Question 1:

The users of USQ College is divided into 4 subnets as shown. The Senior Student subnet has 100 hosts, Junior Student subnet has 50 hosts, Admin subnet has 20 hosts and Teacher subnet has 4 hosts. The network diagram shows only 2 PCs per subnet for simplicity.

USQ College was assigned the network 192.168.0.0/24.

Draw a table such as the one show below and subdivide the network into subnets:

- Use the smallest subnet where possible.
- Routers use G0/0 to connect to the LAN.
- Routers use G0/1 to connect to G0/2 of another router.
- Routers use crossover cables to connect other routers using G interfaces.
- VLAN 1 of all switches should be assigned an address.
- PCs should have IP of G0/0 of the connected router as the gateway.
- The link between each router is also a subnet of its own.

You should start assigning IP to the biggest subnet first, and others in descending order of size. Use "N/A" to indicate a subnet not assigned to any group.

Senior Student subnet has been done for you:

implement the USQ College network.

- Remember to switch off the router before adding modules, and switch on again after adding modules.
- Use copper straight through cables to connect PC and Switch, Switch and router.
- Use copper straight through cables to connect PC and Switch, Switch and router.
- Use serial cable (automatically choose connection type) to join routers.

Question 2:

To demonstrate your computer network ability to your employer, you are asked to set up a simple network of 4 LANs using Packet Tracer. Your boss also hinted that a router interface can handle multiple protocols at the same time.

- LAN1: 192.168.0.0/24
- LAN2: 192.168.1.0/24
- LAN3: 2001:DB8:ACAD::/64
- LAN4: 2001:DB8:FADE::/64
- PC1 is in LAN1 with address 192.168.0.1.
- PC2 is in LAN2 with address 192.168.1.1.
- PC3 is in LAN3 with address 2001:DB8:ACAD::1.
- PC4 is in LAN4 with address 2001:DB8:FADE::1.
- Router G0/0 is in LAN1 with address 192.168.0.254 and in LAN3 with address 2001:DB8:ACAD::2.
- Router G0/1 in in LAN2 with address 192.168.1.254 and LAN4 with address 2001:DB8:FADE::2.
- Switch S1 is used to connect all LAN1 devices.
- Switch S1 is also used to connect all LAN3 devices.
- Switch S2 is used to connect all LAN2 devices.
- Switch S2 is also used to connect all LAN4 devices.

a) Implement the network topology using Packet Tracer and named it as Q2ans.pkt.

b) Can PC1 ping PC2? Why?

c) Can PC1 ping PC3? Why?

Question 3:

Ping server from PC.

Trace the PDU as it travels from PC to server and back. List the source and destination MAC addresses and IP addresses when the PDU enters and leaves a device. The first one has been done for you:

a) How many MAC does the 24 port Cisco switch used in the Packet Tracer has?

b) What is the use of the MAC and IP for VLAN 1 in a Cisco switch?

c) Will the source and destination MAC for the PDU change when the PDU moves along the path? If there is any change, describe the change(s) in less than 50 words.

d) Will the source and destination IP for the PDU change when the PDU moves along the path? If there is any change, describe the change(s) in less than 50 words.

Put your address tables and answers to a), b), c), d) in answer.txt.
