Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. A Snowflake Native App developer is packaging their application and needs to define the necessary privileges within the application package's manifest file. The application requires 'SELECT' access to a view named 'PROVIDER VIEW' and 'USAGE' on the database 'PROVIDER DB'. Which of the following YAML snippets correctly defines these privileges in the manifest file? (Choose two)

A)

B)

C)

D)

E)

2. A Snowflake Native Application provider is deploying their application in multiple regions (AWS US-East-l and AWS EU-Central-l). The application relies on external functions that interact with a third-party API. The provider wants to optimize for both latency and cost while ensuring high availability. Which of the following strategies represents the MOST effective approach for configuring and deploying these external functions to meet these requirements? Select two.

A) Deploy separate external functions in each region, pointing to API endpoints hosted in the respective regions. Configure each external function with the same security integration to simplify access management.
B) Create a single external function that uses a conditional statement to route requests to different API endpoints based on the Snowflake region where the function is being called. This approach reduces management overhead.
C) Utilize Snowflake's cross-region replication feature to automatically replicate the external functions between regions. This ensures that the functions are always available in both regions.
D) Host the external function code directly within the Snowflake application package and leverage Snowflake's serverless compute to execute the function logic without relying on external APIs.
E) Configure a global load balancer in front of the third-party API endpoints and point all external functions to the load balancer's endpoint. This allows the load balancer to route requests to the closest available API endpoint.

3. You are designing a Snowflake Native Application that allows consumers to upload data files to a stage within their account, which your application then processes. To enhance security and data governance, you need to implement a callback function that validates the uploaded data before it is processed by your application. The callback function must verify the file format and size. Which of the following options correctly outlines the necessary steps and considerations for implementing this callback function?

A) Set up an AWS Lambda function triggered by S3 events when files are uploaded to the consumer's stage. The Lambda function validates the file format and size and sends a message to a Snowflake queue, which your application then reads.
B) Create a UDF that resides within the consumer's account and is called using the 'CALL' command from the provider's application logic. The UDF validates the file properties and returns a boolean indicating success or failure.
C) Define an event table in the provider account and configure a Snowflake Notification to trigger when a new file is uploaded to the consumer's stage. The notification invokes a remote service that validates the file and updates the event table.
D) Create an external function pointing to an API Gateway endpoint that performs the validation. The application logic calls this external function, passing the file path. The external function then returns a boolean indicating success or failure.
E) Implement a stored procedure within the application package that receives the file path as input. Register this stored procedure as a callback using 'ALTER APPLICATION ... SET callback_procedure = ..:. The stored procedure performs the validation and raises an error if the file is invalid.

4. You are managing versions of a Snowflake Native App that persists data to tables within the consumer's account. You want to provide consumers with the ability to rollback to a previous version of the application without losing dat a. Which combination of Snowflake features and practices would best support this requirement?

A) Combine Snowflake's Time Travel feature with automated scripts within your application that identify and restore tables affected by the rollback to the specific point in time when the previous version was active. Provide users with a simplified rollback process.
B) Require consumers to manually back up their data before each application upgrade and provide instructions on how to restore it.
C) Store data version history within the application and reconstruct historical states on demand. This requires complex data modeling and coding.
D) Rely solely on Snowflake's Time Travel feature on the consumer's tables, instructing users to manually restore data to the desired point in time after rolling back the application.
E) Implement a backup and restore mechanism within your application, creating regular snapshots of the consumer's tables and storing them in a secured location. Provide a rollback procedure that restores data from the appropriate snapshot.

5. You are building a Snowflake Native Application that offers a data enrichment service. You want to automate the fulfillment of new customer trials. When a customer installs your application from the Marketplace, you want to automatically provision them with a limited dataset and compute resources for a 30-day trial period. Which of the following Snowflake features and implementation steps are essential for achieving this auto-fulfillment strategy? (Choose two)

A) Use Snowflake's Resource Monitors to automatically limit the credit usage for each trial customer account.
B) Leverage Snowflake's Marketplace Auto-Fulfillment API to automatically create a dedicated share for each customer, granting them access to the limited dataset.
C) Utilize Snowflake's External Functions to call an external auto-fulfillment service (e.g., AWS Lambda) that handles the provisioning logic.
D) Employ Snowflake's Event Tables to capture installation events and trigger a stored procedure within the Native App to provision the trial environment.
E) Implement a webhook endpoint within your Native Application that listens for installation events from the Snowflake Marketplace and triggers the provisioning process.
