What statement accurately describes what a cable bend radius determines?
1-A cable bend radius is the radius of the maximum arc into which you can loop the cable without impairing data.

·         entrance facility

 

During termination of twisted pair cabling, what should be done to ensure minimal cross talk is introduced?
1-Each pair should be twisted around another pair to reduce cross talk.
2-No less than 1 inch of the cable should be exposed.
3-No more than 1 inch of the cable should be exposed.
4-Each pair should be stripped of insulation so that it doesn't get caught in the jack.

Why should you not leave more than 1 inch of exposed cable before a twisted-pair termination?
1-The exposure of the cable can cause transmission interference between wires.
2-The cable will lose its conductive properties.
3-Exposing more cable than necessary can cause corrosion of the copper wire.
4-The termination will fail over time due to oxidation.

 

·         The exposure of the cable can cause transmission interference between wires.
