Snowflake SnowPro Specialty - Native Apps Sample Questions (Q59-Q64):

NEW QUESTION # 59
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. 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.
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. 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.

Answer: B

Explanation:
Option C is the most effective approach. Using 'SYSTEM$LOG' allows for structured logging within the application. Storing the logs in a secure table within the application container keeps the data isolated and controlled. Creating views and granting access to specific roles on the consumer side allows the application to expose relevant metrics and error information without granting direct access to the underlying log data. Options A, D, and E are incorrect because they do not provide a comprehensive and controlled observability solution managed by the application developer. Option B is incorrect because the application developer cannot directly access data created in the consumer's account after installation.

NEW QUESTION # 60
You are developing a Snowflake Native App that needs to be configurable by the consumer during installation. You define parameters in the 'manifest.ymr file. During application installation, the consumer provides values for these parameters. How can you access these parameter values within your application's setup script ('setup.sql')?

A. You must use the 'GET_DDL' function to retrieve the parameter values from the application object definition. The returned DDL string will contain the parameter values, which you need to parse.
B. Parameter values are stored in a dedicated table automatically created by Snowflake during application installation. You can query this table using standard SQL to retrieve the parameter values.
C. Parameter values are automatically available as global variables within the 'setup.sqr script. You can reference them directly by their name as defined in the 'manifest.yml'.
D. Use the ' SYSTEM$GET PARAMETER function within the 'setup.sqr script, passing the parameter name as an argument. This function retrieves the current value of the specified parameter for the application.
E. Parameter values are passed as arguments to the 'setup.sqr script. You need to define input parameters in the script declaration and then access them by their position or name.

Answer: D

Explanation:
The correct answer is D. The 'SYSTEM$GET_PARAMETER function is the designated way to access the parameter values specified by the consumer during installation from within the application's setup script. This function allows you to dynamically configure the application based on the consumer's input.

NEW QUESTION # 61
You are building a Snowflake Native App that needs to store configuration settings specific to each consumer account. These settings will influence the behavior of the application. Which of the following methods is the MOST secure and recommended approach for managing these configuration settings within the Snowflake Native App Framework?

A. Use external configuration files stored in an Amazon S3 bucket and accessed via external functions. This provides flexibility and scalability.
B. Store the configuration settings in a public database table within the application's share. This makes the settings easily accessible to all consumers.
C. Store the configuration settings directly within the application's code. This allows for easy access and modification during development.
D. Utilize parameters defined in the 'setup.sql' script and accessible via SQL commands like 'SYSTEM$GET APP PARAMETER. This allows consumers to configure the application during installation.
E. Hardcode the configuration settings directly into the manifest file as environment variables.

Answer: D

NEW QUESTION # 62
You are developing a Snowflake Native Application that utilizes Snowpark Container Services (SPCS) to run a machine learning model within the customer's Snowflake environment. The application requires access to data stored in a secure stage within the customer's account. Considering security best practices and the limitations of SPCS in Native Apps, what is the most secure and recommended approach to grant the container access to the customer's data stage?

A. Packaging the data within the application package during the build process. This eliminates the need for runtime access to the customer's data stage.
B. Creating a Snowflake Stored Procedure with 'EXECUTE AS CALLER rights and granting the application's service account execute access to the stored procedure. The stored procedure reads data from the secure stage and returns it to the container via a secure data sharing mechanism.
C. Utilizing a Snowflake external function that proxies the data access request to an external API gateway managed by the provider, which then fetches the data from the secure stage. This keeps the access credentials out of the customer's environment completely.
D. Granting the application's service account the 'READ privilege directly on the secure stage. This ensures the container can directly access the data.
E. Creating a Snowflake UDF that reads data from the secure stage and exposes it through a secure view, which the container accesses using the application's service account.

Answer: B,E

Explanation:
Options B and E are the most secure and recommended approaches. Option B uses a UDF and secure view to abstract the data access, limiting the container's direct access to the secure stage and leveraging Snowflake's security features. Option E uses a Stored Procedure executed as the caller to access the data on behalf of the application's service account. This allows the service account access to the stored procedure itself, but the access to the underlying stage is controlled by the owner of the stored procedure and not the application. Options A is less secure as it directly grants access to the stage. Option C, while secure in principle, overcomplicates the data access pattern and relies on external infrastructure. Option D is not feasible for large datasets and is generally not a scalable solution.

NEW QUESTION # 63
Consider the following Snowflake Native Application design scenario: You are building a data enrichment application. This application requires a consumer to grant usage on a specific database in their account. The application will then use a user-defined function (UDF) to access and enrich the dat a. To minimize the risk of data exposure and adhere to best practices, which of the following approaches should you take when designing the UDF?

A. Create the UDF with the 'VOLATILE' keyword to ensure it only runs when explicitly called, limiting the potential for unintended data access.
B. Create the UDF with the EXTERNAL_ACCESS' keyword to explicitly allow it to access data outside of the application package.
C. Create the UDF without any special keywords, relying solely on the consumer's permissions to control data access.
D. Create the UDF with the 'SECURE keyword and implement granular access control within the UDF code, restricting access based on the application role.
E. Create the UDF with the 'IMMUTABLE keyword to prevent any data modification within the consumer's database.

Answer: D

Explanation:
The 'SECURE keyword (Option B) is crucial for protecting data within a Snowflake Native Application. By creating a secure UDF, you can ensure that the UDF's code is protected from unauthorized inspection and modification. Furthermore, implementing granular access control within the UDF allows you to restrict data access based on the application's role, minimizing the risk of data exposure and adhering to best practices. 'VOLATILE, 'IMMUTABLE , and ' EXTERNAL_ACCESS' are irrelevant in this context. Not using any special keyword will not protect your data.
