Why should you not leave more than 1 inch of exposed cable before a twisted-pair termination?
The exposure of the cable can cause transmission interference between wires.
What does backbone cabling consist of?
The cables or wireless links that provide interconnection between the entrance facility and MDF, and between the MDF and IDFs.
Which of the following is NOT a best practice when performing cable management?
