IP Connectivity

Refer to the exhibit. What is one reason for poor performance on the network interface?

Question Image

  • A The interface is receiving excessive broadcast traffic.
  • B The bandwidth setting of the interface is misconfigured.
  • C The cable connection between the two devices is faulty.
  • D The interface is operating at a different speed than the connected device.
Explanation

A high number of input errors together with a matching high number of CRC errors indicates corrupted Ethernet frames being received, which is a classic sign of a physical-layer problem such as a bad cable, bad connector, or interference on the link. The exhibit does not show excessive broadcast traffic, and it shows the interface running at full duplex and 1000 Mbps, so broadcast load or an obvious speed-setting problem is not the best fit.
