4040. The LAN needs are expanding at the corporate office, which is quickly growing. You are instructed to enlarge the area covered by a single LAN segment on the network. Which of the following are layer 1 devices that you can use?

1. A router
2. A hub
3. A switch
4. A network adapter card

4041. When a switch port is used as a VLAN trunk, which of the following trunk modes are valid?

1. Auto
2. Blocking
3. Ready
4. None of the above

4042. Which of the following can lead to the contribution of LAN traffic congestion?

1. Full duplex operation
2. Multicasting
3. None of the above
4. Too many hosts in a broadcast domain

4043. Some of the older switches store the entire frame before forwarding it to the destination. What is the effect on network performance of configuring a switch to do this?

1. Increased latency
2. None of the above
3. Decreased latency
4. Filtering of collision fragments only

4044. A Ethernet switch receives a unicast frame with a destination MAC that is listed in the switch table. What will this switch do with the frame?

1. The switch will forward the frame to all ports except the port on which it was received
2. The switch will return a copy of the frame out the source port
3. The switch will forward the frame to a specific port
4. The switch will remove the destination MAC from the switch table

4045. Which of the following statements correctly describe the differences between half-duplex and full-duplex Ethernet?

1. None of the above
2. A full-duplex Ethernet card allows 20Mbps for data transmission.
3. Half-duplex Ethernet uses a loopback circuit to detect collisions.
4. Full-duplex Ethernet uses CSMA/CD to prevent collisions.

4046. Which statements describe the operation of the CSMA/CD access method, which is in use on the network?

1. After a collision
2. the station that detected the collision has first priority to resend the lost dataIn a CSMA/CD collision domain
3. stations must wait until the media is not in use before transmittingIn a CSMA/CD collision domain
4. multiple stations can successfully transmit data simultaneously.The use of hubs to enlarge the size of collision domains is one way to improve the operation of the CSMA/CD access method

4047. What kind of cable should be used to establish a trunked line between two Catalyst switches?

1. An auxiliary cable
2. A cross-over cable
3. An EIA/TIA-232 serial cable
4. A straight-through cable

4048. An administrator issues the show ip interface s0/0 command and the output displays that interface Serial0/0 is up, line protocol is up What does "line protocol is up" specifically indicate about the interface?

1. Keepalives are being received on the interface
2. The cable is attached properly.
3. CDP has discovered the connected device
4. A carrier detect signal has been received from the connected device

4049. Which command will set the default gateway to 192.168.12.1 on a Cisco switch named 3?

1. 3(config)# ip route-default 192.168.12.1
2. 3(config)# ip default-network 192.168.12.1
3. 3(config)# ip default-gateway 192.168.12.1
4. 3(config)# ip route 192.168.12.1 0.0.0.0
