Snowflake SnowPro Specialty - Native Apps Sample Questions (Q317-Q322):

NEW QUESTION # 317
You are developing a Snowflake Native Application that leverages Snowflake Event Tables to log application events. You notice that while the application is successfully writing events to the event table, consumers are reporting that they cannot query the event table. Assume that you have successfully implemented the logging mechanism in your code and data is being logged. Consider the following manifest section:

Which of the following steps is MOST critical to resolve this issue and ensure consumers can query the event table?

A. Verify that the application role defined in the application manifest has been granted the 'SELECT privilege on the event table within the provider account.
B. The correct approach is not listed, as consumers cannot directly query event tables associated with Snowflake Native Applications for security reasons.
C. Confirm that the event table is explicitly listed in the 'shared_objects' section of the application manifest with the correct 'object_name', 'source_type' set to event_table', and 'privileges' including 'SELECT'.
D. Ensure that the consumer account has the 'MONITOR privilege on the application, as this is required to query event tables associated with native applications.
E. Grant the 'APPLY MASKING POLICY privilege to the application role on the event table to enable consumers to see masked data, and the REFERENCE_USAGE privilege on the database and schema that contains the event table.

Answer: C

Explanation:
The most critical step is to ensure that the event table is correctly configured in the application manifest under the 'shared_objectS section, with the 'source_type' defined as 'event_table' and the 'privileges' including ' SELECT. This explicitly tells Snowflake that the event table is intended to be shared with consumers and that they should have the 'SELECT privilege on it. Without this, consumers will not be able to query the event table, regardless of other privileges. Other options are either not relevant or do not address the root cause of the problem. Option A, option B and option D are all wrong, as they are not related to the root cause of the problem. Option E, is correct as it ensures masking policy is not a problem. The privileges are not relevant in this case.

NEW QUESTION # 318
A team developing a Snowflake Native Application is encountering performance issues. They suspect that the warehouse configuration might be suboptimal. They want to dynamically adjust the warehouse size based on the CPU utilization. Which of the following approaches can effectively address these performance concerns and allow dynamic warehouse resizing while adhering to security best practices?

A. Develop a Snowflake Script owned by a dedicated application role. The script queries the view to determine average CPU utilization and dynamically resizes the warehouse using SALTER WAREHOUSE based on predefined thresholds. Grant the 'MODIFY privilege on the warehouse to the application role.
B. Develop a Snowflake script that queries the view, calculates the average CPU utilization over a period, and then executes 'ALTER WAREHOUSE' statement through the 'SYSTEM$WAIT' function to prevent resource contention. Assign the script's ownership to a dedicated application role.
C. Use an external task scheduling system (e.g., Airflow) to query the 'SNOWFLAKE.ACCOUNT USAGE.WAREHOUSE LOAD HISTORY view, calculate the average CPU utilization, and then execute ' ALTER WAREHOUSE using a Snowflake connector with credentials for a user with the ACCOUNTADMIN role.
D. Directly use Snowflake's in-built auto-scaling features to dynamically resize based on load, if available, with appropriate resource monitors setup to control costs. Also, develop a Snowflake Script owned by a dedicated application role, that queries the view to determine average CPU utilization and dynamically resizes the warehouse using 'ALTER WAREHOUSE based on predefined thresholds. Grant the 'MODIFY privilege on the warehouse to the application role.
E. Manually monitor warehouse CPU utilization and execute 'ALTER WAREHOUSE statements to resize the warehouse based on observed metrics. Use a dedicated Snowflake user for this purpose with the ACCOUNTADMIN role.

Answer: A,D

Explanation:
Option D offers a secure and automated approach. A Snowflake Script owned by an application role can safely query performance data and resize the warehouse. Granting 'MODIFY privilege is the correct way to allow an application role to alter the warehouse. Option A is manual and uses the powerful ACCOUNTADMIN role, which is not a best practice. Option B uses 'SYSTEM$WAIT which is not related to warehouse resizing and might be a anti-pattern and bad design. Option C uses an external system with the ACCOUNTADMIN role, which is less secure and complex. Option E utilizes both Snowflake's native auto-scaling and a custom script for a robust solution. It uses resource monitors which helps control costs and limits warehouse usages. This adds extra layer of protection and optimal utilization of resources, and is thus most correct and complete response.

