Sample questions
01What does UTP stand for in networking cables?
- AUnified Terminal Point
- BUnshielded Twisted Pair
- CUnidirectional Transfer Path
- DUniversal Transmission Protocol
Why: UTP stands for Unshielded Twisted Pair, which refers to cables with twisted pairs of wires without additional shielding.
02Which is the primary advantage of twisted pair cables over straight parallel wires?
- AGreater mechanical strength
- BHigher voltage rating
- CLower conductor resistance
- DReduced electromagnetic interference
Why: Twisting the pairs reduces electromagnetic interference by canceling out noise through the physical geometry of the twisted conductors.
03What is the maximum length for a horizontal cable run according to structured cabling standards?
- A100 metres
- B90 metres
- C300 metres
- D150 metres
Why: The maximum horizontal cable run is 90 metres, with an additional 10 metres allowed for patch cords (5m at each end).
