Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題 (Q128-Q133):

質問 # 128
An application provider, 'SecureData Solutions', wants to implement an in-app share within their Snowflake Native App. They intend to share a specific, filtered subset of a provider-owned table with consumers to enhance app functionality without exposing the entire dataset. Which of the following steps are REQUIRED to properly configure and utilize this in-app share?

A. Create a secure view on the provider-owned table with the desired filters, create a share in the provider account, grant usage on the database and schema containing the secure view to the share, and then grant SELECT privilege on the secure view directly to the share. Lastly, grant OWNERSHIP on the SHARE to the application role.
B. Create a database role in the provider account, grant SELECT privilege on the filtered view of the table to this database role, and then create a share and grant usage to this role.
C. Create a database role in the provider account, grant SELECT privilege on the base table to the role, then create a SHARE and add the role to the SHARE as a privileged principal.
D. Create a share in the provider account, grant usage on the database and schema containing the table to the share, and then grant SELECT privilege on the filtered view of the table directly to the share.
E. Create a secure view on the provider-owned table with the desired filters, create a database role in the provider account, grant SELECT privilege on the secure view to this database role, create a share, and grant usage to the role. Lastly, grant OWNERSHIP on the SHARE to the application role.

正解：A

解説：
In-app sharing requires using secure views for filtering. A share is created, and usage rights on the database and schema containing the secure view must be granted to the share. Then, SELECT privilege on the secure view is granted to the share directly. Finally, OWNERSHIP on the SHARE is granted to the application role. Database Roles cannot be directly be granted to share, as shares need access to concrete securable objects, views or tables.

質問 # 129
You are developing a Snowflake Native Application that requires secure access to external services for data enrichment. You choose to implement an External Function with API Integration. Which of the following security best practices are MOST important to implement when configuring the API Integration and the External Function to minimize security risks?

A. Store any sensitive credentials required by the external service directly in the External Function's code body for easy access.
B. Disable network policies on the API Integration to avoid accidental blocking of traffic.
C. Configure 'AWS IAM ROLE ARNS or similar parameters (depending on cloud provider) to grant Snowflake the least privilege access to the specific resources on the external service required by the function.
D. Use the parameter in the API Integration to restrict access to only the trusted IP addresses of the external service.
E. Grant usage on the API integration to PUBLIC role to allow all users to invoke the external function.

正解：C、D

解説：
Options B and D are correct. Using restricts the allowed source IPs for connection to the External Function, reducing the attack surface. Using SAWS IAM ROLE ARN' (or equivalent) with the principle of least privilege ensures that Snowflake only has the necessary permissions on the external service, minimizing the potential impact of a compromised function. Option A is incorrect because granting usage to PUBLIC is a security risk. Option C is incorrect because storing credentials directly in code is a bad practice. Option E is incorrect because network policies should be in place for security. The other options either create a broad attack surface or directly expose sensitive information.

質問 # 130
You are developing a Snowflake Native Application that uses a custom Python handler to perform data transformations. This handler requires access to a third-party Python package not included in the standard Anaconda environment provided by Snowflake. To ensure the application functions correctly on consumer accounts, what steps must you take? (Select all that apply)

A. Specify the Python package as a dependency in the application's setup script using a install command.
B. Create a stage and upload the python package(s). Then in the Python UDF code, reference the python package from the stage.
C. Include the required Python package in the application package as a zip file using the 'CREATE or REPLACE FUNCTION' command with the 'imports' clause.
D. Instruct consumers to manually install the necessary Python package using 'pip install' in a Snowflake Snowpark Python worksheet after installing the application.
E. Use the SALTER FUNCTION' command after installation on the consumer's account to add the required Python package to the function definition. This option is not possible.

正解：B、C

解説：
Snowflake Native Applications cannot rely on consumers manually installing dependencies or executing arbitrary shell commands for security reasons. Including the Python package as a zip file via the 'imports' clause within the 'CREATE or REPLACE FUNCTION' command ensures that the dependency is automatically available when the Python handler is executed within the application environment on the consumer's account. Option C is not a valid command and not permissible in Snowflake. Also, consumers cannot use alter after the installation, Hence it will not work. A and D are the correct choices.

質問 # 131
You are developing a Snowflake Native Application that uses a Stored Procedure to orchestrate complex data processing tasks. This stored procedure is defined within the application package. When testing in test mode, which of the following security considerations are paramount to ensure the procedure executes correctly and securely, without unintentionally granting excessive privileges to the consumer?

A. Create a dedicated service user specifically for the application and grant only the necessary privileges to this user. The stored procedure should then execute with the privileges of this service user using the 'EXECUTE AS CALLER clause. This allows granular access control.
B. Ensure that any roles granted to the application role also have the necessary privileges to execute the stored procedure, and access the objects it interacts with. The stored procedure must be defined with 'EXECUTE AS CALLER.
C. Define the stored procedure with the 'EXECUTE AS OWNER clause. This ensures the procedure always runs with the privileges of the application owner, regardless of the caller's permissions.
D. Since the application is running in test mode, security is not a major concern. Granting all necessary privileges directly to the application role simplifies testing without compromising the consumer's security.
E. Grant the 'EXECUTE' privilege on the stored procedure to the 'PUBLIC' role during test mode. This simplifies testing but should be revoked before publishing the application.

正解：B

解説：
Option D is correct because using 'EXECUTE AS CALLER grants privileges based on the caller's role, not the owner of the procedure. It also emphasizes the principle of least privilege. 'EXECUTE AS OWNER will not work in Native Apps. Option C is incorrect because granting privileges to PUBLIC is not a good practice. Option E is incorrect because security matters in Test Mode.

質問 # 132
You are developing a Snowflake Native Application that interacts with a user-provided data source. The application needs to validate that the user has granted the necessary permissions on their dat a. The application package contains the following setup script:

Which of the following approaches is the MOST secure and reliable way to check for SELECT privileges within the procedure?

A. Use function with appropriate parameters to directly check if the 'app_role' has SELECT privilege on 'user schema.user table'.
B. Use 'SHOW GRANTS TO ROLE app_role' and parse the output to see if SELECT privilege on 'user_schema.user_table' exists.
C. Attempt a 'SELECT COUNT( ) FROM within a "TRY...CATCH' block and infer permissions based on the error message.
D. Query the 'INFORMATION SCHEMA.TABLE PRIVILEGES' view to check if 'app_role' has SELECT privilege on 'user_schema.user_table'.
E. Assume SELECT privileges are granted as part of the application installation process without explicit validation.

正解：A

解説：
'SYSTEM$PRIVILEGE_CHECK' is the recommended and most secure method. It directly checks for the existence of a specified privilege for a role on an object. Parsing the output of 'SHOW GRANTS' is less reliable and prone to errors. 'TRY...CATCH' is inefficient and relies on error message parsing, which is discouraged. provides metadata but not a definitive check in the context of the application role having the necessary grants made by the consumer. Assuming privileges are granted is a security risk.
