Snowflake SnowPro Specialty - Native Apps Sample Questions (Q153-Q158):

NEW QUESTION # 153
You are developing a Snowflake Native Application that requires specific roles to be assigned to consumers upon installation. Your setup script needs to automatically create these roles if they don't exist and grant appropriate privileges on application objects. Which of the following approaches is the MOST secure and efficient way to achieve this, assuming you want to minimize the attack surface?

A. Hardcode the role names in the setup script and create them using a stored procedure executed with the 'OWNER privilege. Then, grant the necessary privileges to those roles.
B. Use a UDF to create the roles and grant privileges. This UDF should be owned by the application and be executed with CALLER's rights.
C. Dynamically generate SQL statements within the setup script based on a configuration table stored within the application package, then execute these statements to create the roles and grant privileges.
D. Instruct consumers to manually create the roles and grant privileges after installation, providing them with a separate documentation file containing the necessary SQL commands.
E. Use a 'CREATE ROLE IF NOT EXISTS' statement within the setup script, followed by 'GRANT statements using the 'APPLICATION' keyword to avoid granting privileges directly to the role within the provider account.

Answer: E

Explanation:
Using 'CREATE ROLE IF NOT EXISTS and granting privileges using the 'APPLICATION' keyword is the most secure and efficient approach. It automates role creation during setup, avoids hardcoding sensitive information, and leverages the application-centric security model of Snowflake Native Apps. Granting privileges to a role within the provider account is generally discouraged for native apps, as it can potentially expose the provider's internal data. Using the APPLICATION keyword ensures the privileges are scoped to the application's context within the consumer's account.

NEW QUESTION # 154
You've deployed a Snowflake Native Application to the Marketplace. A consumer reports an issue, and after investigating, you suspect a vulnerability related to SQL injection within a stored procedure. You want to implement best practices to mitigate this risk. Which of the following strategies are recommended to secure the stored procedure against SQL injection?

A. Encode all user input before inserting it into SQL queries to neutralize potentially harmful characters.
B. Grant 'OWNERSHIP' privilege to the stored procedure to prevent unauthorized modifications.
C. Use parameterized queries or prepared statements whenever possible to prevent user input from being directly interpreted as SQL code.
D. Implement strict input validation and sanitization to ensure that user input conforms to expected data types and patterns.
E. Disable all external network access from within the stored procedure environment.

Answer: A,C,D

Explanation:
SQL injection vulnerabilities arise when user input is incorrectly incorporated into SQL queries. Parameterized queries (A) and input validation/sanitization (B) are crucial defenses. Parameterized queries treat input as data, not code, preventing injection. Input validation ensures only expected data reaches the query. Encoding user input (D) neutralizes harmful characters that could be exploited. Granting 'OWNERSHIP' (C) is for access control, not injection prevention. Disabling network access (E) might improve overall security but doesn't directly address SQL injection within the procedure.

NEW QUESTION # 155
You are developing a Snowflake Native App that requires specific Snowflake features and functionalities. To ensure compatibility and proper execution across different consumer environments, you need to define the minimum required Snowflake version. Which section in the manifest file is used to specify the minimum Snowflake version required by the application and what is the correct syntax?

A. The 'dependencies' section. Syntax: '"dependencies": [{"snowflake_version":">=7.0"}]
B. The 'configuration' section. Syntax: '"configuration": {"required_snowflake_version": "7.0"}'
C. The 'api_version' section. Syntax: '"api_version": along with in the 'applications section.
D. The 'setup' section. Syntax:
E. The 'application' section. Syntax: '"application": {"min_snowflake_version": "7.0"}'

Answer: E

Explanation:
The 'application' section within manifest file is used to specify minimum snowflake version required by Snowflake Native Application with the syntax '"application": {"min_snowflake_version": "7.0"}'. This attribute ensures that app installed is compatible with consumer account.

NEW QUESTION # 156
You're developing a Snowflake Native Application with a front-end UI built using Streamlit, deployed as a UDF. This UI allows users to upload CSV files for processing. To adhere to security best practices and prevent unacceptable code practices in a Native App, what considerations should you prioritize in your development and deployment process specifically related to handling user-uploaded files ?

A. Implement strict file size limits and file type validation on both the client-side (Streamlit UI) and server-side (Snowflake UDF) to prevent denial-of-service attacks and malicious file uploads. Sanitize and validate the contents of the uploaded CSV file, escaping special characters and preventing SQL injection vulnerabilities if data from the CSV is used in SQL queries.
B. Allow user to execute scripts or upload executable file as part of CSV content
C. Disable any logging or auditing of file upload activity to protect user privacy and avoid unnecessary data storage.
D. Assume that all uploaded files are safe and trustworthy, and directly process them without any security checks.
E. Store the uploaded CSV files directly within a Snowflake table without any validation to ensure high performance and minimal overhead.

Answer: A

Explanation:
Option A is the most secure approach. It emphasizes both client-side and server-side validation to prevent malicious uploads. Storing files directly without validation (B) is highly insecure. Disabling logging (C) hinders auditing and incident response. Assuming files are safe (D) is a critical security flaw. Option E is very dangerous from security perscpective, it should not be allowed.

NEW QUESTION # 157
You are developing a Snowflake Native Application that utilizes a Streamlit frontend. The application requires access to specific data in the consumer account. You've already defined the necessary roles in your provider account. Which of the following steps are absolutely necessary to grant the Streamlit application the appropriate permissions to access the consumer's data? Assume the provider account has already shared the application package.

A. In the consumer account, grant the 'IMPORTED PRIVILEGES privilege on the application package to a role that Streamlit will assume. Ensure the Streamlit application has code to execute 'snowflake.connector.connect()' with the correct consumer account credentials.
B. Create a new database role in the provider account and grant the necessary privileges (e.g., 'SELECT on tables) to this role. Share this database role to the consumer account using secure data sharing. No code changes are needed in the Streamlit application.
C. Within the application package installation script, grant the necessary privileges (e.g., 'SELECT on tables) directly to the 'APPLICATION' object representing the installed application using 'GRANT ON TO APPLICATION In the consumer account, no further privilege grants are required. Also ensure to 'GRANT APPLICATION ROLE app_public TO APPLICATION'
D. Define an application role in the application package and grant the necessary privileges within the package installation script using 'GRANT APPLICATION ROLE TO SHARE. In the consumer account, grant the application role to a user. No code changes are needed in the Streamlit application. Ensure to also grant the application role to the application in the install script with 'GRANT APPLICATION ROLE TO APPLICATION
E. In the consumer account, create a new application role and grant the necessary privileges (e.g., 'SELECT on tables) to this role. In the Streamlit code, use streamlit.experimental_get_query_params()' to pass the role name as a query parameter to the application.

Answer: C,D

Explanation:
Options C and E are the most accurate. Option C is correct because it leverages application roles, which are the recommended way to manage privileges in Snowflake Native Apps. Granting the application role to a user in the consumer account allows them to access the data via the application. Option E is correct because granting privileges directly to the 'APPLICATION' object is essential for the application to function correctly with its own access rights. Additionally, granting 'app_public' ensures basic functionality is available to the application. Option A is incorrect because applications should not be connecting to the database using standard connectors with explicit credentials in Native Apps. Option B is incorrect because passing role names as query parameters is not a secure or recommended practice. Option D is incorrect because sharing a database role directly is not the appropriate mechanism for granting access within a Snowflake Native App. The application package and its associated roles should manage the access.
