Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application that relies on external functions (UDFs/UDTFs) for data processing. A new version of your application includes significant changes to these external functions, potentially affecting existing consumer data and queries. How should you manage the upgrade process to minimize disruption and ensure data integrity in consumer accounts? Assume consumers rely on your function names in their queries. Which of the following approach is MOST suitable?

A) Create new versions of the external functions with different names while maintaining the old functions in the new version. Consumers can then migrate to the new functions at their own pace. Use release directives to route new users to new functions.
B) Develop wrapper functions in the new version that call the original external functions with the new logic applied. Consumers can then gradually migrate to the wrapper functions without immediately changing their queries.
C) Update the external functions in place with the new logic. Snowflake's versioning will automatically handle any compatibility issues for existing queries.
D) Rename all the external functions in the new version and instruct consumers to update their queries accordingly after the upgrade.
E) Use release directives to direct users to an intermediate version that provides a compatibility layer for the external function changes. This layer translates calls to the old function names into calls to the new functions, allowing for a phased transition.

2. A software vendor is developing a Snowflake Native Application for fraud detection. They plan to distribute it via the Snowflake Marketplace. They have implemented robust data governance policies within their application. What steps must they take to ensure that these policies are enforced and clearly communicated to consumers using the application in their own Snowflake accounts, specifically related to data masking policies?

A) The vendor must create all masking policies using the WITH MASKING POLICY clause to ensure policies are enforced on the consumer side.
B) The vendor should create masking policies. Policies created with the 'OWNERSHIP clause will be granted to the application database role. If the application creates and then shares tables, the table owner (database role) will have the ability to grant 'APPLY MASKING POLICY on those objects.
C) The vendor should create a separate documentation detailing the data governance policies and provide it alongside the Snowflake Marketplace listing. Consumers are responsible for implementing these policies in their accounts.
D) Data governance policies should be implemented within the application's UI and enforced programmatically through stored procedures.
E) Data governance policies are automatically inherited by consumer accounts when they install the application.

3. 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) 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.
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) 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.

4. A Snowflake Native Application is designed to process customer data using a series of stored procedures. One of the stored procedures, process data', requires access to a stage named 'customer stage' in the consumer's account to load dat a. The application role 'app_role' is intended to manage all access within the application. However, the procedure fails with a permission error during testing in the consumer environment. Which of the following combination of steps is required to fix the problem?

A) Grant 'USAGE privilege on the database and schema containing 'customer_stage' to the provider account, and grant privilege on 'customer_stage' to the 'app_role' .
B) Grant 'USAGE privilege on the database and schema containing 'customer_stage' to the 'app_role', and grant 'READ privilege on 'customer_stage' to the app_role' .
C) The stored procedure needs to be defined with 'EXECUTE AS CALLER rights to assume the privileges of the role executing the procedure.
D) Grant 'USAGE privilege on the database and schema containing 'customer_stage' to the 'app_role', and create a new role in the consumer account, grant 'READ on the 'customer_stage' to this new role, then grant this new role to 'app_role' .
E) Grant 'READ and ' WRITE privilege on 'customer_stage' directly to the provider account.

5. You are designing a setup script for a Snowflake Native Application. This script needs to perform the following actions: 1. Create a secure view that exposes a subset of data from a table owned by the provider account. 2. Grant 'SELECT privilege on this secure view to a specific role within the consumer account, but ONLY if that role already exists in the consumer account. 3. Create a UDF in the provider account which calls external function. This UDF needs access to a secret stored in a Snowflake secret object. Which of the following code snippets BEST implements these requirements, ensuring both security and proper privilege management?

A)

B)

C)

D)

E)
