  2. Workload Isolation intermediate Multiple choice

    A lakehouse platform runs interactive BI on its own compute cluster and pipelines on another, and both are sized comfortably. Every Tuesday and Wednesday queries against the ten largest tables run 3 to 6 times slower on both clusters at once, then recover by Thursday. Table maintenance - compaction and snapshot expiry - is submitted as low-priority work on the pipeline cluster. Which change fixes it?
