Suggested answer: B, D

Explanation:

Two key metrics in Snowflake's Query Profile that provide insights for performance improvement are:

Remote Disk IO: This measures the time the query spends waiting on remote disk access, indicating potential performance issues related to I/O bottlenecks.

Pruning: This metric reflects how effectively Snowflake's micro-partition pruning is reducing the data scanned. Better pruning (more partitions excluded) leads to faster query performance, as fewer micro-partitions need to be processed.

These metrics are essential for identifying and addressing inefficiencies in data retrieval and storage access, optimizing overall query performance.
