최신 SnowPro Core Certification NAS-C01 무료샘플문제 (Q69-Q74):

질문 # 69
You are developing a Snowflake Native Application that uses Streamlit to provide a user interface for data analysts. The application accesses sensitive customer data residing in a managed database. To enhance security, you want to implement row-level security (RLS) based on the user's role. You have the following Streamlit code snippet:

Which of the following actions should you take to implement RLS in the Snowflake Native App, ensuring only authorized users can view specific rows of 'customer_data'? Assume the already contains necessary credentials. Choose the most secure and efficient method.

A. Implement RLS directly within the Streamlit application by filtering the 'data' DataFrame based on the user's role before displaying it using 'st.dataframe'. Store user roles in a separate table and fetch them using a different database connection.
B. Create a secure view in Snowflake that implements RLS based on the role of the user executing the query. Grant the Streamlit user access to this view instead of the base table, and modify the 'get_data' function to query the view.
C. Implement a custom Python decorator that checks user roles before executing the 'get_data' function. Raise an exception if the user lacks the necessary role.
D. Modify the SQL query within the 'get_data' function to include a 'WHERE clause that filters data based on the current Streamlit user's username obtained using 'st.session_state.user.username' .
E. Use Snowflake's masking policies combined with a secure view. The masking policy reveals data based on the user's role. Grant the Streamlit application's role access to the secure view.

정답：E

설명：
Using Snowflake's masking policies and secure views is the most secure and efficient method. It centralizes RLS within Snowflake, leveraging its security features. Option A is vulnerable to SQL injection if 'st.session_state.user.username' is not properly sanitized. Option B is better, but masking policies provide more granular control and data obfuscation. Option C pushes security logic to the application layer, which is less secure. Option E adds unnecessary complexity and overhead.

질문 # 70
You are developing a Streamlit application within a Snowflake Native Application that needs to access a secured view named 'sensitive_data' in the application's container. This view exposes aggregated and anonymized dat a. What minimum set of privileges must be granted to the 'app_public' application role to allow users to query this view from the Streamlit application?

A. GRANT USAGE ON SCHEMA application TO APPLICATION ROLE app_public; GRANT ALL PRIVILEGES ON VIEW application.sensitive_data TO APPLICATION ROLE app_public;
B. GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
C. GRANT USAGE ON DATABASE TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
D. GRANT USAGE ON DATABASE .application TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;
E. GRANT USAGE ON SCHEMA application TO APPLICATION ROLE app_public; GRANT SELECT ON VIEW .application.sensitive_data TO APPLICATION ROLE app_public;

정답：E

설명：
The correct answer is B. To access a view, you need 'SELECT privilege on the view itself and USAGE privilege on the schema containing the view. 'APPLICATION' schema is the automatically generated schema, and should be used. Option A is incorrect because the USAGE privilege should be granted on the schema, not the database. Option C is incorrect because the USAGE privilege is needed on the schema, not just the database. Option D is incorrect because granting ALL PRIVILEGES is generally not a best practice for security and not needed. Option E is incorrect because you must grant usage on the Schema.

질문 # 71
When designing the architecture of a Snowflake Native App, which of the following architectural considerations and trade-offs should you carefully evaluate to optimize performance, security, and cost-effectiveness? (Select all that apply)

A. Minimizing data transfer between the provider and consumer accounts by leveraging Snowpark and UDFs for data processing within the consumer's environment.
B. Using secured API integration to call the external APIs to get real time details in the app to make the app more useful.
C. Choosing the appropriate data access model (e.g., UDFs, stored procedures, Snowpark) based on the specific use case and performance requirements, considering the overhead associated with each approach.
D. Storing all application data within the provider account and accessing it directly from the consumer account using data sharing to avoid data duplication.
E. Implementing robust error handling and logging mechanisms to facilitate debugging and monitoring of the application's behavior in both the provider and consumer environments.

정답：A,C,E

설명：
Options A, D, and E are crucial for optimal Snowflake Native App design. Minimizing data transfer (A) reduces costs and improves performance. Robust error handling and logging (D) are essential for debugging and monitoring. Choosing the correct data access model (E) is a key performance factor. Option B is incorrect because storing all data in the provider account and sharing to the consumer introduces unnecessary dependencies and potential security risks. Consumers also need to pay for querying your shared data. Option C is not always desirable, since calling external API every time would be too expensive.

질문 # 72
You are designing a Snowflake Native Application that requires fine-grained access control to its data within the consumer account. You want to ensure that consumers can only access data relevant to their specific department. Which of the following Snowflake features, when combined, offer the MOST secure and flexible solution for implementing this requirement within the context of a Snowflake Native Application ?

A. External Tables and Secure Views with Owner's Rights.
B. Row Access Policies and Secure Views with Caller's Rights.
C. Views and Stored Procedures with Caller's Rights.
D. Dynamic Data Masking policies and Views with Caller's Rights.
E. User-Defined Functions (UDFs) and Row Access Policies.

정답：B

설명：
The best combination is Row Access Policies and Secure Views with Caller's Rights. Row Access Policies: Allow you to filter data based on the user accessing it, ensuring they only see data relevant to their department. Policies are applied to tables. Secure Views with Caller's Rights: Allow you to encapsulate the data access logic, ensuring that the row access policies are always enforced, and that consumers cannot bypass them. Caller's rights are essential here, as the access control decisions need to be made based on who is using the view. The other options are less suitable: A: Views and Stored Procedures can enforce access, but without Row Access Policies, they're less secure. B: UDFs can manipulate data but don't inherently enforce row-level security like Row Access Policies. C: External Tables are for data outside Snowflake; Owner's Rights are less secure than Caller's Rights in this scenario. E: Dynamic Data Masking hides data, it doesn't filter it, so it won't restrict access to specific rows.

질문 # 73
A Snowflake Native App provider wants to grant a consumer access to a secure view within their application. The provider's application package is named and the secure view is named 'sensitive_data_view'. The consumer's account identifier is 'XYZ12345'. Which of the following is the MOST secure and appropriate method to grant this access using Snowflake's Native App Framework?

A. Grant imported privileges on my_app_package to share with account XYZI 2345;
B. Grant SELECT on sensitive data view to account XYZ12345;
C. Grant USAGE on database containing sensitive_data_view to account XYZI 2345;
D. Create a share and grant SELECT on sensitive_data_view to the share, then grant usage on the share to account XYZI 2345;
E. Create a role within the application package, grant SELECT on sensitive_data_view to the role, and create an authorization grant to account XYZ12345 for that role.

정답：E

설명：
The most secure approach is to create a role within the application package specifically for accessing the secure view. By using an authorization grant, you explicitly control which consumer accounts can assume this role and access the view. Granting privileges directly to accounts or using shares is less secure and more difficult to manage in the context of a Native App. IMPORTED PRIVILEGES apply at the package level and are needed for a consumer to access the application, but aren't granular enough for specific objects.
