A newly hired technician has a task of terminating CAT 5 UTP cables. The networkadministrator visually examined the cables the technician terminated. Some of the cables have connectors asshown in the exhibit. What should the network administrator explain to the technician about the cables?Both cables are acceptable.*The cable in Graphic A will produce more crosstalk.The cable in Graphic A should be used in the more critical network segments.The cable in Graphic A is preferred because it will be easier to crimp the connector.********************************************************35 Which of the following increases the potential for a collision to occur?the use of an active hub instead of an intelligent hubthe use of an intelligent hub instead of an active huba reduction in the number of devices attached to the hub* an increase in the number of devices attached to the hub*****************************************************************************36.
