A high utilization factor means that the server is very busy and the queue is likely to be longer. This will result in longer waiting times, reduced customer satisfaction, and decreased system performance. On the other hand, a low utilization factor means that the server is not being fully utilized and there may be idle time. This can result in improved efficiency and faster service. Therefore, II is true, while I and III are false.
