23. 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 network, performance degrades and excess collision are detected. What is the 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 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.
24. Which of the following statements are true regarding the user EXEC mode? (Choose two.)
• All router commands are available.
• Global configuration mode can be accessed by entering the enable command.
• A password can be entered to allow access to other modes.
• Interfaces and routing protocols can be configured.
• Only some aspects of the router configuration can be viewed.
25. Which command turns on a router interface?
• Router(config-if)# enable
• Router(config-if)# no down
• Router(config-if)# s0 active
• Router(config-if)# interface up
