Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. A Snowflake Native App provider wants to ensure that even future roles created in their provider account will NOT automatically have access to the application database , which was created without the "MANAGED ACCESS' property initially. After creating a security audit suggested it to be with managed access. Which of the following steps BEST secures the app database?
Note multiple options may be needed

A) DROP DATABASE CREATE DATABASE WITH MANAGED ACCESS;
B) REVOKE USAGE ON DATABASE FROM ROLE PUBLIC;
C) REVOKE ALL PRIVILEGES ON DATABASE FROM PUBLIC;
D) GRANT OWNERSHIP ON DATABASE TO ROLE application_role;
E) ALTER DATABASE SET MANAGED ACCESS = TRUE;

2. You are developing a Snowflake Native Application that provides a data enrichment service. This service requires the consumer to grant the application access to a specific table in their account. You want to ensure that upgrades to your application do not inadvertently break existing consumer configurations. You decide to use a versioned schem a. Which of the following steps are essential during the setup script execution to achieve this and maintain backward compatibility during future upgrades?

A) Create a new unversioned schema named 'APPLICATION' and install all application objects within it. This provides a consistent namespace for all consumers, regardless of the application version.
B) Create a secure view in the versioned schema that accesses the consumer's table. Grant the application role 'SELECT on this secure view. This provides a stable interface that isolates the application from direct changes to the consumer's table.
C) Define a custom role within the application package and grant it the necessary privileges to read the consumer's table via a secure view. Then, grant the application role the USAGE privilege on this custom role. This ensures that the application role can assume the custom role's privileges for data access.
D) Grant the application role 'OWNERSHIP on the consumer's table directly. This allows the application full control and ensures consistent data access regardless of future schema changes within the application.
E) Create a versioned schema using 'CREATE SCHEMA VERSION = ' . Grant the application role 'USAGE on this versioned schema, and ensure all application logic references objects within this schema.

3. A Snowflake Native App provider is troubleshooting an issue where consumer installations intermittently fail. The provider suspects that certain installation parameters are causing conflicts. The provider has implemented an event table to track installation attempts and errors. Which of the following SQL statements is the MOST effective way to identify the installation parameters that are most frequently associated with failed installations? Assume the event table is named "INSTALLATION EVENTS and contains columns 'INSTALLATION ID, 'STATUS' (success/failure), and PARAMETERS' (a VARIANT column storing a JSON object of installation parameters).

A)

B)

C)

D)

E)

4. You are designing a Snowflake Native Application that requires granular control over the privileges granted to different application roles. You want to follow the principle of least privilege. You have the following requirements: Application roles , and app_read_only'. What is the most effective strategy to implement this using definer's rights?

A) Create separate schemas for each application role, placing objects with different privileges into these schemas. Then, grant the appropriate privileges on each schema to the corresponding application role.
B) Create stored procedures owned by the application, with each stored procedure performing actions within the app. Grant OWNERSHIP on each stored procedure to the application admin. Consumers must then grant USAGE on these procedures to their desired roles.
C) Grant all privileges on all application objects to the 'app_admin' role and rely on the consumer to manage privilege inheritance for other roles.
D) Create views for each application role, granting SELECT privilege on the necessary tables to each view. Then, grant SELECT privilege on the appropriate view to each application role.
E) Create stored procedures owned by the application, with each stored procedure explicitly granting the required privileges to the corresponding role. Consumers must then grant USAGE on these procedures to their desired roles.

5. A financial services company is developing a Snowflake Native App. It needs to securely access external market data via an API and store the processed results in a consumer-provided table. Considering security best practices and the Snowflake Native App Framework limitations, which of the following approaches represents the MOST secure and recommended implementation for this scenario?

A) Utilize a Java UDF with the 'network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer- provided table by using the application role with INSERT privilege granted by consumer.
B) Employ a Snowflake external function, configured with a service account, which invokes an API integration stored in the provider account. The external function returns the data, which is then inserted into a consumer-owned table using a stored procedure and INSERT statements, where the application role has been granted the necessary INSERT privilege.
C) Use a Snowflake external function with an API integration, configured with a service account that has the necessary permissions to access the API. Store the processed data in a consumer-provided table using stored procedures and INSERT statements using the application role.
D) Use a Snowflake external function with an API integration that passes the API key as a parameter. Store the processed data in a consumer-provided table using dynamic SQL.
E) Utilize a Python UDF with the 'external network access' capability to call the external API directly from within the UDF. Store the processed data directly into a consumer-provided table by using the application role. API key is stored in snowflake secret.
