Snowflake SnowPro Advanced: Data Scientist Certification Exam Sample Questions (Q46-Q51):
NEW QUESTION # 46
You are tasked with estimating the 95% confidence interval for the median annual income of Snowflake customers. Due to the non-normal distribution of incomes and a relatively small sample size (n=50), you decide to use bootstrapping. You have a Snowflake table named 'customer_income' with a column 'annual_income'. Which of the following SQL code snippets, when correctly implemented within a Python script interacting with Snowflake, would most accurately achieve this using bootstrapping with 1000 resamples and properly calculate the confidence interval?
Answer: C
Explanation:
Option A is the correct answer. It accurately implements bootstrapping by: (1) Resampling with replacement from the original data. (2) Calculating the median of each resample. (3) Computing the 2.5th and 97.5th percentiles of the bootstrap medians to obtain the 95% confidence interval. Option B calculates the mean instead of the median, and uses 'random.sample' without replacement, which is incorrect for bootstrapping. Option C doesn't resample at all, just calculates the mean of the original data repeatedly. Option D calculates the mean instead of the median. Option E calculates 90% confidence interval instead of 95%.
NEW QUESTION # 47
A data scientist needs to analyze website session data stored in a Snowflake table named 'WEB SESSIONS'. The table contains columns like 'SESSION D', 'USER_ID, 'PAGE_VIEWS', 'TIME SPENT_SECONDS', and 'TIMESTAMP. They want to identify potential bot traffic by analyzing the correlation between 'PAGE VIEWS' and 'TIME SPENT SECONDS'. Which of the following Snowflake SQL queries is the MOST efficient and statistically sound way to calculate the Pearson correlation coefficient between these two columns, handling potential NULL values appropriately?
Answer: C
Explanation:
The 'CORR function in Snowflake directly calculates the Pearson correlation coefficient and implicitly handles NULL values by excluding rows where either input is NULL. Option A is incorrect because it does not explicitly filter NULL values, though the 'CORR' function itself handles it, Option B is mathematically correct but less concise. Option C uses 'APPROX CORR, which is useful for large datasets where approximate results are acceptable, but for a general scenario without size constraints, 'CORR is preferred for accuracy. While Option E correctly calculates the correlation coefficient using covariance and standard deviation, it uses approximation functions which may impact accuracy without a necessary tradeoff.
NEW QUESTION # 48
You have a table 'PRODUCT SALES in Snowflake with columns: 'PRODUCT (INT), 'SALE_DATE (DATE), 'SALES_AMOUNT (FLOAT), and 'PROMOTION FLAG' (BOOLEAN). You need to perform the following data preparation steps using Snowpark SQLAPI:
Answer: C
Explanation:
All the described data preparation steps (A, B, C, and D) are common and relevant in feature engineering for time-series or sales data analysis. Imputing missing values using rolling averages, converting dates to categorical representations, calculating growth rates, and using flag-based transformations are all standard practices. The use of 'LEAD or 'LAG' window functions is essential for calculating , and handling edge cases (like the first day of a product's sales) is crucial for data integrity. A 'CASE statement or similar construct would be needed for the PROMOTION FLAG logic.
NEW QUESTION # 49
You are training a Gradient Boosting model within Snowflake using Snowpark Python to predict customer churn. You are using the Hyperopt library for hyperparameter tuning. You want to use the function to find the best hyperparameters. You have defined your objective function, , and the search space, Which of the following is the MOST efficient and correct way to call the function within a Snowpark Python UDF to ensure the Hyperopt trials data is effectively managed and accessible for further analysis within Snowflake?
Answer: C
Explanation:
Option D is the most complete. It correctly uses 'Trials' to store results, ensures reproducibility with 'rstate' (important for controlled experiments), and demonstrates the correct way to save the trials to a Snowflake table using session.createDataFrame(trials.trials).write.save_as_table('HYPEROPT TRIALS')'. Option C also attempts to save results but saves 'trials.trials', not 'trials.results'. 'trials.trials' contains more detailed information for the hyperopt run. Reproducibility is also not ensured, which makes Option D slightly preferable. SparkTrials is only used for Spark not Snowflake, thus eliminating Option E. Option A does not store the output, and Option B saves 'trials.results' but lacks reproducibility and only processes 'trials.results'.
NEW QUESTION # 50
You are a data scientist working with a Snowflake table named 'CUSTOMER DATA' that contains a 'PHONE NUMBER' column stored as VARCHAR. The 'PHONE NUMBER' column sometimes contains non-numeric characters like hyphens and parentheses, and in some rows the data is missing. You need to create a new table 'CLEANED CUSTOMER DATA' with a column named 'CLEANED PHONE NUMBER that contains only the numeric part of the phone number (as VARCHAR) and replaces missing or invalid phone numbers with NULL. Which of the following Snowpark Python code snippets achieves this most efficiently, ensuring no errors occur during the data transformation, and considers Snowflake's performance best practices?
Answer: D
Explanation:
Option E is the most efficient because it leverages Snowpark's built-in functions for string manipulation and conditional logic directly. It first removes all non-numeric characters using 'regexp_replace' and then uses 'iff (if and only if) to replace empty strings (resulting from cleaning) with NULL. This approach avoids using UDFs (User-Defined Functions), which can introduce overhead. Option B, although using 'regexp_replace' , requires an additional 'with_column' to handle empty strings after cleaning. Option A introduces UDF that decreases performance. Option C calls UDF with undefined 'call_udf function and 'snowflake-snowpark-python' library. Option D is missing dataframe and its transformation is not happening on top of Dataframe. Option E is preferrable over Option B, as it uses the single transformation.
