Selected Answer: B
To eliminate excessive remote disk I/O (i.e., “spillage” of intermediate data to cloud storage), increase the size of the virtual warehouse. A larger warehouse provides more RAM and local SSD cache, so intermediate results stay in‑memory or on local disk rather than spilling to slower remote storage.
