Snowflake SnowPro Specialty - Native Apps Sample Questions:
You are developing a Snowflake Native App that needs to be deployed across multiple regions. Your application relies on data stored in internal stages. Considering the limitations of Snowflake Native App Framework regarding regional availability and data residency, which of the following strategies is the MOST appropriate to ensure data availability and minimize latency for users in different regions?
- A. Package all necessary data within the application itself, eliminating the need for external data sources.
- B. Configure the application to access data in a central, globally accessible stage, regardless of the user's region.
- C. Design the application to use external stages (e.g., AWS S3, Azure Blob Storage) in each region and implement logic to access the nearest stage based on the user's location.
- D. Utilize Snowflake's data replication feature to replicate the internal stages and associated data to regional Snowflake accounts.
- E. Replicate the entire Snowflake account across all regions where the app is deployed.

A customer is attempting to install your Snowflake Native Application from the Snowflake Marketplace, but the installation fails. You need to troubleshoot the issue. Which of the following steps would provide the most direct and relevant information for diagnosing the cause of the installation failure?
- A. Examine the application's code repository for any recent changes that might have introduced errors.
- B. Query the view in the consumers account to retrieve detailed information about the installation attempt, including error messages and status codes.
- C. Ask the customer to share their Snowflake account identifier to check internal logs.

You are managing versions of a Snowflake Native App that persists data to tables within the consumer's account. You want to provide consumers with the ability to rollback to a previous version of the application without losing dat a. Which combination of Snowflake features and practices would best support this requirement?
- A. Implement a backup and restore mechanism within your application, creating regular snapshots of the consumer's tables and storing them in a secured location. Provide a rollback procedure that restores data from the appropriate snapshot.
- B. Require consumers to manually back up their data before each application upgrade and provide instructions on how to restore it.
- C. Combine Snowflake's Time Travel feature with automated scripts within your application that identify and restore tables affected by the rollback to the specific point in time when the previous version was active. Provide users with a simplified rollback process.
- D. Rely solely on Snowflake's Time Travel feature on the consumer's tables, instructing users to manually restore data to the desired point in time after rolling back the application.
- E. Store data version history within the application and reconstruct historical states on demand. This requires complex data modeling and coding.

You are developing a Snowflake Native Application with a custom setup script. Within the setup script, you need to perform different actions based on whether the application is being installed for the first time in a consumer's account, or if it's an upgrade from a previous version. Which of the following functions or techniques can you reliably use within the setup script to determine if the current execution is a fresh installation vs. an upgrade? (Assume the app version is maintained and accessible as a variable 'current_version' .)
- A. Use the table 'APPLICATION_REGISTRY' function to check for an existing entry for the application in the current account.
- B. Check if the current version is '1.0', assuming the initial version of the application will always be '1.0'.
- C. Use 'SYSTEM$GET_PREVIOUS_VERSION()' function inside the setup script. If it returns NULL, it is the first install.
- D. Query the 'INFORMATION_SCHEMAPPLICATIONS' view to check if the application name already exists in the consumer's account.
- E. Attempt to read a known persistent setting from the application's metadata. If the setting exists, it's an upgrade; otherwise, it's a fresh install. (Requires metadata setup in a previous version)
