4070. 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

4071. 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

4072. 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.

4073. Which statement is true about the operation of a full-duplex Ethernet network, which is being used in the LAN?

1. Ethernet hub ports are preconfigured for full-duplex mode.In a full-duplex environment
2. the host network card must check for the availability of the network media before transmittingThe host network card and the switch port must be capable of operating in full-duplex mode.
3. None of the above

4074. On a half-duplex Ethernet LAN, two hosts attempt to send data simultaneously, resulting in a collision. Following this collision, what will the hosts do?

1. The jam signal indicates that the collision has been cleared.
2. An electrical pulse indicates that the collision has cleared.
3. The destination host sends a request to the source for retransmission.
4. The hosts will attempt to resume transmission after a time delay has expired.

4075. You want to influence the root bridge selection within the LAN. Which value is used by spanning tree protocol to elect a root bridge?

1. Amount of RAM
2. IOS Version
3. MAC Address
4. Speed of the links

4076. What is a characteristic of “store and forward” switching?

1. The switch receives the complete frame before beginning to forward it.
2. None of the above
3. The switch checks the destination address upon receipt of headers.
4. Latency fluctuates regardless of frame size.

4077. Which of the following are true of Ethernet technology?

1. Hosts use a logical ring topology.
2. Hosts must wait for an electronic signal to transfer data.
3. Hosts use a logical bus topology
4. Hosts are directly connected to a wiring concentrator called a MSAU.

4078. Which of the following devices can the network administrator use to segment the LAN?

1. Repeaters
2. Switches
3. None of the above
4. Hubs

4079. University has a small campus where 25 faculty members are located. The faculty offices and student computers are currently on the same network. The faculty is concerned about students being able to capture packets going across the network and obtain sensitive material. What could a network administrator do to protect faculty network traffic from student connections?

1. Power down the switches that connect to faculty computers when they are not in use
2. Install anti-virus software on the student computers.
3. Put the faculty computers in a separate VLAN.
4. Remove the student computers from the network and put them on a peer-to-peer network
