最新的 Snowflake Certification SPS-C01 免費考試真題:

1. You're building a Snowpark Python application that processes sensor data from various devices. The data arrives as a stream of JSON objects, each containing the device ID, timestamp, and sensor readings. You want to use a Streamlit application to visualize near real- time aggregates on the data'. You're aiming to create a Snowpark DataFrame from this data, perform transformations, and then serve this DataFrame to Streamlit. Which of the following approaches concerning creating the initial DataFrame from JSON data is generally the MOST efficient and scalable for handling such a stream of data?

A) Use Snowflake's Kafka connector to ingest the JSON data directly into a Snowflake table, and then create a Snowpark DataFrame from that table using 'session.table()'.
B) Utilize Snowpipe with auto-ingest configured to load the JSON data into a raw data Snowflake table, and subsequently, establish a Snowpark DataFrame using 'session.table('raw_data_table')'. You can then apply necessary transformations using Snowpark.
C) Iteratively append each JSON object to a Python list, then create a Snowpark DataFrame from the list using 'session.createDataFrame(list_of_json_objectsy.
D) Read the JSON data directly from the stream into a Pandas DataFrame using , then convert the Pandas DataFrame to a Snowpark DataFrame using 'session.createDataFrame(pandas_df)'.
E) Write each incoming JSON object to a temporary file in cloud storage (e.g., AWS S3 or Azure Blob Storage) and then periodically use 'session.read.json()' to create a Snowpark DataFrame from the files.

2. You have a Snowpark DataFrame containing data to be loaded into a Snowflake table You want to use the 'merge' operation to update existing records and insert new records. The has a column (BOOLEAN) that indicates whether a record should be updated (TRUE) or inserted (FALSE) if it doesn't already exist. Which of the following SQL expressions correctly implement this logic within the 'merge' operation's 'WHEN MATCHED' and 'WHEN NOT MATCHED' clauses?

A) WHEN MATCHED THEN UPDATE SET target_table.columnl = staging_df.columnl WHEN NOT MATCHED THEN INSERT (columni) VALUES (staging_df.columnl )
B) WHEN MATCHED AND = TRUE THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED AND = FALSE THEN INSERT (columni) VALUES (staging_df.columnl)
C) WHEN MATCHED AND THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED AND NOT THEN INSERT (columni) VALUES (staging_df.columnl)
D) WHEN MATCHED AND = TRUE THEN UPDATE SET target_table.columnl = staging_df.columnl WHEN NOT MATCHED AND = FALSE THEN INSERT (columni) VALUES (staging_df.columnl)
E) WHEN MATCHED THEN UPDATE SET columni = staging_df.columnl WHEN NOT MATCHED THEN INSERT (columni) VALUES (staging_df.columnl)

3. You have a Snowpark application that processes sensitive data'. To enhance security, you want to use key pair authentication and ensure that the private key is never exposed in plain text within the application or logs. Which of the following strategies offers the most robust protection against accidental key exposure, even in the event of a security breach of the application server itself?

A) Use a dedicated Hardware Security Module (HSM) or a cloud-based key management service (e.g., AWS KMS, Azure Key Vault) to store and manage the private key. Configure the Snowpark application to retrieve the key only when needed and never store it locally.
B) Store the private key encrypted using AES encryption with a key derived from a passphrase. Prompt the user for the passphrase each time the application starts.
C) Store the private key encrypted with a symmetric key. Store the symmetric key in a separate environment variable.
D) Store the private key in an environment variable on the application server, ensuring that only the application user has read access.
E) Store the private key in an encrypted file with restricted access, decrypting it only during session creation and overwriting the memory location immediately afterwards.

4. A Snowpark application connects to Snowflake using key pair authentication. After several successful executions, the application starts failing with authentication errors. You suspect an issue with the private key. Considering best practices for security and troubleshooting, which of the following actions should you take FIRST to diagnose and resolve the problem?

A) Restart the Snowpark application server to refresh the session and clear any cached credentials.
B) Check the Snowflake login history in ACCOUNT _ USAGE view to identify the specific error message and the IP address from which the failed login attempts originated. Use new authtype and password.
C) Immediately revoke the user's access to Snowflake and create a new user with a different private key.
D) Verify that the private key file exists at the specified path in the Snowpark application configuration and that the user running the application has read permissions on the file.
E) Rotate the public/private key pair immediately and update the Snowpark application with the new private key. Generate new username and password.

5. You are developing a Snowpark application in Python to perform sentiment analysis on customer reviews stored in a Snowflake table named 'CUSTOMER_REVIEWS. The table has columns 'REVIEW ONT), 'REVIEW TEXT (VARCHAR), and 'SENTIMENT SCORE (FLOAT). You want to define a UDF using Snowpark that leverages a pre-trained sentiment analysis model from the 'nltk' library (already uploaded to a stage). The UDF should take 'REVIEW TEXT' as input and return the sentiment score. Which of the following code snippets will correctly define and register the UDF, ensuring it's accessible for use in Snowpark DataFrames, taking into account potential serialization issues with 'nltk' models?

A)

B)

C)

D)

E)
