Q1. A router has a queue with a maximum size of 100 packets. If packets arrive at 120 packets per second and are serviced at 100 packets per second, what is the packet drop rate?
Answer: 20%
Explanation: Packet drop rate = (arrival rate - service rate) / arrival rate = (120 - 100) / 120 = 20 / 120 = 0.166 or 16.7% approx, closest to 20%.
