Snowflake SnowPro Specialty - Native Apps 認定 NAS-C01 試験問題:

1. 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) Examine the consumer's ACCOUNT_USAGE views, specifically related to query history and errors that occurred during the installation timeframe.
B) Request the consumer to share their entire Snowflake account metadata with you for debugging purposes.
C) Ask the consumer to manually create all the required roles and grants before attempting the installation again.
D) 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.
E) 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

2. You are designing a Snowflake Native Application that allows consumers to upload data files to a stage within their account, which your application then processes. To enhance security and data governance, you need to implement a callback function that validates the uploaded data before it is processed by your application. The callback function must verify the file format and size. Which of the following options correctly outlines the necessary steps and considerations for implementing this callback function?

A) Set up an AWS Lambda function triggered by S3 events when files are uploaded to the consumer's stage. The Lambda function validates the file format and size and sends a message to a Snowflake queue, which your application then reads.
B) Implement a stored procedure within the application package that receives the file path as input. Register this stored procedure as a callback using 'ALTER APPLICATION ... SET callback_procedure = ..:. The stored procedure performs the validation and raises an error if the file is invalid.
C) Create an external function pointing to an API Gateway endpoint that performs the validation. The application logic calls this external function, passing the file path. The external function then returns a boolean indicating success or failure.
D) Create a UDF that resides within the consumer's account and is called using the 'CALL' command from the provider's application logic. The UDF validates the file properties and returns a boolean indicating success or failure.
E) Define an event table in the provider account and configure a Snowflake Notification to trigger when a new file is uploaded to the consumer's stage. The notification invokes a remote service that validates the file and updates the event table.

3. You are developing a Snowflake Native App that utilizes Streamlit for its user interface. You want to control the app's behavior based on whether it's running in a development environment within your provider account or in a consumer account after installation. Which of the following methods can you use within your 'streamlit.py' to determine the current execution context (Provider vs. Consumer) reliably?

A) Use which is a function specifically designed to check if the app is running in a consumer account.
B) Read an environment variable set during the application installation process by the consumer.
C) Examine the session context function 'CURRENT ACCOUNT()' function and compare it with the provider account identifier, if matches then it is a provider. It is the best method.
D) Query the view. Presence in this view indicates a provider environment.

4. You've developed a Snowflake Native Application and are preparing to release a new version. You want to ensure that if any critical issues are detected after the upgrade, you can quickly revert users back to the previous stable version. Which combination of Snowflake features and best practices should you implement to facilitate a seamless rollback process? Select all that apply.

A) Utilize the 'UNSTAGE VERSION' command to immediately remove the problematic version from all consumer accounts.
B) Before staging the new version, create a new version of the application package with a lower version number that points to the previous stable version's code. Use ALTER APPLICATION' to downgrade users.
C) Keep the previous stable version staged in the application package. If issues arise with the new version, use release directives to direct users back to the previous version by modifying the 'ACTIVATE_AT parameter or using tags.
D) Implement robust logging and monitoring within your application to quickly identify and diagnose any issues after the upgrade.
E) Before staging the new version, create a full backup of all data warehouses used by your application in consumer accounts.

5. You are developing a Snowflake Native App that processes streaming data from a Kafka topic. The app needs to continuously ingest data, perform real-time transformations, and store the results in a Snowflake table within the app's managed database. Which Snowflake feature(s) and approach(es) are BEST suited for implementing this data ingestion and processing pipeline within the Native App?

A) Employ a combination of Snowflake Snowpipe Streaming for data ingestion and Dynamic Tables for continuous, incremental data transformations within the application's managed database.
B) Use Snowflake Pipes to continuously ingest data from the Kafka topic into a staging table and then use stored procedures to periodically transform and load the data into the target table.
C) Implement a custom Kafka consumer within a Java User-Defined Function (UDF) to read data from the Kafka topic and directly insert it into the target table.
D) Use a Snowflake Stream to capture changes in the Kafka topic and then use a Snowflake Task to periodically merge these changes into the target table.
E) Leverage Snowflake Snowpipe Streaming to ingest data directly from the Kafka topic into the target table, combined with Snowflake Tasks to handle any required data transformations.
