질문 # 304
A software company, 'Datalnsights', is developing a Snowflake Native Application that requires restricted access to a source data table in the consumer's account. Datalnsights wants to ensure that only the application can access the data, and the consumer cannot directly query it. What is the MOST secure and recommended approach Datalnsights should use within their application package to grant access?

A. Creating a secure view on top of the source data table and granting 'SELECT privilege to the application role on the view.
B. Granting 'SELECT privilege directly on the source data table to the application role.
C. Exposing the table directly through the application's setup script using 'GRANT SELECT ON TABLE TO APPLICATION ROLE app_role' .
D. Granting the ' USAGE privilege on the database and schema containing the source data table directly to the application role.
E. Using a secure UDF within the application to access the source data table, ensuring data masking and redaction, with only the UDF being granted SELECT privileges on the table.

정답：E

설명：
Using a secure UDF is the recommended approach. By encapsulating the data access within a secure UDF, you can control precisely how data is accessed and potentially mask sensitive information. Options A, B and E grants direct access which contradicts the requirement for data restriction. While a secure view (C) adds a layer of indirection, a UDF provides greater flexibility and control over the data access logic and potential redaction.

질문 # 305
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?

정답：B

설명：
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.

질문 # 306
You are designing a setup script for a Snowflake Native Application. This script needs to perform the following actions: 1. Create a secure view that exposes a subset of data from a table owned by the provider account. 2. Grant 'SELECT privilege on this secure view to a specific role within the consumer account, but ONLY if that role already exists in the consumer account. 3. Create a UDF in the provider account which calls external function. This UDF needs access to a secret stored in a Snowflake secret object. Which of the following code snippets BEST implements these requirements, ensuring both security and proper privilege management?

정답：E

설명：
Option B correctly implements all requirements. It uses a 'BEGIN...ENDS block with an statement to check for the existence of the 'consumer_role' before granting the privilege. This prevents errors if the role doesn't exist. Also it creates a UDF which utilizes Snowflake Secret object to fetch secretes. Using Javascript code inside UDF directly to fetch secrets is not allowed. Options A, C and D do not check for role existence and doesn't configure Snowflake secret object

질문 # 307
A consumer reports that they are unable to query a table 'SECURE DATA' provided by your Snowflake Native Application, even though they have been granted the necessary 'SELECT' privilege on the application database role. When troubleshooting, you observe the following:

A. The table 'SECURE_DATX is a secure view referencing other tables, and the consumer lacks the 'IMPORTED PRIVILEGES' grant on the application package or appropriate database roles to access the underlying objects. Grant the 'IMPORTED PRIVILEGES' on the application package.
B. The consumer is attempting to query the table using a warehouse that is too small to handle the data volume. Advise the consumer to increase their warehouse size.
C. The table 'SECURE DATA has row access policies applied that restrict access based on the consumer's user attributes. Verify the policies and adjust them if necessary.
D. The consumer's query is attempting to access columns that are masked using dynamic data masking policies, and the consumer's role lacks the 'APPLY MASKING POLICY privilege. Revoke the masking policy.
E. The table 'SECURE_DATA' is protected by a data governance firewall rule in the provider account, blocking the consumer from accessing data that violates the rules set within the firewall. Review and update the firewall rules to allow this specific query pattern from the consumer.

정답：A,C,E

설명：
Options A, C and E are correct. Row access policies, data governance firewall and secure views (especially with masking policies) are common causes of access restrictions. If the consumer is missing permissions, or data governance firewalls prevent access, the query will fail even with SELECT privileges on the table. Option B is incorrect as this would cause a performance problem not an access problem. Option D suggests revoking the masking policy, which might not be the desired solution as it weakens data security.

질문 # 308
You are developing a Snowflake Native Application that relies on external Python packages. You've successfully added the necessary packages to the stage associated with your application package using 'snowflake-cli' during development. However, when testing the application in a consumer account, you encounter errors indicating that these packages are not found. What are the most likely reasons for this issue and how can you resolve them?

A. The packages were not correctly added to the stage. Verify that the packages are in the stage specified in the 'snowflake.yml' file, and that the application has the necessary permissions to read from the stage within the setup script.
B. The stage is not automatically shared with the consumer account as part of the application package. Ensure that your setup script includes a step to create a share and grant usage on the stage to the consumer account.
C. The consumer account does not have access to the Snowflake Marketplace where the packages are hosted. Request the consumer to enable access to the required marketplace listings.
D. The 'snowflake.yml' file does not correctly specify the stage where the Python packages are located. Update the 'snowflake.yml' file to include the correct stage URL and ensure the application's setup script creates the stage and uploads the packages.
E. The consumer account's Python environment is incompatible with the packages used by the application. Instruct the consumer to update their Python environment to match the application's requirements.

정답：A,D

설명：
Options B and C are correct. Option B addresses the core issue of verifying that the Python packages are in the correct stage and that the application has permissions to read from it. If the packages aren't staged correctly or accessible, the application will fail to find them in the consumer account. Option C hits on a crucial configuration aspect if 'snowflake.ymr doesn't point to the right stage, the application won't know where to find the packages even if they exist. Sharing is implicitly handled by native apps so the share is not the problem. Consumers do not update python enviroments. Applications can not access the marketplace of the user's account.
