Snowflake Certified SnowPro Specialty - Snowpark Sample Questions (Q215-Q220):

NEW QUESTION # 215
You're designing a Snowpark application to process large CSV files containing sensor data'. Each CSV file has millions of rows, and you need to calculate aggregate statistics (e.g., average, min, max) for specific sensor readings. The processing needs to be highly parallelized for performance. You have the following code snippet (incomplete):

Which of the following code snippets, when inserted at the ' ??? Add code here to calculate aggregate statistics ??? ' marker, would correctly calculate the average, minimum, and maximum readings for a column named 'sensor value' and return the result in a new Snowpark DataFrame?

Answer: B

Explanation:
Option C is correct. When calculating aggregate statistics across the entire DataFrame (i.e., without any grouping), you need to use groupBy(Y with no arguments. This effectively creates a single group for the entire dataset, allowing the aggregation functions to operate correctly. Option A is syntactically valid but misses the crucial 'groupBy()' step, resulting in an error. Option B is incorrect because the 'agg function expects a dictionary where keys are column names and values are aggregation function strings , not Snowpark functions themselves. It also does not return alias values. Options D and E are syntactically valid because you can use and "sensor_value" instead of , but they fail to include so give incorrect aggregations.

NEW QUESTION # 216
Consider the following Snowflake SQL statement intended to modify the properties of a Snowpark-optimized virtual warehouse named
'SNOWPARK_WH':

Which of the following statements accurately describe the expected outcome of executing this SQL statement?

A. The SQL statement will fail because the 'SCALING POLICY parameter cannot be set for Snowpark-optimized warehouses.
B. The SQL statement will execute successfully only if the user executing it has the 'MODIFY privilege on the 'SNOWPARK_WH' warehouse.
C. The SQL statement will execute successfully after checking if 'SNOWPARK_WH' is of Snowpark-optimized warehouse type, resizing the 'SNOWPARK_WH' warehouse to 'LARGE', setting the maximum number of clusters to 3, the minimum to 1, and enabling the 'ECONOMY' scaling policy.
D. The SQL statement will fail because you cannot modify 'WAREHOUSE_SIZE and 'MAX CLUSTER COUNT in a single SALTER WAREHOUSE statement.
E. The SQL statement will execute successfully, resizing the 'SNOWPARK WI-i' warehouse to 'LARGE', setting the maximum number of clusters to 3, the minimum to 1, and enabling the 'ECONOMY' scaling policy.

Answer: B,E

Explanation:
The 'ALTER WAREHOUSE statement is valid and will modify the specified properties. However, the user executing the statement must have the 'MODIFY privilege on the warehouse. The 'SCALING_POLICY parameter can be set for Snowpark-optimized warehouses, just like standard warehouses. All options can be specified in a single ALTER statement provided correct synax, the WAREHOUSE has been created and current User have correct privileges.

NEW QUESTION # 217
When using key pair authentication with Snowpark, what security best practices should you implement to protect your private key?
(Select all that apply)

A. Encrypt the private key at rest.
B. Store the private key in an environment variable or a secure secret management system (e.g., HashiCorp Vault, AWS Secrets Manager, Azure Key Vault).
C. Store the private key directly in the Snowpark code repository.
D. Regularly rotate the key pair.
E. Grant broad access to the environment variable containing the private key to all developers.

Answer: A,B,D

Explanation:
Storing the private key directly in the code repository (A) is a major security risk. Encrypting the private key at rest (B) provides an additional layer of security. Storing the private key in an environment variable or secure secret management system (C) is the recommended approach. Granting broad access (D) increases the risk of compromise. Regularly rotating the key pair (E) limits the impact if a key is compromised. Options B,C and E are the most secure ones.

NEW QUESTION # 218
Consider the following Snowpark Python code snippet designed to calculate a custom metric on financial data, using a vectorized UDF for performance. Identify potential performance bottlenecks and recommend optimization strategies.

Which of the following actions (may be more than one) would MOST likely improve the performance of this Snowpark application?

A. Repartition the 'data' DataFrame by 'ticker_symbol' before the 'groupBy' operation using to improve data locality.
B. Use to explicitly declare the Pandas dependency.
C. Change 'FloatType' to 'DoubleType' as it provides more precision.
D. Use before writing to the 'metric_table' , especially if the table is subsequently used downstream.
E. Ensure that the 'financial_data' table is clustered by 'ticker_symbor to optimize the 'groupBy' operation.

Answer: A,D,E

Explanation:
Clustering by 'ticker_symbol' significantly optimizes the 'groupBy' operation by organizing data physically for efficient retrieval. Caching the result before writing to a table is crucial if the intermediate result 'result' will be used multiple times, avoiding redundant computations. Repartitioning by 'ticker_symbol' before grouping helps distribute data evenly, improving parallelism and locality. While Pandas is generally available, explicitly declaring it might be necessary in certain isolated environments, so B can be considered a good practice, but not as impactful. Changing FloatType to DoubleType (C) will not lead to performnace improvement. It only changes precision level which is not required here.

NEW QUESTION # 219
Which of the following statements are correct regarding the authentication methods available when creating a Snowpark session?

A. Snowflake supports MFA(Multi-Factor Authentication) using Web Browser Authentication, which needs to be enabled at an account level.
B. OAuth with external Oauth providers (like Okta or Azure AD) is not supported in snowpark, and only username password can be used.
C. OAuth authentication requires pre-configuration in Snowflake and typically involves client IDs, client secrets, and refresh/access tokens.
D. Using username/password authentication is the most secure and recommended approach for production environments.
E. Key pair authentication uses a private key to establish a secure connection without needing to store passwords directly in the code.

Answer: A,C,E

Explanation:
Options B, C, and D are correct. OAuth provides a secure delegation mechanism. Key pair authentication is also a secure method, eliminating password storage in code. Snowflake Browser-Based MFA relies on web browser redirection. Option A is incorrect because username/password is generally less secure than key pair or OAuth. Option E is incorrect because External Oauth providers like Okta are Azure AD is supported for authentication using a federated OAuth flow.
