질문 # 99
You are developing a Snowflake Native Application that offers a data anonymization service to consumers using Snowpark Container Services. The service accepts a dataset from the consumer's Snowflake account, performs anonymization within the container, and then writes the anonymized data back to a new table in the consumer's account. Which of the following is a correct and secure combination of actions required to successfully achieve this data transfer, assuming the container is already built and pushed to Snowflake's registry? (Select all that apply)

A. The application package owner must grant the 'IMPORTED PRIVILEGES' privilege on the database containing the anonymization logic to the consumer's account before installation.
B. The container service must use Snowflake's internal API to authenticate and authorize access to the consumer's data using a database role assigned via entitlement.
C. The consumer must grant the USAGE privilege on the database containing the table to be anonymized to the application during installation.
D. The application package must contain a setup script that creates a new stage in the consumer's account to facilitate data transfer.
E. The consumer must grant CREATE TABLE privilege on the database where the anonymized data should be stored to the application's service account via an entitlement.

정답：B,E

설명：
To enable data transfer from the consumer's account to the container service and back, several steps are crucial: C: Correct. The consumer needs to grant CREATE TABLE privilege using an entitlement, specifically to the service account associated with the Snowpark Container Service within the Native App, for the database where the anonymized data will be writtem This ensures the application can create the new table. E: Correct. Snowflake's internal APIs provide a secure and managed way for the container service to authenticate and authorize against the consumer's Snowflake account. Database roles and entitlements are key for managing these permissions. Roles are assigned to the container's service account, enabling it to perform actions with the necessary privileges. A: Incorrect . IMPORTED PRIVILEGES grant access to objects within the provider's (application developer) account, not objects within the consumer's account. B: Incorrect. While the consumer may grant USAGE on the database, this doesn't give specific access to the table. SELECT privileges would be required for the application to read the data from the specified table. D: Incorrect. Creating stages programmatically within the consumer's account is not a standard or recommended part of Native Apps. Stages are generally managed separately and access is granted via roles and privileges.

질문 # 100
You are preparing to deploy a Snowflake Native Application to the Snowflake Marketplace. You have implemented versioning using the 'VERSION' clause in your setup script. Your application relies on a specific shared data source that is only available in the AWS us- west-2 region. To ensure that consumers in other regions can still install and use your application, you decide to offer different versions with region-specific logic. Which of the following approaches is the MOST effective and recommended to manage region-specific configurations and data sharing across multiple versions of your Snowflake Native Application?

A. Implement conditional logic within the application's stored procedures to check the current region and adjust data sharing and execution accordingly using Package all configurations within a single version.
B. Use separate schemas within the application package for each region, and configure application roles with permissions to only access schemas relevant to their region. No changes to code logic are required.
C. Implement a build process that generates region-specific setup scripts based on environment variables using a CI/CD pipeline. Each version of the application will then contain the right setup script based on the target region.
D. Use the 'PATCH' clause during application deployment to selectively modify the configuration based on the target region. Deploy the same application package to all regions.
E. Create separate application packages for each region, containing region-specific configurations and data sharing setups. This ensures consumers only install the version relevant to their region.

정답：C

설명：
The most effective approach is to utilize a CI/CD pipeline to generate region-specific setup scripts. This allows you to manage region-specific configurations declaratively within your code repository and ensures a consistent and repeatable deployment process across all regions. Creating separate application packages (Option A) becomes difficult to manage and update. Conditional logic (Option B) can become complex and harder to maintain. PATCH (Option C) is not intended for such fundamental configuration differences. Using different schemas (Option E) does not address where the data resides, it just provides access control.

질문 # 101
An application provider creates a Snowflake Native App that needs to access sensitive data within the consumer's account. The provider has already defined an APPLICATION ROLE named Which of the following combination of actions are required to grant the 'app_role' the ability to select data from a table named 'customer_data' in schema of database 'consumer_db' within the consumer's account? (Choose two)

A. No privileges are needed as the Application already installed in consumer account.
B. Grant the 'SELECT privilege on the 'consumer_db.app_schema.customer_data' table to the 'APPLICATION PACKAGE
C. Grant the 'USAGE privilege on the schema to the 'APPLICATION ROLE app_role' .
D. Grant the 'SELECT privilege on the 'consumer_db.app_schema.customer_data' table to the 'APPLICATION ROLE app_role'.
E. Grant the 'IMPORTED PRIVILEGES' privilege on the 'consumer_db' database to the 'APPLICATION PACKAGE.

