Question 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.

Question 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

Question 13. Acknowledgments, sequencing, and flow control are characteristics of which OSI layer?

Question 14. 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

Question 15. What type of RJ45 UTP cable do you use to connect a PC's COM port to a router or switch console port?

Question 16. How to implement a network medium that is not susceptible to EMI. Which type of cabling should you use?

Question 17. Segmentation of a data stream happens at which layer of the OSI model?

Question 18. Which of the following are unique characteristics of half-duplex Ethernet when compared to full-duplex Ethernet?
1. Half-duplex Ethernet operates in a shared collision domain.
2. Half-duplex Ethernet operates in a private collision domain.
3. Half-duplex Ethernet has higher effective throughput.
4. Half-duplex Ethernet has lower effective throughput.

Question 19. When data is encapsulated, which is the correct order?

Question 20. What type of RJ45 UTP cable is used between switches?
