12. Refer to the graphic. What type of cabling is shown?
- STP
- UTP
- coax
- fiber
Explanation: Network cabling include different types of cables:
- UTP cable consists of four pairs of color-coded wires that have been twisted together and then encased in a flexible plastic sheath.
- STP cable uses four pairs of wires, each wrapped in a foil shield, which are then wrapped in an overall metallic braid or foil.
- Coaxial cable uses a copper conductor and a layer of flexible plastic insulation surrounds the copper conductor.
- Fiber cable is a flexible, extremely thin, transparent strand of glass surrounded by plastic insulation.
13. Refer to the graphic. What type of cabling is shown?
- STP
- UTP
- coax
- fiber
14. Which two places are most appropriate to use UTP cabling? (Choose two.)
- between buildings
- in a home office network
- where EMI is an issue in a cable TV network
- inside a school building
- in a manufacturing environment with hundreds of electrical devices
15. What does adherence to cabling standards ensure?
- data security
- no loss of signal
- no electromagnetic interference
- reliable data communications
16. Refer to the graphic. What type of cable is shown?
- crossover
- eight coax channels

20. What are two common causes of signal degradation when using UTP cabling? (Choose two.)
- installing cables in conduit
- having improper termination
- losing light over long distances
- installing low quality cable shielding
- using low quality cables or connectors
Explanation: When terminated improperly, each cable is a potential source of physical layer performance degradation.
21. What are three commonly followed standards for constructing and installing cabling? (Choose three.)
- pinouts
- cable lengths
- connector color
- connector types
- cost per meter (foot)

Explanation: According to the TIA/EIA-568 standard, which governs commercial cabling for LAN environments, several physical elements are defined to ensure consistency and performance. These include cable lengths, the specific connector types used (such as RJ-45), and the wire color-coded pin assignments, commonly referred to as pinouts.
