Snowflake SnowPro Specialty - Native Apps Sample Questions (Q40-Q45):

NEW QUESTION # 40
You are creating a Snowflake Native App using the Native Apps Framework. Your application needs to perform a task that must execute on a regular schedule (e.g., daily data refresh). Which Snowflake feature(s) can you leverage to achieve this, and what considerations are important when using them within the Native App context?

A. Snowflake Streams should be used to track data changes and trigger the refresh process. The Stream must be defined in the application package, and a separate task can be configured to consume the stream data.
B. Snowflake Pipes are the preferred method for scheduled data ingestion within Native Apps, as they are designed for continuous data loading from external sources.
C. You should implement an external scheduler (e.g., AWS Lambda, Azure Functions) that triggers a Snowflake Stored Procedure via the Snowflake API. The Stored Procedure should be owned by the APPLICATION role.
D. Use Snowflake Alerts with a cron schedule to trigger a stored procedure owned by the APPLICATION role. The procedure executes any scheduled task.
E. Snowflake Tasks can be used directly within the Native App, but you must ensure the task definition is part of the application package and the task is resumed upon installation in the consumer account. The task must use the APPLICATION role.

Answer: D,E

Explanation:
Snowflake Tasks provide a native scheduling mechanism within Snowflake. When using them in a Native App, the task definition must be included in the application package. The task MUST be owned by the APPLICATION role to ensure proper security and access control. External schedulers introduce unnecessary complexity and dependency. Streams are for change data capture, not direct scheduling. Alerts provide a lightweight scheduling mechanism for smaller tasks. Pipes are specifically for continuous data loading from external sources.

NEW QUESTION # 41
A consumer installs a Snowflake Native App that collects usage statistics. The app uses an internal stage to store temporary data before aggregating it and sending it to the provider. The consumer notices that the internal stage is consuming a significant amount of storage and wants to understand if they are being charged for this storage. As a consumer, what level of visibility and control do you have over the storage costs associated with the internal stage created and managed by the installed Snowflake Native App?

A. The consumer has full visibility into the stage's storage consumption through the Snowflake web interface and can directly manage the stage's lifecycle to control costs.
B. The consumer has no visibility into the stage's storage consumption or control over its lifecycle. All costs are borne by the application provider.
C. The consumer is billed for the storage used by the internal stage, but they have no direct visibility into its usage or control over its lifecycle. The provider manages the stage's lifecycle.
D. The consumer can only see the stage's metadata but cannot see the data residing in it.
E. The consumer can view the overall storage consumption of the application but cannot differentiate between the internal stage and other data stored by the application.

Answer: C

Explanation:
As a consumer, you are billed for the storage used by the application's internal stage. However, you have no direct visibility into the stage's usage or control over its lifecycle. The application provider manages the stage and data within. The consumer is billed for the storage within their account that the application uses. They are unaware of the data details within the application but still responsible for charges.

NEW QUESTION # 42
You are developing a Snowflake Native Application that uses Snowpark Container Services. Your application consists of multiple containerized services that require varying levels of computational resources. You want to optimize resource utilization and minimize costs by using a single Compute Pool for all services, while ensuring that each service has guaranteed access to resources. Which of the following strategies and SQL commands (or configurations) can be used to achieve this?

A. Create a resource monitor and assign it to the COMPUTE POOL to manage cost. Resource monitors cannot be used to granular control the compute pool usage for native applications.
B. Use a single Compute Pool and rely on the container orchestration system to dynamically allocate resources among the services. Monitor utilization and adjust the Compute Pool size as needed. No SQL commands are needed.
C. Create a single Compute Pool and configure resource quotas for each service using container orchestration-specific configurations (e.g., Kubernetes resource quotas). While not directly managed via SQL, proper configuration of the container orchestrator is required.
D. Use a single Compute Pool, create separate user-defined functions (UDFs) for each service and control resource allocation using the 'RESOURCE MONITOR parameter for each UDF.
E. Create separate Compute Pools for each service, sizing each pool according to the service's peak resource requirements.

Answer: B,C

Explanation:
Option B is valid because the underlying container orchestration system dynamically allocates resources. Option C is also valid because resources can be configured in container orchestration systems to achieve resource guarantees for each service. Creating separate compute pools may be costly and inefficient in terms of resource management. Resource Monitors are for cost control not fine-grained service-level resource management. It provides control to monitor cost. The correct configuration of the container orchestrator is critical to achieve desired outcomes.

NEW QUESTION # 43
You are developing a Snowflake Native Application that requires access to a specific stage in the consumer's account to read configuration files. The application needs to be able to create temporary files in the same stage during its execution. Which set of privileges needs to be granted on the stage to the application's service account, and how do you grant them?

A. Grant READ and WRITE privileges on the stage using Snowsight, and ensure the application uses a service integration with appropriate permissions.
B. Grant USAGE on the database, USAGE on the schema containing the stage, and READ and WRITE privileges on the stage to the application's service account using a combination of SQL commands and Snowsight.
C. Grant USAGE and READ privileges on the stage and CREATE FILE on the schema containing the stage to the application's service account using Snowsight.
D. Grant OWNERSHIP on the stage to the application's service account. No other privileges are required.
E. Grant READ and WRITE privileges on the stage to the application's service account using the 'GRANT USAGE ON INTEGRATION TO APPLICATION command.

Answer: B

Explanation:
To allow the application to read configuration files and create temporary files in the stage, it needs the following privileges: USAGE on the database, USAGE on the schema containing the stage, READ privilege to read existing files, and WRITE privilege to create new files. These can be granted through a combination of SQL commands (for database and schema USAGE) and Snowsight (for stage READ and WRITE). Option D correctly specifies all the necessary privileges and the method for granting them. Ownership (Option E) is not necessary and would grant excessive permissions. USAGE on integration is specific to external functions/APl integrations, not stage access directly.

NEW QUESTION # 44
A Snowflake Native App developer is building an application package that contains multiple versions. They want to ensure that a consumer upgrading from version 1.0 to version 2.0 MUST execute a specific set of SQL scripts as part of the upgrade process to migrate existing application dat a. Which Snowflake Native App feature should they leverage to achieve this?

A. Application Role-Based Access Control (RBAC)
B. A version change handler defined within the application package.
C. Snowflake Pipes to load and transform the existing data.
D. Snowflake Streams and Tasks to monitor the application version and trigger the migration scripts automatically.
E. A post-install script defined in the setup script.

Answer: B

Explanation:
Option C is the correct approach. A version change handler is a dedicated script that runs automatically when a consumer upgrades or downgrades the application. This handler can contain the necessary SQL scripts to migrate data, update schemas, or perform any other actions required during the version transition. Option B executes only during initial installation, not during upgrades. Option A, RBAC, manages permissions but doesn't execute scripts. Option D, Streams and Tasks, could be used, but it's more complex than a version change handler. Option E is used for continuous data loading.
