問題 #231
You are developing a Snowflake Native Application that needs to securely access data in a consumer's account. The application requires the consumer to grant specific privileges to a custom role created and managed within the application package. Which of the following steps are absolutely essential for correctly configuring the application package to ensure this secure data access, and how should the setup script handle the privilege granting?

A. Utilize a service account to access the data, providing the service account's credentials as part of the application setup. The application will then use the service account to access the consumer's data.
B. Define the required privileges in the application package manifest (snowflake.yml). Ensure that the setup script includes commands to grant the specific privileges on the consumer's data to the application's custom role, using 'GRANT ON TO ROLE within an EXECUTE IMMEDIATE statement in the setup script. The setup script should also define the application role.
C. Grant the 'USAGE privilege on the consumer's database and schema to the application's role within the setup script. This implicitly allows the application to read all data within that schema.
D. The consumer must manually grant the necessary privileges to the application's role after the application is installed, as the application package cannot automatically modify the consumer's security settings.
E. Create a share from the provider account to the consumer account, granting the consumer read access to the application package's data. Then, use a setup script to grant ownership of the data to the application role after installation.

答案：B

解題說明：
Option B is correct because it outlines the necessary steps for secure data access in a Snowflake Native Application. The application package manifest informs Snowflake about the app's requirements. The setup script handles granting privileges using EXECUTE IMMEDIATE' because the application role doesn't exist in the consumer account until installation. Options A, C, D, and E are incorrect because they either describe insecure practices, inaccurate assumptions about application capabilities, or fail to address the secure granting of privileges to the application's role within the consumer's environment. Shares are not used to grant privileges to roles in the consumer account; privileges must be granted directly. Consumers are not typically required to manually grant privileges. Service accounts are not a supported method. 'USAGE' does not provide read access to the tables.

問題 #232
A Snowflake Native App developer is creating an application that accesses a secured table 'CUSTOMER DATA' within the provider's account. The developer wants to grant the consumer read-only access to this table through the application, but only after the application is installed and the consumer has accepted the terms and conditions. Which of the following steps are necessary to achieve this goal? (Choose two)

A. The provider creates a versioned schema in the listing and shares it with the consumer account. Once the consumer accepts the terms and conditions, the provider executes 'GRANT SELECT ON TABLE CUSTOMER_DATA TO APPLICATION ROLE app_role' within the consumer account using a secure UDF.
B. Define a stored procedure within the application package that, upon execution in the consumer account (post-installation), executes a 'GRANT SELECT ON TABLE CUSTOMER_DATA TO APPLICATION ROLE app_role' statement. The application itself doesn't directly share the data; the procedure manages the access.
C. Create a share from the provider account containing the 'CUSTOMER_DATA table and grant the consumer account access to this share using the Snowsight UI, specifically setting the ' READ ONLY' privilege on the table after the application is installed.
D. Create an outbound share within the application that shares the 'CUSTOMER DATA' table with a specific application role. Configure an activation hook that runs post-installation to grant the 'SELECT' privilege on the table to the application role using the 'GRANT' command.
E. Define a manifest file within the application package that specifies the 'CUSTOMER DATA' table as a resource and declares the 'SELECT privilege required by the application. Snowflake automatically grants this privilege to the application's default role upon installation.

答案：B,D

解題說明：
Option B is correct because it leverages a stored procedure executed in the consumer account to grant the required privilege to the application role. This allows for conditional granting post-installation. Option D is also correct because it uses an outbound share and activation hook, which is a standard mechanism for granting access to objects in the provider account to application roles in the consumer account after the application is installed.

問題 #233
You are preparing to list your Snowflake Native Application on the Snowflake Marketplace. You want to restrict its availability to specific Snowflake regions and also require consumers to agree to a custom End User License Agreement (EULA) before installation. Which steps are essential during the listing creation process to achieve this?

A. Configure the 'Availability' section of the listing to specify allowed regions. Upload the EULA as a PDF document within the 'Documentation' section.
B. Use the Snowflake CLI to programmatically set the allowed regions using the 'snowflake marketplace application update' command. Include a link to an external website hosting the EULA in the listing description.
C. During listing creation, select the 'Custom EULA' option and provide the EULA text directly within the designated field. Configure the 'Availability' section to specify the allowed regions.
D. Regions are inherently globally available so it cannot be restricted. Include the EULA within the code of the application, forcing the user to acknowledge it through the code.
E. Specify the allowed regions in the 'Availability' section of the listing. Upload a text file containing the EULA and mark it as 'Required Agreement' in the listing settings.

答案：C

解題說明：
Option D is the correct answer. The Snowflake Marketplace provides specific fields to enter a custom EULA directly. Also the availability of the application can be restricted based on Snowflake regions. Options A, B, and C provide partially correct steps, but do not cover the complete solution. A PDF or link doesn't guarantee agreement. Option E has a false statment that regions cannot be restricted.

問題 #234
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. Storing all application data within the provider account and accessing it directly from the consumer account using data sharing to avoid data duplication.
B. Minimizing data transfer between the provider and consumer accounts by leveraging Snowpark and UDFs for data processing within the consumer's environment.
C. Implementing robust error handling and logging mechanisms to facilitate debugging and monitoring of the application's behavior in both the provider and consumer environments.
D. Using secured API integration to call the external APIs to get real time details in the app to make the app more useful.
E. 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.

答案：B,C,E

解題說明：
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.

問題 #235
You are designing a Snowflake Native App that interacts with sensitive customer dat a. You need to ensure that the application only accesses the data it absolutely needs and adheres to the principle of least privilege. Which of the following strategies are crucial for maintaining data security within your application?

A. Create specific roles with granular access privileges (e.g., 'SELECT on specific columns) and grant these roles to the application's managed service account.
B. Implement data masking policies to redact sensitive information before it's accessed by the application.
C. Utilize Snowflake's secure UDFs with invoker's rights to perform data transformations and access control based on the user's role.
D. Store sensitive customer data directly within the application package to avoid external access.
E. Grant the application role the 'OWNERSHIP' privilege on all tables containing customer data.

答案：A,B,C

解題說明：
Options B, C, and E are essential for data security. Granting granular privileges (B) minimizes the attack surface. Data masking (C) prevents direct exposure of sensitive information. Secure UDFs with invoker's rights (E) enforce access control at the function level. Option A grants excessive privileges. Option D is an anti-pattern, as application packages should not store persistent data.
