최신 Snowflake Certification SPS-C01 무료샘플문제 (Q336-Q341):

질문 # 336
A Snowpark developer is using to create a Snowpark session. They want to ensure that the session uses a specific role and warehouse, but only if those parameters are not already defined in the Snowflake CLI configuration. Which of the following code snippets correctly implements this behavior?

정답：B

설명：
Option D offers a concise method where role and warehouse specified in the 'Session.builder' are only used if they aren't already defined in the environment or Snowflake CLI configurations. Snowflake gives precedence to the environment over the code when using the session builder. Options A does not take into account how Session.builder.configs would work in order to read the current CLI configurations. Option B overwrites even though the question state that if these parameters are already defined in Snowflake CLI configurations they should NOT be changed. Option C does not have complete Code. Option E is overly complicated.

질문 # 337
You're developing a Snowpark application that reads data from a Snowflake table, performs several transformations, and then writes the results back to a different table. You want to ensure that the entire process is executed as a single atomic transaction, even if it involves multiple Snowpark DataFrames and operations. Which of the following actions are required to achieve this transactional behavior?

A. Ensure that the target table for writing the results has the 'TRANSIENT' property set to 'TRUE'.
B. All Snowpark operations within a single session are automatically executed as a single atomic transaction by default; no additional configuration is required.
C. Leverage the 'CREATE OR REPLACE TABLE AS SELECT statement within a Stored Procedure called from your Snowpark code. All DML operations done as part of stored proc is transactional
D. Configure the Snowpark session with the parameter set to ' FALSE
E. Explicitly start a transaction using 'session.beginTransaction()' at the beginning of the Snowpark application and commit it using 'session.commitTransaction(Y at the end.

정답：B

설명：
Snowflake inherently provides transactional consistency. All operations within a single Snowpark session are automatically executed as a single atomic transaction by default. This is a core feature of Snowflake and doesn't require explicit transaction management in most common scenarios. Options A, B and C are incorrect as Snowflake handles transaction automatically. E describes a possible solution, however, it isn't required.

질문 # 338
You have a Snowpark DataFrame named 'employee_df in VS Code. You want to define a user-defined function (UDF) in Python that calculates the bonus for each employee based on their salary and performance rating. The UDF should take the salary (SALARY) and performance rating (PERFORMANCE RATING) as inputs and return the bonus amount. Assume you have already established a Snowpark session. Which code snippet accurately defines and registers a UDF named 'calculate_bonus' that can be applied to the 'employee_df DataFrame?

정답：C,E

설명：
Options A and B are both correct methods. Option A defines the Python function and then registers it as a UDF using session.udf.register' . It explicitly specifies the return type, input types, UDF name, and the 'replace=True' option to allow overwriting if the UDF already exists. Option B uses the guff decorator to directly register the function as a UDF, providing a more concise way to define and register UDFs. Option A is also valid as the user defined datatypes and name. Option C requires the snowflake-snowpark-python package (which is already installed via dependencies) and the 'fune argument is redundant. Option D is wrong as would remove the currently configured packages. Option E is incorrect because making the UDF permanent requires additional privileges and setup that aren't covered by default.

질문 # 339
You are tasked with optimizing the performance of a Snowpark application that uses a UDF to perform complex image processing. The UDF is currently registered using 'session.udf.registeff. You observe that the UDF execution is slow, particularly when processing large batches of images. What steps could you take to potentially improve the performance of this UDF execution? Select all that apply.

A. Ensure that the stage location specified during UDF registration is in the same region as the Snowflake account to minimize data transfer latency.
B. Ensure that the size of the zipped file containing the UDF's dependencies is as small as possible to speed up deployment.
C. Use session.clear_packages() to clear the session packages when deploying UDF.
D. Convert the UDF into a UDTF (User-Defined Table Function) if the image processing can benefit from row-by-row processing and aggregation.
E. Increase the warehouse size used for running the Snowpark application to provide more computational resources for the UDF execution.

정답：A,B,E

설명：
The correct answers are B, C, and E. Locating the stage in the same region minimizes latency (B). Smaller dependency files deploy faster (C). Larger warehouses provide more resources (E). Converting to a UDTF might not always improve performance, it depends on the nature of the image processing (A)' is not directly related to UDF performance optimization, it is used for session management and cleanup (D).

질문 # 340
You have created a Snowpark stored procedure in Python that accesses a Snowflake stage to read configuration files. To enhance security, you want to grant the stored procedure specific permissions to only read files from that stage, without granting broader account- level access. Which of the following approaches is the MOST secure and granular way to achieve this?

A. Grant the 'SELECT privilege on the stage to the role that owns the stored procedure.
B. Grant the 'USAGE privilege on the stage to the role that owns the stored procedure.
C. Create a stored procedure with 'EXECUTE AS CALLER and ensure the caller (user executing the procedure) has the necessary privileges.
D. Grant the 'READ privilege directly to the stored procedure using the 'ALTER PROCEDURE command.
E. Create a Snowflake custom role and grant the 'READ' privilege on the stage to this role, then grant this role to the stored procedure's owner.

정답：C

설명：
Using 'EXECUTE AS CALLER ensures the stored procedure executes with the privileges of the user calling it. This is the most secure and granular approach because you don't need to grant any specific privileges to the stored procedure itself. The user calling it must already have the necessary permissions to access the stage.