정답：C,D

설명：
To enable an application role to access objects in the consumer account, SELECT access on the table, along with usage access to the schema, need to be granted to the APPLICATION ROLE. Granting privileges to the APPLICATION PACKAGE only makes the privileges available for granting to the application roles, it does not automatically provide access. SELECT privilege on the table and USAGE on the schema are both needed. The APPLICATION ROLE, not PACKAGE, needs the SELECT privilege to the table. IMPORTED PRIVILEGES is typically granted to share data across accounts, not within an account for a Native App.

질문 # 102
You are the developer of a Snowflake Native App, and you're designing a feature that allows consumer accounts to create custom reports based on data exposed by the application. These reports will be defined using SQL queries and stored as views within the consumer's account, referencing objects (tables, views) provided by the application. The application does NOT want to provide direct 'SELECT access on underlying application's tables. How can you enable this feature while adhering to best practices for security and access control within the Snowflake Native App Framework? (Select all that apply)

A. Utilize Data Sharing to share the underlying tables directly with the consumer account.
B. Implement a UDF that constructs and executes the user's SQL query against the application's data and returns the results.
C. Expose secure views within the application package. Consumer accounts can then create views in their account that reference these secure views.
D. Create stored procedures that execute 'CREATE VIEW' statements in the consumer's account, controlled by parameters passed from the consumer, using EXECUTE AS OWNER.
E. Grant the 'SELECT privilege directly on the application's underlying tables to a role in the consumer account.

정답：C,D

설명：
The correct answers are A and C. Option A is a strong choice. Exposing secure views from the application package allows consumer accounts to build views that reference these secure views, inheriting the security context and preventing direct access to underlying tables. Option C is also valid, but less ideal due to the potential for SQL injection if not carefully implemented. 'EXECUTE AS OWNER ensures the stored procedure creates the view with the application's privileges, but user input needs to be strictly validated. Providing direct 'SELECT access (B) violates the security constraint. Using Data Sharing (D) bypasses the application framework entirely, and could be viable, but doesn't leverage the native app framework securely. Using a UDF (E) to execute arbitrary queries against the application data is a significant security risk.

질문 # 103
You are developing a Snowflake Native Application that interacts with sensitive customer dat a. You want to implement robust security scanning before publishing to the Snowflake Marketplace. Which of the following strategies are MOST effective to detect and prevent potential vulnerabilities before submitting your application, considering limitations on marketplace pre-publication scanning capabilities?

A. Employ a third-party penetration testing service to perform a black-box test of the application after deployment in a staging environment but prior to Marketplace submission.
B. Implement a comprehensive CI/CD pipeline that includes static code analysis (SAST) using tools like SonarQube or similar, focusing on SQL injection, cross-site scripting (XSS), and insecure deserialization vulnerabilities. Include unit and integration tests with parameterized inputs. Regularly update dependency versions and scan for known vulnerabilities in third-party libraries included in your application's code (e.g., Python libraries).
C. Manually review all code for potential security flaws and ensure adherence to secure coding practices.
D. Rely solely on Snowflake's built-in scanning during the Marketplace submission process, as it covers all known vulnerabilities.
E. Only use Snowflake provided templates and example codes as these are already pre-approved from security perspectives

정답：A,B

설명：
Option B and D provides a good answer as Snowflake's Marketplace scanning is limited, a multi-layered approach is crucial. SAST and dependency scanning within a CI/CD pipeline (B) allows for early detection of many common vulnerabilities. Penetration testing (D) provides an external, real-world assessment of the application's security posture. Relying solely on Snowflake's scanning (A) is insufficient. Manual code review (C), while helpful, is prone to human error. Only using Snowflake provided templates is very restrictive and not a solution.
