In Central Dispatch drag and drop, what happens if a higher priority task is dragged on top of a lower priority task?

• A. Dynamic scheduling assigns the higher priority task and reassigns the lower priority task
• B. The higher priority task is ignored
• C. A warning is displayed and no change occurs
• D. Both tasks are swapped without reassignment

Answer: (A)

Dragging a higher-priority task onto a lower-priority one triggers the scheduling engine to re-optimize the plan. Central Dispatch, with dynamic scheduling, evaluates the new priority and reallocates work accordingly. The higher-priority task is assigned to the most suitable available resource, and the lower-priority task is reassigned to another resource or moved to a different time slot, updating the queue and start times as needed. This automatic reassignment ensures urgent work is addressed promptly rather than being ignored or left unchanged, and it avoids a simple swap that leaves tasks unmoved.
