NEW QUESTION # 187
You are developing a Snowflake Native Application that manages customer dat a. You need to ensure that updates to customer records are idempotent. Your application uses a stored procedure 'update_customer(customer_id INT, new_email VARCHAR)' to update customer emails. How can you modify this procedure to guarantee idempotency, assuming that customer data changes are tracked with a 'last_updated' column of type TIMESTAMP NTZ?
Answer: B
Explanation:
Option C leverages the 'MERGES statement for idempotent updates. By comparing the existing and new email and only updating if different, and comparing the Alast_updated' timestamp, it prevents redundant updates if the procedure is called multiple times with the same input. Optimistic locking (A) is a valid concurrency control mechanism but doesn't directly guarantee idempotency in this scenario. 'COMMIT (B) affects transaction behavior, not idempotency. Creating a separate table (D) adds complexity but doesn't inherently ensure idempotency of the update_customer' procedure itself. 'TRY...CATCH& (E) provides error handling but doesn't address idempotency.
NEW QUESTION # 188
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)
Answer: A,B,E
Explanation:
The most effective steps, in order, are: 1. D: Use 'SYSTEM$GET_PKG INSTALLATION ERRORS' in the provider account. This function is specifically designed to provide detailed error information about failed installations. It's the quickest way to get actionable insights. 2. B: Review Snowflake Event Tables. After getting a specific error from the , correlate the information with your application+s specific event logs. This helps understand the application-level context of the error. 3. A: Examine consumer's ACCOUNT_USAGE views. While less specific, checking query history and error logs in the consumer account can provide valuable insights into the environment and any potential conflicts. Option C is not the first step because Native Apps should ideally handle role creation. Sharing entire metadata (Option E) is a security risk and rarely necessary.
NEW QUESTION # 189
You have a Snowflake Native Application that utilizes a managed table. After upgrading your application to version 2.0, some users report that they are missing data in the managed table. After investigation, you realize version 2.0 changed the schema of the managed table and also did not properly migrate all the data from old format into new format. Which of the following steps should be taken to address the missing data after upgrading a Snowflake Native Application?
Answer: E
Explanation:
Option D is the correct approach. By dynamically detecting the upgrade and running a data migration script, the application ensures data integrity during the upgrade process. The data migration script will convert data from old format to new format. Option A is almost correct, however we don't assume the user is at 1.0. The application may be updated from earlier versions as well. Option B is not feasible due to operational overhead of doing it for each consumers and requires high privilege on consumer side which is not allowed for native apps. Option C is not practical or scalable. Managed tables are managed by your application code within the package, so Snowflake support won't perform data manipulation (Option E).
NEW QUESTION # 190
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: C,D
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 # 191
You are developing a Snowflake Native Application designed to be deployed by various consumers from the Snowflake Marketplace. The application interacts with user-provided data through secure UDFs and external functions. To ensure minimal impact and prevent unintended data access, how should you configure the application's security context and privileges when creating the application package?
Answer: D
Explanation:
The best practice for securing Native Applications is to follow the principle of least privilege. Granting 'OWNERSHIP' or 'ALL PRIVILEGES' (A, D) is far too permissive and poses a significant security risk. While creating roles within the application (C) offers some control, it doesn't leverage the explicit privilege granting mechanism designed for Native Apps. Option B is partially correct but incomplete. Option E is the most secure and correct approach. It uses a dedicated application role with minimal required privileges CUSAGE on database, 'EXECUTE on UDFs/external functions) and 'CALL to grant 'USAGE' on the data share provided by the consumer, ensuring that the application can only access the explicitly shared data and execute the intended functions.
