechanisms.
B. The consumer's event table function does not have the correct security invoker privileges. Grant EXECUTE TASK on the event table function to the consumer role.
C. The consumer has not explicitly granted the necessary privileges on the event table function to the role used by the app. Instruct the consumer to grant USAGE on the event table function to the app role.
D. The consumer has not refreshed their application instance metadata. Ask the consumer to execute SYSTEM$REFRESH_EXTERNAL_FUNCTIONS() in the application database.
E. The event table function is not correctly filtering events based on the consumer's application instance I Review the function logic to ensure proper filtering using APP_INSTANCE_ID().

正解：C、E

解説：
B and D are the most likely reasons. B: The consumer needs to grant USAGE on the event table function to the application role. D: The event table function must correctly filter events using APP INSTANCE_ID() to ensure the consumer only receives events related to their instance. A is incorrect because the consumer (not provider) needs to grant usage. C is incorrect as SYSTEM$REFRESH EXTERNAL FUNCTIONS() is not the correct procedure in this context. E is wrong. Snowflake guarantees event delivery, assuming correct setup.

質問 # 189
You are developing a Snowflake Native App that processes streaming data from a Kafka topic. The app needs to continuously ingest data, perform real-time transformations, and store the results in a Snowflake table within the app's managed database. Which Snowflake feature(s) and approach(es) are BEST suited for implementing this data ingestion and processing pipeline within the Native App?

A. Use a Snowflake Stream to capture changes in the Kafka topic and then use a Snowflake Task to periodically merge these changes into the target table.
B. Employ a combination of Snowflake Snowpipe Streaming for data ingestion and Dynamic Tables for continuous, incremental data transformations within the application's managed database.
C. Leverage Snowflake Snowpipe Streaming to ingest data directly from the Kafka topic into the target table, combined with Snowflake Tasks to handle any required data transformations.
D. Use Snowflake Pipes to continuously ingest data from the Kafka topic into a staging table and then use stored procedures to periodically transform and load the data into the target table.
E. Implement a custom Kafka consumer within a Java User-Defined Function (UDF) to read data from the Kafka topic and directly insert it into the target table.

正解：B

解説：
Snowpipe Streaming offers the lowest latency and near real-time data ingestion capabilities. Dynamic Tables provide a declarative and managed way to perform continuous data transformations, making them ideal for processing streaming data within a Snowflake Native App. Options A, B, and C are less suitable for high-velocity streaming data due to latency and complexity concerns. Streams are for tracking changes within Snowflake tables, not external Kafka topics.

質問 # 190
A Snowflake Native App provider is using a Snowpark Python UDF to process data before writing it to an event table for consumption by consumer applications. The UDF fails intermittently with a 'Java heap space' error. Which of the following strategies are MOST effective in mitigating this error?

A. Increase the warehouse size used by the consumer application instance, as this controls the memory available to the UDF during event processing.
B. Optimize the Python UDF code to use more memory-efficient data structures and algorithms, reducing overall memory consumption.
C. Configure the event table function to use a larger warehouse size using the EXECUTE AS OWNER clause.
D. Switch to a Java UDF instead of a Python UDF, as Java UDFs inherently have better memory management in Snowflake.
E. Implement batch processing within the UDF to process data in smaller chunks, reducing the memory footprint at any given time.

正解：B、E

解説：
B and D are correct. B: Batch processing avoids loading the entire dataset into memory at once. D: Optimizing the code to be memory-efficient directly addresses the root cause. A is incorrect as warehouse size for the consumer application is not the controling factor for UDF event processing. C is incorrect because the warehouse size of the provider application instance controls UDF size, not consumer warehouse size. E is incorrect because switching the UDF language doesn't fundamentally solve the memory problem if the underlying code is still inefficient.

質問 # 191
An application provider, 'SecureData Solutions', wants to implement an in-app share within their Snowflake Native App. They intend to share a specific, filtered subset of a provider-owned table with consumers to enhance app functionality without exposing the entire dataset. Which of the following steps are REQUIRED to properly configure and utilize this in-app share?

A. Create a secure view on the provider-owned table with the desired filters, create a share in the provider account, grant usage on the database and schema containing the secure view to the share, and then grant SELECT privilege on the secure view directly to the share. Lastly, grant OWNERSHIP on the SHARE to the application role.
B. Create a secure view on the provider-owned table with the desired filters, create a database role in the provider account, grant SELECT privilege on the secure view to this database role, create a share, and grant usage to the role. Lastly, grant OWNERSHIP on the SHARE to the application role.
C. Create a database role in the provider account, grant SELECT privilege on the base table to the role, then create a SHARE and add the role to the SHARE as a privileged principal.
D. Create a share in the provider account, grant usage on the database and schema containing the table to the share, and then grant SELECT privilege on the filtered view of the table directly to the share.
E. Create a database role in the provider account, grant SELECT privilege on the filtered view of the table to this database role, and then create a share and grant usage to this role.

正解：A

解説：
In-app sharing requires using secure views for filtering. A share is created, and usage rights on the database and schema containing the secure view must be granted to the share. Then, SELECT privilege on the secure view is granted to the share directly. Finally, OWNERSHIP on the SHARE is granted to the application role. Database Roles cannot be directly be granted to share, as shares need access to concrete securable objects, views or tables.
