Exam 1: Scenario Identification
A company requires a network where if any single cable fails, the rest of the network remains operational. Which topology is most suitable?
Star
Centralized connection — robust to single cable failure.
Mesh
Every device connected — maximum redundancy.
Exam 2: The Star Failure Trap
Describe the effect of the central switch failing in a Star topology. [1 Mark]
⚠️ The Trap
"Only the devices connected to that switch will lose connection."
✅ The Mark Scheme
The entire network will fail, as all devices rely on the central switch to communicate.
Exam 3: Component Comparison
Which topology is typically the most expensive to install?
Star
Moderate cabling and switch cost.
Mesh
Extremely high cabling cost due to full connectivity.
