Snowflake SnowPro Specialty - Native Apps Sample Questions (Q265-Q270):

NEW QUESTION # 265
You are developing a Snowflake Native Application and need to track changes made to the application code across different versions. You want to leverage Snowflake's built-in capabilities for version control and auditing. Which of the following approaches is the MOST suitable and efficient for achieving this?

A. Use Snowflake's Time Travel feature to query historical versions of application code objects (e.g., stored procedures, UDFs) and compare differences between versions.
B. Use Snowflake's Streams feature to capture changes made to application code objects and store them in a separate change table for auditing.
C. Utilize Snowflake's Information Schema views (e.g., 'INFORMATION_SCHEMA.PROCEDURES, 'INFORMATION SCHEMA.FUNCTIONS) in conjunction with Time Travel to query historical metadata and code definitions.
D. Integrate with an external version control system (e.g., Git) and store application code and deployment scripts in the repository. Use CI/CD pipelines to manage deployments to Snowflake.
E. Manually maintain a change log in a separate Snowflake table, documenting each code modification with associated version numbers and timestamps.

Answer: C

Explanation:
Option E is the most suitable and efficient solution. Combining Snowflake's Information Schema views with Time Travel provides a comprehensive and native way to track changes to application code objects. The Information Schema provides metadata about database objects, and Time Travel allows you to query historical versions of those objects. This approach leverages Snowflake's built-in capabilities without requiring external tools or manual change logging. Options A and B requires extra configuration of the whole process. Option C while feasible, Time Travel has to be enabled on each component, which makes option E superior. Option D is designed for data and not code auditing.

NEW QUESTION # 266
You are building a Snowflake Native Application that provides a data transformation service. You want to allow consumers to configure certain aspects of the transformation pipeline (e.g., the name of the target table, specific transformation logic). What are the recommended approach(es) to allow consumers to customize the application's behavior without directly modifying the application code?

A. Utilize Snowflake's Secure UDFs (User-Defined Functions) and allow consumers to provide their own UDFs as configuration.
B. Implement a configuration table within the application's schema that consumers can update with their desired settings. The application code reads these settings at runtime.
C. Expose parameters within the setup script and stored procedures that consumers can set during application installation or execution.
D. Require consumers to fork the application's repository and modify the SQL code directly.
E. Include default configurations within a file on the external stage, which consumers are expected to download, modify, and then upload back as a different file for the application to load.

Answer: B,C

Explanation:
Options B and D are correct. Exposing parameters in the setup script and stored procedures is a standard way to allow customization during installation and execution. A configuration table provides a flexible way for consumers to manage settings that can be read by the application. Option A is incorrect because forking the repository makes it difficult to manage updates and maintain security. Option C has security implications, as malicious code can be injected through user-defined UDFs. Option E is incorrect as the file download, modify, and upload method are complex for users to configure.

NEW QUESTION # 267
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 '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.
B. Grant 'SELECT on to the application role during the application's setup script. Do not grant 'IMPORTED PRIVILEGES' on the database.
C. Grant 'IMPORTED PRIVILEGES' on to the application role. Grant 'SELECT on to the application role during the application's setup script.
D. Grant USAGE on ' RETAIL_DATX to the application role during the application's setup script. Do not grant 'IMPORTED PRIVILEGES' on the database.
E. 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.

Answer: A

Explanation:
The correct answer is E. IMPORTED PRIVILEGES is required so the application can even see that shared database. USAGE is required on the database before you can select from the table. SELECT is required on the table. This is all done within the application setup script so the consumer does not need to take manual action.

NEW QUESTION # 268
You have a Snowflake Native Application listed on the Marketplace. You need to update the application to add a new feature, which requires changes to both the application code and the database schema within the application package. You want to ensure a seamless upgrade experience for existing consumers, minimizing downtime and data loss. What is the MOST appropriate strategy for deploying this update?

A. Modify the existing application package directly with the updated code and schema. This will automatically update the application for all consumers.
B. Create a new version of the application package with the updated code and schema. Consumers will automatically be upgraded to the new version upon release.
C. Create a new version of the application package. Implement a Snowpark Python stored procedure within the new version that handles schema migrations and data transformations. This procedure should be automatically executed during the upgrade process.
D. Create a new version of the application package. Include a setup script that detects the existing version of the application and performs any necessary schema migrations or data transformations. Announce the new version and instruct consumers to manually upgrade.
E. Create a new version of the application package. Before releasing, use a feature flag system to gradually roll out the new feature to a subset of consumers, monitoring for any issues before a full release.

Answer: D,E

Explanation:
Option B is a strong approach because it uses a setup script to handle schema migrations and ensures compatibility with existing versions. Consumers need to be informed and initiate the upgrade, giving them control. Option D, using feature flags for a gradual rollout, is a best practice for minimizing risk and monitoring the impact of the changes on a smaller user base before a full deployment. Option A is risky because automatic upgrades without proper migration handling can lead to data loss or application errors. Option C, while technically feasible, is less conventional and might not be as easily managed as a setup script for schema changes. Option E is incorrect and impossible; you cannot directly modify an existing application package that has been released. A new version must be created.

NEW QUESTION # 269
You are tasked with automating the installation of a Snowflake Native Application across multiple consumer accounts using the Snowflake Marketplace. The installation process must be idempotent (running the installation script multiple times should not cause errors or unexpected behavior). You have the following requirements: 1. Check if the application is already installed. 2. If not installed, install the application from the Marketplace. 3. Grant specific privileges on the installed application to a role within the consumer account. Which of the following Snowflake Scripting (SnowSQL) snippets BEST implements this idempotent installation process? Assume 'application name', 'application _ package', 'consumer role', and 'marketplace listing url' are pre-defined variables.

Answer: D

Explanation:
Option D provides the best approach. It first checks if the application already exists using 'SHOW APPLICATIONS LIKE 'application_name' and If the application does not exist (count is 0), it proceeds to install the application from the Marketplace using 'CREATE APPLICATION ... FROM MARKETPLACE. The 'GRANT USAGE statement is executed regardless of whether the application was just installed or already existed, making the entire process idempotent. A,B,C do not account for idempotency. E is not idempotent for granting the role.
