Section 1.2.1
9. What advantage does cut-through switching have over store-and-forward?
10. A switch receives a frame and the destination MAC address is not contained in the MAC address
table. What does the switch do?
11. A PC is connected to a switch and the PC issues a DHCP broadcast to find a DHCP server. To which
port does the switch forward the broadcast?
12. What information is added to the switch table from incoming frames?
13. What are the functions of a Layer 2 switch?

17. What does the term "port density" mean when describing an Ethernet switch?
18. A network administrator would like to increase the throughput of the LAN. Which device will
increase the number of collision domains, resulting in better throughput?
19. What are two reasons a network administrator would segment a network with a Layer 2 switch?
20. Two routers are connected with an Ethernet cable, and each router has three Ethernet switches
attached. Each switch has two computers attached. How many collision domains are there? Hint: It
might help to sketch this design on another sheet of paper.
