NEW QUESTION # 540
Which Snowflake tool is recommended for data batch processing?
Answer: B
Explanation:
For data batch processing in Snowflake, the recommended tool is:
B . SnowSQL: SnowSQL is the command-line client for Snowflake. It allows for executing SQL queries, scripts, and managing database objects. It's particularly suitable for batch processing tasks due to its ability to run SQL scripts that can execute multiple commands or queries in sequence, making it ideal for automated or scheduled tasks that require bulk data operations.
SnowSQL provides a flexible and powerful way to interact with Snowflake, supporting operations such as loading and unloading data, executing complex queries, and managing Snowflake objects from the command line or through scripts.

NEW QUESTION # 542
Which of the following are best practice recommendations that should be considered when loading data into Snowflake? (Select TWO).
Answer: A,D
Explanation:
When loading data into Snowflake, it is recommended to:
C . Load files that are approximately 100-250 MB (or larger): This size is optimal for parallel processing and can help to maximize throughput. Smaller files can lead to overhead that outweighs the actual data processing time.
D . Avoid using embedded characters such as commas for numeric data types: Embedded characters can cause issues during data loading as they may be interpreted incorrectly. It's best to clean the data of such characters to ensure accurate and efficient data loading.
These best practices are designed to optimize the data loading process, ensuring that data is loaded quickly and accurately into Snowflake.
