Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application that needs to securely access data in a consumer's account. The application requires the consumer to grant specific privileges to a custom role created and managed within the application package. Which of the following steps are absolutely essential for correctly configuring the application package to ensure this secure data access, and how should the setup script handle the privilege granting?

A) Create a share from the provider account to the consumer account, granting the consumer read access to the application package's data. Then, use a setup script to grant ownership of the data to the application role after installation.
B) Utilize a service account to access the data, providing the service account's credentials as part of the application setup. The application will then use the service account to access the consumer's data.
C) Grant the 'USAGE privilege on the consumer's database and schema to the application's role within the setup script. This implicitly allows the application to read all data within that schema.
D) The consumer must manually grant the necessary privileges to the application's role after the application is installed, as the application package cannot automatically modify the consumer's security settings.
E) Define the required privileges in the application package manifest (snowflake.yml). Ensure that the setup script includes commands to grant the specific privileges on the consumer's data to the application's custom role, using 'GRANT ON TO ROLE within an EXECUTE IMMEDIATE statement in the setup script. The setup script should also define the application role.

2. Consider a scenario where you are developing a Snowflake Native App which utilizes a UDF (User-Defined Function). This UDF needs to access a secure external API using a secret stored securely within Snowflake. Which of the following statements are accurate regarding the necessary privileges and architecture for this setup? (Select all that apply)

A) The application developer needs the 'CREATE SECRET privilege to create the secret in the application package.
B) The application package needs the EXECUTE privilege on the secret for the UDF to use it.
C) The application developer needs the "APPLY privilege to create the secret in the application package.
D) The application instance must be granted the REFERENCE USAGE privilege on the secret to allow the UDF to access it.
E) The consumer account automatically inherits access to secrets created in the application package.

3. You are developing a Snowflake Native Application that relies on external functions (UDFs) hosted outside of Snowflake. You need to ensure that these external functions are securely accessed and that you can track their usage. Which of the following steps are required to correctly configure and manage access to external functions in your application package?

A) Define the external functions in the application manifest, specifying the API integration object used for secure communication and authentication.
B) No explicit configuration is required within the application package; external functions are automatically accessible once defined in the developer's Snowflake account.
C) Implement robust error handling and logging within the application code to capture any issues related to external function calls, including authentication errors, network connectivity problems, and data transformation failures.
D) Grant the 'USAGE privilege on the API integration object to the application role that will be calling the external functions within the application package. This is done through the application setup script.
E) Create a network rule in the application package that whitelists the IP addresses or hostnames of the external function endpoints. Ensure that the application manifest includes the property set to 'true' and references the network rule.

4. An organization is building a Snowflake Native App that performs complex data transformations. The transformation logic is encapsulated in a stored procedure. They want to allow consumer accounts to execute this stored procedure, but ONLY with the privileges of the application itself, preventing access to the consumer's data through the procedure. Which set of actions are required to achieve this?

A) Create the stored procedure with the ' EXECUTE AS OWNER clause and grant the ' EXECUTE APPLICATION' privilege on the application instance to the consumer's role.
B) Create the stored procedure with the 'EXECUTE AS OWNER clause and grant the 'USAGE privilege on the application package to the consumer's role.
C) Create the stored procedure with the ' EXECUTE AS CALLER clause and grant the 'EXECUTE APPLICATION' privilege on the application instance to the consumer's role.
D) Create the stored procedure with the ' EXECUTE AS OWNER' clause and grant the ' IMPORTED PRIVILEGES' on the application package to the consumer's role.
E) Create the stored procedure with the 'EXECUTE AS CALLER clause and grant the 'APPLY APPLICATION' privilege on the application package to the consumer's role.

5. 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) 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'.
B) 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.
C) Use tasks and streams to incrementally refresh the data in the shared database. Implement error handling to manage potential data inconsistencies.
D) Completely replace the underlying shared database with a new version during off-peak hours.
E) 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.
