Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. Consider a scenario where a Snowflake Native Application contains a task named "daily data sync'. This task needs to be executed in the consumer's account. To enable proper monitoring and governance within the consumer's account, the consumer wants to tag the executions of this task. Which of the following actions must the application provider take to ensure that the consumer can successfully tag the 'daily data sync' task executions without compromising the security of the application or requiring the consumer to have elevated privileges on the application database?

A) The provider must grant the APPLY TAG privilege on the account to the consumer s account role.
B) The provider must grant the OWNERSHIP privilege on the task to the consumer's account role, allowing the consumer to set tags directly.
C) The provider must grant the APPLY MASKING POLICY privilege on the task to the consumer's account role, enabling the consumer to configure tags via masking policies.
D) The provider cannot enable the consumer to tag the task executions without granting elevated privileges on the application database or compromising security; tagging is solely the provider's responsibility.
E) The provider must grant the APPLY TAG privilege on the task to the consumer's account role. No other configuration is necessary.

2. A Native Application is being developed that requires access to the consumer's Snowflake account for billing purposes. The application needs to record the query history of the consumer's account to estimate resource usage. Which is the MOST secure and efficient method for the Native App to access this data, minimizing the permissions granted to the app and considering the governance aspects?

A) Use the 'READ SESSION' privilege to allow the application to read the current session context and infer the resource usage from it.
B) Grant the ' USAGE privilege on the 'SNOWFLAKE' database to the Native App's service account, allowing it to query all tables and views in that database.
C) Grant the 'ACCOUNTADMIN' role to the Native App's service account. This provides full access to the account's query history.
D) Create a stored procedure within the Native App that executes as the 'OWNER and queries the view. The stored procedure is granted to the Native App's service account with 'EXECUTE privileges.
E) Grant the ' MONITOR USAGE' privilege to the Native App's service account, allowing it to query the view.

3. You are developing a Snowflake Native App that uses JavaScript stored procedures. During consumer testing, you observe inconsistent behavior: sometimes the app works perfectly, other times it throws intermittent 'JavaScript out of memory' errors. You suspect a memory leak in your JavaScript code. Which of the following actions could help you diagnose and resolve this issue effectively?

A) Enable detailed logging within your JavaScript stored procedures using 'CALL SYSTEM$LOG(...)'})$ and analyze the logs for excessively large data structures or recursive function calls.
B) Contact Snowflake support immediately, as 'JavaScript out of memory' errors always indicate a platform bug.
C) Increase the warehouse size for the consumer's instance where the app is installed, assuming larger warehouses always provide more memory for JavaScript execution.
D) Refactor your JavaScript code to minimize the creation of large, temporary objects and ensure that objects are properly garbage collected by setting unused object references to 'null'.
E) Use the 'INFORMATION SCHEMA.QUERY HISTORY view on the consumer account to examine the query profiles of the JavaScript stored procedures, looking for excessive memory consumption or spillover to local storage.

4. A Snowflake Native Application developer wants to ensure that a specific stored procedure, 'UPDATE CUSTOMER STATUS, within their application can only be executed by users who have been granted the 'CUSTOMER ADMIN' role in the consumer's account. How can the developer enforce this authorization check within the stored procedure's code?

A) Use the function within the stored procedure to verify that the 'CUSTOMER_ADMIN' role is currently active in the session. If not, raise an error.
B) Utilize the 'SESSION CONTEXT()' function to check for a specific context variable set only when a user with the 'CUSTOMER ADMIN' role is connected.
C) Implement a custom function that calls 'SYSTEM$GET PRIVILEGES()' and checks if the user executing the stored procedure possesses the 'CUSTOMER ADMIN' role.
D) Grant the 'EXECUTE privilege on the stored procedure only to the 'CUSTOMER_ADMIN' role in the consumer's account.
E) Use the 'CURRENT ROLE()' function within the stored procedure to check if the current role is 'CUSTOMER ADMIN'. If not, raise an error.

5. You are developing a Native App on Snowflake that collects usage data from consumer accounts. You need to store this data securely and efficiently, and you anticipate that the volume of data will grow rapidly. Which of the following strategies would you consider to OPTIMIZE storage and query performance for this usage data within the application?

A) Use clustering keys on columns commonly used in queries, such as timestamp and consumer account ID. Consider data compression options if available.
B) Create separate tables for each consumer account to store their usage data.
C) Partition the usage data table by consumer account ID to isolate data from different consumers.
D) Implement a data retention policy to automatically purge older usage data that is no longer needed.
E) Store all usage data in a single table and rely on Snowflake's automatic clustering to handle performance.
