최신 SnowPro Core Certification NAS-C01 무료샘플문제 (Q360-Q365):

질문 # 360
You are developing a Snowflake Native Application that provides data enrichment services. You want to offer tiered pricing based on the number of API calls made by consumers. Which of the following is the most effective approach to implement usage-based billing and track API call consumption within your application?

A. Utilize Snowflake's events table to capture API call events based on function executions, enabling precise tracking and reporting of API usage for each consumer.
B. Use Snowflake's resource monitors to limit the compute resources available to consumers based on their chosen tier.
C. Leverage Snowflake's built-in metering framework using and 'SYSTEM$METER STAGE_STORAGE BYTES' to indirectly estimate API calls.
D. Implement a UDF within the application that increments a counter in a shared table each time an API endpoint is called. Query this table to determine usage.
E. Implement a custom logging mechanism within the application to track API calls and store the logs in a separate Snowflake database, accessible only to the provider. Use scheduled tasks to analyze these logs and generate billing data.

정답：D

설명：
Option A is the most effective as it directly tracks API calls within the application. Resource monitors (B) only control compute costs, not API usage. System$METER functions (C) track storage, notAPl calls. Custom logs (D) introduce complexity and security concerns. Snowflake's events table is a good general approach (E), but requires enabling detailed logging, which has performance implications and might not be available in all accounts. A shared table with a UDF provides the most direct and controllable way to meter usage.

질문 # 361
You are developing a Snowflake Native Application that utilizes a Streamlit frontend. The application requires access to specific data in the consumer account. You've already defined the necessary roles in your provider account. Which of the following steps are absolutely necessary to grant the Streamlit application the appropriate permissions to access the consumer's data? Assume the provider account has already shared the application package.

A. Within the application package installation script, grant the necessary privileges (e.g., 'SELECT on tables) directly to the 'APPLICATION' object representing the installed application using 'GRANT ON TO APPLICATION In the consumer account, no further privilege grants are required. Also ensure to 'GRANT APPLICATION ROLE app_public TO APPLICATION'
B. In the consumer account, grant the 'IMPORTED PRIVILEGES privilege on the application package to a role that Streamlit will assume. Ensure the Streamlit application has code to execute 'snowflake.connector.connect()' with the correct consumer account credentials.
C. In the consumer account, create a new application role and grant the necessary privileges (e.g., 'SELECT on tables) to this role. In the Streamlit code, use streamlit.experimental_get_query_params()' to pass the role name as a query parameter to the application.
D. Create a new database role in the provider account and grant the necessary privileges (e.g., 'SELECT on tables) to this role. Share this database role to the consumer account using secure data sharing. No code changes are needed in the Streamlit application.
E. Define an application role in the application package and grant the necessary privileges within the package installation script using 'GRANT APPLICATION ROLE TO SHARE. In the consumer account, grant the application role to a user. No code changes are needed in the Streamlit application. Ensure to also grant the application role to the application in the install script with 'GRANT APPLICATION ROLE TO APPLICATION

정답：A,E

설명：
Options C and E are the most accurate. Option C is correct because it leverages application roles, which are the recommended way to manage privileges in Snowflake Native Apps. Granting the application role to a user in the consumer account allows them to access the data via the application. Option E is correct because granting privileges directly to the 'APPLICATION' object is essential for the application to function correctly with its own access rights. Additionally, granting 'app_public' ensures basic functionality is available to the application. Option A is incorrect because applications should not be connecting to the database using standard connectors with explicit credentials in Native Apps. Option B is incorrect because passing role names as query parameters is not a secure or recommended practice. Option D is incorrect because sharing a database role directly is not the appropriate mechanism for granting access within a Snowflake Native App. The application package and its associated roles should manage the access.

질문 # 362
You are developing a Snowflake Native Application that uses a UDF (User-Defined Function) to process dat a. The UDF needs to be updated with new logic to handle a specific edge case. You want to ensure a smooth transition for existing consumers of your application. Which of the following strategies should you consider to avoid breaking changes? (Select TWO)

A. Remove the existing UDF and provide instructions for consumers to recreate it with the new logic.
B. Modify the existing UDF in place and notify consumers about the change after deployment.
C. Package new version and then call patch method.
D. Create a new UDF with a different name, implement the new logic, and update the application to use the new UDF, while keeping the old UDF for backward compatibility.
E. Implement versioning within the existing UDF to handle the new logic based on a version parameter passed by the consumer.

정답：D,E

설명：
Options B and C provide strategies to avoid breaking changes. Creating a new UDF (B) allows existing consumers to continue using the old UDF while new consumers can use the updated one. Implementing versioning within the existing UDF (C) allows the UDF to behave differently based on the version parameter, providing backward compatibility. A and D are disruptive, and E is vague and unspecific.

질문 # 363
A Native App developer is using Snowflake's Event Tables for tracing the execution of their application. They have noticed a significant performance overhead when event logging is enabled, particularly for high-volume UDFs. Which of the following strategies would be MOST effective in mitigating the performance impact of event logging while still capturing valuable tracing information?

A. Write event data directly to an external cloud storage system (e.g., AWS S3, Azure Blob Storage) bypassing Snowflake's Event Tables altogether.
B. Reduce the number of columns captured in the event tables to minimize the amount of data being written. Store all tracing data in a single large event table to simplify querying.
C. Implement sampling or conditional logging within the UDFs, only logging events for a subset of executions or when specific conditions are met. Utilize asynchronous logging techniques where appropriate to offload logging operations.
D. Disable event logging entirely for high-volume UDFs to eliminate the performance overhead.
E. Increase the frequency of event table flushes to reduce the number of events buffered in memory. This minimizes memory pressure and write latency.

정답：C

설명：
Option C offers the best balance between performance and valuable tracing information. Sampling allows you to reduce the volume of events logged, while conditional logging ensures that only relevant events are captured. Asynchronous logging further minimizes the performance impact. Option A is not desirable as it eliminates tracing altogether. Option B will not reduce overhead. Option D is a good strategy but doesn't address high logging volumes. Option E may not be compliant or possible.

질문 # 364
A company is developing a Snowflake Native Application that will be distributed through the Snowflake Marketplace. The application uses internal stages to store intermediate data processing results. Which of the following methods is the MOST secure and recommended way to manage the application's internal stages?

A. Create an internal stage owned by the ACCOUNTADMIN role and grant usage to the application database role.
B. Create an internal stage owned by the application database role and grant usage to all roles within the application.
C. Create an internal stage owned by a custom role created specifically for stage management within the application, granting only necessary permissions.
D. Create an external stage in AWS S3 or Azure Blob Storage and grant access to the application database role.
E. Create an internal stage owned by the application database role. The application framework automatically grants necessary permissions.

정답：C

설명：
Creating a custom role specifically for stage management and granting only the necessary permissions (such as READ and WRITE) follows the principle of least privilege and enhances security. The ACCOUNTADMIN role is overly privileged. Relying on the application framework to automatically grant permissions may not provide sufficient control. External stages introduce dependencies and require managing external credentials. The database role may not be granular enough; a dedicated role is more secure.