NEW QUESTION # 319
A consumer reports that your Snowflake Native Application is consistently failing with an 'Insufficient privileges' error when attempting to execute a specific function. As the provider, you need to diagnose the issue. Which of the following steps should you perform FIRST, considering the principles of least privilege and secure data access in Snowflake Native Apps?

A. Grant the "APPLY MASKING POLICY privilege on the database to the application invoker role.
B. Request the consumer to grant 'OWNERSHIP of the target database to your application's service user.
C. Examine the function's definition and the objects it accesses to ensure that the necessary privileges are granted to the application's invoker's rights (IR) role or owner's rights (OR) role, and that a data access framework is in place when needed.
D. Grant the 'USAGE privilege on the entire application package to the consumer's account, ensuring they have access to all components.
E. Temporarily disable all security policies (e.g., row access policies, masking policies) in the consumer's account to isolate the problem.

Answer: C

Explanation:
The correct approach is to examine the function's permissions and the underlying objects (Option B). It is crucial to identify the specific privileges required by the function and grant them to the appropriate role (IR/OR). This approach adheres to the principle of least privilege. Granting broad privileges like in Options A, C, and E is a security risk. Disabling security policies (Option D) is a debugging tactic but should not be a long-term solution and could expose sensitive data.

NEW QUESTION # 320
You are publishing a Snowflake Native Application to the Marketplace. You've completed initial testing, and the application appears to function as expected. However, the security scan consistently fails with a 'Data Exfiltration' error. The application includes a stored procedure that aggregates data from several tables within the application container and writes the results to an external stage using the 'COPY INTO' command. Review the following code snippet:

Which of the following changes is MOST likely to resolve the 'Data Exfiltration' error during the security scan?

A. Implement row-level security policies on the 'aggregated_data' table to restrict access to sensitive rows.
B. Modify the stored procedure to only export data to a table within the application container instead of an external stage.
C. Remove the 'GRANT EXECUTE privilege on the 'export_data' procedure from the 'app_public' role.
D. Require the consumer to explicitly grant the application usage privilege on a secure external stage controlled by the consumer, and modify the procedure to validate the stage's existence and permissions before exporting data.
E. Encrypt the data written to the external stage using client-side encryption with a key managed by the application provider.

Answer: D

Explanation:
The 'Data Exfiltration' error indicates a potential risk of unauthorized data leaving the consumer's Snowflake environment. The root cause is often that the application provider has unrestricted control over where the data is exported. The solution is to require the consumer to control the external stage and explicitly grant the application usage privilege on it. This ensures that the consumer is aware of and approves the data export. Option A would break the functionality. Option B addresses data access within the container but doesn't prevent exfiltration if the application can still write to an uncontrolled stage. Option D adds complexity but doesn't fundamentally address the control issue. Option E restricts functionality unnecessarily.

NEW QUESTION # 321
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 CALLER 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 ' EXECUTE APPLICATION' privilege on the application instance to the consumer's role.
C. Create the stored procedure with the 'EXECUTE AS OWNER clause and grant the 'USAGE privilege on the application package 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.

Answer: B

Explanation:
The correct answer is C. Using 'EXECUTE AS OWNER ensures the stored procedure runs with the privileges of the application owner, isolating it from the consumer's privileges. Granting ' EXECUTE APPLICATION' allows the consumer's role to execute the application and its associated procedures within the security context of the application . 'EXECUTE AS CALLER would cause the procedure to run with the privileges of the consumer, defeating the isolation goal. 'USAGE, 'APPLY APPLICATION' and 'IMPORTED PRIVILEGES do not allow executing application.
