Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題:

1. You are developing a Snowflake Native App that requires accessing sensitive user data within the consumer's account. To ensure data privacy and security, you need to implement appropriate access controls. Which of the following approaches is the MOST secure and recommended way to grant your app access to this data, assuming the data is stored in a table named 'user_data' ?

A) Granting 'USAGE privilege on the 'user_data' table directly to the application role provided by Snowflake Native App Framework.
B) Granting 'SELECT privilege directly on the 'user_data' table to the application role provided by Snowflake Native App Framework.
C) Creating a custom role in the consumer account with 'SELECT privilege on the 'user_data' table and granting that role to the application.
D) Defining a secure view that filters the table based on the application role and granting 'SELECT privilege on the secure view to the application role provided by Snowflake Native App Framework.
E) Using a stored procedure with 'EXECUTE AS CALLER that accesses the 'user_data' table. Grant 'EXECUTE privilege on the stored procedure to the application role.

2. You are developing a Snowflake Native Application and want to implement robust observability and telemetry. Which of the following approaches will enable you to effectively monitor the application's performance, identify errors, and collect usage metrics within the consumer's account?

A) Directly access the consumer's system tables (e.g., 'SNOWFLAKE.ACCOUNT USAGE.QUERY HISTORY) to extract application-related metrics based on query identifiers generated by the application.
B) Rely solely on Snowflake's built-in query history and resource monitoring features in the consumer's account, as these automatically capture all application activity.
C) Utilize to write log data to a secure table within the application and leverage views granted to the consumer to expose relevant metrics and error information. Ensure appropriate roles have access to the views.
D) Implement custom logging using 'SYSTEM$LOG' and store application logs in a separate table within the application's container. Configure grants to allow the application developer to access these logs.
E) The consumer is responsible for implementing observability and telemetry. The application developer cannot implement observability features that function within the consumer's account.

3. Consider the following scenario: You are tasked with designing a setup script for a Snowflake Native Application. This script needs to perform several tasks including creating a database role, granting privileges to the role, and creating a schem a. Your application also provides a configuration table that needs to be populated during the setup process. Which of the following set of statements are true regarding the order of operations and security best practices within the setup script? (Choose all that apply)

A) It is best practice to create the database role before creating the schema, to immediately grant ownership on the schema to the created role.
B) Populating the configuration table should be done before creating any other objects, as other parts of the application might rely on the configuration during object creation.
C) The setup script should always be designed to be idempotent, meaning it can be executed multiple times without causing errors or unintended side effects. Use 'CREATE ... IF NOT EXISTS' where appropriate.
D) When granting privileges to the database role, use the 'APPLICATION' keyword to grant privileges on application objects, enhancing security and control.
E) Setup Scripts should be designed in a way that it requires multiple manual interventions during execution.

4. You're packaging a Snowflake Native Application that performs complex analytical computations on data within the consumer's account. This computation involves several intermediate tables and functions, all created within the application package. You want to optimize the application's performance and reduce storage costs in the consumer's account. Which of the following strategies can be employed to achieve these goals, especially considering that intermediate data is not intended to be directly accessible to the consumer?

A) Implement data pruning techniques within the application's logic to delete intermediate data as soon as it is no longer needed, even if permanent tables are used for intermediate steps.
B) Create all intermediate tables as temporary tables. Temporary tables are automatically dropped at the end of the session, minimizing storage costs and ensuring data privacy.
C) Use external tables to store the intermediate results in cloud storage (e.g., AWS S3), accessed through a secure integration. This minimizes the storage footprint within the consumer's Snowflake account.
D) Create all intermediate tables as standard permanent tables, relying on Snowflake's automatic data compression and storage optimization features to minimize costs. Grant limited privileges to the consumer to control data access.
E) Create all intermediate tables as transient tables. Transient tables do not support Time Travel or Fail-safe, which reduces storage costs, and grant appropriate privileges to application roles.

5. You are developing the setup script for a Snowflake Native Application. The application requires a specific Snowflake Edition (e.g., Enterprise) to function correctly due to certain feature dependencies. How can you ensure that the installation fails gracefully and provides a clear error message if the consumer's account does NOT meet the required edition?

A) Use a configuration file included in the application package to specify the required Snowflake Edition. The setup script reads this file and displays an error message if the edition is not compatible.
B) The Snowflake Marketplace automatically checks for edition compatibility before allowing installation of a Native Application. No explicit checks are needed in the setup script.
C) Use the 'SYSTEM$GET SNOWFLAKE EDITION()' function within the setup script and raise an exception using 'RAISE' if the edition is not compatible. Provide a descriptive error message.
D) Attempt to create objects that are specific to the required Snowflake Edition within the setup script. If the creation fails due to edition limitations, the installation will automatically fail.
E) Include a comment in the setup script indicating the required Snowflake Edition. Rely on the consumer to manually verify their edition before installation.
