Which Snowflake table type is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is dropped at the end of the session?
- A. Temporary
- B. User
- C. Transient
- D. Local
Answer: A
Explanation:
In Snowflake, a Temporary table is a type of table that is only visible to the user who creates it, can have the same name as permanent tables in the same schema, and is automatically dropped at the end of the session in which it was created. Temporary tables are designed for transient data processing needs, where data is needed for the duration of a specific task or session but not beyond. Since they are automatically cleaned up at the end of the session, they help manage storage usage efficiently and ensure that sensitive data is not inadvertently persisted.

NEW QUESTION # 135
Which type of workload is recommended for Snowpark-optimized virtual warehouses?
- A. Workloads that are queried with small table scans and selective filters
- B. Workloads that have large memory requirements
- C. Workloads with unpredictable data volumes for each query
- D. Workloads with ad hoc analytics
Answer: B
Explanation:
Snowpark-optimized virtual warehouses in Snowflake are designed to efficiently handle workloads with large memory requirements. Snowpark is a developer framework that allows users to write code in languages like Scala, Java, and Python to process data in Snowflake. Given the nature of these programming languages and the types of data processing tasks they are typically used for, having a virtual warehouse that can efficiently manage large memory-intensive operations is crucial.
Understanding Snowpark-Optimized Virtual Warehouses:
Snowpark allows developers to build complex data pipelines and applications within Snowflake using familiar programming languages.
These virtual warehouses are optimized to handle the execution of Snowpark workloads, which often involve large datasets and memory-intensive operations.
Large Memory Requirements:
Workloads with large memory requirements include data transformations, machine learning model training, and advanced analytics.
These operations often need to process significant amounts of data in memory to perform efficiently.
Snowpark-optimized virtual warehouses are configured to provide the necessary memory resources to support these tasks, ensuring optimal performance and scalability.
Other Considerations:
While Snowpark can handle other types of workloads, its optimization for large memory tasks makes it particularly suitable for scenarios where data processing needs to be done in-memory.
Snowflake's ability to scale compute resources dynamically also plays a role in efficiently managing large memory workloads, ensuring that performance is maintained even as data volumes grow.
