You've installed a Snowflake Native Application in your consumer account. You are trying to establish observability and telemetry to monitor its performance and identify potential issues. However, you notice that you only have limited visibility into the application's internal operations. Which actions should you take to enhance observability, assuming the provider has implemented appropriate mechanisms?

• A. Examine the APPLICATION USAGE view in the SNOWFLAKE database to track resource consumption and query performance of the application's components.
• B. Request the application provider to grant you direct access to the application's internal logs and system tables.
• C. Subscribe to events shared by the application provider through Snowflake's event sharing mechanism, if the provider has enabled it. Leverage shared views exposing specific metrics.
• D. Use Snowflake's Query Profile to analyze the execution plans of queries initiated by the application.
• E. Enable detailed logging in your consumer account to capture all SQL statements executed by the application, then analyze these logs.

A Snowflake Native App installed in a consumer account needs to access data in a specific table within the consumer's account to perform its core functionality. Which of the following is the MOST secure and recommended way for the application to gain access to this data? (Assume the application developer does not have direct access to the consumer's Snowflake account.)

• A. The application prompts the consumer for their Snowflake account credentials and uses those credentials to access the data.
• B. The consumer shares the table directly with the application provider's Snowflake account.
• C. The consumer creates a secure view on top of the table and grants 'SELECT privilege on the secure view to the application's installed application object (application instance).
• D. The consumer grants the "GLOBAL' privilege 'SELECT on the table directly to the application package name.
• E. The application provider requests the 'IMPORTED PRIVILEGES on the consumer account, allowing the application to access any object within the account.

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. 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.
• B. 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.
• 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. 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.
• E. Use the 'DROP TABLE command with the 'CASCADE' option to remove all tables and views before deploying the new version of the application.

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. Completely replace the underlying shared database with a new version during off-peak hours.
• B. 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.
• C. Use tasks and streams to incrementally refresh the data in the shared database. Implement error handling to manage potential data inconsistencies.
• D. 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.
• 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'.

A consumer wants to install a Snowflake Native App. They have already identified the app in the Snowflake Marketplace. After attempting to install the application, they receive an error stating 'Insufficient privileges to install application'. Which of the following steps are MOST likely required to resolve this issue? (Select Two)

• A. The consumer needs to have the 'CREATE APPLICATION PACKAGE privilege on the target account.
• B. The consumer's account administrator needs to grant the 'APPLY APPLICATION' privilege to the role used by the consumer attempting to install the application.
• C. The application provider needs to explicitly share the application package with the specific role the consumer is using for installation.
• D. The consumer's account administrator needs to grant the 'CREATE APPLICATION' privilege to the role used by the consumer attempting to install the application.
• E. The application provider needs to grant the 'IMPORTED PRIVILEGES to the consumer account.
