問題 #54
You are creating a Snowflake Native Application that includes a stored procedure to process sensitive dat a. The procedure needs to access data from a table owned by the application package and write processed data to a table in the consumer's account. The data in the consumer's table must only be accessible by authorized roles within the consumer's account, not directly by the application itself. Which of the following approaches ensures the MOST secure and controlled access to the consumer's data?

A. Implement an API endpoint within the application package that the consumer can call to retrieve the processed data.
B. Store the processed data in an intermediate stage accessible to both the application and the consumer.
C. Create a secure view on the consumer's table and grant the APPLICATION' role 'SELECT privileges on the view.
D. Grant the 'APPLICATION' role direct 'SELECT and 'INSERT privileges on the consumer's table.
E. Use the EXECUTE AS CALLER clause for the stored procedure, requiring the consumer to grant the necessary privileges to a role that executes the procedure.

答案：E

解題說明：
'EXECUTE AS CALLER is the most secure approach. It forces the stored procedure to execute with the privileges of the caller (the consumer's role). The consumer must grant a specific role the necessary privileges on their table, giving them full control over who can access the data. Granting direct privileges to the 'APPLICATION' role compromises security. Secure views can still expose data, and an API endpoint adds unnecessary complexity. An intermediate stage creates a potential security vulnerability and requires additional management.

問題 #55
A consumer wants to install a Snowflake Native App. They have already identified the app in the Snowflake Marketplace. After attempting to install the application, they receive an error stating 'Insufficient privileges to install application'. Which of the following steps are MOST likely required to resolve this issue? (Select Two)

A. The consumer's account administrator needs to grant the 'CREATE APPLICATION' privilege to the role used by the consumer attempting to install the application.
B. The consumer needs to have the 'CREATE APPLICATION PACKAGE privilege on the target account.
C. The application provider needs to grant the 'IMPORTED PRIVILEGES to the consumer account.
D. The application provider needs to explicitly share the application package with the specific role the consumer is using for installation.
E. The consumer's account administrator needs to grant the 'APPLY APPLICATION' privilege to the role used by the consumer attempting to install the application.

答案：A,E

解題說明：
The 'APPLY APPLICATIONS privilege is required to install an application from the Snowflake Marketplace. The 'CREATE APPLICATION' privilege is needed to create the application object in the consumer account during installation. Option B is incorrect because 'IMPORTED PRIVILEGES is used by the provider to grant access. Option C is wrong because 'CREATE APPLICATION PACKAGE is for providers. Option E is incorrect; applications are shared via the marketplace.

問題 #56
You are developing a Snowflake Native Application that requires maintaining multiple live versions for different customer segments. Some customers need to stay on an older version for compatibility reasons, while new customers should use the latest version. How can you best manage these different versions using Snowflake Native App features?

A. By using streams and tasks to replicate data and logic between different versions of the application, ensuring data consistency.
B. By implementing a custom versioning system within the application's stored procedures and functions, relying on consumer-provided parameters to determine which version of the logic to execute.
C. By leveraging the 'APPLICATION ROLE to control access to different versions using conditional logic within the application code.
D. By creating separate Snowflake accounts for each customer segment, each with a different version of the application installed.
E. By creating separate application packages for each version and managing them independently, allowing consumers to choose which version to install. The 'APPLICATION ROLE is used to define application-level access.

答案：E

解題說明：
The correct answer is (C). Snowflake Native Apps allow you to create separate application packages for each version. Consumers can then choose the version that best suits their needs. Using the 'APPLICATION ROLE allows for controlling access to different resources within the application, ensuring proper data governance and security. Options A, D, and E are less efficient or not directly supported by the Snowflake Native App framework. Option B is partially correct that you can leverage application role but version control is through separate application packages.

問題 #57
You are developing a Snowflake Native Application that provides data transformation services. You want to provide example SQL scripts to consumers within the application package to showcase how to use the application's functions. Where should these example scripts be stored to ensure they are accessible to consumers upon installation?

A. Store the example SQL scripts as files within the application package itself (e.g., in a 'scripts' directory) and use relative paths to access them from within the application code.
B. Store the example SQL scripts in a separate stage within the provider account and grant USAGE on the stage to the application role.
C. Embed the example SQL scripts directly as string literals within the setup script.
D. Store the example SQL scripts in a table within the application database and provide a view to access them.
E. Store the example SQL scripts in an external stage (e.g., AWS S3) and provide instructions to the consumer to load them.

答案：A

解題說明：
Storing the scripts within the application package (Option B) ensures that they are always available to the consumer as part of the application installation. Relative paths allow the application code to access them directly. Option A requires additional permissions setup. Option C is not suitable, it is not meant for storage of scripts like that. Option D makes the setup script excessively long and hard to maintaim Option E requires additional setup and is not self-contained.

問題 #58
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. 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.
B. Grant usage on the API integration to PUBLIC role to allow all users to invoke the external function.
C. Store any sensitive credentials required by the external service directly in the External Function's code body for easy access.
D. Disable network policies on the API Integration to avoid accidental blocking of traffic.
E. Use the parameter in the API Integration to restrict access to only the trusted IP addresses of the external service.

答案：A,E

解題說明：
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.

問題 #59
