Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. Consider the following scenario: You're developing a Snowflake Native Application that requires both data loading and complex analytical queries. You plan to use separate warehouses to optimize performance and manage resources effectively. Given the requirements, which of the following warehouse configurations is the MOST appropriate?

A) Two warehouses: one dedicated to data loading configured with "WAREHOUSE_SIZE = X-SMALL' and another for analytical queries configured with 'WAREHOUSE SIZE = LARGE and 'MAX CONCURRENCY LEVEL = 8'.
B) One warehouse sized 'X-SMALL' for data loading and another sized URGE' for analytical queries.
C) Two warehouses: one with 'AUTO SUSPEND = 60' for data loading and another with 'AUTO SUSPEND = 3600' for analytical queries.
D) Two warehouses: one dedicated to data loading, configured with to save costs and other warehouse for analytical queries.
E) One large warehouse to handle both data loading and analytical queries, sharing resources to minimize costs.

2. Your Snowflake Native App's setup script needs to create a new schema and grant specific privileges to a custom role defined within the application. However, the setup script is failing with an error related to insufficient privileges. You've verified that the application role has the OWNERSHIP privilege on the application package. What is the MOST likely cause of this issue and how can it be resolved?

A) The application role needs the USAGE privilege on the database. Grant USAGE on the database to the application role using 'GRANT USAGE ON DATABASE TO APPLICATION ROLE
B) The application role lacks the CREATE SCHEMA privilege on the database. Grant the CREATE SCHEMA privilege on the database to the application role using 'GRANT CREATE SCHEMA ON DATABASE TO APPLICATION ROLE
C) The setup script is attempting to create a schema with the same name as an existing schema in the consumer account. Ensure the schema name is unique within the consumer account.
D) Setup scripts cannot create schemas, as schemas are automatically provisioned. Only tables, views and other objects can be created by the script.
E) The setup script must explicitly activate the application role before creating the schema. Add the following line to the setup script: 'USE ROLE

3. You are tasked with deploying a Snowflake Native Application that performs real-time data analysis. The application requires a warehouse to run and a user with specific privileges to access dat a. You want to automate the deployment process as much as possible, including warehouse creation, user provisioning, and privilege granting, all within the application package. Given the security considerations and best practices for Snowflake Native Applications, which of the following approaches is the MOST secure and recommended?

A) Use a setup script within the application package, granting it the 'APPLY APPLICATION PASSTHROUGH PRIVILEGES privilege. This will enable the application to inherit the privileges of the user who installed the application, allowing it to create the warehouse and user on their behalf.
B) Request the consumer to manually create the warehouse and user with the required privileges before installing the application. Provide detailed instructions in the application documentation.
C) Include a SQL script within the application package that uses the 'CREATE WAREHOUSE, 'CREATE USER , and 'GRANT commands to create the warehouse, user, and grant necessary privileges. The script will be executed by the consumer upon installation.
D) Utilize the 'INSTALL' privilege when creating the application package and execute the SQL script (containing 'CREATE WAREHOUSE, 'CREATE USER , and 'GRANT) within the application's setup script using the 'EXECUTE IMMEDIATE command. This allows the application to create resources within the consumer's account.
E) Employ a secure deployment pipeline that leverages a separate, pre-authorized Snowflake account to provision the warehouse and useL The application package then only includes the application logic, assuming the resources already exist.

4. A company publishes a Snowflake Native Application on the Snowflake Marketplace providing aggregated sales dat a. They want to ensure data is fresh and updated daily at 00:00 UTC. They are considering several approaches to automate this data refresh process.
Which of the following methods are MOST effective and SECURE for scheduling and executing this daily data update within the Snowflake Native Application environment? Choose two.

A) Schedule a Python script using an external task service (e.g., AWS Lambda) that connects to Snowflake and executes the data refresh procedure.
B) Leverage Snowflake's Data Marketplace update scheduling feature (if available and applicable to their type of listing) to automatically refresh the data.
C) Utilize a cron job on a virtual machine to execute a SQL script via SnowSQL, connecting to Snowflake and refreshing the data.
D) Use Snowflake Tasks scheduled to run daily at 00:00 UTC to execute a stored procedure within the Native Application that updates the data.
E) Implement a Java-based scheduler within the Snowflake Native Application itself using UDFs, triggered by an external service via API integration.

5. You are designing the setup script for a Snowflake Native Application. This application requires the creation of several views based on data residing in the consumer's account. These views need to be dynamically created based on a configuration table that is part of your application package. The configuration table contains view names, the underlying tables in the consumer's account, and the specific SQL queries for each view. The design must adhere to best practices for security and data governance. Which approach would you use for designing this setup script, considering security vulnerabilities and execution context?

A) Create a series of static 'CREATE VIEW' statements within the setup script, each targeting a predefined table in the consumer's account. The application will handle data filtering within these views.
B) Use a stored procedure, owned by the application, to dynamically generate and execute the 'CREATE VIEW statements. The stored procedure reads the view definitions from the configuration table and creates the views using dynamic SQL.
C) Use dynamic SQL generation with proper escaping functions (e.g., to prevent SQL injection. Store the generated SQL in a temporary table, and then execute each statement from the temporary table using 'EXECUTE IMMEDIATE
D) Directly construct and execute the 'CREATE VIEW' statements within the setup script using string concatenation, reading the view definitions from the configuration table. This minimizes code complexity and ensures immediate view creation.
E) Employ parameterized SQL (using '?' 7 placeholders) within the 'CREATE VIEW' statements, binding the view names and queries read from the configuration table. Execute these statements using 'EXECUTE IMMEDIATE to prevent SQL injection vulnerabilities.
