NEW QUESTION # 71
Which command will unload data from a table into an external stage?

Answer: D

Explanation:
In Snowflake, the COPY INTO <location> command is used to unload (export) data from a Snowflake table to an external stage, such as an S3 bucket, Azure Blob Storage, or Google Cloud Storage. This command allows users to specify the format, file size, and other options for the data being unloaded, making it a flexible solution for exporting data from Snowflake to external storage solutions for further use or analysis.References:

NEW QUESTION # 73
Which Snowflake mechanism is used to limit the number of micro-partitions scanned by a query?

Answer: D

Explanation:
Query pruning in Snowflake is the mechanism used to limit the number of micro-partitions scanned by a query. By analyzing the filters and conditions applied in a query, Snowflake can skip over micro-partitions that do not contain relevant data, thereby reducing the amount of data processed and improving query performance. This technique is particularly effective for large datasets and is a key component of Snowflake's performance optimization features.
