Question

Quizplus · Accepted Answer

When multiple servers are available and similarly skilled, a single line or a "first come, first serve" approach is best. This minimizes wait time and ensures fairness in service.

Answer: D
 In a maintenance queue system, the repair technicians are technically the customers, as they have to travel to the machines needing repair. The machines needing repair are the "servers" in this system.
