b. Refer to Fig. Q1. The IP address of Computer \( A \) is: 192.168. \( 0.2 \), subnet mask is: 255.255.255.0, MAC address is: \( 1 \mathrm{~A}: 11: 2 \mathrm{~F}: 3 \mathrm{D}: \mathrm{A4}: 2 \mathrm{~F} ; \) The IP address of Compuner B is: 172.16.0.2 subnet mask is: 255.255.0.0, MAC address is: \( 23 \times 6 \mathrm{D}: 34: 1 \mathrm{~F}: 75: 3 \mathrm{~A} ; \) The IP address of Computer \( \mathrm{C} \) is: 10.10.0.2 subnet mask is: 255.0.0.0, MAC address is: 54.91:01:D2:E4:91. Router 1 has the following configurations, eth0: IP address \( =192.168 .0 .1 / 24 \), MAC address \( =26 c A 1: B 4: 09: 36: D 1: \) eth1: IP address \( =192.168 .1 .1 / 30, \mathrm{MAC} \) address \( =62.41: 27: \mathrm{D} 1: \mathrm{F2}: \mathrm{A6c} \) eth2: IP address \( =172.16 .0 .1 / 16 \), MAC address \( = \) A1:B2.C3:D4.E:5:F6 Router 2 has the following configunations, eth0: IP address \( =192.168 .0 .2 / 24 \), MAC address \( =36: \mathrm{A} 4: \mathrm{B} 7: \mathrm{C9}: \mathrm{D} 6 . \mathrm{El} \); eth1: IP address \( =10.10 .0 .1 / 8 \), MAC address \( =\mathrm{B} 2 \mathrm{C} 1: \mathbb{E}: 2: 21: 42: 36 \) i. Deternine the maximum number of additional computer devices each of L.AN-1, LAN-2, LAN-3, LAN-4 can accommodate [4 Marks] ii. When computer \( \mathrm{A} \) sends one meseage to computer \( \mathrm{B} \) and another message to computer \( C \), show the outline of the Network and data link headers with the values of source and destination IP address of packets and MAC addresses of frames as the messages move from LAN 1 to LAN 2, L.AN1 to L.AN 3 respectively [4 Marks] iii. Illustrate how Computer \( A \) will determine that it nast use souter \( R 1 \) to forward messages to compuiter \( \mathrm{B} \) [2.5 Marks] iv. Illustrate the contents of the ARP tables of router \( \mathrm{R} 2 \) [2 Marks] v. If Conquter \( C \) was connected to Ethernet port 1 ( \( 1^{\text {a }} \) physical poit) of the swixch on L.AN 4, and router R2 on Ethernet port 2 ( \( 2^{\text {al }} \) physical port) of the sanne switch, give the populated the swixch table after all conputers have exchanged messages
