Snowflake SnowPro Specialty - Native Apps Sample Questions (Q251-Q256):

NEW QUESTION # 251
You are packaging a Snowflake Native App that includes a file. During the packaging process, you encounter an error stating that a required Python package, 'pandas', is not found. However, you have included a 'requirements.txt' file in the application bundle with 'pandas' listed as a dependency. What is the MOST likely cause of this error, and what steps can you take to resolve it?

A. Snowflake automatically installs all packages listed in 'requirements.txt' when the application is packaged, so the issue must lie elsewhere, such as a typo in the package name.
B. The 'requirements.txt' file needs to be converted to a 'setup.py' file for Snowflake to recognize the dependencies correctly.
C. The 'requirements.txt' file is not being correctly processed by the Snowflake Native App build system. Ensure the file is in the root directory of the application bundle and is properly formatted.
D. Snowflake does not automatically install packages from 'requirements.txt' during packaging. You must manually upload the pandas package to a Snowflake stage and import it within your 'streamlit.py' file.

Answer: C

Explanation:
The most likely cause is that the 'requirements.txt' file is either not in the correct location (root directory of the application bundle) or is improperly formatted. Snowflake expects the file to be in the root and follows standard Python dependency declaration syntax. While Snowflake provides mechanisms for dependency management, properly placing and formatting the 'requirements.txt' is fundamental. Options stating that Snowflake automatically handles everything or requires manual uploads are incorrect or incomplete. Option E is not the most likely scenario, since it would require more configurations and more things to go wrong (hence less likely).

NEW QUESTION # 252
Which of the following statements regarding warehouse sizing and configuration for a Snowflake Native Application are true?

A. The parameter determines if the warehouse is used for data loading vs query processing.
B. The 'AUTO SUSPEND' parameter controls how long a warehouse remains active after executing queries, impacting cost.
C. The 'MAX CONCURRENCY LEVEL' parameter helps manage the number of queries that can be executed concurrently on the warehouse.
D. Warehouse size cannot be changed after it is created.
E. A larger warehouse size always guarantees faster query execution, regardless of the query's characteristics.

Answer: B,C

Explanation:
Warehouse size can be changed after creation using 'ALTER WAREHOUSE statement. A larger warehouse is not always faster; it depends on the query's design and data volume. The 'AUTO SUSPEND' parameter is crucial for cost control as it determines the idle time before automatic suspension. While Snowflake has virtual warehouses, the ' WAREHOUSE_TYPE parameter doesn't exist. 'MAX CONCURRENCY LEVEL' is essential for managing concurrent queries and preventing resource contention, improving overall application performance.

NEW QUESTION # 253
You are packaging a Snowflake Native App that includes a Streamlit application for data visualization. The Streamlit application needs to access a table named 'SALES DATA within the app's data container. Which of the following steps are REQUIRED to correctly grant the Streamlit application the necessary permissions to read the data? (Select all that apply)

A. Grant the 'IMPORTED PRIVILEGES' on the database containing the 'SALES DATA' table to the application role.
B. Create a service account within the Snowflake Native App and grant the 'SELECT' privilege on the 'SALES_DATR table to the service account.
C. Grant the 'SELECT privilege on the 'SALES_DATX table directly to the application role defined in the setup script.
D. Create a secure view on the ' SALES_DATX table, using the function in the view definition, and grant the 'SELECT privilege on the secure view to the application role.
E. Grant the 'APPLOG' privilege to the application role defined in the setup script on the internal stage.

Answer: B,D

Explanation:
Snowflake Native Apps require service accounts for components like Streamlit to interact with data securely. Granting SELECT directly to the app role (D) is generally not how applications are structured with secure views. APPLOG (B) is related to logging, not data access. IMPORTED PRIVILEGES (E) is useful when referencing objects from external data sources which is not the case here, the table resides within the applications data container. Using a secure view (C) allows for controlled access and data masking if needed and service account will be used to access it.

NEW QUESTION # 254
A data provider is building a Snowflake Native Application that provides real-time stock market data through a Snowflake Marketplace listing. They have implemented a secure data sharing mechanism. To update the data in the listing with minimal downtime and ensure continuous availability for their consumers, which strategy should they employ?

A. Create a new version of the Snowflake Native Application containing the updated data and deprecate the previous version. Consumers will need to migrate to the new version.
B. Use tasks and streams to incrementally refresh the data in the shared database. Implement error handling to manage potential data inconsistencies.
C. Completely replace the underlying shared database with a new version during off-peak hours.
D. Perform direct updates to the tables within the shared database. Use SALTER TABLE ... SWITCH WITH' to minimize locking during the update process, creating new tables with updated data.
E. Utilize Snowflake's cloning feature to create a duplicate of the shared database, update the data in the clone, and then swap the original and cloned databases using 'ALTER DATABASE SWAP WITH'.

Answer: B

Explanation:
Using tasks and streams allows for incremental data updates, minimizing downtime and providing continuous data availability. Error handling is crucial for maintaining data consistency. Swapping databases is not possible because native apps control the database, and consumers access it via a share. Simply updating the table will cause downtime for consumers.

NEW QUESTION # 255
You are developing a Snowflake Native Application that utilizes Snowpark Container Services (SPCS) for its backend processing. The application requires secure access to a specific endpoint hosted within the SPCS environment. You've defined a service in your SPCS compute pool. Which of the following SQL commands is the MOST secure and appropriate way to expose an endpoint for access from within the application's consumer environment, assuming the endpoint requires OAuth authentication?

A. ALTER SERVICE my_service ADD ENDPOINT my_endpoint WITH AUTHENTICATION TYPE = OAUTH;
B. CREATE SERVICE ENDPOINT my_endpoint FOR SERVICE my_service WITH AUTHENTICATION TYPE = SNOWFLAKE_JWT;
C. CREATE SERVICE ENDPOINT my_endpoint FOR SERVICE my_service WITH AUTHENTICATION TYPE = NONE;
D. BIND SERVICE ENDPOINT my_endpoint FOR SERVICE my_service WITH AUTHENTICATION TYPE = OAUTH TO APPLICATION PACKAGE;
E. CREATE SERVICE ENDPOINT my_endpoint FOR SERVICE my_service WITH AUTHENTICATION TYPE = OAUTH;

Answer: D

Explanation:
The 'BIND SERVICE ENDPOINT command is used specifically to expose a service endpoint for use within the application package. Importantly, it connects the endpoint to the APPLICATION PACKAGE making it accessible to consumers of the application. 'AUTHENTICATION TYPE = OAUTH' ensures that requests to the endpoint are authenticated using OAuth tokens, providing a secure mechanism for access. Creating an endpoint directly (CREATE SERVICE ENDPOINT) doesn't inherently link it to the application package, making it less controlled from a security perspective within the native app context. 'SNOWFLAKE_JWT while potentially valid, OAuth is generally better suited to external API authentication in this scenario. 'AUTHENTICATION TYPE = NONE is highly insecure and not recommended.
