20. A network technician is attempting to add an older workstation to a Cisco switched LAN.
The technician has manually configured the workstation to full-duplex mode in order to enhance
the network performance of the workstation. However, when the device is attached to the

problem?
The host is configured in a different subnet from the subnet of the switch.
There is a duplex mismatch between the workstation and switch port.
The switch port is running at a different speed from the speed of the workstation NIC.
The host has been configured with a default gateway that is different from that of the switch.
21.

address of the router LAN interface. A network administrator is using a laptop to configure
switch X with a default gateway. Assuming that the switch IP address is 192.168.5.147/24, what
command will the administrator use to assign a default gateway to the switch?
X(config)# ip default-gateway 192.168.5.254
