Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q275-Q280):

NEW QUESTION # 275
Consider the following Snowpark Python code snippet for creating a stored procedure:

What is the PRIMARY reason for explicitly defining 'input_types' and during the stored procedure registration?

A. To allow Snowflake to automatically generate documentation for the stored procedure's input and output types.
B. To allow Snowsight to correctly display the stored procedure's metadata, making it easier for users to understand its functionality.
C. To ensure data type safety and schema validation during deployment and execution, preventing unexpected runtime errors due to type mismatches between the stored procedure and the calling environment.
D. To enable the stored procedure to be called from other programming languages besides Python.
E. To improve the performance of the stored procedure by enabling compile-time optimizations.

Answer: C

Explanation:
The primary reason for explicitly defining and 'return_type' during stored procedure registration is to enforce data type safety and schema validation. Snowflake uses these definitions to verify that the data passed to the stored procedure and the data returned by the stored procedure conform to the expected types. This helps prevent unexpected runtime errors that can occur due to type mismatches between the stored procedure's code and the calling environment. Without explicit type definitions, Snowpark would rely on runtime inference, which can be less reliable and harder to debug in production scenarios.

NEW QUESTION # 276
You have a Python function that calculates a complex statistical measure on a given row of a DataFrame. You want to apply this function to each row of a Snowpark DataFrame in a distributed manner. Which of the following is the MOST efficient way to achieve this?

A. Use the "map' method on the Snowpark DataFrame's underlying RDD (Resilient Distributed Dataset) and pass the Python function as an argument.
B. Use the 'apply' method on the Snowpark DataFrame, passing the Python function as an argument.
C. Use Snowpark's 'sprocs feature to create stored procedure and call the Python function.
D. Iterate through the rows of the Snowpark DataFrame and call the Python function on each row individually.
E. Create a Pandas UDF (User-Defined Function) using decorator and apply it to the Snowpark DataFrame.

Answer: E

Explanation:
Pandas UDFs (User-Defined Functions) are designed for efficient row-wise operations on Snowpark DataFrames. The @pandas_udf decorator enables Snowpark to execute the function in a distributed manner across Snowflake's compute resources, maximizing performance for row-by-row calculations. 'apply' method doesn't exist directly on Snowpark DataFrames. Iterating through rows (Option C) is extremely inefficient. Option D involves RDD which is not exposed directly with Snowpark DataFrames. While option E is an alternative it introduces unnecessary overhead.

NEW QUESTION # 277
You are developing a Snowpark application that needs to connect to Snowflake using programmatic access. You want to use a secure method of authentication. Which of the following methods, when passed as parameters to the 'snowpark.Session.builder.configS method, would be MOST secure and appropriate for production environments?

A. Using 'oauth_access_token' obtained from an external OAuth server.
B. Passing the 'user' and 'password' directly, but retrieving the 'account' from an environment variable.
C. Using 'private_key' stored securely and referencing it using 'private_key_file'.
D. Setting the 'authenticator' parameter to 'snowflake' and rely on default Snowflake authentication mechanism assuming it setup correctly
E. Passing the 'user', 'password', and 'account' parameters directly as strings.

Answer: A,C

Explanation:
Using 'oauth_access_token' and 'private_key' (especially when stored securely) are more secure than directly passing username and password. OAuth and Key Pair authentication are recommended for production environments because they avoid storing or transmitting passwords directly. Options A & B are vulnerable because they expose credentials directly in the code or configuration. Option E is incorrect because simply setting the authenticator does not ensure the user authentication will happen with secure methods. User must use Oauth or Key pair authentication for Production use case.

NEW QUESTION # 278
A Snowpark Python application is failing intermittently with a 'net.snowflake.client.jdbc.SnowflakeSQLException: SQL execution error: Remote service internal error [Errorld: ...l' when calling 'df.collect()' on a DataFrame that results from joining multiple tables and applying a complex filter. The data volume is substantial, but within the warehouse's expected capacity. Which of the following actions are MOST likely to resolve this issue? (Select two)

A. Replace with 'df.toPandas(Y to improve memory management on the client side.
B. Break down the complex query into smaller, intermediate DataFrames and persist them using to avoid memory pressure during a single large query.
C. Implement retry logic around the 'df.collect()' call with exponential backoff, assuming the error is transient due to resource contention.
D. Switch to using the function with a raw SQL query instead of Snowpark DataFrame operations.
E. Increase the parameter to a higher value to prevent session timeouts.

Answer: B,C

Explanation:
Options B and C are the most likely to resolve the issue. Option B addresses potential memory pressure within Snowflake by breaking down the query and persisting intermediate results. Option C acknowledges that the error might be transient due to resource contention and implements retry logic. Increasing (A) is unlikely to solve a remote service internal error. 'df.toPandas()' (D) might exacerbate the problem by moving more data to the client. Using (E) is a workaround, but doesn't address the underlying problem within Snowpark and could reduce performance if not carefully optimized.

NEW QUESTION # 279
You have a Snowpark Python UDTF named that performs complex data transformations and you want to share it securely with another Snowflake account. Select ALL the necessary steps and considerations to properly share this UDTF using Snowflake Secure Data Sharing.

A. Grant SELECT privilege on the UDTF to the share.
B. Ensure the UDTF doesn't rely on any external packages or dependencies not available in the target account.
C. Create a share and grant usage on the database containing the 'process_data' UDTF to the share.
D. Create a secure UDTF and add it to share.
E. Grant OWNERSHIP privilege on the UDTF to the share.

Answer: A,B,C,D

Explanation:
To share a UDTF, you first create a share and grant USAGE on the database containing it (A). Then, you create the UDTF as SECURE to ensure data is protected (B). SELECT is needed to allow the share to actually use the function (C). It is important to make sure that the receiving account will be able to run the UDTF, so ensure all of the needed packages and dependendies are accounted for (D). GRANT OWNERSHIP would mean you would not be able to make changes to the function (E).
