NEW QUESTION # 207
You are developing a Snowflake Native App that requires accessing sensitive user data within the consumer's account. To ensure data privacy and security, you need to implement appropriate access controls. Which of the following approaches is the MOST secure and recommended way to grant your app access to this data, assuming the data is stored in a table named 'user_data' ?
Answer: C
Explanation:
The most secure approach is to use a secure view. This allows you to control which rows and columns the application can access. Granting 'SELECT directly to the application role is generally discouraged as it exposes the entire table. Using 'EXECUTE AS CALLER has security implications and might not be desirable. Creating custom roles in the consumer account adds complexity to the application deployment.
NEW QUESTION # 208
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:
Answer: E
Explanation:
While the code seems correct at first glance, the critical missing piece is the 'GRANT USAGE ON SCHEMA privilege. Without this, the 'APP_ROLE won't be able to access objects within the schema containing the 'SECURE_VIEW'. The rest are valid commands.
NEW QUESTION # 209
Consider the following Java UDF code snippet intended for use in a Snowflake Native Application. The UDF is designed to retrieve data from an external REST API. The code throws a 'java.net.SocketTimeoutException' intermittently when the API takes longer than expected to respond. How can you best handle this exception within the UDF to provide a more informative error message to the consumer and prevent the entire application from failing?
Answer: B
Explanation:
Option C is the best approach. Throwing a 'SnowflakeSQLException' allows you to provide a structured error message to the consumer with a custom error code CAPI_TIMEOUT) and a user-friendly message. It also includes the original exception for debugging purposes. Option A throws a generic 'RuntimeException' which is not specific to Snowflake and doesn't provide a clear error code. Option B only prints the error to standard error, which may not be captured or easily accessible within Snowflake. Option D returns a string which may not be the expected return type of the UDF and doesn't provide a structured error. Option E only logs the exception to an external service but the UDF needs to handle the error and return the correct snowflake error.
NEW QUESTION # 210
A provider is developing a Snowflake Native App. They have created a database named 'app_db' using 'CREATE DATABASE app_db WITH MANAGED ACCESS;'. Subsequently, they need to create a schema within this database and grant specific privileges on the schema's objects to a role 'app_admin' . Which of the following SQL statements are valid and necessary to set this up securely and effectively?
Answer: A,C
Explanation:
Since the database 'app_db' was created with 'MANAGED ACCESS, simply creating the schema using 'CREATE SCHEMA app_db.internal_schema;' inherits the managed access properties. Granting 'USAGES is necessary to allow the role to access objects within the schema. Granting ownership is typically not required and could unnecessarily elevate privileges. Option B, while valid syntax, will result in an error, the MANAGED ACCESS is already inherited from the DATABASE and therefore redudnant. Option D is too permissive. Option E, using all privileges, is not best security practice, rather only the specific USAGE is needed in this scenario.
NEW QUESTION # 211
Consider the following scenario: You're developing a Snowflake Native Application that requires both data loading and complex analytical queries. You plan to use separate warehouses to optimize performance and manage resources effectively. Given the requirements, which of the following warehouse configurations is the MOST appropriate?
Answer: D
Explanation:
Option D provides the best configuration. Using separate warehouses allows you to optimize each workload independently. SMALL' is often sufficient for data loading tasks, while a 'LARGE warehouse provides better performance for analytical queries. Setting 'MAX CONCURRENCY LEVELS on the analytical warehouse allows for better handling of multiple concurrent users or queries. Option A does not isolate workloads and can lead to performance bottlenecks. Option B only addresses size but not concurrency. Option C focuses only on auto- suspend, ignoring other warehouse parameters for optimizing workload.Option E is partially correct, because Initially_Suspended is good idea but does not help in complete warehouse setting.
