Total marks: 100

Question 1 (20 marks)

  1. (10 marks) Why we need to specify IPv4 network mask as well as the IPv4 network address for a device?
  2. (5 marks) Explain the meaning of /24 as an IPv4 network mask.
  3. (5 marks) Comment on the meaning of IPv4 subnet mask “/0”?

Submit your answer to Question 1 as <studentIDQ1>.pdf (e.g. U123456Q1.pdf)

Question 2 (20 marks)

  1. (6 marks) When delivering a packet, what are the roles of IPv4 address and the MAC address?
  2. (14 marks) We use “country code / area code / home phone number” to specify a home phone. Explain why we can or cannot use a similar structure “country code / area code / device number” to specify the address of a PC.

  1. (5 marks) Explain why you want to subdivide the network into subnets.
  2. (5 marks) What is the number of assignable addresses in a smallest subnet? What is the use of such a subnet?
  3. (20 marks) Show your design for the subnets using the following table:
  Section  Subnet Address  Mask lengthBroadcast addressGateway addressNumber of assignable addresses
  • (30 marks) Implement the network using Packet Tracer 8.0.1. Make sure that all PCs can ping each other and devices on the Internet.
    • For convenience, you may
      • attach the IP address to the name of PCs
      • attach the subnet address and mask to the switch used by the LAN
      • attach the IP address of the interface used by the router to link to the subnet
    • Assume,, and are globally routable.
    • Use one router (e.g. model 2911) as the gateway for all 3 subnets.
    • Use as the address of RInt and as the address for RF for the Internet link from RF.
    • Use /24 as the addresses for RInt and as the address for PCInt.)
    • Show at least the manager’s PC and one other PC for each subnet.
    • Link RF and RInt using a WAN Link.
    • Use Static routes and default route for routing between LAN Gateway and RInt.

Submit your answer to Q3 as <studentIDQ3>.pdf (e.g. U123456789Q3.pdf) and
