Question

You have been asked to propose a network design for a small business. The business wants it to be as cheap and low maintenance as possible. Security can be minimal, but the network must be able to support four computers that will share two printers and be able to accommodate another machine or two later. Suggest anetwork architecture and explain why.

Answer 1

A cost-effective and low-maintenance network design for a small business would be a star topology utilizing an unmanaged switch. This approach requires minimal setup and is easy to expand, with a firewall router providing basic security.

Step-by-step explanation:

For a small business network design, I recommend a simple star topology using an unmanaged switch. This is cost-effective and easy to maintain. Each of the four computers would connect to the switch via Ethernet cables. The two printers can also connect to the switch, allowing all networked computers to share them. Since the business may add more devices, an 8-port switch would provide the necessary expansion capabilities.

Why is this the preferred solution? A star topology is easy to understand and set up. An unmanaged switch requires no configuration and immediately begins working once it is powered on and devices are connected. This setup minimizes maintenance costs because unmanaged switches are generally very reliable and troubleshooting is straightforward since each device is connected to a central point. For a basic level of security, ensure the small business has a firewall router installed at the network's point of entry to protect against external threats.
