8. Which three statements are true about the operation of a full-duplex Ethernet network?
1. There are no collisions in full-duplex mode.
2. A dedicated switch port is required for each full-duplex node.
3. Ethernet hub ports are preconfigured for full-duplex mode.
4. In a full-duplex environment, the host network card must check for the availability of the network media before transmitting.
5. The host network card and the switch port must be capable of operating in full-duplex mode.
9. Which of the following are types of flow control?
1. Buffering
2. Cut-through
3. Windowing
4. Congestion avoidance
10. What are two purposes for segmentation with a bridge?
1. To add more broadcast domains.
2. To create more collision domains.
3. To add more bandwidth for users.
4.To allow more broadcasts for users.
11. How does a host on an Ethernet LAN know when to transmit after a collision has occurred?
1. In a CSMA/CD collision domain, multiple stations can successfully transmit data simultaneously.
2. In a CSMA/CD collision domain, stations must wait until the media is not in use before transmitting.
3. You can improve the CSMA/CD network by adding more hubs.
4. After a collision, the station that detected the collision has first priority to resend the lost data.
5. After a collision, all stations run a random backoff algorithm. When the backoff delay period has expired, all stations have equal priority to transmit data.
12.
Which of the following types of connections can use full duplex?
1. Hub to hub
2. Switch to switch
3. Host to host
4. Switch to hub
5. Switch to host
13. Which fields are contained within an IEEE Ethernet frame header?
1. Source and destination MAC address
2. Source and destination network address
3. Source and destination MAC address and source and destination network address
4. FCS field
14. What type of RJ45 UTP cable do you use to connect a PC's COM port to a router or switch console port?
