Snowflake Certified SnowPro Specialty - Snowpark 認定 SPS-C01 試験問題：

問題 #1
A data engineer is tasked with transforming a large dataset of customer transactions using Snowpark Python. The dataset contains personally identifiable information (PII) that needs to be masked before further analysis. They decide to use a UDF to perform the masking. Consider the following Python UDF:

The engineer registers this UDF and attempts to apply it to a column named 'customer email' in a Snowpark DataFrame named 'customer data'. Which of the following code snippets is the MOST efficient and secure way to apply this UDF and replace the 'customer email' column with the masked values?

A.

B.

C.

D.

E.

問題 #2
A data engineer is developing a Snowpark application using Python and needs to connect to Snowflake. They want to avoid hardcoding credentials directly in the script and utilize environment variables for authentication. Which of the following approaches is the MOST secure and RECOMMENDED way to retrieve Snowflake connection parameters (account, user, password, database, schema, warehouse, role) from environment variables and establish a Snowpark session?

A. Utilize the 'Session.builder.getorcreate()' method, assuming that Snowflake connection information (user, password, account, warehouse, etc.) are already set as environment variables with standard names, and let Snowpark automatically infer the parameters.
B. Leverage the 'snowflake.connector.connect()' function with 'os.environ.get()' for credentials and then create a Snowpark session from the connection using Session. builder. from_connection(connectiony.
C. Store all connection parameters as a JSON string in a single environment variable and parse it within the Snowpark application.
D. Manually retrieve each parameter using 'os.environ.get()' and pass them directly into the 'Session.builder.configs()' method.
E. Use the SnowCLl to configure a connection profile, and then reference this profile name when creating the Snowpark session. Ensure each environment variable is also separately available, but are not explicitly called in the code to establish connection but only to set up SnowCLl.

問題 #3
You have a Snowpark DataFrame containing sensor data'. You need to write this data to a Snowflake stage 'sensor_stage' , creating a new set of files every hour based on the 'timestamp' column (data type: Timestamp). You also want to ensure that the file names include the hour of the timestamp and are written in Avro format with Zstandard compression. The directory structure on the stage should reflect the hourly partitioning. Which of the following approaches offers the most efficient and scalable way to achieve this, while minimizing the number of files written per hour?

A. Define a stored procedure that iterates through hourly intervals, filters the DataFrame based on the current hour, and writes the filtered DataFrame to the stage using 'df.write.format('avro').option('compression', 'zstd').mode('append').save(f'@sensor_stage/hour={current_hour}/')'
B. Using scala user defined function (UDF) for write dataframe into stage in avro file format partitioned by Hour and calling it in snowpark dataframe.
C. Create a new DataFrame by adding an 'hour' column extracted from the 'timestamp' column. Then use 'df.write.partitionBy('hour').format('avro').option('compression', 'zstd').mode('append').save('@sensor_stage/')'.
D. Write a Python script that connects to Snowflake, retrieves the entire DataFrame, iterates through each row, determines the hour from the 'timestamp', and writes each row to a separate Avro file named after the hour in the 'sensor_stage'
E. Create a view on top of the data and schedule a task which create file in avro with zstd compression by running the select statment with group by hour.

問題 #4
You are developing a Snowpark application to ingest a large dataset into Snowflake. You have a DataFrame with a schema that matches the target table 'TARGET TABLE. Due to network constraints, you need to optimize the insertion process to minimize the number of API calls. Which of the following approaches would provide the MOST efficient way to insert the data?

A. Directly use the method, without any intermediate transformations.
B. Stage 'data_df to an internal stage, then load the data from stage to the table using COPY INTO command.
C. Load the DataFrame into chunks of 1000 records into target table by using insert_into() function iteratively
D. Iterate through the rows of 'data_df , constructing and executing a separate INSERT statement for each row using 'session.sql()'.
E. Convert 'data_df to a Pandas DataFrame using and then use to insert the data.

問題 #5
You are developing a Snowpark application that processes large volumes of JSON data from an external stage. Initial testing on a MEDIUM warehouse results in significant query queuing. You suspect the issue is CPU bound due to complex JSON parsing and UDF execution within Snowpark. Considering only warehouse sizing options and assuming cost is a secondary concern to performance during peak processing hours, which strategy is MOST effective for optimizing performance? Consider the impact on concurrency.

A. Upgrade the warehouse to a LARGE. This provides more CPU and memory for the existing workload, potentially resolving the bottleneck and improving overall throughput.
B. Scale out to multiple MEDIUM warehouses using auto-scaling. This increases concurrency, allowing more queries to run simultaneously, but might not address CPU-bound operations within a single query.
C. Upgrade to an X-LARGE or higher warehouse, leveraging the increased resources to handle complex parsing and UDF execution more efficiently. Monitor CPU utilization after the upgrade.
D. Implement query acceleration using materialized views to pre-compute JSON parsing results. Then, add warehouses as needed for concurrent requests
E. Scale down to a SMALL warehouse. Smaller warehouses are optimized for smaller operations and can process certain types of operations faster. This could improve latency.
