問題 #216
A provider is testing their Snowflake Native Application in a consumer environment. The application includes a Streamlit app that displays data from a table provisioned in the consumer account. The consumer reports that the Streamlit app is displaying an errorrelated to accessing the table. The 'streamlit.secretS dictionary is used to store the database connection details. The application role app_role' is designed to have access to the table. Which of the following could be potential causes of the problem, assuming the connection details are valid?
答案：A,C,D
解題說明：
Options A, B, and C are correct. For the Streamlit app to function correctly, the 'app_role' must have 'USAGE on the database, 'SELECT' on the table, and the Streamlit app must be correctly configured to assume the 'app_role' when executing queries. Option D is incorrect because the table is provisioned in the consumer environment, so sharing with the provider is not applicable. Option E is incorrect because streamlit.secrets' is a dictionary within the app, not related to file permissions.
問題 #217
You are developing a Snowflake Native Application and want to implement comprehensive cost monitoring for your application's resource consumption within a consumer's Snowflake account. Which of the following approaches provide the MOST effective and granular cost visibility for both you (as the provider) and your consumers?
答案：B
解題說明：
Option E provides the most granular and effective cost monitoring. Using Snowflake's query history from the ACCOUNT USAGE schema allows access to detailed resource consumption data. Combining this with custom tagging (e.g., using 'ALTER WAREHOUSE ... SET TAG allows associating specific queries and resources with your application and its features. This enables creating detailed cost breakdowns for consumers, showing exactly how much each feature is costing them. While B and C are useful, they require more manual effort and custom coding for aggregation. A and D lack application-specific detail. This allows for better chargeback, cost control and optimization.
問題 #218
You are creating a Snowflake Native Application that will be distributed to consumer accounts. As part of the installation process, you need to ensure that a specific database role, 'DATA READER, is created in the consumer account and granted 'SELECT' privileges on a specific table in the consumer's shared dat a. Which of the following code snippets, when placed within the application's setup script (install.sql), will correctly achieve this, assuming the application is granted 'CREATE DATABASE ROLE?
答案：D
解題說明：
Option D correctly creates the database role, grants the necessary privileges, and associates it with the application. Here's a breakdown: 'CREATE OR REPLACE DATABASE ROLE DATA_READER;': creates or replaces the database role 'DATA_READER in the consumer account. 'GRANT SELECT ON TABLE CONSUMER DB.PUBLIC.MY TABLE TO DATABASE ROLE DATA READER;': Grants the 'SELECT privilege on the specified table to the 'DATA_READER role. It assumes that already exists in the consumer account through data sharing or some other mechanism. 'GRANT DATABASE ROLE DATA READER TO APPLICATION ROLE app_public;': This grants the database role to the application role, making the database role available to the application via the 'app_public' application role. 'GRANT APPLICATION ROLE app_public TO APPLICATION This is essential. This makes sure the application has the privileges from the application role granted. Without this, the database role is effectively useless to the application. In the consumer account, this means it will be able to use application. It should have an application object representing installed app in Consumer Account. Option A is incorrect because granting to 'SHARE is not the appropriate way to grant the role to the application. This is meant for granting to other accounts. Option B is incorrect because application will not be able to use app_public if not granted. Option C is incorrect because you need to assign database role to application role so it can be properly managed at the application level. You also need to grant the application role to the applicatiom Option E is incorrect because you should not grant the application role to SHARE; it will provide access to any accounts using the share, and can lead to over-privileged access.
問題 #219
You are developing a Snowflake Native Application that processes sensitive customer dat a. The application needs to comply with data residency requirements in both the EU (Frankfurt) and the US (Virginia). You have decided to use Snowflake's multi-region capabilities for failover and regulatory compliance. You plan to install the application in both regions. What considerations are MOST critical when designing your application's installation process to ensure data locality and business continuity?
答案：B,D
解題說明：
Options A and C are the most critical. Option A ensures the application can connect to the correct data stores in each region, respecting data locality. Option C leverages Snowflake's replication features to ensure both the application code and the data products it relies on are available in both regions for business continuity. B is something good to have but its not the MOST critical, D is also good but it is not the installation process , E is wrong since the code should be first priority for replication
問題 #220
A Snowflake Native App developer is designing an application that requires persisting a large volume of intermediate data during a complex data transformation process. This data is only needed during the execution of the app and can be discarded afterward. Which of the following storage options within the Snowflake Native App Framework would be MOST suitable for this purpose, considering both performance and cost-effectiveness?
答案：A
解題說明：
Volatile tables are the most suitable option because they are designed for storing temporary data that is only needed for the duration of the session. They provide good performance and are automatically dropped when the session ends, ensuring efficient use of storage resources and preventing data leakage. Transient tables are retained until explicitly dropped, while permanent tables incur ongoing storage costs. User's temporary stage access is generally restricted. External stages add complexity and are generally used for data sharing, not temporary storage.
