Snowflake NAS-C01 Exam Syllabus Topics:

Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are designing a setup script for a Snowflake Native Application. This script needs to perform the following actions: 1. Create a secure view that exposes a subset of data from a table owned by the provider account. 2. Grant 'SELECT privilege on this secure view to a specific role within the consumer account, but ONLY if that role already exists in the consumer account. 3. Create a UDF in the provider account which calls external function. This UDF needs access to a secret stored in a Snowflake secret object. Which of the following code snippets BEST implements these requirements, ensuring both security and proper privilege management?

A)

B)

C)

D)

E)

2. 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.

3. You've developed a Snowflake Native Application and are preparing to release a new version. You want to ensure that if any critical issues are detected after the upgrade, you can quickly revert users back to the previous stable version. Which combination of Snowflake features and best practices should you implement to facilitate a seamless rollback process? Select all that apply.

A) Implement robust logging and monitoring within your application to quickly identify and diagnose any issues after the upgrade.
B) Keep the previous stable version staged in the application package. If issues arise with the new version, use release directives to direct users back to the previous version by modifying the 'ACTIVATE_AT parameter or using tags.
C) Before staging the new version, create a full backup of all data warehouses used by your application in consumer accounts.
D) Before staging the new version, create a new version of the application package with a lower version number that points to the previous stable version's code. Use ALTER APPLICATION' to downgrade users.
E) Utilize the 'UNSTAGE VERSION' command to immediately remove the problematic version from all consumer accounts.

4. You are packaging a Snowflake Native App for distribution. Which of the following artifacts are essential components of the application bundle that must be included?

A) Compiled Java JAR files if the app includes Java UDFs.
B) The application's source code (e.g., SQL scripts, Python files).
C) The manifest file (snowflake.yml).
D) The 'setup.sql file containing the application's initialization logic.
E) Binary executables compiled for a specific operating system.

5. A data analytics company is developing a Snowflake Native App that allows customers to enrich their existing Snowflake data with external, proprietary datasets. The application requires READ access to customer tables and the ability to store processed results within the application's managed database. Which combination of Snowflake Native App Framework privileges and features is MOST appropriate to achieve this functionality?

A) The application package grants OWNERSHIP privilege on customer tables to the application. Use standard INSERT statements within stored procedures to write enriched data into the application's managed database.
B) The application's manifest includes REQUESTED PRIVILEGES = [ 'USAGE ON DATABASE', 'READ ON TABLE' ]. Use stored procedures executing with caller's rights to access customer tables and standard INSERT statements to write to the managed database.
C) Use an API Integration to securely access the customer's data and a Stored Procedure to write the enriched data into application's stage.
D) The application's manifest includes REQUESTED PRIVILEGES = [ 'READ' l. Use stored procedures executing with definer's rights to access customer tables and external functions to write to the managed database.
E) The application's manifest includes REQUESTED PRIVILEGES = [ 'READ ON DATABASE', 'READ ON TABLE' l. Use stored procedures executing with definer's rights to access customer tables through a secure view, and standard INSERT statements to write to the managed database.
