Sample questions
01What does UTP stand for in networking cables?
- A.Unified Terminal Point
- B.Unshielded Twisted Pair
- C.Unidirectional Transfer Path
- D.Universal 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?
- A.Greater mechanical strength
- B.Higher voltage rating
- C.Lower conductor resistance
- D.Reduced 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?
- A.100 metres
- B.90 metres
- C.300 metres
- D.150 metres
Why: The maximum horizontal cable run is 90 metres, with an additional 10 metres allowed for patch cords (5m at each end).
