You are preparing a Snowflake Native Application for its initial release. You have a 'setup.sqP file that creates necessary tables and roles. You are also planning for future updates. Which of the following practices will BEST ensure smooth, version-upgrade compatible deployments for your application's consumers?

• A. Always drop and recreate all application objects in each new version's 'setup.sqr to ensure a clean slate.
• B. Include detailed comments in 'setup.sql' explaining the purpose of each SQL statement and the logic behind schema changes.
• C. Avoid using 'CREATE OR REPLACE TABLE in 'setup.sqr and always use 'CREATE TABLE IF NOT EXISTS.
• D. Use a consistent naming convention for all application objects and clearly document any breaking changes in release notes.
• E. Use stored procedures within 'setup.sqr to encapsulate schema changes and data migrations, making them idempotent.

You are developing a Snowflake Native Application that processes financial transactions. You want to implement a robust version management strategy. You have created versions 'v1_0', 'V1 _ 1', and 'v2 Version has a critical bug fix and needs to be prioritized for immediate deployment to specific consumer accounts that reported issues, while contains significant feature enhancements and is undergoing phased rollout. What is the most efficient and secure way to manage these releases in Snowflake?

• A. Option B
• B. Option D
• C. Option C
• D. Option A
• E. Option E

A Native App provider has released a new version of their application. After installation, some consumers report encountering 'SQL compilation errors' when using certain features that rely on Java UDFs. The provider has thoroughly tested the application and cannot reproduce the error in their development environment. What are the MOST LIKELY causes of this issue and how can the provider systematically troubleshoot and resolve it? (Select TWO)

• A. The consumer's Snowflake account has insufficient compute resources to execute the Java UDFs. The provider should instruct the consumer to upgrade their virtual warehouse size.
• B. The Java UDFs are encountering data type mismatches due to differences in regional settings or data formats between the provider's and consumer's environments. The provider should enforce strict data validation and type conversion within the UDFs.
• C. The Java UDFs are using external libraries that are not compatible with the consumer's Snowflake environment or are missing entirely. The provider should explicitly declare all dependencies in the application manifest and ensure they are properly packaged and deployed.
• D. Consumer-side firewall rules are blocking access to external resources used by the Java UDF. The provider should thoroughly document the necessary network configurations for consumers.
• E. The provider's development environment is using a newer version of the Snowflake Java runtime than the consumer's environment. The provider should downgrade their development environment to match the oldest supported version and re-test the application.

A Snowflake Native App developer is designing the upgrade process for their application. They need to ensure that data stored in the application's managed tables is preserved during the upgrade and that the application remains functional throughout the upgrade process. Which of the following strategies should the developer implement to achieve these goals? (Select TWO)

• A. Implement a versioning system for the application's metadata using the ' APPLICATION VERSION' construct, ensuring that the new version can handle data from previous versions.
• B. Utilize Snowflake's data sharing capabilities to create a read-only replica of the application's data for the new version to access during the upgrade.
• C. Before upgrading, unload all data from the application's tables to cloud storage, and then reload the data into the new version after the upgrade is complete.
• D. Use the 'DROP TABLE command with the 'CASCADE' option to remove all tables and views before deploying the new version of the application.
• E. Design the application's data model to be backward-compatible, allowing the new version to read and write data in the format used by previous versions. Use 'ALTER TABLE to add new columns or modify existing ones without breaking existing functionality.

A Snowflake Native App provider wants to implement row-level security (RLS) in an event table to ensure that consumers only receive events pertaining to their specific organization, even if they have been granted USAGE on the event table function. How can this be achieved?

• A. Create a row access policy that filters rows in the event table based on the APP_INSTANCE_ID() function, ensuring each consumer only sees events related to their application instance.
• B. Row-level security cannot be enforced on event tables shared through Snowflake Native Apps due to security limitations.
• C. Create a masking policy that filters rows in the event table based on the CURRENT_ACCOUNT() function to match the consumer's account ID.
• D. Implement a custom stored procedure that acts as a proxy for accessing the event table, filtering data based on the consumer's user ID.
• E. Create a view on top of the event table that includes a WHERE clause filtering by APP INSTANCE ID() and grant access to the view instead of the base table.
