Snowflake SnowPro Advanced: Data Analyst Certification Exam Sample Questions (Q16-Q21):

NEW QUESTION # 16
Which of the following statements are true regarding the use of user-defined functions (UDFs) in Snowflake to optimize query performance, especially when compared to equivalent SQL expressions? (Select all that apply)

A. UDFs can sometimes improve code readability by encapsulating complex logic, but this rarely translates into significant performance gains.
B. SQL UDFs generally perform better than Java or Python UDFs because they are executed natively within the Snowflake engine.
C. External functions and UDFs are the same, both reside outside snowflake.
D. UDFs can be useful when the same complex calculation needs to be performed multiple times within a single query, potentially reducing code duplication and improving maintainability, thereby indirectly improving performance by simplification.
E. Snowflake UDFs, especially those written in Java or Python, can introduce performance overhead due to the cost of invoking the external runtime environment.

Answer: A,B,D,E

Explanation:
UDFs can improve code readability but don't always translate to performance gains. Java and Python UDFs incur overhead because they run outside the Snowflake engine. SQL UDFs are generally faster. They are useful for code reuse. External functions and UDFs are not the same: UDFs reside inside snowflake.

NEW QUESTION # 17
You have created a forecasting model in Snowflake to predict customer churn based on historical data'. The model is named 'CHURN FORECAST MODEL'. After running the forecast, you need to evaluate the model's performance and understand its accuracy.
Which of the following methods or SQL commands can you use to accomplish this effectively?

A. Use the 'SELECT FROM command to get a summary of the model's performance, including error metrics. Additionally, manually compare the forecasted values to the actual values to calculate error metrics.
B. Use the 'SHOW MODELS command to view the model's metadata, including accuracy metrics like Mean Absolute Error (MAE) and Root Mean Squared Error (RMSE).
C. There is no native way to evaluate forecasting model performance in Snowflake. You must manually calculate error metrics by comparing the forecast results with actual historical data using SQL queries.
D. Use the 'DESCRIBE MODEL CHURN FORECAST MODEL' command to retrieve model statistics such as the features used and their importance in the model.
E. Use the function to download the model's internal representation and analyze it using external machine learning libraries.

Answer: A

Explanation:
Option E is the most comprehensive approach. The command 'SELECT FROM MODEL', EXPLAIN is the appropriate command to view model performance metrics. While snowflake can get summary stats. It's best to manually calculate error metrics by comparing the forecasted values with the actual historical data, that ensures a comprehensive evaluation. 'SHOW MODELS' command does not provide detailed accuracy metrics. 'SYSTEM$GET_MODEL' is not intended for model evaluation. 'DESCRIBE MODEL' provides details about model features but not the statistical performance. Snowflake supports built-in forecasting, so model calculation error is unnecessary.

NEW QUESTION # 18
How do user-defined functions (UDFs) contribute to data analysis in SQL?

A. UDFs hinder query optimization.
B. UDFs can only be used with materialized views.
C. UDFs restrict data analysis to predefined operations.
D. They allow customization and extension of SQL functionalities for specific data operations.

Answer: D

Explanation:
UDFs allow customization and extension of SQL functionalities, enabling specific data operations beyond predefined limits.

NEW QUESTION # 19
You have a large dataset in Snowflake containing customer order information stored in a table named 'ORDERS' with columns 'ORDER_ID' ONT), 'CUSTOMER_ID' ONT), 'ORDER_DATE (DATE), 'TOTAL_AMOUNT' (FLOAT), and 'DISCOUNT_APPLIED' (BOOLEAN). You need to use Snowsight dashboards to analyze customer spending behavior and identify potential outliers. Which of the following visualizations, combined with appropriate SQL queries, would be MOST effective in identifying customers with unusually high or low order values? (Select TWO)

A. Option A
B. Option C
C. Option D
D. Option B
E. Option E

Answer: A,B

Explanation:
Options A and C are the most effective. A Box Plot (A) is ideal for identifying outliers in a distribution. By visualizing the distribution of total order amounts per customer, you can easily spot customers with unusually high or low spending. A Scatter Plot (C) directly shows the relationship between customer ID and total spending, making it easy to visually identify outliers based on their position relative to other data points. Option B is more suitable for trend analysis over time, and options D and E are useful but don't directly highlight individual customer outliers in terms of order value.

NEW QUESTION # 20
Identify the correct action involved in performing an exploratory ad-hoc analysis.

A. Utilizing ad-hoc queries to examine patterns and anomalies
B. Analyzing only a small fraction of the available data
C. Relying solely on predefined queries without exploration
D. Focusing on established trends without investigating anomalies

Answer: A

Explanation:
Ad-hoc analysis involves using queries to explore patterns and anomalies within data, deviating from predefined routines.

NEW QUESTION # 21
