A small business wants to set up a LAN to connect its computers and provide internet access. The office floor plan is a rectangle 20 m by 12 m. There are three departments: Administration (5 computers), Production (8 computers) and Sales (4 computers). The manager wants to minimise cabling cost while ensuring redundancy for the Production department. The network will use Ethernet (100BASE‑TX) and a single broadband router provides internet connectivity.

Question Parts

( a )
Recommend an appropriate logical network topology for the whole office and justify why it suits the stated requirements.
( b )
For the physical layout, propose a cabling scheme (including type of cable, maximum segment length and placement of switches) that satisfies the Ethernet standards and the redundancy requirement for Production. Explain your reasoning.
( c )
The manager asks for an IP‑addressing plan using private IPv4 addresses, with separate subnets for each department. Provide a suitable subnetting scheme, showing the network address, subnet mask and the range of usable host addresses for each department. Explain the steps you used to determine the subnet sizes.
( d )
Identify two potential security risks associated with the proposed network and suggest one mitigation measure for each risk.
