What column type does a Kafka connector store formatted information in a single column?

Correct Answer:D
The Kafka connector stores formatted information in a single column of type VARIANT. This column type is used to store semi-structured data like JSON or Avro, which allows for flexibility in the data structure

While unloading data into a stage, how can the user ensure that the output will be a single file?

Correct Answer:B
To ensure that the output will be a single file when unloading data into a stage, you should use the COPY option SINGLE=TRUE. This option specifies that the result of the COPY INTO command should be written to a single file, rather than multiple files.

A user has semi-structured data to load into Snowflake but is not sure what types of operations will need to be performed on the data. Based on this situation, what type of column does Snowflake recommend be used?

Correct Answer:D
When dealing with semi-structured data in Snowflake, and the specific types of operations to be performed on the data are not yet determined, Snowflake recommends using the VARIANT data type. The VARIANT type is highly flexible and capable of storing data in multiple formats, including JSON, AVRO, BSON, and more, within a single column. This flexibility allows users to perform various operations on the data, including querying and manipulation of nested data structures without predefined schemas.

When should a multi-cluster warehouse be used in auto-scaling mode?

Correct Answer:D
A multi-cluster warehouse should be used in auto-scaling mode when there is a need to handle a large number of concurrent queries. Auto-scaling allows Snowflake to automatically add or remove compute clusters to balance the load, ensuring that performance remains consistent during varying levels of demand

A virtual warehouse is created using the following command:
Create warehouse my_WH with warehouse_size = MEDIUM min_cluster_count = 1
max_cluster_count = 1
auto_suspend = 60 auto_resume = true;
The image below is a graphical representation of the warehouse utilization across two days.

What action should be taken to address this situation?

Correct Answer:C
The graphical representation of warehouse utilization indicates periods of significant queuing, suggesting that the current single cluster cannot efficiently handle all incoming queries. Configuring the warehouse to a multi-cluster warehouse will distribute the load among multiple clusters, reducing queuing times and improving overall performance1.
