Case Study Questions on Network Topology

Q1: A university wants to set up a computer network for its campus. The network should support high-speed data transfer, easy troubleshooting, and future expansion. Which topology should they use and why?

Answer:

• The Star topology is the best choice because:
  • It allows easy expansion by adding new computers without disrupting the network.
  • High-speed data transfer is possible because each device has a dedicated link to the central hub/switch.
  • Troubleshooting is easy since failure in one device does not affect the entire network.

Q2: A manufacturing company has five factories in different locations. Each factory has its own network. The company wants to connect all factories for centralized data access and communication. Which topology is suitable?

Answer:

• A Mesh topology is ideal because:
  • It provides redundancy—if one link fails, data can be transmitted via another path.
  • Ensures high reliability for critical industrial processes.
  • However, it is expensive due to the large number of connections required.

Q3: A bank needs a secure and efficient network between its branches across multiple cities. Which topology should they implement, and what type of network will it be?

Answer:

• Topology: Hybrid topology (Combination of Mesh & Star).
• Network Type: Wide Area Network (WAN)
• Why?
  • Star topology at each branch ensures easy expansion and maintenance.
  • Mesh topology between main branches ensures high reliability and fault tolerance.
  • WAN is needed because the branches are in different cities.

Q4: A small business with 15 employees needs an internal network for file sharing and internet access. What topology should they use?

Answer:

• Topology: Star topology
• Network Type: Local Area Network (LAN)
• Why?
  • Centralized management makes troubleshooting easy.
  • Cost-effective for small-scale use.
  • Fast data transfer between devices.
