Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q139-Q144):

NEW QUESTION # 139
You are developing a Snowpark application to perform complex data transformations on a large dataset stored in Snowflake. You need to optimize the application's performance. Which of the following strategies are MOST effective for improving performance within Snowpark?

A. Taking advantage of Snowpark's lazy evaluation by chaining transformations together before triggering execution with an action like 'collect()' or 'write()'.
B. Using user-defined functions (UDFs) written in Python for all transformations, regardless of complexity.
C. Leveraging Snowpark's optimized functions and operations whenever possible, even if it requires rewriting some Python code.
D. Materializing intermediate DataFrames aggressively to reduce memory usage.
E. Using the 'collect()' method frequently to retrieve small subsets of data to the client for processing.

Answer: A,C

Explanation:
Snowpark's optimized functions (B) are designed to be executed efficiently within the Snowflake engine. Lazy evaluation (E) allows Snowpark to optimize the entire query plan before execution. UDFs (A) can be useful, but should be used judiciously as they can introduce overhead. Materializing intermediate DataFrames (C) can increase storage costs and may not always improve performance. 'collect()' (D) should be avoided for large datasets as it moves data out of Snowflake.

NEW QUESTION # 140
You are setting up a development environment for Snowpark using Anaconda and encounter the following error: 'ModuleNotFoundError: No module named 'snowflake.snowpark". You have already installed the package using pip. What is the MOST likely cause of this error and how do you resolve it?

A. The Anaconda environment is not activated. Activate the environment using 'conda activate
B. The Snowflake account identifier is not properly configured in your environment variables. Verify that 'SNOWFLAKE ACCOUNT is correctly set.
C. The Snowflake driver is not installed. Install the Snowflake driver using 'pip install snowflake-connector-python'
D. The 'snowflake-snowpark-python' package was installed in a different Anaconda environment than the one you are currently using. Ensure you are in the correct environment when running your Snowpark code.
E. The 'snowflake-snowpark-python' package is not compatible with the version of Python installed in your Anaconda environment. Upgrade Python to the latest version.

Answer: A,D

Explanation:
The most common reasons for 'ModuleNotFoundErroff are that the Anaconda environment is not activated (B), meaning the Python interpreter doesn't know where to find the installed packages, or the package was installed in a different environment (D) than the one being used. While Python version compatibility (A) and Snowflake driver (C) can cause issues, they usually manifest as different errors. A misconfigured account identifier (E) would prevent a connection to Snowflake, but wouldn't directly cause a 'ModuleNotFoundError' for the Snowpark library itself.

NEW QUESTION # 141
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. 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()'.
B. 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.
C. 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.
D. Download all the image files to the Snowpark client, process them locally using Pillow, and then upload the extracted metadata to Snowflake using session
E. 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.

Answer: A

Explanation:
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.

NEW QUESTION # 142
You have a Snowpark application that performs machine learning inference on a large dataset of images stored in Snowflake. The inference logic is implemented within a Python UDF that utilizes a pre-trained deep learning model. You notice that the inference process is slow and consumes a significant amount of resources. Which of the following optimization techniques would be MOST effective in improving the performance and reducing the resource consumption of this application?

A. Ensure the virtual warehouse used by Snowpark is configured with auto-scaling to dynamically adjust the compute resources based on the workload.
B. Optimize the UDF code to use batch processing techniques to process multiple images in a single call, reducing the overhead of UDF invocation.
C. Leverage the Snowpark Session object to manage the lifecycle and scope of the pre-trained model within the UDF, ensuring it is loaded only once per session.
D. Persist the pre-trained deep learning model in a database table or stage and load it into the UDF's memory during each invocation to avoid repeated loading.
E. Use external functions instead of UDFs.

Answer: A,B,C

Explanation:
Auto-scaling helps manage resources dynamically. Batch processing reduces UDF overhead by processing multiple images in one call. Storing the model in a stage requires repeated loading. Managing the model's lifecycle within the Snowpark Session prevents reloading the model. External functions require data transfer out of Snowflake.

NEW QUESTION # 143
You are using Snowpark Python to create a DataFrame from an existing Snowflake table "SALES DATA'. You want to apply a user- defined function (UDF) to each row of the DataFrame to calculate a custom sales metric. The UDF requires access to the 'session' object. Which of the following approaches is correct for defining and applying the UDF in Snowpark?

Answer: E

Explanation:
Option E is the correct approach. To access the session object from within the UDF, you can import it when registering the UDF with the session. It should be imported inside the function and use the decorator. The input_types parameter should be set to 0, since this allows for session access.
