Snowflake SnowPro Specialty - Native Apps NAS-C01 Prüfungsfragen mit Lösungen (Q198-Q203):

198. Frage
You are developing a Snowflake Native Application that includes a Python module for data transformation. This module relies on the pandas' and 'requests' libraries. You are using an 'environment.yml' file to manage dependencies. Which of the following 'environment.yml' configurations is the MOST secure and correct way to define these dependencies for your application? Assume you want to install these packages directly from conda-forge channel.

Antwort: D

Begründung:
Option E is the MOST secure and correct. Here's why: Specifying Versions: Explicitly pinning the versions of 'pandas' and requests' (e.g., 'pandas=l .3.5' , ensures consistent behavior across different environments and prevents unexpected issues caused by updates to these libraries. This greatly enhances the reproducibility and stability of your application. Using conda-forge Channel: Specifying 'conda-forge' as the channel is generally recommended for Snowflake Native Apps as it provides a broader selection of packages and often includes versions compatible with the Snowflake environment. It also tends to have more up-to-date packages. Avoiding 'pip': While 'pip' can be used, it's generally better to use 'conda' for managing dependencies in a 'environment.ymr file as it can handle non-Python dependencies as well and integrates better with Conda environments. Option A is less desirable because it relies on 'pip' without a specified channel, which can lead to inconsistencies and potential security vulnerabilities. Option B is better than A because it uses conda-forge but lacks version pinning. Option C uses 'defaults' channel which is less preferable to conda-forge and lacks version pinning. Option D unnecessarily mixes pip with the Conda package manager.

199. Frage
You are developing a Snowflake Native Application and want to implement a usage-based pricing model. Your application writes usage data to a table 'APPLICATION USAGE' in the provider account. You need to create a listing on the Snowflake Marketplace that charges customers based on the number of processed records. Which of the following steps are crucial to correctly setting up the pricing plan within the listing, ensuring that usage data is properly captured and reflected in the customer's bill?

A. Define a usage-based price metric within the listing that directly queries the 'APPLICATION_USAGE table in the consumer account using a secure view.
B. Establish a Data Exchange between the provider and consumer accounts, sharing the 'APPLICATION_USAGE' table directly. The listing then references this Data Exchange for pricing.
C. Define a resource monitor on the provider account that tracks resource consumption of the application, and use this as the basis for pricing. This requires no customer interaction.
D. Configure a usage-based price metric within the listing, pointing it to a secure view created on top of the 'APPLICATION_USAGE' table, explicitly granted to the 'snowflake' account. The secure view should aggregate usage data.
E. Create a stored procedure in the provider account that aggregates the usage data in 'APPLICATION USAGE' , and then configure the listing to execute this stored procedure at regular intervals to calculate charges.

Antwort: D

Begründung:
The correct answer is C. A usage-based price metric must point to a secure view that aggregates usage data from the 'APPLICATION_USAGE table. The secure view ensures that data access is controlled and that consumers only see the aggregated usage information required for billing. Option A is partially correct, but misses explicitly granting access to snowflake account, vital for pricing. Other options are incorrect because they either expose raw data (D), rely on procedures which are hard to manage within the marketplace (B), try to query consumer data which is impossible using provider side secure view (A) or irrelevant to usage based pricing (E).

200. Frage
A data science team within your organization is developing a Snowflake Native App that needs to access and process customer data stored in a Snowflake database. The app must only access data for customers residing in the 'USA' region. The team has created a custom role 'APP ROLE for the app to use. Which of the following is the MOST secure and efficient way to grant the app the necessary permissions to read the filtered data? Assume a secure view approach is preferred over direct table access.

A. Grant the SAPP ROLE the 'OWNERSHIP' privilege on the base customer data table and implement data filtering logic within the app itself.
B. Grant the 'APP_ROLE the 'USAGE privilege on the database and schema containing the customer data table. Data filtering should still be handled by the app.
C. Create a secure view that filters customer data to include only customers in the 'USA' region and grant the SAPP ROLE the 'SELECT privilege on the secure view.
D. Create a standard view (non-secure) that filters customer data to include only customers in the 'USA' region and grant the 'APP_ROLE the 'SELECT' privilege on this view.
E. Grant the 'APP_ROLE the 'SELECT privilege on the base customer data table and rely on row-level security policies defined on that table.

Antwort: C

Begründung:
Secure views offer a crucial security advantage: they hide the underlying table structure and any associated metadata from the app, only exposing the filtered data. Row-level security (RLS) can work (A), but secure views provide an extra layer of abstraction and security, hiding the existence of other rows. Granting ownership (C) is highly insecure and unnecessary. Non-secure views (D) do not offer the security benefits required for sensitive data. USAGE privilege alone (E) doesn't grant any data access without SELECT.

201. Frage
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. 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.
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. The consumer is responsible for implementing observability and telemetry. The application developer cannot implement observability features that function within the consumer's account.
D. 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.
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.

Antwort: B

Begründung:
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.

202. Frage
You are developing a Snowflake Native App. Your app needs to interact with the consumer's Snowflake account to retrieve dat a. You want to ensure that your app only has access to the necessary data and that the consumer can control the data access. Which of the following methods is the MOST secure and recommended way to achieve this?

A. Create a shared secret between the provider and consumer accounts and use this secret to authenticate API calls for data access.
B. Create a service account within the consumer's Snowflake account and grant the necessary privileges to this account.
C. Use a Snowflake account administrator role to execute all queries within the app.
D. Utilize Snowflake's secure data sharing feature combined with granular access control policies (row access policies, masking policies) within the provider's app, granting access to specific views or tables.
E. Expose an API endpoint within the consumer's account that grants access to the data without any restriction.

Antwort: D

Begründung:
Snowflake's secure data sharing feature, coupled with granular access control policies, provides the MOST secure and controlled way to access data within a consumer's Snowflake account. This approach allows the provider to define which data the app can access and the consumer to control the access through policies.
