Snowflake SnowPro Specialty - Native Apps Sample Questions (Q22-Q27):

NEW QUESTION # 22
Your Snowflake Native Application persists data within its managed container. You need to implement a robust review process for logging to ensure compliance and prevent the exposure of sensitive information. Which of the following steps should be included in your review process? (Select all that apply)

A. Automated scanning of log messages for Personally Identifiable Information (PII) using regular expressions or pattern matching, and automatic redaction or masking of detected PII.
B. Implementation of role-based access control (RBAC) to restrict access to log data based on job function and the principle of least privilege.
C. Granting all application developers full access to all log data to facilitate debugging and troubleshooting.
D. Disabling logging in production environments to minimize the risk of data exposure.
E. Periodic manual reviews of a sample of log messages by a designated security officer to ensure compliance with data privacy policies and identify any potential logging gaps or issues.

Answer: A,B,E

Explanation:
Options A, B, and D are essential for a robust logging review process. Automated scanning and redaction (A) help prevent PII exposure. Manual reviews (B) provide a human element to catch what automated systems might miss and ensure policies are followed. RBAC (D) restricts access to only those who need it. Option C is a security risk, and Option E hinders debugging and troubleshooting.

NEW QUESTION # 23
You are designing a Snowflake Native App that needs to store temporary state information specific to each consumer account. This state information should not be directly accessible to the consumer but must be persistent across application sessions. Which of the following approaches are valid and recommended for storing this data?

A. Store the state information in a private schema within the application package, ensuring that consumers do not have direct access.
B. Create a public schema in the application package and store the state information in tables within that schema. Grant SELECT access to the consumer's account on these tables.
C. Use external stages connected to a provider controlled AWS S3 bucket or similar.
D. Create secured views that expose the state data but control access through application roles.
E. Utilize internal stages within the application package to store the state data as files.

Answer: A,E

Explanation:
Options B and D are the correct approaches. Option D: Private schema, Consumers should not have direct access to the app's internal data. Storing state information in a private schema within the application package ensures that consumers cannot directly query or modify this data, preserving the application's internal state and security. Option B: Internal Stages, offer a way to store file-based data that is tightly coupled with the application package. It enables you to persist the state information for each consumer securely. Option A is incorrect as it gives consumers direct access. Option C is incorrect because the requirement says the data cannot be accessible, not that it should be controlled. Option E creates dependency on external infrastructure.

NEW QUESTION # 24
You are developing a Snowflake Native App that processes sensitive customer dat a. Your app needs to access data from a table owned by the consumer and write transformed data back to another table also owned by the consumer. To ensure data privacy and security, you decide to use a secure view for accessing the customer data and a stored procedure for writing the transformed data.
However, you are facing issues with privilege escalation when the stored procedure tries to access the secure view. The stored procedure is defined with the 'EXECUTE AS CALLER clause. Which of the following steps can you take to mitigate this privilege escalation issue and ensure secure data access?

A. Change the stored procedure to run with the 'EXECUTE AS OWNER clause. Ensure the consumer grants 'IMPORTED PRIVILEGES' on their database to your application. Create a database role owned by the application and grant USAGE on database to it and SELECT on secure view to the database role.
B. Change the stored procedure to run with the 'EXECUTE AS OWNER clause. Ensure the consumer grants 'IMPORTED PRIVILEGES' on their database to your application. Create a database role owned by the application and grant USAGE on database to it and SELECT on secure view to the database role. Also, grant the consumer database ownership to the application.
C. Revoke the 'SELECT privilege on the secure view from the application role. Grant the 'SELECT' privilege on the secure view directly to the stored procedure using the 'GRANT ... TO PROCEDURE syntax.
D. Grant the 'APPLY MASKING POLICY privilege on the customer data table to the application role. Define masking policies on the sensitive columns of the customer data table.
E. Grant the 'EXECUTE MANAGED TASK' privilege to the application role. Change the stored procedure to run with the 'EXECUTE AS OWNER clause. Ensure consumer grants 'IMPORTED PRIVILEGES' on their database to your application.

Answer: A

Explanation:
When using ' EXECUTE AS CALLER , the stored procedure executes with the privileges of the user calling it, which can lead to privilege escalation. To avoid this, switch to 'EXECUTE AS OWNER , which runs the procedure with the privileges of the procedure's owner (the application). Consumers granting 'IMPORTED PRIVILEGES' allows the application to access database objects. A database role owned by the application ensures consistent privileges, and granting USAGE on the database and SELECT on the secure view to this role provides the necessary access. The app should not get OWNERSHIP of the CONSUMER Database.

NEW QUESTION # 25
Consider the following scenario: You're developing a Snowflake Native Application that uses external functions to call an API endpoint. The API endpoint experiences intermittent outages. You need to implement a robust mechanism to handle these outages gracefully and log the errors appropriately. Which of the following approaches are BEST suited to achieve this within the constraints of a Snowflake Native Application?

A. Use snowflake pipes to write to a logging table in provider account.
B. Implement error handling within the external function's code (e.g., using try-except blocks in Python). Log any errors directly to the consumer's system event logs using ' SYSTEM$LOG'.
C. Implement a retry mechanism within the external function, using exponential backoff. Log errors and retry attempts to a dedicated logging table within the provider account using a secure UDF.
D. Utilize a queueing system (e.g., Kafka, SQS) to buffer requests to the external function. Implement error handling and retry logic within the queue consumer. Log failures to Snowflake Event Tables.
E. Rely solely on Snowflake's built-in monitoring tools to detect and report external function failures.

Answer: C,D

Explanation:
Options B and D are the best choices: B: Implementing a retry mechanism with exponential backoff within the external function allows the application to automatically recover from transient errors. Logging errors and retries to a secure UDF provides valuable insights into the frequency and nature of the outages. The logging table being in the provider account ensures control and security. D: A queueing system adds resilience by buffering requests. This allows the application to continue processing even if the external function is temporarily unavailable. Logging failures to Snowflake Event Tables provides a centralized, secure, and auditable record of the outages. Option A is incorrect because writing to the consumer's event logs directly isn't possible. Option C is insufficient because it lacks proactive error handling and detailed logging. Option E, while a way to ingest data, doesn't address the retry mechanism or provide context for failure analysis within the external function call.

NEW QUESTION # 26
A data provider wants to distribute a Snowflake Native Application that includes a secure view 'PROVIDER DB.PUBLIC.SALES SUMMARY' which aggregates sales dat a. They want to allow consumers of the application to query this view, but prevent them from accessing the underlying base tables. Which minimum set of privileges must be granted on the 'SALES SUMMARY view to enable this, assuming the application role is 'APP ROLE and the installing account doesn't want to use 'imported privileges' ?

A. GRANT ALL PRIVILEGES ON VIEW PROVIDER DB.PUBLISALES SUMMARY TO ROLE APP ROLE;
B. GRANT USAGE ON DATABASE PROVIDER DB TO ROLE APP ROLE; GRANT USAGE ON SCHEMA PROVIDER DPUBLIC TO ROLE APP ROLE; GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;
C. GRANT REFERENCES ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;
D. GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO SHARE WITH APP ROLE;
E. GRANT SELECT ON VIEW PROVIDER DB.PUBLIC.SALES SUMMARY TO ROLE APP ROLE;

Answer: B

Explanation:
The consumer needs 'USAGE' privilege on the database and schema containing the view to access it. The 'SELECT' privilege on the view itself is required to query it. 'GRANT ALL PRIVILEGES' is excessive. 'GRANT ... TO SHARE is not a valid syntax. REFERENCES is for foreign keys.
