Answer the following questions, numbering your answers Q1, Q2, and Q3 respectively.
Q1) What is the difference between routing and forwarding?
Q2) Suppose there are three routers between a source host and a destination host.
Ignoring fragmentation, an IP datagram sent from the source host to the destination host will travel over how many interfaces?
How many forwarding tables will be indexed to move the datagram from the source to the destination?
Q3) Suppose you purchase a wireless router and connect it to your cable modem.
Also suppose that your ISP dynamically assigns your connected device (that is, your wireless router) one IP address. Also suppose that you have five PCs at home that use 802.11 to wirelessly connect to your wireless router.
How are IP addresses assigned to the five PCs?
Does the wireless router use NAT? Why or why not?

4. Consider three LANs interconnected by two routers, as shown in the following figure. a. Assign IP addresses to all of the host and router interfaces. For Subnet 1 use addresses of the form 192.168.200.xxx: for Subnet 2 uses addresses of the form 192.168.30.xxx; and for Subnet 3 use addresses of the form 192.168.100.xxx. b.

2) IP and MAC addressing. True or False. One point for each correct answer, zero points for each incorrect answer. Many of the questions refer to the following network consisting of three 10Mbps Ethernet segments, one switch, and one router. Assume all ARP tables are up-to-date unless otherwise stated. a) Consider a network consisting of Ethernets, hubs, switches, and routers. Suppose one of the hubs is replaced with a switch. Then the network administrator must redefine some IP addresses. True...
