Snowflake SnowPro Specialty - Native Apps NAS-C01 Prüfungsfragen mit Lösungen:

1. You are developing a Snowflake Native Application that processes sensitive financial data. You need to implement robust logging and auditing to comply with regulatory requirements. Which of the following strategies would provide the MOST secure and comprehensive auditing and logging solution within the context of a Snowflake Native App?

A) Implement logging to an external service such as AWS CloudWatch or Azure Monitor, streaming data directly from UDFs using external functions. Implement data redaction within the UDFs before sending data externally.
B) Use Snowflake's stages to write the event logs and then create the external table on top of it to process the data.
C) Rely solely on Snowflake's ACCOUNT_USAGE views and information schema tables within the consumer account.
D) Utilize Snowflake's Event Tables to capture application events. Ensure proper role-based access control is in place to restrict access to the event data within the provider account. Masking and Row Access policies should be applied before writing to event tables.
E) Implement custom logging using UDFs that write directly to a table accessible only within the provider account. Use masking policies to protect sensitive data before logging.

2. A customer is attempting to install your Snowflake Native Application from the Snowflake Marketplace, but the installation fails. You need to troubleshoot the issue. Which of the following steps would provide the most direct and relevant information for diagnosing the cause of the installation failure?

A) Examine the application's code repository for any recent changes that might have introduced errors.
B) Review the Snowflake Marketplace listing details to ensure all required components and dependencies are accurately specified.
C) Check the Snowflake system status page for any reported outages or incidents that might be affecting the Marketplace.
D) Ask the customer to share their Snowflake account identifier to check internal logs.
E) Query the view in the consumers account to retrieve detailed information about the installation attempt, including error messages and status codes.

3. You are developing a Snowflake Native Application that requires specific roles to be assigned to consumers upon installation. Your setup script needs to automatically create these roles if they don't exist and grant appropriate privileges on application objects. Which of the following approaches is the MOST secure and efficient way to achieve this, assuming you want to minimize the attack surface?

A) Hardcode the role names in the setup script and create them using a stored procedure executed with the 'OWNER privilege. Then, grant the necessary privileges to those roles.
B) Use a UDF to create the roles and grant privileges. This UDF should be owned by the application and be executed with CALLER's rights.
C) Dynamically generate SQL statements within the setup script based on a configuration table stored within the application package, then execute these statements to create the roles and grant privileges.
D) Instruct consumers to manually create the roles and grant privileges after installation, providing them with a separate documentation file containing the necessary SQL commands.
E) Use a 'CREATE ROLE IF NOT EXISTS' statement within the setup script, followed by 'GRANT statements using the 'APPLICATION' keyword to avoid granting privileges directly to the role within the provider account.

4. You are preparing a Snowflake Native Application for its initial release. You have a 'setup.sqP file that creates necessary tables and roles. You are also planning for future updates. Which of the following practices will BEST ensure smooth, version-upgrade compatible deployments for your application's consumers?

A) Always drop and recreate all application objects in each new version's 'setup.sqr to ensure a clean slate.
B) Avoid using 'CREATE OR REPLACE TABLE in 'setup.sqr and always use 'CREATE TABLE IF NOT EXISTS.
C) Use a consistent naming convention for all application objects and clearly document any breaking changes in release notes.
D) Use stored procedures within 'setup.sqr to encapsulate schema changes and data migrations, making them idempotent.
E) Include detailed comments in 'setup.sql' explaining the purpose of each SQL statement and the logic behind schema changes.

5. A Native Application developer is creating a data product to be sold on the Snowflake Marketplace. The application needs read access to a shared database called 'RETAIL DATA'. The application logic includes a function that reads a lookup table, 'PRODUCT CATEGORIES', within this shared database. Which sequence of actions, executed by the application provider, ensures the application can access this table at installation time and after updates, following least privilege principles?

A) Grant 'SELECT on to the application role during the application's setup script. Do not grant 'IMPORTED PRIVILEGES' on the database.
B) Grant USAGE on ' RETAIL_DATX to the application role during the application's setup script. Do not grant 'IMPORTED PRIVILEGES' on the database.
C) Grant 'IMPORTED PRIVILEGES' on 'RETAIL DATA to the application role. Rely on the consumer to grant 'SELECT access to tables within 'RETAIL DATA' to the application role.
D) Grant 'IMPORTED PRIVILEGES' on 'RETAIL DATA' to the application role. The application setup script should also GRANT USAGE on database RETAIL_DATA and then GRANT SELECT on to the application role.
E) Grant 'IMPORTED PRIVILEGES' on to the application role. Grant 'SELECT on to the application role during the application's setup script.
