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

1. You have a Snowpark application that reads data from a large Snowflake table and performs several transformations. During testing, you observe that the application's performance is inconsistent, with some runs taking significantly longer than others, even with the same input data'. You suspect that data locality might be a contributing factor. What steps can you take within your Snowpark application to investigate and potentially improve data locality and performance consistency?

A) Implement caching using , combined with a targeted 'repartition()' to ensure that frequently accessed data is readily available in memory close to the processing nodes.
B) Enable Snowflake's automatic clustering on the underlying table if it's not already enabled. This will physically organize the data on disk based on the clustering key.
C) Disable Snowflake's result cache. This ensures that the application always reads the most recent data from disk, regardless of performance impact.
D) Use to redistribute the data across the cluster based on a relevant key. This can improve data locality for subsequent operations.
E) Ensure the Snowpark session is configured with a large enough warehouse size to minimize data spilling to disk.

2. You are tasked with creating a Snowpark session that utilizes a specific Snowflake warehouse for all operations. Which of the following code snippets BEST demonstrates how to correctly specify the 'warehouse' parameter when creating a session using snowpark.Session.builder.configs'?

A)

B)

C)

D)

E)

3. 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.

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

5. You are developing a Snowpark Python application that processes streaming data from an external source. The application requires near real-time insights and involves complex data transformations. However, you are observing high latency in the data processing pipeline. Which of the following optimization techniques would be MOST relevant to address this issue in the context of Snowpark and Snowflake?

A) Utilize Snowflake Streams and Tasks to incrementally transform and process the data within Snowflake, leveraging Snowpark UDFs for complex calculations.
B) Write the streaming data directly to external stages and query it using Snowpark DataFrames with external table access.
C) Implement Snowpipe to continuously load the streaming data into Snowflake tables and use Snowpark DataFrames to process the data incrementally.
D) Increase the virtual warehouse size to an extremely large instance to handle the high volume of streaming data.
E) Pre-aggregate the streaming data using an external stream processing engine (e.g., Apache Kafka, Apache Flink) before loading it into Snowflake.
