When reviewing a query profile, what is a symptom that a query is too large to fit into the memory?
A symptom that a query is too large to fit into memory is that it starts spilling to remote storage. This occurs when the available memory is not sufficient to hold intermediate results during the query execution, causing the query processing engine to spill data first to local disk and then to remote storage if local space is insufficient. Spilling to remote storage is indicative of memory limitations during query processing.
For some operations (e.g. duplicate elimination for a huge data set), the amount of memory available for the compute resources used to execute the operation might not be sufficient to hold intermediate results. As a result, the query processing engine will start *spilling* the data to local disk. If the local disk space is not sufficient, the spilled data is then saved to remote disks. https://docs.snowflake.com/en/user-guide/ui-query-profile.html#queries-too-large-to-fit-in-memory
I agree, I think having all partitions scanned just means you might want to set up a cluster key.

Answer should be D

I agree with Answer D, if query spilling happens , query processing engine start saving the data to local disk if this is not sufficient then it start saving the data to remote disk, this process significantly impact query performance, the solution is use larger size warehouse.
Answer should be D
as per documentaion
as per the document it will spill to local storage and if it fills then dumped into Remote storage
As a result, the query processing engine will start spilling the data to local disk. If the local disk space is not sufficient, the spilled data is then saved to remote disks.
D is correct
