Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q82-Q87):

NEW QUESTION # 82
A Snowpark application needs to process large volumes of sensor data stored in a Snowflake table named , which includes columns , 'timestamp' , and The application must calculate a rolling average of for each over a 5-minute window. The data is not perfectly ordered by 'timestamp' within each 'sensor_id'. What is the MOST efficient and accurate way to implement this rolling average calculation using Snowpark?

A. Using a Window specification with 'orderBy('timestamp')' and 'rowsBetween(Window.unboundedPreceding, Window.currentRow)' in conjunction with and a UDF to manually calculate the rolling average within each group.
B. Using after applying a filter to select only the data within the 5-minute window, updating the filter for each new window.
C. Using a Window specification with 'orderBy('timestamp')' and 'rowsBetween(Window.unboundedPreceding, Window.currentRow)' to calculate the cumulative average, then subtracting the average from 5 minutes ago. The query will then be grouped on the sensor id.
D. Using a Window specification with 0)' and the 'avg()' window function. (Where 'to_seconds' converts a duration to seconds)
E. Implementing a Python UDTF (User-Defined Table Function) that iterates through the data for each calculates the rolling average manually, and emits the results as rows.

Answer: D

Explanation:
Option D is the most efficient and accurate. 'partitionBy('sensor_id')' ensures that the rolling average is calculated separately for each sensor. 'orderBy('timestamp'Y orders the data within each partition by timestamp. 0)' defines the 5- minute window relative to the current row, accurately capturing all readings within that window even if they are slightly out of order. 'avg(Y then efficiently calculates the average within that window. Other options are either less efficient (e.g., UDTF iteration) or less accurate (e.g., incorrect window definitions, filtering).

NEW QUESTION # 83
Consider the following Snowpark Python code snippet:

A. The function will retrieve all rows from the 'customers' table and store them in a local Pandas DataFrame before applying the function.
B. This code requires a configured Anaconda environment to run successfully.
C. The code demonstrates the Snowpark architecture, where transformations are translated into SQL and executed in Snowflake's engine. Only the final 'collect()' brings the results back to the client.
D.
E. The 'upper()' function will be executed on the client-side (where the Python code is running) for each row in the 'customers' table.

Answer: C,D

Explanation:
Options A and D are correct. Snowpark leverages Snowflake's compute resources by translating DataFrame operations (like 'with_column' and 'upper') into SQL that is executed within the data warehouse. Only the 'collect()' action materializes the results and brings them back to the client. B is wrong because the upper function executes on the server side and is translated into SQL. C is wrong because collect happens at the end after 'upper' is calculated in Snowflake. E is incorrect as the core Snowpark functionality does not require a full Anaconda environment setup - dependencies can be configured otherwise.

NEW QUESTION # 84
You have developed a Python function that performs complex data transformation on customer data'. You want to operationalize this function as a UDTF in Snowpark to process large datasets efficiently. The function takes a customer ID and a list of transaction amounts as input and returns a table with calculated risk scores for each transaction. Which of the following code snippets correctly defines and registers this UDTF in Snowpark, ensuring proper type handling and scalability?

A.
B. Options B and C are the most correct.
C.
D.
E.

Answer: B

Explanation:
Options B and C correctly defines the UDTF.Option B uses return_type and option C uses output_schema, both work. Option A is incorrect because a UDTF needs to be defined as a class with a 'process' method that yields rows, not as a function that returns a list. Option D uses an incorrect way to specify ArrayType ('array') . The other options are either syntactically incorrect or do not follow the correct UDTF definition pattern.

NEW QUESTION # 85
You are building a Snowpark application that processes a large number of PDF files stored in a Snowflake stage. You need to extract text from each PDF file using a Python UDF and store the extracted text in a Snowflake table. You are considering different approaches for loading the PDF files into the UDE Which of the following approaches would provide the BEST performance and scalability, while minimizing network traffic and memory usage?

A. Use the 'GET_OBJECT Snowflake SQL command to retrieve each file's contents and then pass the results as arguments into the UDF for processing. This allows use of pure SQL statements to access the files.
B. Use the 'snowflake.snowpark.functions.read' function in Python to read the PDF files directly from the stage within the UDF. This loads the file contents into a variable available for processing.
C. Pass the file path of each PDF file in the Snowflake stage to the UDF as a string. Within the UDF, use the 'snowflake.snowpark.files.SnowflakeFile' class to open and read the file. This will allow efficient access to the file directly from the stage.
D. Load the PDF files into a pandas DataFrame within the Snowpark application, then pass the DataFrame to the UDF. This way the PDF can be available to all workers in the dataframe.
E. Download all PDF files from the Snowflake stage to a local directory on the machine running the Snowpark application, then load the files from the local directory into the UDF.

Answer: C

Explanation:
Option C is the most efficient approach. 'snowflake.snowpark.files.SnowflakeFile' allows the UDF to directly access the PDF files stored in the Snowflake stage without transferring the entire file to the client. This minimizes network traffic and memory usage. Option A requires loading all PDF files into a pandas DataFrame, which can consume a significant amount of memory. Option B has issues relating to the file size and content restrictions and isn't suitable for many files. Option D involves downloading all files to a local directory, which is not scalable and introduces unnecessary overhead. Option E using 'GET OBJECT is outside the scope of the python api.

NEW QUESTION # 86
Consider a Snowflake table 'orders' with columns 'order_id', 'customer_id', 'order_date', and 'status'. You need to update the 'status' of all orders placed before January 1, 2023, to 'Archived'. Which of the following approaches is the most efficient and idiomatic way to achieve this using Snowpark DataFrames, assuming 'orders df DataFrame represents the 'orders' table?

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

Answer: A,C

Explanation:
Options C and D are both valid and efficient solutions. Option C leverages Snowpark's 'with_column' and 'when' functions to conditionally update the 'status' column within the DataFrame and persists the changes back to the table using 'save_as_table'. Using lit function makes sure that 'Archived' status is passed as a literal. Option D uses a direct SQL update statement executed through the Snowpark session. This bypasses DataFrame operations but directly modifies the table, which can sometimes be more efficient for simple update operations. Option A is almost correct but the with_column and filter are applied separately. Option B doesn't work due to the way update functions are implemented in Snowpark. Option E unnecessarily collects the filtered data back to the driver, creating a new DataFrame from the collected data, then applying 'with_column'. This is an inefficient approach.
