Snowflake SnowPro Specialty - Native Apps Sample Questions (Q70-Q75):

NEW QUESTION # 70
You are developing a Streamlit application within a Snowflake Native App that needs to access a custom Python module ('my_module.py') containing utility functions. The module resides in the same stage as your Streamlit application code. How would you ensure that the Streamlit application can correctly import and use this module?

A. Modify the ' PYTHONPATHS environment variable within the Snowflake environment to include the stage where 'my_module.py' is located.
B. Include in a 'requirements.txt' file and use 'pip install -r requirements.txt' within the Streamlit application's entrypoint script.
C. Place 'my_module.py' in the same directory as your main Streamlit application file. Snowflake automatically includes all files in the same directory when deploying the application.
D. Use the function to dynamically load 'my_module.py' directly from the stage, specifying the full stage path.
E. Use the method in your Streamlit application code to add the stage location to the Python module search path before importing my_module' .

Answer: E

Explanation:
The correct approach is to use 'sys.path.append()' (Option C) to add the stage location to the Python module search path. Snowflake Native Apps do not automatically include all files in the same directory (A), and modifying 'PYTHONPATH' (B) or using 'requirements.txt' and 'pip' (D) are not supported or necessary in this context. (E) could work but is unnecessarily complex compared to 'sys.path.append()' for modules within the same deployment package.

NEW QUESTION # 71
You are managing the release of a new version (v2.0) of your Snowflake Native Application that introduces significant schema changes to shared tables accessed by consumer accounts. To minimize disruption during the upgrade, you want to implement a phased rollout while ensuring backward compatibility for consumers who haven't yet upgraded. Which of the following strategies would allow you to achieve this goal effectively? (Select TWO)

A. Implement API versioning within your application code and provide compatibility layers to handle requests from consumers running older versions.
B. Create separate versions of the shared tables for vl .0 and v2.0, using views to present a unified interface. Grant consumer 'USAGE on view after upgrading.
C. Publish v2.0 without any schema changes and rely on consumers to manually migrate their data to new tables after upgrading.
D. Use dynamic SQL within stored procedures to conditionally access either the old or new schema based on the consumer's account ID, identified through a custom configuration table.
E. Create views on top of the new schema in v2.0 that emulate the old schema from vl .0. Grant consumers 'USAGE' on these views until they upgrade.

Answer: A,E

Explanation:
Options A and D are both viable strategies. Creating views on top of the new schema that emulate the old schema provides backward compatibility by maintaining the expected data structure for consumers who have not yet upgraded. Implementing API versioning within the application code allows you to handle requests from consumers running older versions, ensuring that their existing integrations continue to function. Option B introduces unnecessary complexity and performance overhead with dynamic SQL. Option C relies on manual data migration by consumers, which is prone to errors and delays. Option E doubles the storage requirements by creating separate table copies.

NEW QUESTION # 72
You are developing a Snowflake Native Application that utilizes Snowpark Container Services (SPCS). Your application requires a Compute Pool configured with autoscaling capabilities to handle fluctuating workloads. However, you want to minimize costs when the application is idle. Which of the following considerations are MOST important when defining the 'MIN NODES' and 'MAX NODES' parameters for your Compute Pool, along with the 'AUTO RESUME setting?

A. Compute Pool autoscaling is managed entirely by the underlying container orchestration system and Snowflake only provides basic resource allocation. The 'MIN NODES' and 'MAX NODES parameters are advisory only.
B. The optimal configuration depends on the balance between cost and performance. A higher 'MIN_NODES' value provides faster initial response times but incurs higher costs when idle. 'AUTO RESUME should be set to TRUE if you want the pool to automatically restart based on incoming requests.
C. Setting to 0 allows the Compute Pool to scale down completely when idle, eliminating costs. 'AUTO_RESUME should be set to TRUE to automatically start the pool when a new request is received.
D. The 'AUTO_RESUME parameter is irrelevant as the compute pool automatically scales based on current workload. should be set to the expected average workload.
E. Setting to a non-zero value ensures that some resources are always available, leading to faster response times for initial requests. 'AUTO RESUME' should be set to FALSE to prevent unnecessary resource usage.

Answer: B,C

Explanation:
Setting to 0 allows the pool to scale down completely, saving costs when idle. 'AUTO_RESUME' is crucial for automatically restarting the pool when needed. The optimal balance depends on specific application needs; a higher 'MIN NODES' improves initial response time but increases idle costs. Therefore, understanding this trade-off is crucial. AUTO RESUME is important for native application. MIN_NODES controls costs and response time.

NEW QUESTION # 73
You are building a Snowflake Native App that needs to store configuration settings specific to each consumer account. These settings will influence the behavior of the application. Which of the following methods is the MOST secure and recommended approach for managing these configuration settings within the Snowflake Native App Framework?

A. Use external configuration files stored in an Amazon S3 bucket and accessed via external functions. This provides flexibility and scalability.
B. Store the configuration settings directly within the application's code. This allows for easy access and modification during development.
C. Store the configuration settings in a public database table within the application's share. This makes the settings easily accessible to all consumers.
D. Utilize parameters defined in the 'setup.sql' script and accessible via SQL commands like 'SYSTEM$GET APP PARAMETER. This allows consumers to configure the application during installation.
E. Hardcode the configuration settings directly into the manifest file as environment variables.

Answer: D

NEW QUESTION # 74
An application provider wants to grant usage privileges on a warehouse named 'APP WAREHOUSE to a consumer account so their application can use the warehouse's compute resources. Which of the following SQL statements would correctly accomplish this goal, ensuring only the necessary privileges are granted to the consumer's application role 'APP ROLE?

Answer: A

Explanation:
The correct statement is 'GRANT USAGE ON WAREHOUSE APP_WAREHOUSE TO APPLICATION ROLE APP_ROLE;'. This grants the application role the necessary privilege to use the warehouse for compute. 'GRANT ALL PRIVILEGES' is too broad and grants unnecessary permissions. Granting to a ROLE' (Option C) instead of an 'APPLICATION ROLE' is incorrect for granting privileges to a Native Application. 'OPERATE and 'MONITOR are not valid privileges for warehouses in this context; only 'USAGE is typically required for an application to utilize a warehouse.
