최신 Snowflake Certification SPS-C01 무료샘플문제 (Q303-Q308):

질문 # 303
You have a Snowpark DataFrame 'employees df representing employee data'. You need to update the 'salary' column for employees in the 'Sales' department by applying a 10% increase. Which of the following Snowpark code snippets correctly performs this update? Assume a Snowflake table named 'employees' exists and 'employees df' is correctly created from it.

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

정답：C,E

설명：
Options C and E are correct. Snowpark does not have an 'update' method directly on DataFrames like some other Spark-based DataFrame implementations. The correct way to update the data is to use 'with_column' along with 'when' and 'otherwise' from 'snowflake.snowpark.functions' to conditionally update the 'salary' column based on the 'department'. The part is crucial to persist the changes back to the Snowflake table after the transformation. Option C imports the required functions using 'from snowflake.snowpark.functions import when, cor and Option E directly uses the dataframe to invoke function and column names. Option A and D are incorrect because Snowpark does not provide an 'update' or direct save after filtering like that for this type of update. Option B is also incorrect because the update function doesn't exist on dataframes.

질문 # 304
You're developing a Snowpark Python application to process log files stored in an external stage 's3_logs'. These logs are in plain text, with each line representing a log entry. You need to filter log entries based on a specific keyword and extract timestamps from the matching lines. Which of the following approaches, using and Snowpark DataFrames, will efficiently accomplish this, avoiding unnecessary data transfer to the client?

A. Create an external function that accesses the files directly from S3, performs the filtering and timestamp extraction, and returns the results. Then create a Snowpark DataFrame to invoke the external function.
B. Use pattern=' .log')' to load all log files into a Snowpark DataFrame with a single column containing the log lines. Then, filter the DataFrame using like' to find lines containing the keyword and extract timestamps using regular expressions in a subsequent select statement.
C. Create a UDF that accepts a 'SnowflakeFile' object as input, reads the file line by line inside the UDF, filters lines based on the keyword, extracts timestamps, and returns a list of timestamps. Call this UDF on a Snowpark DataFrame created using 'session.read.option('PATTERN', ' .10g').format('CSV').load('@s3_logs'V.
D. Download each log file using 'SnowflakeFile.get' , read the file line by line in the client application, filter lines based on the keyword, extract timestamps, and then create a Snowpark DataFrame with the extracted timestamps.
E. Use 'session.read.option('PATTERN', ' to load all log files into a Snowpark DataFrame with a single column containing the log lines. Create a UDTF that reads a partition of the DataFrame, filters lines based on the keyword, extracts timestamps, and returns a table of timestamps.

정답：E

설명：
Option E provides the most efficient solution. By using 'session.read.option('PATTERN', ' you load the data directly into a DataFrame within Snowflake. A UDTF (User-Defined Table Function) is then used to process each partition of the DataFrame, performing the filtering and timestamp extraction in parallel within the Snowflake environment, minimizing data transfer to the client. Option A is highly inefficient as it downloads all files to the client. Option B is less efficient than E because it processes all rows through a single UDF instead of distributed processing using UDTF. It also assumes all log data can be held in a single dataframe which can create memory issues Option C is similar to B and it uses UDF instead of UDTF making it less efficient. Option D introduces external dependencies to the solution.

질문 # 305
Consider a Snowflake table named 'raw events' containing web event data in a VARIANT column called 'event data'. Each 'event_data' JSON object may contain an array of product IDs under the key 'product_ids', and another array of user IDs who interacted with those products under the key 'user_ids'. These arrays are not guaranteed to be the same length, and a missing array should be handled gracefully (return null/empty result for that row rather than throwing error). Your objective is to create a Snowpark DataFrame that flattens both arrays into rows, pairing each product ID with each user ID for the specific event, generating as many rows as possible, and including event timestamp. You can use a zero-based index for the array elements using 'ARRAY CONSTRUCT()' and then using that array for using the EXPLODE function. Which of the following are necessary steps to fulfill this requirement and which are not?

A. Use two separate 'withColumn()' transformations followed by two 'explode()' operations to flatten each array independently.
B. Use 'iff()' or 'case when' and and other relevant function to handle exception cases.
C. Convert the 'product_ids' and 'user_ids' arrays to strings using and before applying 'explode'.
D. Use function to dynamically create an array of indices for the 'explode' function and use and function to handle missing values
E. Use a 'LEFT OUTER JOIN LATERAL FLATTEN' to flatten 'product_ids' and 'user_ids', and then use 'nvl()' or 'coalesce()' to handle cases where one or both arrays are missing.

정답：B,D,E

설명：
Options A, C, and E are correct. A: Using and along with ensures dynamic index array generation and graceful handling of missing or non-numeric dat a). C: Using 'LEFT OUTER JOIN LATERAL FLATTEN' allows both 'product_ids' and 'user_ids' arrays to be flattened, even if one or both are missing. The LEFT JOIN ensures all rows from the original data are kept. The use of handles cases where either array is null or empty, preventing errors and providing default values. E:Using or 'case when' handles exception and different length of arrays.

질문 # 306
You have a Snowpark Python stored procedure that needs to access environment variables stored securely within Snowflake. Which of the following code snippets demonstrates the correct way to retrieve the value of an environment variable named 'API KEY' within your stored procedure?

정답：E

설명：
Snowflake Snowpark sessions use the method to retrieve user-defined session parameters, including those that may be set to environment variables. The method allows access to parameters set at the account, user or session level. The 'os.envirorf (A) will not work in the Snowflake environment. B, D, and E are not valid Snowpark API methods for retrieving parameters.

질문 # 307
You have a Snowflake stage containing image files. You need to write a Snowpark Python application that extracts metadata (e.g., image resolution, format) from these images and stores the metadata in a Snowflake table. You want to leverage a Python library, such as Pillow (PIL), for image processing. Which of the following steps are necessary to correctly and efficiently implement this?

A. Upload the Pillow library as a zip file to a Snowflake internal stage. Create a Snowpark stored procedure. In the stored procedure code, import the Pillow library using 'import zipfile; sys.path.append('pillow.zip'); from PIL import Image'. Read the image files using , process them with Pillow to extract metadata, and then insert the metadata into the Snowflake table.
B. Create a Conda environment specification file ('environment.yml') that includes Pillow as a dependency. Upload the 'environment.ymr file to a Snowflake stage. Use 'session.add_packages' in the Snowpark session to load the Pillow library. Read the image files using , process them with Pillow, and then write the metadata to a Snowflake table using 'session.write_pandas()'.
C. Create a Python UDF (User-Defined Function) that uses Pillow to extract metadata from the image files. Register the UDF with Snowflake. In a Snowpark DataFrame transformation, call the UDF for each image file to extract the metadata. Finally, write the resulting DataFrame to a Snowflake table.
D. Use Snowpark's built-in image processing functions to extract metadata directly from the image files. This eliminates the need for external libraries like Pillow.
E. Download all the image files to the Snowpark client, process them locally using Pillow, and then upload the extracted metadata to Snowflake using session

정답：B

설명：
Option B is the MOST correct. Using a Conda environment specification file ('environment.yml') and 'session.add_packages' is the recommended way to manage dependencies in Snowpark. It ensures that the correct version of Pillow is available and simplifies the deployment process. Option A is an older method and may not be as reliable. Option C involves UDFs which, while valid, can be less efficient than using native Snowpark functionalities directly. Option D is incorrect, Snowflake doesn't have built-in image processing functions. Option E again defeats the purpose of server-side processing.
