Snowflake NAS-C01 Exam Syllabus Topics:

Snowflake SnowPro Specialty - Native Apps Sample Questions:

1. You are developing a Snowflake Native App that allows consumers to configure certain parameters through a setup page. You want to persist these configurations securely. What is the recommended approach to store and retrieve consumer-specific configuration data within a Snowflake Native App?

A) Store the configuration data in a secured view provided by the provider and accessible to the consumer.
B) Store the configuration data as environment variables within the application package.
C) Create a dedicated configuration table within the consumer's Snowflake account using the setup script and use secure UDFs to access it.
D) Store the configuration data in a consumer-specific stage created during app installation.
E) Utilize the 'APPLICATION_SETTINGS' object to store and retrieve configuration parameters. Access these settings within your application logic.

2. You are developing a Snowflake Native Application that provides data enrichment services. You want to implement a phased rollout of a new version to your users. You have three distinct user groups: 'EarlyAdopters', 'StandardUsers', and 'CriticalUsers'. You need to use release directives to manage the upgrade process, ensuring that 'EarlyAdopters' receive the new version first, followed by 'StandardUsers' after a week of monitoring, and finally 'CriticalUsers' two weeks after that. Which of the following approaches is the MOST effective way to achieve this using Snowflake Native App release directives?

A) Use release directives within a single application package to control version availability based on the application role. Create separate roles for each user group and grant them appropriate privileges.
B) Use the SALTER APPLICATION' command with the 'STAGE VERSIONS clause to explicitly assign specific versions to each user group based on their tag values. For example: 'ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'EarlyAdopters';'
C) Create separate application packages for each user group and manage versions independently within each package.
D) Implement a custom upgrade mechanism within your application logic, querying a configuration table to determine which version each user should receive. This table is updated based on a predefined schedule.
E) Use release directives with tag-based versioning. Tag each user account with a tag indicating their user group (e.g., 'user_group = 'EarlyAdopters"). Then, use the 'STAGE_VERSIONS' clause in the 'ALTER APPLICATION' command to associate versions with these tags, specifying a different activation time for each tag. For example: 'ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'EarlyAdopters' ACTIVATE_AT = '2024-01-01 00:00:00'; ALTER APPLICATION my_app STAGE_VERSIONS versioni .1 FOR TAG user_group = 'StandardUserS ACTIVATE_AT = '2024-01-08 00:00:00';'

3. Consider the following setup script intended to install a Snowflake Native Application in test mode. The application relies on a custom role 'APP ROLE' and a secured view 'SECURE VIEW'. Analyze the script and identify which line, if any, contains a critical error that would prevent successful testing:

A)

B)

C)

D)

E)

4. You've developed a Snowflake Native Application. During the installation process in a consumer's account, the installation fails. The error message is vague and doesn't pinpoint the exact cause. What are the MOST effective steps you can take, in order , to diagnose the installation failure and provide the consumer with a resolution? (Select the top 3 steps)

A) Review the event logs generated by the application during the installation process using Snowflake Event Tables. Use the appropriate filtering and querying techniques to narrow down the relevant events.
B) Examine the consumer's ACCOUNT_USAGE views, specifically related to query history and errors that occurred during the installation timeframe.
C) Ask the consumer to manually create all the required roles and grants before attempting the installation again.
D) Leverage the 'SYSTEM$GET PKG INSTALLATION ERRORS function in the provider account to retrieve detailed error messages and debugging information related to the failed installation. Correlate this with the installation version and consumer account I
E) Request the consumer to share their entire Snowflake account metadata with you for debugging purposes.

5. A data analytics company, 'Data Insights Pro', is developing a Snowflake Native Application to provide advanced customer segmentation analysis. They plan to monetize this application through the Snowflake Marketplace. They want to ensure that only a specific set of customer accounts can access and install their application during the initial beta testing phase. Which of the following steps must they perform to achieve this?

A) Create a private listing on the Snowflake Marketplace and share it with the specific customer accounts by explicitly granting access to their Snowflake account identifiers.
B) Publish the application directly to the Snowflake Marketplace without creating a listing, and then share the installation URL with the selected customer accounts.
C) Create a public listing with a very high price to deter unintended installations, then manually adjust the price to zero for beta testers.
D) Create a public listing on the Snowflake Marketplace and rely on Snowflake's built-in usage monitoring to identify the intended customer accounts.
E) Use Snowflake's data sharing feature to share the application package with the customer accounts.
