Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You have a Snowflake Native Application that utilizes a managed table. After upgrading your application to version 2.0, some users report that they are missing data in the managed table. After investigation, you realize version 2.0 changed the schema of the managed table and also did not properly migrate all the data from old format into new format. Which of the following steps should be taken to address the missing data after upgrading a Snowflake Native Application?

A) Create a new version 2.1 that includes a data migration script to transfer data from the old schema (as it existed in version 1.0) to the new schema in version 2.0. Use release directives to upgrade affected users to version 2.1 after staging.
B) Rollback all users to version 1.0 and then perform the schema migration directly on the consumer's account using custom SQL scripts.
C) Since managed tables are fully managed by Snowflake, contact Snowflake support to initiate a data recovery process in each affected consumer account.
D) Create a new version 2.1. Within version 2.1's setup script, dynamically detect if the application is an upgrade from 1.0 and, if so, execute the data migration script to transfer data from the old schema to the new schema.
E) Manually insert the missing data into the managed table in each consumer's account, contacting affected users to coordinate the data entry.

2. You are designing a Snowflake Native Application that requires managing application roles and permissions. Which of the following best practices should be followed regarding application roles and permissions in a Snowflake Native Application?

A) Define granular application roles with specific permissions, and provide documentation to the consumer on how to grant these roles to their users.
B) Use the 'EXECUTE AS OWNER clause for all stored procedures to avoid granting explicit privileges to the application roles.
C) Avoid using application roles altogether and rely solely on the consumer's existing roles and permissions.
D) Bundle all application logic within a single stored procedure owned by the 'APPLICATION' role.
E) Grant all necessary privileges to the 'APPLICATION' role during setup, as this simplifies permission management for consumers.

3. A Snowflake Native App developer encounters an issue where the application fails to install on a consumer's account due to insufficient privileges. The developer has verified that the necessary privileges are declared in the application. privileges section of the manifest file. However, the installation still fails. What could be the most likely cause of this issue, and how can it be resolved?

A) The consumer account has object level grants conflicting with the required grants. Revoke the object level grants and try again.
B) The consumer's account does not have the SNOWFLAKE.APP_INSTALLER role enabled. Ensure this role is granted to the appropriate user.
C) The privileges were declared in the manifest file, but were not actually granted to the application role in the provider account before creating the version. Grant the declared privileges to the application role using GRANT ON ACCOUNT TO APPLICATION ROLE and create a new version.
D) The consumer's account is not on the same Snowflake region as the provider account. Verify and align the regions.
E) The privileges declared in the manifest file are not supported by the consumer's Snowflake edition. Review and adjust the required privileges.

4. You are developing a Snowflake Native Application that requires robust role-based access control. The application provides data transformation services to consumer accounts. You want to define distinct roles for different levels of access: 'TRANSFORMER_ADMIW (full control), 'TRANSFORMER USER (execute transformations), and 'TRANSFORMER OBSERVER (read-only access to metadata). In the setup script, which SQL statements are the MOST secure and efficient way to achieve this while adhering to Snowflake's recommended practices for application roles?

A)

B)

C)

D)

E)

5. You are developing a Snowflake Native Application that includes a Python UDE This UDF needs to interact with an external API that requires authentication using OAuth 2.0. The application package should securely manage the OAuth credentials without exposing them to the consumer account. How can you securely configure and access the OAuth credentials from within the UDF?

A) Store the OAuth client ID and secret in environment variables within the Snowflake environment for the application.
B) Store the OAuth client ID and secret directly in the UDF code as string literals.
C) Configure an OAuth integration in Snowflake and grant the UDF's role access to it, allowing the UDF to obtain tokens using 'SYSTEM$GET OAUTH TOKEN'.
D) Store the OAuth credentials in a secure external storage (e.g., AWS Secrets Manager) and retrieve them using an external function.
E) Use Snowflake's secret management feature to store the OAuth client ID and secret, and access them from the UDF using 'SYSTEM$GET SECRET.
