Snowflake SnowPro Specialty - Native Apps Sample Questions (Q140-Q145):

NEW QUESTION # 140
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. The correct approach is not listed, as consumers cannot directly query event tables associated with Snowflake Native Applications for security reasons.
B. 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.
C. Ensure that the consumer account has the 'MONITOR privilege on the application, as this is required to query event tables associated with native applications.
D. Verify that the application role defined in the application manifest has been granted the 'SELECT privilege on the event table within the provider account.
E. 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'.

Answer: E

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 # 141
You are developing a Snowflake Native Application that provides a data enrichment service. This service requires the consumer to grant the application access to a specific table in their account. You want to ensure that upgrades to your application do not inadvertently break existing consumer configurations. You decide to use a versioned schem a. Which of the following steps are essential during the setup script execution to achieve this and maintain backward compatibility during future upgrades?

A. Define a custom role within the application package and grant it the necessary privileges to read the consumer's table via a secure view. Then, grant the application role the USAGE privilege on this custom role. This ensures that the application role can assume the custom role's privileges for data access.
B. Create a new unversioned schema named 'APPLICATION' and install all application objects within it. This provides a consistent namespace for all consumers, regardless of the application version.
C. Grant the application role 'OWNERSHIP on the consumer's table directly. This allows the application full control and ensures consistent data access regardless of future schema changes within the application.
D. Create a versioned schema using 'CREATE SCHEMA VERSION = ' . Grant the application role 'USAGE on this versioned schema, and ensure all application logic references objects within this schema.
E. Create a secure view in the versioned schema that accesses the consumer's table. Grant the application role 'SELECT on this secure view. This provides a stable interface that isolates the application from direct changes to the consumer's table.

Answer: D,E

Explanation:
Options B and D are correct. Creating a versioned schema allows for managing changes in your application's data structures. By creating a secure view and granting the application role 'SELECT on it, you isolate your application from direct modifications to the consumer's table, ensuring backward compatibility. Option A is incorrect because an unversioned schema doesn't address the need for backward compatibility during upgrades. Option C is generally discouraged due to security concerns of granting ownership. Option E, while useful, is not the core reason to use a versioned schema to protect from consumer changes.

NEW QUESTION # 142
You are developing a Snowflake Native Application intended for the Snowflake Marketplace. Before listing your application, you want to ensure it adheres to Snowflake's best practices for security, performance, and usability. Which of the following steps should you take to validate your application prior to submission? (Choose three)

A. Submit your application code to a third-party security auditing firm for a comprehensive vulnerability assessment.
B. Deploy the application to a separate Snowflake account and simulate user interactions to validate the application's usability and functionality.
C. Use Snowflake's built-in code scanning tools (if available in the future) to automatically identify security vulnerabilities and code quality issues.
D. Manually review the application code to identify potential SQL injection vulnerabilities and optimize query performance.
E. Conduct thorough testing of the application on various Snowflake editions and sizes to ensure scalability and performance across different environments.

Answer: B,D,E

Explanation:
Manual code review for SQL injection and performance (A) is crucial, as no automated tool currently perfectly covers all scenarios. Thorough testing (C) is essential to ensure scalability. Simulating user interactions in a separate account (D) helps validate usability and functionality. Third-party audits (E) are good practice but not explicitly required for initial Marketplace submission. Code scanning tools mentioned in (B) are a hypothetical scenario, which are not currently readily available on Snowflake marketplace at the time this response was constructed.

NEW QUESTION # 143
You are developing a Snowflake Native Application that interacts with sensitive customer dat a. You want to implement robust security scanning before publishing to the Snowflake Marketplace. Which of the following strategies are MOST effective to detect and prevent potential vulnerabilities before submitting your application, considering limitations on marketplace pre-publication scanning capabilities?

A. Implement a comprehensive CI/CD pipeline that includes static code analysis (SAST) using tools like SonarQube or similar, focusing on SQL injection, cross-site scripting (XSS), and insecure deserialization vulnerabilities. Include unit and integration tests with parameterized inputs. Regularly update dependency versions and scan for known vulnerabilities in third-party libraries included in your application's code (e.g., Python libraries).
B. Rely solely on Snowflake's built-in scanning during the Marketplace submission process, as it covers all known vulnerabilities.
C. Manually review all code for potential security flaws and ensure adherence to secure coding practices.
D. Employ a third-party penetration testing service to perform a black-box test of the application after deployment in a staging environment but prior to Marketplace submission.
E. Only use Snowflake provided templates and example codes as these are already pre-approved from security perspectives

Answer: A,D

Explanation:
Option B and D provides a good answer as Snowflake's Marketplace scanning is limited, a multi-layered approach is crucial. SAST and dependency scanning within a CI/CD pipeline (B) allows for early detection of many common vulnerabilities. Penetration testing (D) provides an external, real-world assessment of the application's security posture. Relying solely on Snowflake's scanning (A) is insufficient. Manual code review (C), while helpful, is prone to human error. Only using Snowflake provided templates is very restrictive and not a solution.

NEW QUESTION # 144
You are developing a Snowflake Native Application and need to implement robust logging for troubleshooting purposes. You want to capture detailed information about function calls, including input parameters and return values. Which of the following approaches offers the MOST comprehensive and secure solution for logging within a Snowflake Native Application, considering the limitations imposed by the Snowflake environment?

A. Using 'SYSTEM$LOG' with debug level logging and capturing logs in a secure internal stage, managed by the provider, ensuring data privacy and limited consumer access.
B. Using ' SYSTEM$LOG' with trace level logging and store the logs into internal stage, accessible only by the application's service user.
C. Writing log messages to an external stage (e.g., AWS S3, Azure Blob Storage) that is accessible to both the provider and consumer accounts.
D. Leveraging Snowflake's event tables and configuring the application to emit custom events, then creating views on those event tables within the consumer's account.
E. Employing 'EXECUTE IMMEDIATE to write log messages directly to a dedicated logging table within the consumer's account.

Answer: A

Explanation:
Option E is the most secure and comprehensive. 'SYSTEM$LOG' allows for structured logging. An internal stage ensures that the consumer does not have direct access to sensitive log data. The provider maintains control, addressing security concerns. Options A and C are less secure, as they might expose sensitive application data. Option D is generally discouraged for sensitive information due to compliance concems, and Option B is problematic because 'EXECUTE IMMEDIATE' inside an application package will be blocked.
