CompTIA Server+ SK0-005 Practice Question
During the decommissioning of an obsolete rack, a systems administrator must perform cable remediation on dozens of Category 6 network cables and two 30-amp power whips that run through overhead ladder trays in a plenum-rated ceiling. None of the conductors will be reused. Which action is the MOST appropriate to satisfy National Electrical Code (NEC) requirements and minimize fire and airflow hazards?
Cut the network and power cables flush with the rack entry point, cap the exposed conductors, and leave the remaining lengths inside the ladder trays.
Attach orange "NOT IN USE" tags to both ends of every conductor, then leave all wiring in place so it can be located easily if needed later.
Trace each cable and power whip, disconnect both ends, pull the runs completely out of the ladder tray, and send the removed material for approved recycling.
Coil the unused cables on top of the rack, secure them with Velcro straps, and leave the power whips in the tray to avoid disturbing other circuits.
