Question 7 GCE_MODEL_QUESTIONS_VOL1 • 2017 • COMPUTER_STUDIES • essay

A new start‑up company plans to set up a local area network (LAN) for its office. The office has three departments: Administration (5 computers), Sales (8 computers), and Development (12 computers). Management wants the network to allow all computers to communicate with each other, to provide a secure link to the Internet through a single router, and to minimise the amount of cabling required while keeping the network scalable for future expansion.

Question Parts

( a )
Recommend the most suitable LAN topology for this situation. Justify your choice by discussing at least three relevant criteria such as cost, fault tolerance and scalability.
( b )
Assuming the chosen topology uses star segments centred on a switch for each department and a central backbone switch that connects the three departmental switches, calculate the minimum number of Ethernet cables required to interconnect all computers and switches. Show your reasoning.
( c )
Propose an IPv4 addressing scheme for the whole office that places each department on a separate subnet, supports up to 30 hosts per subnet, and leaves room for future growth. Provide for each department: the network address, the subnet mask, the first usable host address and the last usable host address.
