Snowflake SnowPro Specialty - Native Apps Sample Questions (Q26-Q31):

NEW QUESTION # 26
A data engineer, Alice, is developing a Snowflake Native Application that exposes a stored procedure, 'calculate_aggregate' , within the application schema 'app_schema'. She initially granted privilege on the application database to the 'analyst_role' and EXECUTE privilege on 'calculate_aggregate' to the same role. Later, due to a security audit, she needs to revoke the 'EXECUTE privilege from 'analyst_role' but wants to ensure users assigned to 'analyst_role' can still access other objects in the application database (but not execute this specific stored procedure). Which of the following actions achieves this goal MOST efficiently and securely?

Answer: E

Explanation:
Option A is the most precise and efficient. It revokes only the 'EXECUTE privilege on the specific stored procedure 'calculate_aggregate' from the 'analyst_role' , leaving other privileges and access to other objects within the database intact. Option B would revoke all privileges, potentially more than intended. Options C and D are unnecessarily broad, affecting access to the entire database or schema, which is not the requirement. Option E addresses ownership, not execution privileges.

NEW QUESTION # 27
You are building a Snowflake Native App that aggregates data across multiple consumer accounts. Your app needs to securely access data in each consumer's Snowflake account without requiring them to share their credentials directly. You are evaluating different options for secure data access. Which of the following strategies are viable and recommended to implement this, maximizing security and minimizing administrative overhead for the consumer?

A. Implement a data sharing agreement where consumers create a share from their account and grant usage to your application's account using secure data sharing. The application account can then create a database from this share.
B. Utilize Snowflake's Native App data sharing capabilities where the provider app shares data products back to the consumer account and the consumer account can use this inside their apps.
C. Use Snowflake Data Clean Rooms to allow the app to query data from the consumers accounts.
D. Have consumers create and share a JWT (JSON Web Token) with your application. The JWT will be used to authenticate against their Snowflake instance via an external function.
E. Require consumers to grant SELECT privileges on their tables directly to the application's account. This necessitates the consumer to manage grants directly.

Answer: A,B

Explanation:
Granting SELECT directly (A) requires the consumer to manage grants directly, which is not ideal for scalability or security. Passing JWT tokens (D) is complex and requires careful management of keys. Snowflake Data Clean Rooms(B) are not the correct solution to get consumer data in Provider App.. Secure data sharing (C) is a viable and secure option, as it allows consumers to share data without exposing credentials. Snowflake's Native App sharing Data Products back to the consumer account (E) is the best option for secure data access.

NEW QUESTION # 28
You are developing a Snowflake Native Application that processes sensitive customer dat a. You need to ensure that the application logs all relevant events for auditing and debugging purposes, while adhering to data privacy regulations. Which of the following strategies would BEST facilitate secure and compliant logging within the application provider's environment?

A. Utilize Snowflake's Event Tables with appropriate masking policies to redact sensitive information before logging. Configure a data retention policy that complies with regulatory requirements. Define alerts based on specific event types to proactively address potential issues within the application.
B. Log all events directly to a Snowflake table within the application's container, granting direct access to the consumer account for auditing.
C. Send logs to an external logging service via API calls, ensuring the service is SOC 2 compliant and offers end-to-end encryption. Consumers configure the service to receive logs and set up audit trails.
D. Encrypt all sensitive data within the logs using a key managed by the consumer before writing to a standard Snowflake table within the application container. Provide the consumer with the decryption key upon request.
E. Implement logging using standard Python logging libraries within the application code and direct the logs to stdout/stderr. Rely on the consumer to configure logging infrastructure within their account to capture the output.

Answer: A

Explanation:
Option B is the best approach. Snowflake's Event Tables provide a secure and managed environment for logging within the provider's account. Masking policies ensure data privacy by redacting sensitive information before logging. Retention policies help comply with regulations. Alerting allows for proactive issue resolution. Options A, C, D, and E present security or compliance risks.

NEW QUESTION # 29
You are developing a Snowflake Native Application that performs complex data transformations. As part of your development lifecycle, you need to ensure that your code behaves idempotently even when facing intermittent network errors or unexpected disruptions. Consider the following function written in Snowpark Python that updates a table:

What modification is necessary to make this function idempotent against disruptions during the writing process to Snowflake and unexpected execution?

A. Use a 'MERGE statement to selectively update only changed rows, while ignoring existing ones.
B.
C. Create a temporary table, write the transformed data to the temporary table, and then atomically rename the temporary table to the original table name.
D. Wrap the 'df.write' operation in a retry mechanism with exponential backoff to handle intermittent network errors.
E. Leverage Snowflake's 'TRANSACTIONAL_REPLICATION' to replicate the operations to minimize data loss in between failures.

Answer: C

Explanation:
Option C provides the best approach to guarantee idempotency. Creating a temporary table, writing the data to it, and then atomically renaming it ensures that the table is either fully updated or remains in its original state. If failures happen after the creation of temporary table and before it is renamed (a failure which is assumed to be very rare), then, after code recovery and execution, the table would be first created and then atomically renamed, thus achieving idempotency. Retrying writes (B) can help with network errors but doesn't inherently guarantee idempotency if the write partially succeeds before the error. 'append' (A) leads to duplicate data in the event of re-execution. 'MERGE (D) might lead to data inconsistency depending on the transformation logic. 'TRANSACTIONAL REPLICATION' (E) is a good approach for disaster recovery but will not help to resume the execution, after recovering the code after failure, at the point where it failed before.

NEW QUESTION # 30
You are building a Snowflake Native Application that includes a stored procedure to perform data transformation. This stored procedure needs to access external data sources using a secure API. Which of the following methods provides the MOST secure and recommended approach for managing API credentials within the Snowflake Native Application context?

A. Use the consumer's account's environment variables to store API credentials. The application retrieves credentials from there.
B. Hardcode the API credentials directly within the stored procedure code. This is the simplest approach for development and testing.
C. Store the API credentials directly within the stored procedure code as encrypted strings. Decrypt them at runtime using a key stored in a separate table.
D. Store the API credentials in a configuration file included within the application package. Read the credentials from this file within the stored procedure.
E. Use Snowflake's Secret object to securely store the API credentials. Access the Secret within the stored procedure using function.

Answer: E

Explanation:
Option C provides the most secure and recommended approach. Snowflake's Secret object is specifically designed for securely storing and managing sensitive information like API credentials. The 'SYSTEM$GET_SECRET function allows controlled access to these secrets within the stored procedure. Option A introduces unnecessary complexity and potential vulnerabilities with custom encryption. Option B exposes the credentials within the application package, making it less secure. Option D is not feasible and secure, because consumer managed secrets is not a built in functionality for Native apps . Option E is extremely insecure and should never be used.
