A field technician is deploying network cables inside an industrial facility where cables will run through ceiling air handling spaces and near heavy machinery generating high electromagnetic interference (EMI). Which TWO cable specifications or construction features should the technician select for this environment? Select TWO.
- Shielded Twisted Pair (STP) cabling to mitigate electromagnetic interferenceAnswer
- Plenum-rated jacket insulation to comply with building fire safety standardsAnswer
- CStandard Polyvinyl Chloride (PVC) outer jacketing to prevent smoke accumulation
- DUnshielded Twisted Pair (UTP) cabling to increase high-frequency signal throughput
Answer
The correct selections are Shielded Twisted Pair (STP) cabling to mitigate EMI and Plenum-rated jacket insulation to comply with building fire codes in air handling spaces.
Shielded Twisted Pair (STP) provides metallic shielding to block electromagnetic interference (EMI) from heavy machinery, while plenum-rated jacket insulation is flame-retardant and releases low smoke, meeting safety requirements for air handling plenum spaces.
