NEW QUESTION # 13
Which Snowflake feature allows users to encapsulate a series of SQL statements into a reusable database object, facilitating modular code development?
Answer: D
Explanation:
In Snowflake, a Stored Procedure is the primary object used for procedural logic and the encapsulation of multiple SQL statements. Unlike standard functions that are typically restricted to returning a single value or a table based on an input, Stored Procedures are designed to perform administrative tasks, wrap complex business logic, and execute a sequence of operations-such as DDL (Data Definition Language) and DML (Data Manipulation Language) commands-within a single callable object.
Modular code development is facilitated by Stored Procedures because they allow analysts and developers to write logic once and reuse it across various workflows. For example, a procedure can be written to truncate a staging table, call a COPY INTO command, and then execute several INSERT statements into a final fact table. This "wrapper" approach ensures consistency, as any change to the logic only needs to be updated in the procedure definition rather than in every script or task that uses it.
Evaluating the Options:
* Option B is incorrect because a Materialized View is a pre-computed result set used to improve query performance; it does not "encapsulate a series of statements" for procedural execution.
* Option C is incorrect because while User-Defined Functions (UDFs) provide reusability, they are generally intended for calculations or data transformations that return a result. They are much more restricted than procedures; for instance, a UDF cannot execute DDL commands like CREATE TABLE.
* Option D is incorrect because a Common Table Expression (CTE) is a temporary named result set defined within the execution scope of a single SELECT, INSERT, UPDATE, or DELETE statement. It is not a persistent database object and cannot be reused across different sessions or scripts.
* Option A is the correct answer. Snowflake Stored Procedures can be written in multiple languages (JavaScript, Snowflake Scripting/SQL, Python, Java, or Scala), providing the flexibility needed for sophisticated, modular automation in a data pipeline.
NEW QUESTION # 14
You are tasked with creating a dashboard that displays the average transaction amount for each customer segment. However, sensitive customer information, such as credit card numbers, is stored in the 'TRANSACTIONS table and protected by Dynamic Data Masking. The masking policy replaces the credit card number with 'XXXX-XXXX-XXXX-XXXX'. The dashboard needs to allow analysts to drill down into individual transactions to identify fraud patterns, but without exposing the actual credit card numbers. Which of the following approaches is the MOST secure and efficient way to achieve this?
Answer: A
Explanation:
Option A is the most secure and efficient approach. Dynamic Data Masking is designed to automatically apply masking policies to columns when they are queried, regardless of whether the query is executed directly or through a view. This ensures that analysts will always see the masked credit card numbers, preventing unauthorized access to sensitive data. Options C and E introduce external services, while Option D weakens masking and option B does not apply the masking by itself. Role hierarchy is an authorization concept, not a masking concept.
NEW QUESTION # 15
How do materialized views differ from secure views in data analysis?
Answer: B
Explanation:
Secure views offer enhanced data security without precomputing data, distinguishing them from materialized views.
NEW QUESTION # 16
You have a Snowflake table 'CUSTOMER ORDERS with columns 'CUSTOMER ID', 'ORDER DATE, and 'ORDER AMOUNT. You need to calculate the cumulative sum of 'ORDER AMOUNT' for each customer, ordered by 'ORDER DATE. However, due to potential late-arriving data, you also need to implement a windowing function that resets the cumulative sum if there's a gap of more than 30 days between consecutive orders for a customer. Which SQL query best accomplishes this?
Answer: B
Explanation:
Option C correctly uses a conditional partitioning approach. UG(ORDER DATE, 1, ORDER DATE) OVER (PARTITION BY CUSTOMER_ID ORDER BY ORDER_DATE)' calculates the previous order date for each customer. (ORDER_DATE - 1, ORDER DATE) OVER (PARTITION BY CUSTOMER ID ORDER BY ORDER DATE) > 30)' creates a boolean expression that is true when the difference between consecutive order dates exceeds 30 days. This boolean expression is then used as a secondary partition key, effectively restarting the cumulative sum whenever a gap of more than 30 days occurs. The primary partition is still 'CUSTOMER ID' , ensuring sums are calculated within each customer's order history. The ordering of 'ORDER_DATE is essential for the cumulative sum to be calculated chronologically.
NEW QUESTION # 17
A financial institution uses Snowflake to store customer transaction data'. They need to create a dashboard that visualizes daily transaction volume and average transaction amount for fraud detection purposes. This dashboard needs to be automatically updated every hour. The current dashboard query performance is slow, especially during peak hours. Given that the 'TRANSACTIONS table contains billions of rows, which of the following strategies would BEST optimize both the query performance and the automated update process?
Answer: C
Explanation:
Materialized views are designed for pre-computation of aggregations, providing significant performance improvements. Scheduling a task to refresh the materialized view ensures automatic updates. Regular views are calculated at query time and would not improve performance. Increasing warehouse size (C) might help, but it's not the most efficient solution. Temporary tables are not persistent and truncation/reload is inefficient. Dashboard caching (E) does not solve underlying Snowflake performance issues.
