Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native Application and want to implement robust observability and telemetry. Which of the following approaches will enable you to effectively monitor the application's performance, identify errors, and collect usage metrics within the consumer's account?

A) Rely solely on Snowflake's built-in query history and resource monitoring features in the consumer's account, as these automatically capture all application activity.
B) Utilize to write log data to a secure table within the application and leverage views granted to the consumer to expose relevant metrics and error information. Ensure appropriate roles have access to the views.
C) Implement custom logging using 'SYSTEM$LOG' and store application logs in a separate table within the application's container. Configure grants to allow the application developer to access these logs.
D) The consumer is responsible for implementing observability and telemetry. The application developer cannot implement observability features that function within the consumer's account.
E) Directly access the consumer's system tables (e.g., 'SNOWFLAKE.ACCOUNT USAGE.QUERY HISTORY) to extract application-related metrics based on query identifiers generated by the application.

2. 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)

3. You've installed a Snowflake Native Application in your consumer account. You are trying to establish observability and telemetry to monitor its performance and identify potential issues. However, you notice that you only have limited visibility into the application's internal operations. Which actions should you take to enhance observability, assuming the provider has implemented appropriate mechanisms?

A) Subscribe to events shared by the application provider through Snowflake's event sharing mechanism, if the provider has enabled it. Leverage shared views exposing specific metrics.
B) Use Snowflake's Query Profile to analyze the execution plans of queries initiated by the application.
C) Request the application provider to grant you direct access to the application's internal logs and system tables.
D) Enable detailed logging in your consumer account to capture all SQL statements executed by the application, then analyze these logs.
E) Examine the APPLICATION USAGE view in the SNOWFLAKE database to track resource consumption and query performance of the application's components.

4. You are developing a Snowflake Native App that provides data enrichment services to consumer accounts. The app requires access to both a secure internal API (accessible only within your provider account) and the consumer's data warehouse. Which of the following components and configurations are necessary to facilitate this access while adhering to Snowflake's security best practices?

A) A UDF (User-Defined Function) defined in the application package that invokes the secure internal API using a secured API integration, and grants OWNERSHIP on it to the APPLICATION role. The consumer grants USAGE on their database to the application role.
B) A Python UDF defined in the application package that connects to the secure internal API using a secured API integration with allowed egress network policy that only allows connections from the app's deployment region. The consumer shares their database with the provider account through a data sharing arrangement.
C) A Stored Procedure defined in the application package that invokes the secure internal API via network rule with outbound traffic allowed only for the app, and utilizes a reader account to securely query the consumer s data with the use of SNOWFLAKE.CORE.AUTHZ.PASS_PRIVILEGES().
D) A Java UDF defined in the application package uses JDBC connection to access a secure internal API endpoint. The consumer grants USAGE privilege to the application on their schemas.
E) A Snowpark function that leverages the SNOWFLAKCORE.AUTHZ.PASS PRIVILEGES() function with the application role executing the code. The app requires the consumer to create a shared secret to access their API.

5. You are building a Snowflake Native Application that includes a stored procedure to perform data transformation. This stored procedure needs to access external data sources using a secure API. Which of the following methods provides the MOST secure and recommended approach for managing API credentials within the Snowflake Native Application context?

A) Store the API credentials directly within the stored procedure code as encrypted strings. Decrypt them at runtime using a key stored in a separate table.
B) Hardcode the API credentials directly within the stored procedure code. This is the simplest approach for development and testing.
C) Use Snowflake's Secret object to securely store the API credentials. Access the Secret within the stored procedure using function.
D) Use the consumer's account's environment variables to store API credentials. The application retrieves credentials from there.
E) Store the API credentials in a configuration file included within the application package. Read the credentials from this file within the stored procedure.
