Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q349-Q354):

質問 # 349
A Snowflake Native App developer wants to externalize certain configuration values so that a consumer can adjust the app's behavior without modifying the app's code directly. Which of the following methods is the MOST appropriate for achieving this using the Snowflake Native App Framework?

A. Using Snowflake variables and setting them at the session level.
B. Using dynamic SQL to modify the application code at runtime based on environment variables.
C. Storing the configuration values in a separate Snowflake table within the consumer account.
D. Hardcoding the configuration values directly into the SQL code.
E. Defining parameters in the manifest file and using them within the application code.

正解：E

解説：
Defining parameters in the manifest file is the most appropriate way to externalize configuration values in a Snowflake Native App. This allows the consumer to set these parameters during installation or upgrade, effectively tailoring the app's behavior without needing to modify the underlying code. Hardcoding values is inflexible, session variables are not persistent for the app, using a separate table adds unnecessary complexity, and dynamic SQL for code modification is generally discouraged for security and maintainability reasons.

質問 # 350
You are developing a Snowflake Native Application that includes a TASK which calls a stored procedure. The stored procedure interacts with an external API using an external function. The external function is defined with an API integration. To ensure secure access to the external API, how should the privileges be granted so that the TASK can execute successfully and access the external function within the consumer account?

A. Grant USAGE privilege on the API integration to the 'app_public' role and no specific privilege on the TASK, as task execution is implicitly granted.
B. Grant USAGE privilege on the API integration to the 'application' role and EXECUTE TASK privilege on the TASK to the 'app_public' role.
C. Grant OWNERSHIP on the API integration and EXECUTE TASK privilege on the TASK to the 'app_public' role.
D. Grant USAGE privilege on the API integration and EXECUTE TASK privilege on the TASK to the 'app_owner' role.
E. Grant USAGE privilege on the API integration and EXECUTE TASK privilege on the TASK to the 'app_public' role.

正解：E

解説：
For the TASK to successfully call the stored procedure which in turn calls the external function using API integration, the 'app_public' role needs 'USAGE privilege on the API integration and 'EXECUTE TASK privilege on the TASK. The 'app_owner' role is typically used for managing the application and not for executing tasks in the consumer account. The 'application' role doesn't exist in the context of native apps in this sense. Granting USAGE on API integration allows application to use the integration. Granting execute on task, enables the task to be executed.

質問 # 351
You are designing a Snowflake Native App that relies on a specific version of a shared library. You want to ensure that your application continues to function correctly even if the provider of the shared library releases a new, incompatible version. How can you achieve version isolation for your application's dependencies within the Snowflake Native App Framework?

A. Utilize Snowflake's 'API_INTEGRATION' to create endpoint where you have version control for the shared library.
B. Leverage Snowflake's dependency management system to specify a version range for the shared library in your application's setup script.
C. Utilize the ' feature to directly link your application to a specific version of the shared library hosted in an external repository.
D. Implement a custom version compatibility check within your application code to gracefully handle potential incompatibilities with newer versions of the shared library.
E. Package the required version of the shared library directly within your application's code bundle, ensuring it is isolated from any external updates.

正解：E

解説：
Packaging the required version of the shared library directly within your application's code bundle (B) provides the most reliable version isolation. This ensures that your application always uses the version it was designed for, regardless of any external updates. While options A, C, D, and E are valid approaches in other contexts, they do not provide the same level of isolation within the Snowflake Native App Framework. Snowflake Native Apps do not utilize for this purpose, nor do they have a specific dependency management system like option C. Version checking (D) is a good practice but doesn't prevent the application from being affected by the newer version. Using SAPI INTEGRATION' would not provide version control.

質問 # 352
You are developing a Snowflake Native Application that provides data enrichment services. You want to implement a phased rollout of a new version to your users. You have three distinct user groups: 'EarlyAdopters', 'StandardUsers', and 'CriticalUsers'. You need to use release directives to manage the upgrade process, ensuring that 'EarlyAdopters' receive the new version first, followed by 'StandardUsers' after a week of monitoring, and finally 'CriticalUsers' two weeks after that. Which of the following approaches is the MOST effective way to achieve this using Snowflake Native App release directives?

A. Create separate application packages for each user group and manage versions independently within each package.
B. Use release directives within a single application package to control version availability based on the application role. Create separate roles for each user group and grant them appropriate privileges.
C. Implement a custom upgrade mechanism within your application logic, querying a configuration table to determine which version each user should receive. This table is updated based on a predefined schedule.
D. Use release directives with tag-based versioning. Tag each user account with a tag indicating their user group (e.g., 'user_group = 'EarlyAdopters"). Then, use the 'STAGE_VERSIONS' clause in the 'ALTER APPLICATION' command to associate versions with these tags, specifying a different activation time for each tag. For example: 'ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'EarlyAdopters' ACTIVATE_AT = '2024-01-01 00:00:00'; ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'StandardUserS ACTIVATE_AT = '2024-01-08 00:00:00';'
E. Use the SALTER APPLICATION' command with the 'STAGE VERSIONS clause to explicitly assign specific versions to each user group based on their tag values. For example: 'ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'EarlyAdopters';'

正解：D

解説：
Option E is the most effective and recommended approach. Release directives, combined with tag-based versioning, provide a built-in mechanism for managing phased rollouts. This allows you to target specific user groups based on their tags and control the activation time for each version, ensuring a controlled and monitored upgrade process. Option A is not efficient as it increases management overhead. Option B is not correct since it does not support ACTIVATE_AT option. Option C will not allow gradual release as it tied to application role. Option D needs to implement a custom upgrade logic. Snowflake tag based versioning is the recommended option.

質問 # 353
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. The consumer has not refreshed their application instance metadata. Ask the consumer to execute SYSTEM$REFRESH_EXTERNAL_FUNCTIONS() in the application database.
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. Event sharing is inherently unreliable and Snowflake does not guarantee event delivery. The provider should implement alternative polling mechanisms.
D. 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().
E. 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.

正解：D、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.
