TEE practice mock · Q1A. A university plans a campus network. Explain how wired and wireless communication can be used with respect to speed, reliability and security. [5 mock marks]
Answer
| Criterion | Wired campus links | Wireless campus access |
|---|---|---|
| Speed/capacity | Dedicated switch ports and fiber backbones can provide high, predictable capacity | Capacity shared over radio; performance depends on contention, coverage and interference |
| Reliability | Stable when cables/ports and redundant uplinks are healthy | Mobility and flexible access; radio interference and coverage holes can cause variability |
| Security | Physical access control helps, but ports still need authentication/segmentation | Use authenticated encryption and managed access; radio extends beyond rooms |
| Deployment | Cabling cost and fixed access points | Supports mobile users and faster coverage changes |
| Recommended role | Servers, laboratories, inter-building backbone | Students’ phones/laptops, roaming and guest access |
Choose a hybrid: wired core/backbone and critical endpoints, with managed access points providing wireless mobility. Separate guest traffic, authenticate users and plan redundant infrastructure. Neither medium alone guarantees security or availability.
