A network technician is attempting to connect an older device to a FastEthernet port on a Cisco switch. The technician has manually configured the device to full-duplex mode in order to enhance the network performance of the device. However, when the device is attached to the network, performance degrades and excessive collisions are detected on the switch. What is the likely cause of this problem?

A network technician is attempting to connect an older device to a FastEthernet port on a Cisco switch. The technician has manually configured the device to full-duplex mode in order to enhance the network performance of the device. However, when the device is attached to the network, performance degrades and excessive collisions are detected on the switch. What is the likely cause of this problem?
- The host is configured in a different subnet from the subnet of the switch.
- There is a duplex mismatch between the device and switch port.
- The switch port is running at a different speed from the speed of the device NIC.
- The host has been configured with a default gateway that is different from that of the switch.
Explanation: Duplex mismatch is one of the most common causes of performance issues on 10/100 Mbps Ethernet links. It occurs when one port on the link operates at half-duplex while the other port operates at full-duplex
