Network Troubleshooting第 95 / 100 题
A server's throughput is far below the link's rated speed, and interface counters show many output drops during peak traffic. What is the likely cause?
a.A DNS misconfiguration
b.An incorrect default gateway
c.A duplicate IP address
d.Congestion causing the interface queue to overflow
解析
Output drops during peak traffic indicate the interface queue is overflowing due to congestion, so packets are discarded when buffers fill. QoS, increased capacity, or traffic shaping can relieve it. The correlation with peak load confirms congestion rather than a config error.
