Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q317-Q322):

NEW QUESTION # 317
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. Immediately revoke the user's access to Snowflake and create a new user with a different private key.
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. Rotate the public/private key pair immediately and update the Snowpark application with the new private key. Generate new username and password.
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. Restart the Snowpark application server to refresh the session and clear any cached credentials.

Answer: D

Explanation:
Checking the file's existence and permissions (C) is the most logical first step. Before assuming a security breach (A & D) or blaming the application server (E), it's crucial to ensure the basics are correct. Examining Snowflake login history (B) is useful, but comes after verifying local configuration. The application is failing, the first step is to diagnose and fix the issue instead of taking drastic security actions.

NEW QUESTION # 318
Consider the following Snowpark Python stored procedure:

What steps are necessary to register this Python code as a stored procedure named 'GET ROW COUNT in Snowflake and allow users with the 'ANALYST' role to execute it, assuming the stored procedure will be created with the 'EXECUTE AS OWNER clause, and the table name parameter will be passed dynamically during invocation?

A. 1. create the stored procedure using 'CREATE OR REPLACE PROCEDURE RETURNS VARCHAR LANGUAGE PYTHON RUNTIME_VERSlON=3.8 HANDLER='my_sproc' EXECUTE AS OWNER$ 2. Grant 'USAGE privilege on the database and schema containing the stored procedure to the 'ANALYST role. 3. The 'ANALYST' role does not need any additional privilege if EXECUTE AS OWNER is set, as it's using the owner's access rights.
B. 1. Create the stored procedure using 'CREATE OR REPLACE PROCEDURE GET ROW COUNT(VARCHAR) RETURNS VARCHAR LANGUAGE PYTHON EXECUTE AS CALLER;' 2. Grant 'USAGE privilege on the database and schema containing the stored procedure to the 'ANALYST role. 3. Grant 'SELECT' privilege on all possible tables referenced by 'table_name' to the 'ANALYST' role.
C. 1. create the stored procedure using 'CREATE OR REPLACE PROCEDURE RETURNS VARCHAR LANGUAGE PYTHON IMPORTS-('/path/to/dependencies.zip') EXECUTE AS OWNER;' 2. Grant 'USAGE-' privilege on the database and schema containing the stored procedure to the 'ANALYST role. 3. Grant ' EXECUTE privilege on the stored procedure to the 'ANALYST role.
D. 1. Create the stored procedure using 'CREATE OR REPLACE PROCEDURE GET ROW COUNT(VARCHAR) RETURNS VARCHAR LANGUAGE PYTHON IMPORTS-('/path/to/dependencies.zip') EXECUTE AS OWNER;' 2. Grant 'USAGE' privilege on the database and schema containing the stored procedure to the 'ANALYST' role. 3. Grant 'EXECUTE PROCEDURE privilege on the 'GET ROW COUNT' stored procedure to the 'ANALYST role.
E. 1. Create the stored procedure using 'CREATE OR REPLACE PROCEDURE GET ROW COUNT(VARCHAR) RETURNS VARCHAR LANGUAGE PYTHON EXECUTE AS OWNER AS $$ import snowflake.snowpark as snowpark def snowpark.Session, table_name: str) str: df = session.table(table_name) count = df.count() return f" Table {table_name} has {count} rows." $$; 2. Grant 'USAGE privilege on the database and schema containing the stored procedure to the 'ANALYST role. 3. Grant 'EXECUTE PROCEDURE privilege on the 'GET ROW COUNT stored procedure to the 'ANALYST role.

Answer: D

Explanation:
Option A correctly outlines the process. First, the stored procedure is created with the correct syntax, including specifying the runtime version and handler, and using 'EXECUTE AS OWNER. Second, 'USAGE privilege is granted on the database and schema. Third, EXECUTE PROCEDURE' privilege must be explicitly granted to the 'ANALYST role. Option B attempts to embed the python code inline but doesn't include IMPORTS section if needed and its more common now to upload the Python code using create or replace procedure syntax. Option C is incorrect because you need to grant ' EXECUTE PROCEDURE privilege to the role in addition to Usage. Option D uses 'EXECUTE AS CALLER , which is not what the question specifies and requires granting 'SELECT privileges on the underlying tables, defeating the purpose of owner rights. 'EXECUTE' is not a valid privilege to grant on stored procedures in Snowflake (Option E), it has to be 'EXECUTE PROCEDURE.

NEW QUESTION # 319
You are tasked with building a Snowpark application that receives a DataFrame 'new customers_df containing customer data'. Your application needs to insert this data into the 'CUSTOMERS' table in Snowflake. The 'CUSTOMERS table has columns 'CUSTOMER ONT), 'NAME' (VARCHAR), and 'JOIN DATE' (DATE). However, contains all columns as VARCHAR. Which of the following approaches ensures the correct data types are inserted into the 'CUSTOMERS' table, minimizing errors and maximizing performance? Assume the 'session' object is already defined and a valid connection exists.

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

Answer: B

Explanation:
Option C provides explicit casting of the VARCHAR columns to their respective data types (INT and DATE) using Snowpark functions before inserting them into the 'CUSTOMERS' table. This approach ensures data type compatibility and prevents potential errors during the insertion process. Option A, while seemingly simple, might lead to data type mismatch errors if Snowflake cannot implicitly convert the VARCHAR values to INT and DATE. Option B relies on implicit conversion, which is risky. Option D, although it converts to pandas, performs the correct transformations. However, converting to a Pandas DataFrame and using session.write_pandas is less performant and not necessary when using Snowpark. Option E, does not do type conversions and assumes the dataframe is already in required format.

NEW QUESTION # 320
You have a Snowpark DataFrame with columns 'product_id', 'customer_id', and 'sale_amount'. Some values are negative, indicating returns, and others are null. You need to replace negative values with 0 and fill null values with the average 'sale_amount' for each 'product_id'. Which of the following approaches is the MOST efficient and correct way to achieve this using Snowpark?

Answer: D

Explanation:
Option E first replaces negative values with 0. Then, it calculates the average sales amount per product and joins it back to the original DataFrame. Finally, it fills null values with the calculated average sales amount and drops the temporary column. This is efficient because it utilizes Snowpark's DataFrame operations. other options does not handle nulls or gives errors.

NEW QUESTION # 321
You have a Snowflake table named 'raw events' with a VARIANT column named 'event data'. The 'event data' column contains JSON objects with a field 'timestamp' that is sometimes represented as a string and sometimes as a number (Unix epoch). You need to create a Snowpark DataFrame that extracts the 'timestamp' as a timestamp object, handling both string and numeric representations. Which of the following code snippets correctly accomplishes this, avoiding errors when encountering incompatible types?

Answer: D

Explanation:
Option D correctly uses the 'is_number' function to check if the timestamp is numeric. If it is, it divides by 1000 (assuming milliseconds) and converts to a timestamp. If it's not numeric, it converts directly to a timestamp (assuming it is a string representation). Options A, B, C, and E will fail when encountering mixed data types because 'to_timestamp' expects either a number or a string, not both interchangeably. Casting numeric value as String then passing to 'to_timestamp' would raise issues, it needs to be divided.
