최신 SnowPro Core Certification NAS-C01 무료샘플문제 (Q42-Q47):

질문 # 42
Consider the following SQL code snippet within a Snowflake Native Application:

A. The statement will fail because the READ SESSION' privilege is not automatically granted to stored procedures. You must explicitly grant the privilege to the stored procedure's owner.
B. The statement will execute successfully, returning the session ID of the current session in which the stored procedure is running, provided the Native App has the 'READ SESSION' privilege (implicitly or explicitly).
C. The statement will execute successfully, returning the session ID of the current session in which the stored procedure is running, provided the caller has USAGE privilege on the database.
D. The statement will execute successfully, but the 'session_id' will always be null as the 'READ SESSION' privilege does not apply within stored procedures.
E. The statement will execute successfully, returning the session ID of the user who installed the Native Application.

정답：B

설명：
The ' READ SESSION' privilege, if granted to the Native App (either implicitly or explicitly, depending on how it's managed within the app package), allows access to session-related information within the app's context. The session ID will correspond to the current execution context of the stored procedure. Options A and B are incorrect because 'READ SESSIONS does apply within stored procedures if properly authorized. Option C is incorrect as Native app will work on their own context, not the end user context and Option D incorrect as only app owner can use this privilege.

질문 # 43
You're building a Streamlit application within a Snowflake Native App that uses the Permissions API (hypothetical) to control access to sensitive dat a. Your security team has mandated that any changes to data access privileges must be audited. How can you effectively log all privilege grant and revoke operations performed via the Permissions API within your Streamlit application running inside Snowflake, assuming you are given the hypothetical 'PermissionsClient' and methods as below?

A. Leverage Snowflake's built-in 'QUERY _ HISTORY' view to track all SQL commands executed by the Streamlit application. Filter for 'GRANT and 'REVOKE statements to identify privilege changes. Replicate to external storage for retention.
B. Rely solely on the Permissions API's built-in audit trails, assuming it automatically logs all operations to a system table accessible only by Snowflake administrators.
C. Configure Snowflake's event tables for security to track privilege grants and revokes. Create a Streamlit function that fetches and displays these audit events within the application's admin panel. Push data into separate staging area.
D. Implement a custom logging function that captures the API calls and their parameters. Use a try-except block around each API call, logging the details to a separate audit table in Snowflake, and pushing logs to external SIEM tools.
E. Use Snowflake's native logging capabilities in the application's setup script, logging directly to the Snowflake event log. However, these logs may require a system administrator to interpret and extract.

정답：D

설명：
Option A is the most comprehensive approach. It provides the most flexibility and control. By implementing a custom logging function, you can capture the specific details of each API call (including parameters), handle exceptions, and store the audit logs in a dedicated table within Snowflake. This table can then be easily queried, reported on, or integrated with external SIEM (Security Information and Event Management) tools for further analysis and alerting. Option B could be part of the solution, but filtering the QUERY_HISTORY table may not capture all details, especially if using stored procedures. It requires parsing SQL text, which can be brittle. Option C could work for some audit events, but you'd still need to create and manage a process to send these events to an audit log. Option D has limited granularity and security. Relying on Snowflake's native logs provides little control. Option E is incorrect; the hypothetical Permissions API doesn't automatically log actions to a user-accessible system table.

질문 # 44
You are publishing a Snowflake Native Application to the Marketplace. You've completed initial testing, and the application appears to function as expected. However, the security scan consistently fails with a 'Data Exfiltration' error. The application includes a stored procedure that aggregates data from several tables within the application container and writes the results to an external stage using the 'COPY INTO' command. Review the following code snippet:

Which of the following changes is MOST likely to resolve the 'Data Exfiltration' error during the security scan?

A. Implement row-level security policies on the 'aggregated_data' table to restrict access to sensitive rows.
B. Remove the 'GRANT EXECUTE privilege on the 'export_data' procedure from the 'app_public' role.
C. Modify the stored procedure to only export data to a table within the application container instead of an external stage.
D. Require the consumer to explicitly grant the application usage privilege on a secure external stage controlled by the consumer, and modify the procedure to validate the stage's existence and permissions before exporting data.
E. Encrypt the data written to the external stage using client-side encryption with a key managed by the application provider.

정답：D

설명：
The 'Data Exfiltration' error indicates a potential risk of unauthorized data leaving the consumer's Snowflake environment. The root cause is often that the application provider has unrestricted control over where the data is exported. The solution is to require the consumer to control the external stage and explicitly grant the application usage privilege on it. This ensures that the consumer is aware of and approves the data export. Option A would break the functionality. Option B addresses data access within the container but doesn't prevent exfiltration if the application can still write to an uncontrolled stage. Option D adds complexity but doesn't fundamentally address the control issue. Option E restricts functionality unnecessarily.

질문 # 45
You have a Snowflake Native Application that utilizes a managed table. After upgrading your application to version 2.0, some users report that they are missing data in the managed table. After investigation, you realize version 2.0 changed the schema of the managed table and also did not properly migrate all the data from old format into new format. Which of the following steps should be taken to address the missing data after upgrading a Snowflake Native Application?

A. Rollback all users to version 1.0 and then perform the schema migration directly on the consumer's account using custom SQL scripts.
B. Create a new version 2.1. Within version 2.1's setup script, dynamically detect if the application is an upgrade from 1.0 and, if so, execute the data migration script to transfer data from the old schema to the new schema.
C. Create a new version 2.1 that includes a data migration script to transfer data from the old schema (as it existed in version 1.0) to the new schema in version 2.0. Use release directives to upgrade affected users to version 2.1 after staging.
D. Manually insert the missing data into the managed table in each consumer's account, contacting affected users to coordinate the data entry.
E. Since managed tables are fully managed by Snowflake, contact Snowflake support to initiate a data recovery process in each affected consumer account.

정답：B

설명：
Option D is the correct approach. By dynamically detecting the upgrade and running a data migration script, the application ensures data integrity during the upgrade process. The data migration script will convert data from old format to new format. Option A is almost correct, however we don't assume the user is at 1.0. The application may be updated from earlier versions as well. Option B is not feasible due to operational overhead of doing it for each consumers and requires high privilege on consumer side which is not allowed for native apps. Option C is not practical or scalable. Managed tables are managed by your application code within the package, so Snowflake support won't perform data manipulation (Option E).

질문 # 46
You are packaging a Snowflake Native App that includes a Streamlit application for data visualization. The Streamlit application needs to access a table named 'SALES DATA within the app's data container. Which of the following steps are REQUIRED to correctly grant the Streamlit application the necessary permissions to read the data? (Select all that apply)

A. Grant the 'APPLOG' privilege to the application role defined in the setup script on the internal stage.
B. Create a service account within the Snowflake Native App and grant the 'SELECT' privilege on the 'SALES_DATR table to the service account.
C. Grant the 'IMPORTED PRIVILEGES' on the database containing the 'SALES DATA' table to the application role.
D. Grant the 'SELECT privilege on the 'SALES_DATX table directly to the application role defined in the setup script.
E. Create a secure view on the ' SALES_DATX table, using the function in the view definition, and grant the 'SELECT privilege on the secure view to the application role.

정답：B,E

설명：
Snowflake Native Apps require service accounts for components like Streamlit to interact with data securely. Granting SELECT directly to the app role (D) is generally not how applications are structured with secure views. APPLOG (B) is related to logging, not data access. IMPORTED PRIVILEGES (E) is useful when referencing objects from external data sources which is not the case here, the table resides within the applications data container. Using a secure view (C) allows for controlled access and data masking if needed and service account will be used to access it.
