Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q106-Q111):

NEW QUESTION # 106
Consider the following Snowpark Python code snippet:

A. The code will fail because there is no call to or on the 'result_df dataframe and Snowflake performs lazy evaluation.
B. This code will ovemrite the table if it already exists.
C.
D. This code will fail because is not a valid method for Snowpark DataFrames.
E. The 'result_df DataFrame will be persisted to the 'AGGREGATED SALES table in the default schema of the user running the code.

Answer: B,E

Explanation:
' will indeed overwrite the table if it exists. When a schema is not explicitly specified, Snowpark defaults to the schema of the user's current session for table creation. No explicit call to an action like 'collect()' or show()' is needed to trigger execution, as is an action itself. is a valid operation to persist DataFrames as tables in Snowpark. The table name does not strictly need to be fully qualified unless targeting a schema different from the user's default.

NEW QUESTION # 107
You are building a Snowpark application to process sensitive data'. To enhance security, you want to leverage ephemeral sessions. Which configurations, passed to 'snowpark.Session.builder.configS , are required and sufficient to create an ephemeral session? Assume your Snowflake environment is properly configured to allow ephemeral sessions.

A. Only setting the 'role' parameter to a role with appropriate privileges.
B. Setting the 'role' parameter to a role with appropriate privileges and 'warehouse'.
C. Ephemeral sessions do not have specific configurations; they are automatically created by Snowflake when the application connects.
D. Setting the 'role' parameter to a role with appropriate privileges and 'database' and 'schema'.
E. Setting the 'role' parameter to a role with appropriate privileges, 'database', 'schema', and 'warehouse'.

Answer: E

Explanation:
Ephemeral sessions in Snowflake require that you specify a 'role', 'database', 'schema', and 'warehouse'. These parameters define the context within which the session will operate. Without these parameters, the session cannot be properly established. Although option A set role which is important for setting the context but it is insufficient. Ephemeral sessions are not automatic and require proper configuration.

NEW QUESTION # 108
You have a Snowpark DataFrame 'employees df representing employee data'. You need to update the 'salary' column for employees in the 'Sales' department by applying a 10% increase. Which of the following Snowpark code snippets correctly performs this update? Assume a Snowflake table named 'employees' exists and 'employees df' is correctly created from it.

A. Option D
B. Option E
C. Option B
D. Option A
E. Option C

Answer: B,E

Explanation:
Options C and E are correct. Snowpark does not have an 'update' method directly on DataFrames like some other Spark-based DataFrame implementations. The correct way to update the data is to use 'with_column' along with 'when' and 'otherwise' from 'snowflake.snowpark.functions' to conditionally update the 'salary' column based on the 'department'. The part is crucial to persist the changes back to the Snowflake table after the transformation. Option C imports the required functions using 'from snowflake.snowpark.functions import when, cor and Option E directly uses the dataframe to invoke function and column names. Option A and D are incorrect because Snowpark does not provide an 'update' or direct save after filtering like that for this type of update. Option B is also incorrect because the update function doesn't exist on dataframes.

NEW QUESTION # 109
You are developing a Snowpark application to load data into a Snowflake table named 'SALES DATA. The DataFrame 'sales_df contains new sales records. You need to insert these records into 'SALES DATA. Which of the following Snowpark DataFrame methods will efficiently perform this operation, considering potential data type mismatches between the DataFrame and the target table? Assume no explicit schema definition is necessary.

A. Option D
B. Option A
C. Option E
D. Option C
E. Option B

Answer: E

Explanation:
The method directly inserts the DataFrame's data into the specified Snowflake table. Snowpark implicitly handles data type conversions where possible. is generally for creating new tables. is for loading data from files in stages, and 'write_pandas' method requires pandas DataFrame and session object. Using is inefficient as it collects all the data into the driver and then inserts and can cause memory issues.

NEW QUESTION # 110
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. 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.
B. Store all connection parameters as a JSON string in a single environment variable and parse it within the Snowpark application.
C. Manually retrieve each parameter using 'os.environ.get()' and pass them directly into the 'Session.builder.configs()' method.
D. 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.
E. 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.

Answer: E

Explanation:
Option E, 'Session.builder.getOrCreate(V , is the most concise and recommended approach. It automatically retrieves connection parameters from standard environment variables (e.g., SNOWFLAKE_USER, SNOWFLAKE_PASSWORD, SNOWFLAKE_ACCOUNT). This simplifies the code and reduces the risk of errors. Option A is verbose and prone to errors. Option B introduces unnecessary complexity and parsing. Option C involves the classic Snowflake connector, which is not the recommended way with Snowpark for Python. Option D involves snowCLl profiles and is not using Environment Variables.
